Displaying Forwarding Database Information

You can display the forwarding database size and the entries contained in the database.

Displaying the Size of the Forwarding Database

To display the number of entries contained in the forwarding database, use the following command:

show fdb count {perm static dynamic} [vlan vlan-id]

For example, to display the number of dynamic entries that the forwarding database contains, type the following command:

23x0# show fdb count dynamic

Total Matching Entries = 2

Displaying Forwarding Database Entries

To display the entries in the forwarding database, use either of the following commands:

show fdb [mac-addr-wildcard [vlan vlan-id]]

show fdb {perm static dynamic system all} [port port-listvlan vlan-id]

The mac-addr-wildcardparameter can be an individual address, or a portion of an address with the asterisk (*) wildcard character representing from 1 to 5 bytes. The wildcard allows the parameter to indicate a list of MAC addresses that match all the characters except the asterisk.

Use a colon between each byte in the address (for example, 11:22:33:aa:bb:cc or 11:22:33:*). You can enter the asterisk (*) at the beginning or end of the address as a wildcard, on any byte boundary.

To display all entries in the forwarding database, type the following command:

23x0# show fdb all

* = Static Entry. + = Permanent Entry. # = System Entry.
VLAN	TAG	Dest MAC/Route Des [CoS]		Destination Ports	[Protocol Type]
----	----	------------------ -----		-----------------------------------------
1		00:01:97:13:0b:1f		1	[ALL]
1		aa:bb:cc:dd:ee:ff	*	3	[ALL]
1		00:0b:0e:02:76:f5		1	[ALL]

Total Matching FDB Entries Displayed = 3

To display all entries that begin with 00, type the following command:

23x0# show fdb 00:*

* = Static Entry. + = Permanent Entry. # = System Entry.
VLAN	TAG	Dest MAC/Route Des [CoS]	Destination Ports	[Protocol Type]
----	----	------------------ -----	-----------------------------------------
1		00:01:97:13:0b:1f	1	[ALL]
1		00:0b:0e:02:76:f5	1	[ALL]

Total Matching FDB Entries Displayed = 2
