276 ExtremeWare XOS 11.0 Command Reference Guide
FDB Commands
create fdbentry vlan ports
create fdbentry <mac_addr> vlan <vlan_name> ports <ports>
Description
Creates a permanent static FDB entry.
Syntax Description
Default
N/A.
Usage Guidelines
If more than one port number is associated with a permanent MAC entry, packets are multicast to the
multiple destinations.
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. The static entry is not updated when
any of the following take place:
• A VLAN is deleted.
• A VLAN identifier (VLANid) is changed.
• A port mode is changed (tagged/untagged).
• A port is deleted from a VLAN.
• A port is disabled.
• A port enters blocking state.
• A port goes down (link down).
Permanent static entries are designated by “spm” in the flags field of the
show fdb
output. You can use
the
show fdb permanent
command to display permanent FDB entries.
Example
The following command adds a permanent, static entry to the FDB for MAC address is 00 E0 2B 12 34
56, in VLAN
marketing on slot 2, port 4:
create fdbentry 00:E0:2B:12:34:56 vlan marketing port 2:4
