DESCRIPTION
Enter a VLAN ID (between 1 and 4094) to be served with DHCP relay.
Select disable to deactivate the DHCP relay service in this VLAN.
Select mode 1 to activate DHCP relay service and include option 82 information in
the client DHCP requests for this VLAN.
Select mode 2 to disable DHCP relay service but include option 82 information in
the client DHCP requests. Before broadcasting, the switch adds option82
information to DHCP requests.
Use this field to specify up to 23 ASCII characters of additional information for the
switch to add to the DHCP requests that it relays to a DHCP server.
Examples of information you could add would be the name of the system or the
ISP.
Enter the IP addresses of the remote DHCP servers to which the switch should
relay DHCP requests.
Select Auto to have the system send DHCP requests to the active DHCP server
first. If the active DHCP server does not respond, the system sends the DHCP
request to the other DHCP server which then becomes the active DHCP server.
Select Both to have the switch send DHCP requests to both the primary and
secondary DHCP servers.
Specify to which DHCP server (Primary or Secondary) the system is to forward
this VLAN's DHCP request first.
Click Apply to save the changes in this screen to the system's volatile memory.
The system loses these changes if it is turned off or loses power, so use the
Config Save on the navigation panel and then the Save button to save your
changes to the non-volatile memory when you are done configuring.
Click New to create a new DHCP relay entry.
Click Cancel to begin configuring this screen afresh.
This is the index number of an entry.
