2-11 

group-id: DHCP server group number to be correlated, in the range of 0 to 19. The specified server 

group must be an existing group containing at least a DHCP server. 

Use the dhcp relay server-select command to correlate specified interface(s) to a specified DHCP 

server group.  

Use the undo dhcp relay server-select command to remove a configured correlation. 

By default, no DHCP server group is correlated with an interface on the relay agent. 

Note that an interface on the relay agent can only be correlated to one DHCP server group, and a newly 

configured correlation overwrites the previous one. If the server group in the new correlation does not 

exist, the new configuration will not work. The interface still maintains the previous correlation.

Use the dhcp select relay command to enable the relay agent on the current interface. Upon receiving 

requests from an enabled interface, the relay agent will forward these requests to outside DHCP 

servers for IP address allocation. 

Use the undo dhcp select relay command to restore the default. 

After DHCP is enabled, the DHCP server is enabled on an interface by default. That is, upon receiving a 

client’s request from the interface, the DHCP server allocates an IP address from the DHCP address 

pool to the client.
