Traffic Mirroring
Mirrored Traffic Destinations
Local Destinations
A local mirroring traffic destination is a port on the same switch as the source
of the traffic being mirrored.
Remote Destinations
A remote mirroring traffic destination is a ProCurve switch configured to
operate as the exit switch for mirrored traffic sessions originating on other
ProCurve switches. As of June, 2007, switches capable of this operation
include the following ProCurve switches:
■ 3500yl ■ 5400zl ■ 6200yl ■ 8200zl
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 which uses
IPv4 encapsulation, if the intended 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, ProCurve strongly recommends
that you configure the exit switch for a remote mirroring session before
configuring the source switch for the same session.
Monitored Traffic Sources
You can configure mirroring for traffic entering or leaving the switch on:
■ Ports and static trunks: Provides the flexibility for mirroring on indi-
vidual ports, groups of ports, and/or static port trunks.
■ Meshed ports: Enables traffic mirroring on all ports configured for
meshing on the switch.
■ Static VLANs: Supports traffic mirroring on static VLANs configured on
the switch. This option enables easy mirroring of traffic from all ports on
a VLAN. It automatically adjusts mirroring to include traffic from newly
added ports, and to exclude traffic from ports removed from the VLAN.
