This article describes how to configure port mirroring on Open Mesh Switches.
- Open Mesh Switches
Port mirroring sends copies of packets seen on one or more ports to another port of a switch. Network administrators commonly use port mirroring to collect and analyze data on active networks and to diagnose or debug issues.
- All Open Mesh Switches support port mirroring.
- You can have up to four active, concurrent mirroring sessions on any single switch.
- You can use mirroring sessions in conjunction with Link Aggregation to mirror traffic from a LAG into another port for analysis.
1. Navigate to Manage → Switches and select a switch.
2. Click Port Settings.

- If you unmirror the destination port, the entire mirror session is torn down.
- If you unmirror any port in a two-port mirror, the entire mirror session will be torn down.
- You cannot mirror ports that are also being aggregated with each other.
- You can mirror one or more ports of an aggregation into a port that is not part of an aggregate group.
