Monitoring and Analyzing Switch Operation
Traffic Mirroring
■ Interface type
• Port, trunk, and/or mesh
• VLAN
• Switch (global configuration level)
■ Traffic direction and selection criteria
• All inbound and/or outbound traffic on a port or VLAN interface
• Only inbound IP traffic selected with an ACL (deprecated in software
release K.14.01 and greater)
• Only inbound IPv4 or IPv6 traffic selected with a classifier-based
mirroring policy
• All inbound and/or outbound traffic selected by MAC source and/or
destination address
The different ways to configure traffic-selection criteria on a monitored
interface are described in the following sections:
■ “Selecting All Inbound/Outbound Traffic to Mirror” on page B-57
■ “Selecting Inbound Traffic Using an ACL (Deprecated)” on page B-62
■ “Selecting Inbound/Outbound Traffic Using a MAC Address” on page B-63
■ “Selecting Inbound Traffic Using Advanced Classifier-Based Mirroring” on
page B-66
Mirroring-Source Restrictions
In a mirroring session, you can configure any of the following sources of
mirrored traffic:
■ Multiple port and trunk, and/or mesh interfaces
■ One VLAN
If you configure a VLAN as the source interface in a mirroring session and
assign a second VLAN to the session, the second VLAN overwrites the first
VLAN as the source of mirrored traffic.
■ One classifier-based policy
If you configure a mirroring policy on a port or VLAN interface to mirror
inbound traffic in a session, you cannot configure a port, trunk, mesh,
ACL, or VLAN as an additional source of mirrored traffic in the session.
■ Up to 320 MAC addresses (used to select traffic according to source and/
or destination MAC address) in all mirroring sessions configured on a
switch
