The following are guidelines for remote mirroring:
Configurations of remote mirroring, which might cause protocol packets to be remotely mirrored, are not recommended. Since all packet types are mirrored when you configure remote mirroring, remotely mirrored protocol packets may have undesirable affects on intermediate and destination switches. Blocking EDP (Extreme Discovery Protocol) packets on a remote mirroring VLAN (Virtual LAN) is one example of a case where you must perform an extra action to accommodate the remote mirroring of protocol packets.
create access-list remote_edp " ethernet-destination-address 00:e0:2b:00:00:00 mask ff:ff:ff:ff:ff:ff ;" "deny" conf access-list add "remote_edp" first vlan "remote_vlan"
