IRRORING
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.

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 101 ) or the ACE Configuration page (see "Configuring
Access Control Lists" on page 104 ).
