Verifying Input and Output for Port Mirroring Analyzers on EX Series Switches

Purpose

Verify that an analyzer has been created on the switch and has the appropriate output interfaces, and appropriate output interface.

Action

You can verify the port mirror analyzer is configured as expected using the show analyzer command.

[edit]
user@switch> show analyzer 
Analyzer name                  : employee-monitor
  Output VLAN                  : remote-analyzer
  Mirror ratio                 : 1
  Loss priority                : High  
  Ingress monitored interfaces : ge-0/0/0.0
  Ingress monitored interfaces : ge-0/0/1.0

You can view all of the port mirror analyzers configured on the switch, including any that are disabled, using the show ethernet-switching-options command in configuration mode.

user@switch# show ethernet-switching-options 
inactive: analyzer employee-web-monitor {
    loss-priority high;
    output {

analyzer employee-monitor {
    loss-priority high;
    input {
        ingress {
            interface ge-0/0/0.0;
            interface ge-0/0/1.0;
        }
    }
    output {
        vlan {
            remote-analyzer;
        }
    }
}

Meaning

This output shows that the employee-monitor analyzer has a ratio of 1 (mirroring every packet, the default), a loss priority of high (set this option to high whenever the analyzer output is to a VLAN), is mirroring the traffic entering ge-0/0/0 and ge-0/0/1, and sending the mirrored traffic to the analyzer called remote-analyzer.
