Enter the time service protocol that your time server uses. Not all time servers support all protocols, so you may have to use trial and error to find a protocol that works. The main differences between them are the time format.
When you select the Daytime (RFC-867) format, the Switch displays the day, month, year and time with no time zone adjustment. When you use this format it is recommended that you use a Daytime timeserver within your geographical time zone.
Time (RFC-868) format displays a 4-byte integer giving the total number of seconds since 1970/1/1 at 00:00:00.
NTP (RFC-1305) is similar to Time (RFC-868).
None is the default value. Enter the time manually. Each time you turn on the Switch, the time and date will be reset to 2022-01-01 00:00:00.
Time Server IP Address
Enter the IP address or domain name of your timeserver. The Switch searches for the timeserver for up to 60 seconds.
Time Server Sync Interval
Enter the period in minutes between each time server synchronization. The Switch checks the time server after every synchronization interval.
Current Time
This field displays the time you open this menu (or refresh the menu).
New Time (hh:mm:ss)
Enter the new time in hour, minute and second format. The new time then appears in the Current Time field after you click Apply.

Time Zone
Select the time difference between UTC (Universal Time Coordinated, formerly known as GMT, Greenwich Mean Time) and your time zone from the drop-down list box.
Daylight Saving Time
Daylight saving is a period from late spring to early fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening.
Enable the switch button if you use Daylight Saving Time.
Start Date
Configure the day and time when Daylight Saving Time starts if you selected Daylight Saving Time. The time is displayed in the 24 hour format. Here are a couple of examples:
Daylight Saving Time starts in most parts of the United States on the second Sunday of March. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in the United States you would select Second, Sunday, March and 2:00.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time zones in the European Union start using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March and the last field depends on your time zone. In Germany for instance, you would select 2:00 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).
End Date
Configure the day and time when Daylight Saving Time ends if you selected Daylight Saving Time. The time field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time ends in the United States on the first Sunday of November. Each time zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So in the United States you would select First, Sunday, November and 2:00.
Daylight Saving Time ends in the European Union on the last Sunday of October. All of the time zones in the European Union stop using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, October and the last field depends on your time zone. In Germany for instance, you would select 2:00 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).

IP Setup Overview
This chapter shows you how to configure IP settings and set up IP interfaces on the Switch using the IP Setup screens.
IP Interfaces
The Switch needs an IP address for it to be managed over the network. When the Switch (in Standalone mode) fails to obtain an IP address from a DHCP server, the default static IP address 192.168.1.1 will be automatically added and used as the Switch’s management IP address. The subnet mask specifies the network number portion of an IP address. The factory default subnet mask is 255.255.255.0.
On the Switch, an IP address is not bound to any physical ports. Since each IP address on the Switch must be in a separate subnet, the configured IP address is also known as IP interface (or routing domain). In addition, this allows routing between subnets based on the IP address without additional routers.
You can configure multiple routing domains on the same VLAN as long as the IP address ranges for the domains do not overlap. To change the IP address of the Switch in a routing domain, simply add a new routing domain entry with a different IP address in the same subnet.
You can configure up to 64 IP domains which are used to access and manage the Switch from the ports belonging to the pre-defined VLANs.
*You must configure a VLAN first before adding a management IP address. Each VLAN can have multiple management IP addresses, and you can log into the Switch through different management IP addresses simultaneously.

LABEL
Description
Username
Specify the user name (up to 32 printable ASCII characters) of a login account on the Switch. The string should not contain [ ? ], [ | ], [ ' ], [ " ], [ space ], [ , ], or [ : ].
Security Level
Select whether you want to implement authentication and/or encryption for SNMP communication from this user. Choose:
no auth – to use the user name as the password string to send to the SNMP manager. This is equivalent to the Get, Set and Trap Community in SNMP v2c. This is the lowest security level.
auth – to implement an authentication algorithm for SNMP messages sent by this user.
priv – to implement authentication and encryption for SNMP messages sent by this user. This is the highest security level.
*The settings on the SNMP manager must be set at the same security level or higher than the security level settings on the Switch.
Authentication
Select an authentication algorithm. MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used to authenticate SNMP data. SHA authentication is generally considered stronger than MD5, but is slower.
Password
Enter the password of up to 32 printable ASCII characters (except [ ? ], [ | ], [ ' ], [ " ], [ space ], [ , ], [ [ ], or [ ] ]) for SNMP user authentication.
Privacy
Specify the encryption method for SNMP communication from this user. You can choose one of the following:
DES – Data Encryption Standard is a widely used (but breakable) method of data encryption. It applies a 56-bit key to each 64-bit block of data.
AES – Advanced Encryption Standard is another method for data encryption that also uses a secret key. AES applies a 128-bit key to 128-bit blocks of data.
Password
Enter the password of up to 32 printable ASCII characters (except [ ? ], [ | ], [ ' ], [ " ], [ space ], [ , ], [ [ ], or [ ] ]) for encrypting SNMP packets.
Group
SNMP v3 adopts the concept of View-based Access Control Model (VACM) group. SNMP managers in one group are assigned common access rights to MIBs. Specify in which SNMP group this user is.
admin – Members of this group can perform all types of system configuration, including the management of administrator accounts.
read-write – Members of this group have read and write rights, meaning that the user can create and edit the MIBs on the Switch, except the user account and AAA configuration.
read-only – Members of this group have read rights only, meaning the user can collect information from the Switch.

Syslog Overview
The syslog protocol allows devices to send event notification messages across an IP network to syslog servers that collect the event messages. A syslog-enabled device can generate a syslog message and send it to a syslog server.
Syslog is defined in RFC 3164. The RFC defines the packet format, content and system log related information of syslog messages. Each syslog message has a facility and severity level. The syslog facility identifies a file in the syslog server. Refer to the documentation of your syslog program for details. The following table describes the syslog severity levels.
Syslog Severity Levels
code
severity
0
Emergency: The system is unusable.
1
Alert: Action must be taken immediately.
2
Critical: The system condition is critical.
3
Error: There is an error condition on the system.
4
Warning: There is a warning condition on the system.
5
Notice: There is a normal but significant condition on the system.
6
Informational: The syslog contains an informational message.
7
Debug: The message is intended for debug-level purposes.
