CONFIGURING LOCAL PORT MIRRORING
Use the Mirroring & RSPAN Configuration page to
mirror traffic from any local source port to a
target port on the same switch for real-time
analysis. You can then attach a logic analyzer or
RMON probe to the target port and study the
traffic crossing the source port in a completely
unobtrusive manner.

COMMAND USAGE
General port mirroring configured on the Mirroring & RSPAN Configuration
page and ACL-based port mirroring are implemented independently. When
port mirroring is enabled on the Mirroring & RSPAN Configuration page,
mirroring will occur regardless of any configuration settings made on the
ACL Ports Configuration page (see "Filtering Traffic with Access Control
Lists" on page 96) or the ACE Configuration page (see "Configuring Access
Control Lists" on page 99).
PARAMETERS
These parameters are displayed:
◆ Session Number - A number identifying the mirror session. This
switch only supports one mirror session.
◆ Mode - Enables or disables port mirroring.
◆ Type - Select “Mirror” for local port mirroring.
◆ Port – Port identifier.
◆ Source - Sets the source port from which traffic will be mirrored.
Select one of these options:
■

the specified destination port.
