Configure Relay Agent Suboptions

In this example, circuit-id is 500, and remote-id is hello.

1. Configure the circuit-id and remote-id relay agent information options in switch 2.

   SEFOS# configure terminal
   SEFOS(config)# interface vlan 1
   SEFOS(config-if)# ip dhcp relay circuit-id 500
   SEFOS(config-if)# ip dhcp relay remote-id hello
   SEFOS(config-if)# end

2. View the relay agent information.

   SEFOS# show ip dhcp relay information

   The output in the switch is:

   Dhcp Relay                                   : Enabled
   Dhcp Relay Servers only                  : Enabled
    
   DHCP server                                 : 20.0.0.1
    
   Dhcp Relay RAI option                    : Enabled
   Default Circuit Id information             : router-index
   Debug Level                                  : 0x1
    
   No of Packets inserted RAI option               : 0
   No of Packets inserted circuit ID suboption     : 0
   No of Packets inserted remote ID suboption      : 0
   No of Packets inserted subnet mask suboption    : 0
   No of Packets dropped                           : 0
   No of Packets which did not inserted RAI option : 0
    
   Interface  vlan1
   Circuit ID : 500
   Remote  ID : hello

   • Alternatively, if you want to view just the information specified for VLAN 1, use the following command:

     SEFOS# show ip dhcp relay information vlan 1
      
     Interface    vlan1
     Circuit ID : 500
     Remote  ID : hello

   Note - Configuration of the DHCP relay circuit ID should be greater than the value of the macro DHRL_MAX_L3_IF_INDEX. The value of the macro DHRL_MAX_L3_IF_INDEX is different for SEFOS packages. For the METRO package the value of the macro is 1136 and for the enterprise package the value of macro is 160.
