from and to a specific host, use the set cam command.

set cam {static | permanent} {multicast_mac} mod/ports.. [vlan]
set cam {static | permanent} filter {unicast_mac} vlan

Syntax Description
Defaults The default configuration has a local MAC address, spanning tree address (01-80-c2-00-00-00), and
CDP multicast address for destination port 1/3 (the supervisor engine). The default aging time for all

The vlan variable is required when you configure the traffic filter entry.
Setting the aging time to 0 disables aging.
