DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Switch# configure terminal Switch(config)# ip dhcp relay information option Switch(config)# ip dhcp relay information option format circuit-id string abcd Switch(config)# 18-11 ip dhcp relay information option format-type circuit-id This command is used to configure the DHCP information circuit ID sub-option of the user-defined string. Use the no form of this command to remove the circuit ID sub-option. ip dhcp relay information option format-type circuit-id expert-udf NAME no ip dhcp relay information option format-type circuit-id Parameters expert-udf NAME Specifies the circuit ID of the specific ports to bind with the specific Option 82 profile with a maximum of 32 characters. Specifies the profile name. Default None. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline This command is only available for physical port and port channel interface configuration. Use this command to configure the per interface's vendor defined string for Option 82 information circuit ID sub-option. Example This example shows how to define expert-udf circuit-id of "abc" for ethernet 1/0/1. Switch# configure terminal Switch(config)# interface ethernet 1/0/1 Switch(config-if)# ip dhcp relay information option format-type circuit-id expert-udf abc Switch(config-if)# 18-12 ip dhcp relay information trust-all This command is used to enable the DHCP relay agent to trust the IP DHCP relay information for all interfaces. Use the no form of this command to disable the trusting on all interfaces. ip dhcp relay information trust-all no ip dhcp relay information trust-all 181
