Configure a mirroring destination on a remote switch
This step is required only if you are configuring a remote mirroring session in which the exit port is on a different switch than the monitored (source) interface.
For remote mirroring, you must configure the destination switch to recognize each mirroring session and forward mirrored traffic to an exit port before you configure the source switch. Configure the destination switch with the values you determined for remote mirroring in Determine the mirroring session and destination.
NOTE:
A remote destination switch can support up to 32 remote mirroring endpoints (exit ports connected to a destination device in a remote mirroring session.)
