In release K.14.01 and greater, the use of ACLs to select inbound traffic in a mirroring session (using the
[ interface | vlan ]monitor ip access-group in mirror
command) has been deprecated and is replaced with classifier-based mirroring policies.

Configuration notes
Using the CLI, you can configure all mirroring options on a switch.
Using the Menu, you can configure only session 1 and only local mirroring in session 1 for traffic
in both directions on specified interfaces. (If session 1 has been already configured in the CLI for
local mirroring for inbound-only or outbound-only traffic, and you use the Menu to modify the
session 1 configuration, session 1 is automatically reconfigured to monitor both inbound and
outbound traffic on the assigned interfaces. If session 1 has been configured in the CLI with a
classifier-based mirroring policy or as a remote mirroring session, an error message is displayed
if you try to use the Menu to configure the session.)
You can use the CLI can configure sessions 1 to 4 for local or remote mirroring in any combination,
and override a Menu configuration of session 1.
You can also use SNMP configure sessions 1 to 4 for local or remote mirroring in any combination
and override a Menu configuration of session 1, except that SNMP cannot be used to configure
a classifier-based mirroring policy.
Remote mirroring endpoint and intermediate devices
The remote mirroring endpoint that is used in a remote mirroring session must be an HP switch that
supports the mirroring functions described in this chapter. (A remote mirroring endpoint consists
of the remote switch and exit port connected to a destination device.) Because remote mirroring
