Auto PD Recovery (for PoE models only)
Things can go wrong with any network devices. A PD (for example, IP camera) may slow down or freeze and need to be restarted if it is overworked or a bug causes a memory leak. When a connected PD ceases to respond, Automatic PD Recovery allows the Switch to restart the PD by turning it off and on without the need for on-site troubleshooting.
This screen lets you turn on automatic PD recovery on the Switch and its Ethernet ports. You can configure whether the Switch uses LLDP or ping to check the current status of a connected PD.
The ping is sent through the Switch's default management IP address to the designated port. To ping the PD, the port must share the same VLAN as the Switch's management VLAN.
Auto PD Recovery Application
The PD may stop responding to the Switch’s detection over ping or LLDP during firmware upgrade. Disable the Auto PD Recovery function to prevent damage to the PD caused by a power cutoff during firmware upgrade.
The following table describes the labels in this screen.
label | description |
|---|---|
Active | Select this option to enable Auto PD Recovery on the Switch. |
Port | This field displays the index number of a port on the Switch. |
* | Settings in this row apply to all ports. Use this row only if you want to make some settings the same for all ports. Use this row first to set the common settings and then make adjustments on a port-by-port basis. Changes in this row are copied to all the ports as soon as you make them. |
Active | Select Active to enable Auto PD Recovery on the ports. |
Mode | Select LLDP to have the Switch passively monitor current status of the connected PD by reading LLDP packets from the PD on the port. The Switch also sends out LLDP packets to the PD to update the Switch Neighbor table on the PD. Select Ping to have the Switch ping the IP address of the connected PD to test whether the PD is reachable or not. Select ONVIF to have the Switch passively monitor current status of the connected ONVIF-compatible PD by reading ONVIF packets from the PD on the port.  Make sure to enable the ONVIF feature on the Switch. |
Neighbor Name | If Mode is set to LLDP, the system name of the connected PD displays automatically. |
Neighbor IP | If Mode is set to Ping and the PD supports LLDP, the connected PD’s IPv4 or IPv6 address to which the Switch sends ping requests will display automatically. If not, enter the IP address manually. |
Test | Click Test to have the Switch test the connection by sending a ping request to the IP address. |
Polling Interval (sec) | Specify the number of seconds the Switch waits for a response before sending another ping request. For example, the Switch will try to detect the PD status by performing ping requests every 20 seconds. |
Polling Count | Specify how many times the Switch is to resend a ping request before considering the PD unreachable. For example, If there is no ping reply from the PD after the Polling Interval (sec) has elapsed, Polling Count starts from 1. After Polling Count reaches 3, the PD Health status LED will turn to red in the MONITOR > Neighbor > Neighbor screen. The Switch will then perform your choice in the Action field. |
Action | Set the action to take when the connected PD has stopped responding. Select Reboot-Alarm to have the Switch turn OFF the power of the connected PD (the connecting port is detected as link-down) and turn it back ON again to restart the PD after sending an SNMP trap and generating a log message. PD entry disappears from the Switch’s LLDP table and the Select Alarm to have the Switch send an SNMP trap and generate a log message. |
Resume Polling Interval (sec) | Specify the number of seconds the Switch waits before monitoring the PD status again after it restarts the PD on the port. |
PD Reboot Count | Specify how many times the Switch attempts to restart the PD on the port. The PD Reboot Count will reset • as soon as a ping is successful, • or when any modification to the Auto PD Recovery screen is applied, • or after restarting the Switch. |
Resume Power Interval (sec) | Specify the number of seconds the Switch waits before supplying power to the connected PD again after it restarts the PD on the port. |
Apply | Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. |
Cancel | Click this to reset the values in this screen to their last-saved values. |
In the event of a PD performing firmware upgrade, the PD may stop responding to ping or fail to provide LLDP packets for an extended period of time. When the Switch resets power to the PD before firmware upgrade is finished, it may permanently damage the PD or require a hard reset to recover it. It is strongly advised to disable the Switch's Auto PD Recovery function before upgrading the PD's firmware. This will prevent damage caused by a power cutoff.Green Ethernet Overview
Green Ethernet reduces switch port power consumption in the following ways.
