Configuring Additional Validation Checks on ARP
Packets
Dynamic ARP protection can be configured to perform additional validation
checks on ARP packets. By default, no additional checks are performed. To
configure additional validation checks, enter the arp protect validate command
at the global configuration level.
Syntax: [no] arp protect validate <[src-mac] | [dst-mac] | [ip]>
src-mac
dst-mac
ip
You can configure one or more of the validation checks. The following
example of the arp protect validate command shows how to configure the
validation checks for source MAC address and destination AMC address:
ProCurve(config)# arp protect validate src-mac dst-mac

Verifying the Configuration of Dynamic ARP Protection

To display the current configuration of dynamic ARP protection, including the
additional validation checks and the trusted ports that are configured, enter
the show arp protect command:
