Displaying FDB Entries
ExtremeWare 7.2e Installation and User Guide 103
Overriding 802.1p Priority
This example associates the QoS profile qp5 with the wildcard permanent FDB entry any-mac on VLAN
v110:
create fdbentry any-mac vlan v110 dynamic ingress-qosprofile qp5
Configuring the FDB Aging Time
You can configure the again time for dynamic FDB entries using the following command:
configure fdb agingtime <seconds>
If the aging time is set to zero, all aging entries in the database are defined as static, nonaging entries.
This means they will not age out, but non-permanent static entries can be deleted if the switch is reset.
Displaying FDB Entries
To display FDB entries, use the following command:
show fdb {<mac_address> | permanent | ports <portlist> | vlan <vlan name>}
where the following is true:
• mac_address—Displays the entry for a particular MAC address.
• 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
• permanent—Displays all permanent entries, including the ingress and egress QoS profiles.
• ports <portlist>—Displays the entries for a set of ports or slots and ports.
• vlan <vlan name>—Displays the entries for a VLAN.
With no options, the command displays all FDB entries.
See the ExtremeWare 7.2e Command Reference Guide for details of the commands related to the FDB.
