Monitoring and Analyzing Switch Operation

Traffic Mirroring

Mirrored Traffic DestinationsLocal 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:

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 SourcesYou 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.
