ACL-based inbound mirroring
Brocade(config)#trunk ethernet 1/1 to 1/4
Brocade(config)#interface ethernet 1/1
Brocade(config-if-e10000-1/1)#ACL-mirror-port ethernet 1/8
Using this configuration, all trunk traffic is mirrored to port 1/8.
Limitations when configuring ACL-based mirroring with trunks
The config-trunk-ind command, as described in “Disabling or re-enabling a trunk port” on
page 712, cannot operate with ACL-based mirroring:
• If a trunk is configured with the config-trunk-ind command, ACL-based mirroring will not be
allowed.
• If the config-trunk-ind command is added to a trunk, any ports that are configured for
ACL-based mirroring will have monitoring removed and the following message is displayed.
Trunk port monitoring, if any, has been removed.
If an individual port is configured for ACL-based mirroring, you cannot add it to a trunk. If you try to
add a port that is configured for ACL-based mirroring to a trunk, the following message appears.
Note - ACL-mirror-port configuration is removed from port 2 in new trunk.
NOTE
If you want to add a port configured for ACL-based mirroring to a trunk, you must first remove the
ACL-mirror-port command from the port configuration. You can then add the port to a trunk that can
then be configured for ACL-based trunk mirroring.
Behavior of ACL-based mirroring when deleting trunks
If you delete a trunk that has ACL-based mirroring configured, the ACL-based mirroring
configuration is configured on the individual ports that made up the trunk.
For example, if a trunk is configured as shown in the following example and is then deleted from the
configuration as shown, each of the ports that previously was contained in the trunk is configured
for ACL-based mirroring.
Brocade(config)#trunk ethernet 4/1 to 4/2
Brocade(config)#trunk deploy
Brocade(config)#interface ethernet 4/1
Brocade(config-if-e10000)#ACL-mirror-port ethernet 5/3
To delete the trunk, enter the following command.
Brocade(config)#no trunk ethernet 4/1 to 4/2
The following configuration for ACL-based mirroring on ports 4/1 and 4/2 results from the trunk
being deleted.
interface ethernet 4/1
ACL-mirror-port ethernet 5/3
interface ethernet 4/2
ACL-mirror-port ethernet 5/3
