Display FDB Entries

Display FDB entries using the following command:
show fdb {blackhole {netlogin [all | mac-based-vlans]} | netlogin [all | mac-based-vlans] | permanent {netlogin [all | mac-based-vlans]} | mac_addr {netlogin [all | mac-based-vlans]} | ports port_list {netlogin [all | mac-based-vlans]} | vlan vlan_name | vlan_list {netlogin [all | mac-based-vlans]} | {{vpls} {vpls_name}}}
Note

Note

The MAC-based VLAN netlogin parameter applies only for Summit family switches and BlackDiamond 8800 series switches. See Network Login for more information.
With no options, this command displays all FDB entries. (The age parameter does not show on the display for the backup MSM/MM on modular switches; it does show on the display for the primary MSM/MM.)
