FDB Commands
create fdbentry vlan dynamic
create fdbentry [<mac_address> | broadcast-mac | any-mac] vlan <vlan name>
dynamic [qosprofile <qosprofile> {ingress-qosprofile <inqosprofile>} |
ingress-qosprofile <inqosprofile> {qosprofile <qosprofile>}]
Description
Creates a permanent dynamic FDB entry, and associates it with an ingress and/or egress QoS profile.
Syntax Description
Default
N/A.
Usage Guidelines
This command is used to associate QoS profiles with packets received from or destined for the specified
MAC address, while still allowing the FDB entry to be dynamically learned. If you specify only the
ingress QoS profile, the egress QoS profile defaults to none, and vice-versa. If both profiles are specified,
the source MAC address of an ingress packet and the destination MAC address of an egress packet are
examined for QoS profile assignment.
The FDB entry is not actually created until the MAC address is encountered as the source MAC address
in a packet. Thus, initially the entry may not appear in the
show fdb output. Once the entry has been
learned, it is created as a permanent dynamic entry, designated by “dpm” in the flags field of the
show
fdb
output.
A dynamic entry is flushed and relearned (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 QoS setting is changed.
mac_address Specifies a device MAC address, using colon separated bytes.
broadcast-mac Specifies the broadcast MAC address. May be used as an alternate to the
colon-separated byte form of the address ff:ff:ff:ff:ff:ff.
any-mac Specifies the wildcard, permanent FDB entry used to give higher priority to an
802.1p packet.
vlan name Specifies a VLAN name associated with a MAC address.
dynamic Specifies that the entry will be learned dynamically.
qosprofile QoS profile associated with the destination MAC address of the egress port.
inqosprofile QoS profile associated with the source MAC address of the ingress port.
Support for this parameter was added in ExtremeWare 6.2.
