CONFIGURING
ACL MIRRORING
After configuring ACLs, use the Security > ACL > Configure Interface (Add
Mirror) page to mirror traffic matching an ACL from one or more source
ports to a target port for real-time analysis. You can then attach a logic
analyzer or RMON probe to the target port and study the traffic crossing
the source VLAN(s) in a completely unobtrusive manner.
