Monitoring and Analyzing Switch Operation
Traffic Mirroring
4. Configure Mirroring Sources
This action configures a source switch with the criteria for selecting the traffic
to mirror, and assigns the configured source criteria to a previously configured
mirroring session.
Traffic Selection Options
The traffic criteria includes one option from each of the following two selec-
tion criteria:
â– interface type
• port, trunk, and/or mesh
• VLAN
â– traffic direction or IP type
• all traffic inbound, outbound, or both
• ACL-filtered IP traffic type (inbound-only)
Mirroring Source Limits
For a given mirroring session you can configure any one of the following
mirroring source options:
â– multiple ports, trunks, and/or a mesh
â– One VLAN (If a VLAN is already assigned to a mirroring session, assigning
another VLAN to the same session causes the second assignment to
overwrite the first.)
â– One ACL assignment per session (For example, if you configure an ACL
as the source for mirrored traffic inbound on VLAN 1 for session 4, no
port, trunk, mesh, other ACL, or other VLAN mirroring sources can be
configured for session 4.)
