Command Usage

•The MAC Address Table contains the MAC addresses associated with each interface. Note that the Type field may include the following types:

-Learned - Dynamic address entries

-Permanent - Static entry

-Delete-on-reset - Static entry to be deleted when system is reset

•The mask should be hexadecimal numbers (representing an equivalent bit mask) in the form xx-xx-xx-xx-xx-xx that is applied to the specified MAC address. Enter hexadecimal numbers, where an equivalent binary bit “0” means to match a bit and “1” means to ignore a bit. For example, a mask of 00-00-00-00-00-00 means an exact match, and a mask of FF-FF-FF-FF-FF-FF means “any.”

•The maximum number of address entries is 8191.

Example

Console#show mac-address-table
Interface	Mac Address	Vlan	Type
---------	----------------- ----		-----------------
Eth 1/ 1	00-00-00-00-00-17	1	Learned
Eth 1/ 1	00-E0-29-94-34-DE	1	Delete-on-reset
Console#

mac-address-table aging-time

This command sets the aging time for entries in the address table. Use the no form to restore the default aging time.

Syntax
