Mirroring Configuration Examples - Aruba 2530 Management And Configuration Manual

◦ You can configure only one mirroring session (destination) for each class.
◦ You can configure the same mirroring session for different classes.
• If a mirroring session is configured with a classifier-based mirroring policy on a port or VLAN interface, no
other traffic-selection criteria (MAC-based or all inbound and/or outbound traffic) can be added to the session.
Figure 52: Mirroring configuration in which only a mirroring policy is supported
• If a mirroring session is already configured with one or more traffic-selection criteria (MAC-based or all inbound
and/or outbound traffic), the session does not support the addition of a classifier-based policy.

Mirroring configuration examples

Local mirroring using traffic-direction criteria
An administrator wants to mirror the inbound traffic from workstation "X" on port A5 and workstation "Y" on port
B17 to a traffic analyzer connected to port C24 (see Figure 54: Local mirroring topology on page 299.) In this
case, the administrator chooses "1" as the session number. (Any unused session number from 1 to 4 is valid.)
Because the switch provides both the source and destination for the traffic to monitor, local mirroring can be used.
In this case, the command sequence is:
