ExtremeWare XOS 10.1 Command Reference Guide 221
create fdbentry vlan ports
create fdbentry <mac_addr> vlan <vlan_name> ports [<portlist> | all]
Description
Creates a permanent static FDB entry, and optionally associates it with an ingress and/or egress QoS
profile.
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. The stand-alone switches can
support a maximum of 64 permanent entries, and the modular switches support a maximum of 254
permanent entries.
After they have been created, permanent static entries stay the same as when they were created. If the
same MAC address 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 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, including their QoS profile
associations.
mac_addr Specifies a device MAC address, using colon-separated bytes.
vlan_name Specifies a VLAN name associated with a MAC address.
