HP VPN Firewall Appliances Network Management Configuration Guide

• The MAC address of Host B is 000f-e235-abcd and belongs to VLAN 1. For security, because this

host once behaved suspiciously on the network, add a destination blackhole MAC address entry for

the host MAC address, so all packets destined for the host are dropped.

• Set the aging timer for dynamic MAC address entries to 500 seconds.
