Local port mirroring configuration task list
Local port mirroring takes effect only when the source ports and the monitor port are configured.
Complete these tasks to configure local port mirroring:
Task Remarks
Creating a local mirroring group Required.
Configuring source ports for a local mirroring group
Perform at least one configuration.
Configuring source CPUs for a local mirroring group
Configuring the monitor port for a local mirroring group Required.
Using the remote probe VLAN to enable local mirroring to support
multiple monitor ports
Optional.
Creating a local mirroring group
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a local mirroring
group.
mirroring-group group-id local
No local mirroring group
exists by default.
Configuring source ports for a local mirroring group
Either you can configure a list of source ports for a mirroring group in system view, or you can assign only
the current port to the mirroring group as a source port in interface view. To assign multiple ports to the
mirroring group as source ports in interface view, repeat the operation.
Configuration restrictions and guidelines
• A mirroring group can contain multiple source ports.
• On the WX5540E switching engine, one mirroring resource is used for mirroring unidirectional
traffic on a source port and two mirroring resources are used for mirroring bidirectional traffic on a
source port. A source port on the WX5540E switching engine is assigned a maximum of four
mirroring resources. Therefore, a port, when serving as a unidirectional source port, can be added
to up to four mirroring groups. When serving as a bidirectional port can be added to up to two
mirroring groups, and when serving as a bidirectional source port and two unidirectional ports can
be added to up to three mirroring groups.
Configuring source ports in system view
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure source ports for a
local mirroring group.
mirroring-group group-id
mirroring-port mirroring-port-list
{ both | inbound | outbound }
By default, no source port is
configured for a local mirroring
group.
