DETAILED STEPS
PurposeCommand or Action
Enables privileged EXEC mode. Enter your password if prompted.enable
Step 1
Example:
Switch> enable
Verify the connection between the switches.show cdp neighbors
Example:
Switch(config-if)#show cdp neighbors
Step 2
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 3
Enable dynamic ARP inspection on a per-VLAN basis. By default,
dynamic ARP inspection is disabled on all VLANs. For vlan-range,
ip arp inspection vlan vlan-range
Example:
Switch(config)# ip arp inspection vlan 1
Step 4
specify a single VLAN identified by VLAN ID number, a range of
VLANs separated by a hyphen, or a series of VLANs separated by
a comma. The range is 1 to 4094. Specify the same VLAN ID for
both switches.
