❑ mac_address — Device MAC address, using
colon separated bytes.
❑ name — VLAN associated with MAC address.
❑ blackhole — Configures the MAC address as a

If more than one port number is associated with a
permanent MAC entry, packets are multicast to the
multiple destinations.
config fdb agingtime <number> Configures the FDB aging time. The range is 15
