Enabling dynamic ARP protection

To enable dynamic ARP protection for VLAN traffic on a routing switch, enter the arp-protect vlan command at the global configuration level.

Syntax:

arp-protect vlan [vlan-range]
no arp-protect vlan [vlan-range]

vlan-range: Specifies a VLAN ID or a range of VLAN IDs from one to 4094; for example, 1–200.

An example of the arp-protect vlan command is shown here:

switch(config)# arp-protect vlan 1-101
