QFX - port mirror / capture to remote IP

  • 1.  QFX - port mirror / capture to remote IP

    Posted 02-13-2023 06:00

    I am trying to see if it's possible to use the analyzer to mirror an interface to a remote server so I can packet capture. Running 21.4R3-S2.3

    set forwarding-options analyzer test1 input ingress interface et-0/0/49.0
    set forwarding-options analyzer test1 input egress interface et-0/0/49.0
    set forwarding-options analyzer test1 output routing-instance mgmt_junos ip-address x.x.x.11

    > show forwarding-options analyzer         
      Analyzer name                    : test1
      Mirror rate                      : 1     
      Maximum packet length            : 0     
      State                            : down  
      Ingress monitored interfaces     : et-0/0/49.0
      Egress monitored interfaces      : et-0/0/49.0

    the ip is reachable in the management routing instance, but the state remains down. I don't see any erspan traffic on the remote host. I can't find much in the way of docs for this, is this possible?
