Module configuration
You can specify a destination multilink trunking (MLT) group, a destination port or set of ports.
Interface modules support two port mirroring modes: rx (ingress, that is, inPort) and tx (egress, that
is, outPort). Configure the mirroring action globally in an access control list (ACL), or for a specific
access control entry (ACE) by using the ACE mirror actions. Configure the mirroring destination by
using an ACE.
In rx modes, when you configure the ACE mirror or ACL global options to mirror, use the ACE to
configure the mirroring destination port.
