Description

Syntax Description
Default
N/A.
Usage Guidelines
Permanent entries are retained in the database if the switch is reset or a power off/on cycle occurs. A
permanent static entry can either be a unicast or multicast MAC address. After they have been created,
permanent static entries stay the same as when they were created. If the same MAC address and VLAN
is encountered on another virtual port that is not included in the permanent MAC entry, it is handled as
a blackhole entry. The static entry is not updated when any of the following take place:
●
A VLAN identifier (VLANid) is changed.
●
A port is disabled.
●
A port enters blocking state.
●
A port goes down (link down).
A permanent static FDB entry is deleted when any of the following take place:
●
A VLAN is deleted.
●
A port mode is changed (tagged/untagged).
●
A port is deleted from a VLAN.
Permanent static entries are designated by “spm” in the flags field of the
show fdb
output. You can use
the
show fdb
command to display permanent FDB entries.
mac_addr
Specifies a device MAC address, using colon-separated bytes.
vlan_name
Specifies a VLAN name associated with a MAC address.
port_list
Specifies one or more ports or slots and ports associated with the MAC
address.
