Mirrored External Network Traffic Monitoring with Remote Mirroring
Remote mirroring requires that you configure a remote mirroring VLAN on your physical switches. If you cannot configure a remote mirroring VLAN, consider using encapsulated remote mirroring as an alternative.
In the steps below, the mirroring source and mirroring destination are the following:
  • Mirroring source: Physical switch that forwards mirrored traffic to the virtual distributed switch
  • Mirroring destination: Virtual distributed switch that recieves mirrored traffic
Before you begin, verify that the uplink ports of the ESXi hosts that receive traffic are linked to the physical switch trunk port.

Procedure

  1. Configure the mirroring source to forward mirrored traffic to the mirroring destination.
  2. Configure the mirroring destination recieve mirrored traffic.
    1. Log in to the vSphere Web Client.
    2. Select your virtual distributed switch in the left column and then click Configure.
