Configuring Trusted Ports for Dynamic ARP Protection

To configure one or more Ethernet interfaces that handle VLAN traffic as trusted ports, enter the arp-protect trust command at the global configuration level. The switch does not check ARP requests and responses received on a trusted port.


arp-protect trust <port-list>
no arp-protect trust <port-list>

Specifies a port number or a range of port numbers. Separate individual port numbers or ranges of port numbers with a comma; for example: c1-c3, c6.

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

switch(config)# arp-protect trust b1-b4, d1
