Port Mirroring and Monitoring Commands port-mirroring source destination
OmniSwitch CLI Reference Guide March 2011 page 31-3
Usage Guidelines
•
You can configure a port mirroring and a port monitoring session on the same network interface
module in an OmniSwitch 10K.
•
A mirroring port can not be assigned to a tagged VLAN port.
•
When a port is configured as a mirroring port, it does not belong to any VLAN. Inbound traffic to the
mirroring port is dropped since it does not belong to any VLAN.
•
Spanning tree is disabled by default on a mirroring port.
•
Port mirroring is not supported on logical link aggregate ports. However, it is supported on individual
ports that are members of a link aggregate.
•
Execute the port mirroring source destination command to define the mirrored port and enable port
mirroring status. Use the port mirroring command to enable the port mirroring session.
•
Specify the vlan_id number of the mirroring port that is to remain unblocked when the command is
executed. The unblocked VLAN becomes the default VLAN for the mirroring port. This VLAN
handles the inbound traffic for the mirroring port. Spanning tree remains disabled on the unblocked
VLAN.
Usage Guidelines - Remote Port Mirroring
•
Remote port mirroring is supported only on OmniSwitch 10K switches.
•
Use the rpmir-vlan parameter and VLAN ID with this command to configure remote port mirroring
and to assign the VLAN ID for remote port mirroring.
•
The VLAN ID assigned for remote port mirroring cannot be assigned to a general port mirroring port.
•
There must not be any physical loop present in the remote port mirroring VLAN.
•
Source learning must be disabled or overridden on the ports belonging to the remote port mirroring
VLAN on intermediate and destination switches.
•
On OmniSwitch 10K switches the QoS redirect feature can be used to override source learning.
•
The mac-learning command can also be used to disable learning on the RPMIR VLAN ID.
