Configuring Trusted DHCP Server

Configure a trusted DHCP server on the switch using the command:
configure trusted-servers [dynamic vlan_id |{vlan} vlan_name] add server ip_address trust-for dhcp-server

If you configure one or more trusted ports, the switch assumes that all DHCP server packets on the trusted port are valid. You can configure a maximum of eight trusted DHCP servers per VLAN on the switch.

For more information about configuring trusted ports, see Configuring Trusted DHCP Ports.
Delete a trusted DHCP server using the command:
configure trusted-servers [dynamic vlan_id |vlan vlan_name] delete server ip_address trust-for dhcp-server
