■
You can remove individual MAC addresses from selected ports.
Typically, this action is only applied to the removal of static addresses
because the module can quickly relearn dynamic addresses that you
remove.
■
A static address is never aged from the address table and it cannot be
learned dynamically on a different port until it is removed from the
port on which it is configured as a static address.
■
If a station whose address is statically-configured on one port is moved
to a different port, the module discards all received frames as a
security measure and increments a statistical counter. (From the
bridge display
of the Administration Console, see the
rxSecurityDiscs
field. From the Bridge Display option on the Web
Management interface, see the Received Security Discards column.)
■
The number of static MAC addresses that you can configure depends
on the availability of module resources. You can configure up to 16
static addresses minimum.
■
If you select closed VLAN mode, the address space is divided
dynamically between the VLANs.
■
The process of aging addresses differs slightly between Layer 2
Switching Modules and Multilayer Switching Modules. See “Address
Aging” next in this chapter for more information.
■
If you have multiple ports associated with a trunk, the addresses that
are defined for the anchor port apply to all ports in the trunk.
