Monitoring and Analyzing Switch Operation
Traffic Mirroring
Remote Mirroring: The mirroring exit port and the mirroring source inter-
face are on different switches. In this case, IPv4 encapsulation is used to
send the mirrored traffic from the source switch to the destination switch.
Source Switch: See Mirroring Source Switch .
Mirrored Traffic Destinations
Local Destinations
A local mirrored traffic destination is a port on the same switch as the source
of the traffic being mirrored.
Remote Destinations
A remote mirrored 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:
C a u t i o n
Configuring a mirroring source switch with the destination and traffic selec-
tion criteria for a given mirroring session causes the switch to immediately
begin mirroring traffic to that destination. In the case of remote mirroring,
which uses IPv4 encapsulation, if the intended exit switch is not already
configured as the destination for that 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 mirror-
ing session before configuring the source switch for that same session.
Mirrored Traffic Sources
You can designate 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.
