MAC ACL Mirroring

Traffic entering an ingress port can be monitored from a mirror port connected to a data analyzer, based on specific source and destination MAC addresses. This feature supports mirroring of inbound traffic only. Outbound mirroring is not supported.

MAC ACL allows a user to specify a particular stream of data for mirroring using a filter. This eliminates the need to analyze all incoming data to the monitored port. To configure ACL mirroring, the user must perform three steps:

  1. Define a mirror port
  2. Create a MAC ACL with a mirroring clause
  3. Apply the MAC ACL on an interface
