4-1: Switching Table

■ The switching table contains MAC addresses and the switch ports on which they

were learned or statically configured.

■ Packets or frames are forwarded by looking up the destination MAC address in the

switching table. The frame is sent out the corresponding switch port.

■ The switching table entries are normally dynamically learned as packets flow. Entries

can also be statically defined.

Configuration

1. (Optional) Assign a static switching table entry:

(global) mac-address-table {dynamic | static | secure} mac-addr {vlan

vlan-id} {interface int1 [int2 ... int15] [protocol {ip | ipx | assigned}]
