ii. Use the Space bar to select the VLAN you want to mirror.

iii. Go to step 10 (page 322).

8. Use the down arrow key to move the cursor to the Action column for the individual port

interfaces and position the cursor at a port, trunk, or mesh you want to mirror.

9. Press the Space bar to select Monitor for the ports, trunks, mesh, or any combination of these

that you want mirrored.

Use the down arrow key to move from one interface to the next in the Action column. (If the

mesh or any trunks are configured, they appear at the end of the port listing.)

10. When you finish selecting interfaces to mirror, press [Enter], then press [S] (for Save) to save

your changes and exit from the screen.

11. Return to the Main Menu.

Using the CLI, you can configure a mirroring session for a destination device connected to an exit

port on either:

• The same switch as the source interface (local mirroring.)

• A different switch (remote mirroring.) The remote switch must be an HP switch offering the full

mirroring capabilities described in this chapter.

CAUTION: After you configure a mirroring session with traffic-selection criteria and a destination,

the switch immediately starts to mirror traffic to each destination device connected to an exit port.

In a remote mirroring session that uses IPv4 encapsulation, if the exit switch is not already configured

as the destination for the session, its performance may be adversely affected by the stream of

mirrored traffic. For this reason, HP Switch strongly recommends that you configure the exit switch

for a remote mirroring session before configuring the source switch for the same session.
