Field Description

Analyzer name

Displays the name of the analyzer.

Output interface

Specifies a local interface to which mirrored packets are sent. An analyzer can have output to either an interface or a VLAN, not both.

Output VLAN

Specifies a VLAN to which mirrored packets are sent. An analyzer can have output to either an interface or a VLAN, not both.

Mirror ratio

Displays the ratio of packets to be mirrored, between 1 and 2047 where 1 sends copies of all packets and 2047 sends copies of 1 out of every 2047 packets.

Loss priority

Displays the loss priority of mirrored packets. By default, loss priority is set to low, with mirrored traffic dropped in preference for regular traffic when capacity is exceeded. For analyzers with output to a VLAN, set the loss priority to high.

Egress monitored interfaces

Displays interfaces for which traffic exiting the interfaces is mirrored.

Ingress monitored interfaces

Displays interfaces for which traffic entering the interfaces is mirrored.

Ingress monitored VLANs

Displays VLANs for which traffic entering the VLAN is mirrored.
