DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide Default By default, information is not trusted. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline When IP DHCP relay information is trusted on an interface, the arriving packets with the GIADDR of 0 (this relay agent is the first relay of this DHCP request packet) but with relay agent information option present will be accepted. If it is not trusted, these packets will be dropped. When the IP DHCP relay information trust-all command setting is enabled, IP DHCP relay information is trusted for all interfaces. When this command setting is disabled, the trust state is determined by the interface mode command ip dhcp relay information trusted. Verify the settings by entering the show ip dhcp relay information trusted-sources command. Example This example shows how to disable the DHCP relay agent to trust all interface settings and enable trust for VLAN 100. Switch# configure terminal Switch(config)# no ip dhcp relay information trust-all Switch(config)# interface vlan 100 Switch(config-if)# ip dhcp relay information trusted Switch(config-if)# 24-14 ip dhcp local-relay vlan This command is used to enable local relay on a VLAN or a group of VLANs.
