    Hello everyone,

    I am testing port mirroring on EX3400, but unable to get it to work, any help will be grateful.



    I have a VM connected onto ge-0/0/47 to perform pings to irb.10/Vlan 10 , 10.80.140.81/29 on the EX3400.

    I have the analyser configured as below on the EX3400.

    root@tsxvcwes02j34> ...arding-options analyzer | display set
    set forwarding-options analyzer analyzer1 input ingress interface ge-0/0/47.0
    set forwarding-options analyzer analyzer1 input egress interface ge-0/0/47.0
    set forwarding-options analyzer analyzer1 output interface ge-0/0/9.0

    root@tsxvcwes02j34> show configuration interfaces ge-0/0/9 | display set
    set interfaces ge-0/0/9 unit 0 family ethernet-switching interface-mode trunk
    set interfaces ge-0/0/9 unit 0 family ethernet-switching vlan members vl-99
    set interfaces ge-0/0/9 unit 0 family ethernet-switching vlan members remote-monitor
    set interfaces ge-0/0/9 unit 0 family ethernet-switching vlan members vl-10

    When I monitor traffic interface ge-0/0/9 size 9999, I should be getting mirrored icmp messages from ge-0/0/47 .. but I dont see them.

    root@tsxvcwes02j34> monitor traffic interface ge-0/0/9 size 9999
    verbose output suppressed, use <detail> or <extensive> for full protocol decode
    Address resolution is ON. Use <no-resolve> to avoid any reverse lookup delay.
    Address resolution timeout is 4s.
    Listening on ge-0/0/9, capture size 9999 bytes