IEEE 802.3az Energy Efficient Ethernet (EEE)
If EEE is enabled, both sides of a link support EEE and there is no traffic, the port enters Low Power Idle (LPI) mode. LPI mode turns off some functions of the physical layer (becomes quiet) to save power. Periodically the port transmits a REFRESH signal to allow the link partner to keep the link alive. When there is traffic to be sent, a WAKE signal is sent to the link partner to return the link to active mode.
Auto Power Down
Auto Power Down turns off almost all functions of the port’s physical layer functions when the link is down, so the port only uses power to check for a link up pulse from the link partner. After the link up pulse is detected, the port wakes up from Auto Power Down and operates normally.
Short Reach
Traditional Ethernet transmits all data with enough power to reach the maximum cable length. Shorter cables lose less power, so Short Reach saves power by adjusting the transmit power of each port according to the length of cable attached to that port.
Green Ethernet
EEE, Auto Power Down and Short Reach are NOT supported on an uplink port.The following table describes the labels in this screen.

Link Aggregation Overview
Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link. However, the more ports you aggregate then the fewer available ports you have. A trunk group is one logical link containing multiple ports.
The beginning port of each trunk group must be physically connected to form a trunk group.
The Switch supports both static and dynamic link aggregation.
In a properly planned network, it is recommended to implement static link aggregation only. This ensures increased network stability and control over the trunk groups on your Switch.Dynamic Link Aggregation
The Switch adheres to the IEEE 802.3ad standard for static and dynamic (LACP) port trunking.
The IEEE 802.3ad standard describes the Link Aggregation Control Protocol (LACP) for dynamically creating and managing trunk groups.
When you enable LACP link aggregation on a port, the port can automatically negotiate with the ports at the remote end of a link to establish trunk groups. LACP also allows port redundancy, that is, if an operational port fails, then one of the “standby” ports become operational without user intervention. Please note that:
• You must connect all ports point-to-point to the same Ethernet switch and configure the ports for LACP trunking.
• LACP only works on full-duplex links.
• All ports in the same trunk group must have the same media type, speed, duplex mode and flow control settings.
Configure trunk groups or LACP before you connect the Ethernet switch to avoid causing network topology loops.
Link Aggregation ID
LACP aggregation ID consists of the following information:
System Priority | MAC address | key | port priority | port number |
|---|---|---|---|---|
0000 | 00-00-00-00-00-00 | 0000 | 00 | 0000 |
System Priority | MAC address | key | port priority | port number |
|---|---|---|---|---|
0000 | 00-00-00-00-00-00 | 0000 | 00 | 0000 |
Algorithm Types Limitation
The maximum number of link aggregation algorithm types (Criteria) that can link up at the same time depends on your Switch model. See PORT > Link Aggregation > Link Aggregation Status for the list of Criteria that your Switch currently supports.
The following table shows the maximum number of link aggregation algorithm types that can link up at the same time.
model | link aggregation algorithm types (maximum) |
|---|---|
GS1350 Series | 2 |
For example, if your Switch has two link aggregation algorithm types that are currently online. The third link aggregation algorithm type can only go online when one of the online link aggregation algorithm type goes offline.
Link Aggregation Status
See Link Aggregation Overview for more information.
The following table describes the labels in this screen.
