Time
— Enter the current time (mandatory). If SNTP has been
defined, but the SNTP server is not available, the switch uses the date
and time in this field and the
Date
field. Otherwise this information is
taken from the SNTP server.
–
System Up Time

reset.
–

Asset Tag
— Enter the
Asset Tag (0-16 Characters)
for the device.
This is the user-defined reference for the device.

IPv4 Addressing
You can assign IPv4 addresses to an interface in the following ways:
• Static Assignment
• DHCP Assignment - Default
When the interface is configured as a DHCP client (the default), it
requests an IP address from the DHCP server. It then sends Address
Resolution Protocol (ARP) packets to confirm the uniqueness of the IP
address. If the ARP response shows that the IP address is in use, the switch
sends a DHCPDECLINE message to the DHCP server, and sends another
DHCPDISCOVER packet that restarts the process.
If the DHCP server is not accessible, the device uses the default IP address
192.168.2.1.
Use the
page to configure a static device IPv4 address.
When an IP address is assigned, it is checked for uniqueness in the following
way:
• A gratuitous ARP request is sent three times every three seconds.
• If after (3+1)*3 = 12 seconds the switch has not received the ARP
response, the IP address is considered to be unique.
• During the procedure the switch has to reply to gratuitous ARP and probe
ARP requests with the validated IP address.
