Cisco Catalyst 2960-X User Manual

PurposeCommand or Action
Specifies an interface type and identifier; enters
the interface configuration mode.
interface Interface_type stack/module/port
Example:
Switch(config)# interface gigabitethernet 1/1/4
Step 2
Attaches the DHCP Guard policy to the interface
or the specified VLANs on that interface. The
ipv6 dhcp guard [attach-policy policy_name [ vlan {vlan_ids |
add vlan_ids | except vlan_ids | none | remove vlan_ids | all} ] |
Step 3
default policy is attached if the attach-policy
option is not used.
vlan [ {vlan_ids | add vlan_ids | exceptvlan_ids | none | remove
vlan_ids | all} ]
Example:
Switch(config-if)# ipv6 dhcp guard attach-policy
example_policy
or
Switch(config-if)# ipv6 dhcp guard attach-policy
example_policy vlan 222,223,224
or
Switch(config-if)# ipv6 dhcp guard vlan 222, 223,224
Confirms that the policy is attached to the specified
interface without exiting the configuration mode.
do show running-config interface Interface_type stack/module/port
Example:
Switch#(config-if)# do show running-config gig 1/1/4