LABEL | DESCRIPTION |
|---|---|
Group ID | This field displays the group ID to identify a trunk group, that is, one logical link containing multiple ports. |
Enabled Ports | These are the ports you have configured in the Link Aggregation Setting screen to be in the trunk group. The port numbers displays only when this trunk group is activated and there is a port belonging to this group. |
Synchronized Ports | These are the ports that are currently transmitting data as one logical link in this trunk group. |
Aggregator ID | Link Aggregator ID consists of the following: system priority, MAC address, key, port priority and port number.The ID displays only when there is a port belonging to this trunk group and LACP is also enabled for this group. |
Criteria | This shows the outgoing traffic distribution algorithm types used in this trunk group. Sending of packets are from the same source and/or to the same destination over the same link within the trunk. src-mac means the Switch distributes traffic based on the packet’s source MAC address. dst-mac means the Switch distributes traffic based on the packet’s destination MAC address. src-dst-mac means the Switch distributes traffic based on a combination of the packet’s source and destination MAC addresses. src-ip means the Switch distributes traffic based on the packet’s source IP address. dst-ip means the Switch distributes traffic based on the packet’s destination IP address. src-dst-ip means the Switch distributes traffic based on a combination of the packet’s source and destination IP addresses. To find the number of link aggregation algorithm types that can link up at the same time, see Algorithm Types Limitation . |
Status | This field displays how these ports were added to the trunk group. It displays: • Static – if the ports are configured as static members of a trunk group. • LACP – if the ports are configured to join a trunk group through LACP. |

LLDP Overview
The LLDP (Link Layer Discovery Protocol) is a layer 2 protocol. It allows a network device to advertise its identity and capabilities on the local network. It also allows the device to maintain and store information from adjacent devices which are directly connected to the network device. This helps an administrator discover network changes and perform necessary network reconfiguration and management. The device information is encapsulated in the LLDPDUs (LLDP data units) in the form of TLV (Type, Length, Value). Device information carried in the received LLDPDUs is stored in the standard MIB.
The Switch supports these basic management TLVs.
• End of LLDPDU (mandatory)
• Chassis ID (mandatory)
• Port ID (mandatory)
• Time to Live (mandatory)
• Port Description (optional)
• System Name (optional)
• System Description (optional)
• System Capabilities (optional)
• Management Address (optional)
The Switch also supports the IEEE 802.1 and IEEE 802.3 organizationally-specific TLVs.
IEEE 802.1 specific TLVs:
• Port VLAN ID TLV (optional)
• Port and Protocol VLAN ID TLV (optional)
IEEE 802.3 specific TLVs:
• MAC/PHY Configuration/Status TLV (optional)
• Power via MDI TLV (optional, For PoE models only)
• Link Aggregation TLV (optional)
• Maximum Frame Size TLV (optional)
The optional TLVs are inserted between the Time To Live TLV and the End of LLDPDU TLV.
LLDP Overview
LLDP-MED Overview
LLDP-MED (Link Layer Discovery Protocol for Media Endpoint Devices) is an extension to the standard LLDP developed by the Telecommunications Industry Association (TIA) TR-41.4 subcommittee which defines the enhanced discovery capabilities, such as VoIP applications, to enable network administrators manage their network topology application more efficiently. Unlike the traditional LLDP, which has some limitations when handling multiple application devices, the LLDP-MED offers display of accurate physical topology, interoperability of devices, and easy trouble shooting for mis-configured IP addresses. There are three classes of endpoint devices that the LLDP-MED supports:
Class I: IP Communications Controllers or other communication related servers
Class II: Voice Gateways, Conference Bridges or Media Servers
Class III: IP-Phones, PC-based Softphones, End user Communication Appliances supporting IP Media
The following figure shows that with the LLDP-MED, network connectivity devices (NCD) like Switches and Routers will transmit LLDP TLV to endpoint device (ED) like IP Phone first (1), to get its device type and capabilities information, then it will receive that information in LLDP-MED TLV back from endpoint devices (2), after that the network connectivity devices will transmit LLDP-MED TLV (3) to provision the endpoint device to such that the endpoint device’s network policy and location identification information is updated. Since LLDPDU updates status and configuration information periodically, network managers may check the result of provision through remote status. The remote status is updated by receiving LLDP-MED TLVs from endpoint devices.

