Monitoring Dynamic ARP Protection

When dynamic ARP protection is enabled, you can monitor and troubleshoot

the validation of ARP packets with the debug arp protect command. Use this

command when you want to debug the following conditions:

■ The switch is dropping valid ARP packets that should be allowed.

■ The switch is allowing invalid ARP packets that should be dropped.

ProCurve(config)# debug arp protect

1. ARP request is valid

"DARPP: Allow ARP request 000000-000001,10.0.0.1 for 10.0.0.2 port A1,

vlan "

2. ARP request detected with an invalid binding

"DARPP: Deny ARP request 000000-000003,10.0.0.1 port A1, vlan 1"

3. ARP response with a valid binding

"DARPP: Allow ARP reply 000000-000002,10.0.0.2 port A2, vlan 1"
