Configuration Guidelines; Configuration Procedure; Configuration Example - HP 5920 Series Configuration Manual

An interface enabled with this feature checks the sender IP and MAC addresses in a received ARP packet
against permitted entries. If a match is found, the packet is handled correctly. If not, the packet is
discarded.

Configuration guidelines

Follow these guidelines when you configure ARP filtering:
You can configure a maximum of eight permitted entries on an interface.
•
Do not configure both the arp filter source and arp filter binding commands on an interface.
•
• If ARP filtering works with ARP detection, MFF, and ARP snooping, ARP filtering applies first.

Configuration procedure

To configure ARP filtering:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet interface
or Layer 2 aggregate interface
view.
3. Enable ARP filtering and
configure a permitted entry.
