Configuring the Forwarding Table
The Forwarding Table allows you to designate forwarding treatment through
the switch for specific MAC addresses, allowing you to maintain the efficiency
and security of your network. You can search for specific MAC addresses by
the address itself or by port number. The switch learns addresses dynamically
from incoming packets and builds a table of these addresses along with their
associated ports. There are three types of MAC addresses in the forwarding
table:
Dynamic MAC addresses - which remain in the forwarding table for a
time period defined using the Forwarding Table Aging Time option in
the Switch Configuration Menu.
Static MAC addresses - which are entered manually, stored in
nonvolatile memory, and automatically placed in the forwarding table.
System MAC addresses - which are set by the system software and
cannot be modified. Each switch port has a permanent MAC address
assigned to it.
There are three types of dispositions associated with each address in the
forwarding table:
Forward - which directs packets destined for a specific MAC address to
a specific port.
Discard - which drops packets destined for a specific MAC address (and
thus provides a security function by blocking certain packets).
Local - which is for packets destined for the switch itself (such as a
“local” SNMP management packet).