PoE Status (for PoE models only)
A powered device (PD) is a device such as an access point or a switch, that supports PoE (Power over Ethernet) so that it can receive power from another device through an Ethernet port.
You can also set priorities so that the Switch is able to reserve and allocate power to certain PDs.
The PoE (Power over Ethernet) devices that supply or receive power and their connected Ethernet cables must all be completely indoors.To view the current amount of power that PDs are receiving from the Switch, click PORT > PoE Setup > PoE Status.
The following table describes the labels in this screen.
label | description |
|---|---|
PoE Mode | This field displays the power management mode used by the Switch, whether it is in Classification or Consumption mode. |
Total Power (W) | This field displays the total power the Switch can provide to the connected PoE-enabled devices on the PoE ports. |
PoE Usage (%) | This field displays the amount of power currently being supplied to connected PoE devices (PDs) as a percentage of the total PoE power the Switch can supply. When PoE usage reaches 100%, the Switch will shut down PDs one-by-one according to the PD priority which you configured in PORT > PoE Setup > PoE Setup. |
PoE Usage Threshold (%) | This field displays the percentage of PoE usage. The Switch will generate a trap and/or a log when the usage exceeds the specified threshold. |
Consuming Power (W) | This field displays the amount of power the Switch is currently supplying to the connected PoE-enabled devices. |
Allocated Power (W) | This field displays the total amount of power the Switch (in classification mode) has reserved for PoE after negotiating with the connected PoE devices. It shows NA when the Switch is in consumption mode. Consuming Power (W) can be less than or equal but not more than the Allocated Power (W). |
Remaining Power (W) | This field displays the amount of power the Switch can still provide for PoE. |
Port | This is the port index number. |
State | This field shows which ports can receive power from the Switch. • Disable – The PD connected to this port cannot get power supply. • Enable – The PD connected to this port can receive power. |
Class | This shows the power classification of the PD. Each PD has a specified maximum power that fall under one of the classes. The Class is a number from 0 to 8, where each value represents the range of power that the Switch provides to the PD. The power ranges in PoE standards are as follows. • Class 0 – default: 0.44 W to 15.4 W. • Class 1 – default: 0.44 W to 4 W. • Class 2 – default: 0.44 W to 7 W. • Class 3 – default: 0.44 W to 15.4 W. • Class 4 – default: 0.44 W to 30 W. • Class 5 – default: 0.45 W to 45 W. • Class 6 – default: 0.45 W to 60 W. You can extend or set a limit on the maximum power the connected PD can use on a port in PORT > PoE Setup > PoE Setup. |
Priority | When the total power requested by the PDs exceeds the total PoE power budget on the Switch, you can set the priority to allow the Switch to provide power to ports with higher priority first. • Critical has the highest priority. • High has the Switch assign power to the port after all critical priority ports are served. • Low has the Switch assign power to the port after all critical and high priority ports are served. |
Power-Up | This field displays the PoE setting the Switch uses to provide power on this port. |
Consuming Power (W) | This field displays the current amount of power consumed by the PD from the Switch on this port. |
Max Power (W) | This field displays the maximum amount of power the PD could use from the Switch on this port. This field displays “–” if the maximum power is not specified in PORT > PoE Setup > PoE Setup. |
Time-Range State | This field shows whether or not the port currently receives power from the Switch according to its schedule. • It shows “In” followed by the time range name if PoE is currently enabled on the port. • It shows “Out” if PoE is currently disabled on the port. • It shows “–” if no schedule is applied to the port. PoE is enabled by default. |
Action | Click Reset to perform a power cycle on the port currently supplying PoE power to the connected PoE-enabled device. |
PoE Setup
Use this screen to set the PoE power management mode, priority levels, power-up mode and the maximum amount of power for the connected PDs.
