Configuring Secure Mac Addresses; Configuration Prerequisites - HP 3600 v2 Series Security Configuration Manual

Configuring secure MAC addresses

Secure MAC addresses are configured or learned in autoLearn mode and can survive link down/up
events. You can bind a secure MAC address to only one port in a VLAN.
Secure MAC addresses fall into static, sticky and dynamic secure MAC addresses.

IMPORTANT:
When the maximum number of secure MAC address entries is reached, the port changes to secure mode,
and no more secure MAC addresses can be added or learned. The port allows only frames sourced from
a secure MAC address or a MAC address configured by using the mac-address dynamic or mac-address
static command to pass through.

Configuration prerequisites

Aging timer—A sticky MAC address ages
out when its aging timer expires, but whether
it is immediately deleted depends on the
aging delay setting.
Aging delay—If aging delay is disabled, the
system deletes the sticky MAC address
immediately after the aging timer expires. If
aging delay is enabled, the system deletes
the sticky MAC address if no data traffic is
from the secure source MAC address before
the delay expires.
