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:
WSS# 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-list | vlan vlan-id]
The mac-addr-wildcard parameter 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:
WSS# show fdb all
* = Static Entry. + = Permanent Entry. # = System Entry.
Total Matching FDB Entries Displayed = 3