The following table describes the labels in this screen.
label | description |
|---|---|
PoE Mode | Select the power management mode you want the Switch to use. • Classification – Select this if you want the Switch to reserve the maximum power for each PD according to the PD’s power class and priority level. If the total power supply runs out, PDs with lower priority do not get power to function. In this mode, the maximum power is reserved based on what you configure in Max Power or the standard power limit for each class. • Consumption – Select this if you want the Switch to supply the actual power that the PD needs. The Switch also allocates power based on a port’s Max Power and the PD’s power class and priority level. The Switch puts a limit on the maximum amount of power the PD can request and use. In this mode, the default maximum power that can be delivered to the PD is 30 W (IEEE 802.3at Class 4) or 22 W (IEEE 802.3af Classes 0 to 3). |
Continuous PoE | Select ON to guarantee continuous power supply to the connected PDs while the Switch is restarting after a warm reboot. The Switch will NOT perform a power cycle on the connected PDs. If you do a cold reboot, the Switch also restarts the connected PDs. |
MIB Trap | The Switch sends traps (monitoring event notification) to an SNMP (Simple Network Management Protocol) manager when an event occurs. Select ON to allow sending of MIB Trap when the following situations occur: • Situation 1 – Trap sent whenever a PoE port status change occurs (PoE port delivers power or delivers no power to a PD (powered device) • Situation 2 – Trap sent in cases where the total power usage exceeds the PoE usage threshold • Situation 3 – Trap sent if total usage power decreases below the PoE usage threshold (only if previous total power usage exceeded the PoE usage threshold and a trap was sent). If the MIB Trap is ON, you must also configure:• SNMP trap destination (SYSTEM > SNMP > SNMP), SNMP trap group (SYSTEM > SNMP > SNMP Trap Group) and SNMP trap port (SYSTEM > SNMP > SNMP Trap Port) for Situation 1 • SNMP trap destination and SNMP trap group for Situation 2 and Situation 3. See SNMP Overview for more information on configuring SNMP. |
PoE Usage Threshold (%) | Enter a number ranging from 1 to 99 to set the threshold. The Switch will generate a trap and/or log when the actual PoE usage is higher than the specified threshold. |
Port | This is the port index number. |
* | Settings in this row apply to all ports. Use this row only if you want to make some settings the same for all ports. Use this row first to set the common settings and then make adjustments on a port-by-port basis. Changes in this row are copied to all the ports as soon as you make them. |
Active | Select this to provide power to a PD connected to the port. If left unchecked, the PD connected to the port cannot receive power from the Switch. |
Priority | When the total power requested by the PDs exceeds the total PoE power budget on the Switch, you can set the PD priority to allow the Switch to provide power to ports with higher priority. Select Critical to give the highest PD priority on the port. Select High to set the Switch to assign the remaining power to the port after all critical priority ports are served. Select Low to set the Switch to assign the remaining power to the port after all critical and high priority ports are served. |
Power-Up | Set how the Switch provides power to a connected PD at power-up. 802.3af – the Switch follows the IEEE 802.3af Power over Ethernet standard to supply power to the connected PDs during power-up. Legacy – the Switch can provide power to the connected PDs that require high inrush currents at power-up. Inrush current is the maximum, instantaneous input current drawn by the PD when first turned on. Pre-802.3at – the Switch initially offers power on the port according to the IEEE 802.3af standard, and then switches to support the IEEE 802.3at standard within 75 milliseconds after a PD is connected to the port. Select this option if the Switch is performing 2-event Layer-1 classification (PoE+ hardware classification) or the connected PD is NOT performing Layer 2 power classification using Link Layer Discovery Protocol (LLDP). 802.3at – the Switch supports the IEEE 802.3at High Power over Ethernet standard and can supply power of up to 30W per Ethernet port. IEEE 802.3at is also known as PoE+ or PoE Plus. An IEEE 802.3at compatible device is referred to as Type 2. Power Class 4 (High Power) can only be used by Type 2 devices. If the connected PD requires a Class 4 current when it is turned on, it will be powered up in this mode. Force-802.3at – the Switch offers power of up to 33 W on the port without performing PoE hardware classification. Select this option if the connected PD does not comply with any PoE standard and requests power higher than a standard power limit. |
Max Power (mW) | Specify the maximum amount of power the PD could use from the Switch on this port. If you leave this field blank, the Switch refers to the standard or default maximum power for each class. |
LLDP Power Via MDI | Select this to have the Switch negotiate PoE power with the PD connected to the port by transmitting LLDP Power Via MDI TLV frames. This helps the Switch allocate less power to the PD on this port. The connected PD must be able to request PoE power through LLDP. The Power Via MDI TLV allows PoE devices to advertise and discover the MDI power support capabilities of the sending port on the remote device. • Port Class • MDI Supported • MDI Enabled • Pair Controllable • PSE Power Pairs • Power Class |

Port Setup
Use this screen to configure Switch port settings.
The following table describes the labels in this screen.
label | description |
|---|---|
Port | This is the port index number. |
* | Settings in this row apply to all ports. Use this row only if you want to make some settings the same for all ports. Use this row first to set the common settings and then make adjustments on a port-by-port basis. Changes in this row are copied to all the ports as soon as you make them. |
Active | Select this checkbox to enable a port. The factory default for all ports is enabled. A port must be enabled for data transmission to occur. |
Name | Enter a descriptive name that identifies this port. You can enter up to 128 printable ASCII characters except [ ? ], [ | ], [ ' ] or [ " ]. Due to space limitation, the port name may be truncated in some Web Configurator screens. |
Speed/Duplex | Select the speed and the duplex mode of the Ethernet connection on this port. Choices are Auto, 10-an (10M/auto-negotiation), 10M/Half Duplex, 10M/Full Duplex, 100-an (100M/auto-negotiation), 100M/Half Duplex, 100M/Full Duplex and 1G/Full Duplex (Gigabit connections only). Selecting Auto (auto-negotiation) allows one port to negotiate with a peer port automatically to obtain the connection speed and duplex mode that both ends support. When auto-negotiation is turned on, a port on the Switch negotiates with the peer automatically to determine the connection speed and duplex mode. If the peer port does not support auto-negotiation or turns off this feature, the Switch determines the connection speed by detecting the signal on the cable and using half duplex mode. When the Switch’s auto-negotiation is turned off, a port uses the pre-configured speed and duplex mode when making a connection, therefore requiring you to make sure that the settings of the peer port are the same in order to connect. |
Extended Range | Select this checkbox to extend the PoE range up to 250 meters. After you enable this feature, the port will transfer data at a rate up to10 Mbps in full duplex mode. If a PD is connected to the port, the Switch follows the IEEE 802.3at PoE+ standard to supply power to the connected PD during power-up. Maximum PoE power that can be supplied to a PD at 250 m is 15 W.If you enable extended range on a port after the connected PD starts up completely, you must disable PoE and enable it again or disconnect and reconnect the cable to the port for extended mode to take effect.The port speed and duplex mode you previously configured will be applied automatically when the extend range feature is disabled. |
Flow Control | A concentration of traffic on a port decreases port bandwidth and overflows buffer memory causing packet discards and frame losses. Flow Control is used to regulate transmission of signals to match the bandwidth of the receiving port. The Switch uses IEEE802.3x flow control in full duplex mode. IEEE802.3x flow control is used in full duplex mode to send a pause signal to the sending port, causing it to temporarily stop sending signals when the receiving port memory buffers fill. Select Flow Control to enable it. |
802.1p Priority | This priority value is added to incoming frames without a (802.1p) priority queue tag. |
Apply | Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. |
Cancel | Click Cancel to begin configuring this screen afresh. |
