egress queue stats and logical interfaces

  • 1.  egress queue stats and logical interfaces

    Posted 10-12-2017 18:03

    Hi everyone,

     

    Please consider the following example:

     

    On SRX 650, we have following logical interfaces :

     

    ge-0/0/1 unit family inet   1.1.1.1

    ge-0/0/2 unit family inet  2.2.2.2

     

    so when I do show interface queue ge-0/0/1, is it showing the totals egress stats of all logical interfaces?

     

    My second question is there anyway we can have seperate  egress STATS for each logical interface? 

     

    Will enabling per unit scheduler i.e set interface ge0/0/1 per unit scheduler do the trick?

     

    Thanks,

    Without per-unit-scheduler, queue statistics are available for physical interface only

     

    lab@SRX1-A# show interfaces fe-0/0/1
    vlan-tagging;
    unit 10 {
        vlan-id 10;
        family inet;
    }
    unit 20 {
        vlan-id 20;
        family inet;
    }
    
    lab@SRX1-A# run show interfaces queue fe-0/0/1 egress
    Physical interface: fe-0/0/1, Enabled, Physical link is Down
      Interface index: 135, SNMP ifIndex: 503

        Packets              :                     0                     0 pps
        Bytes                :                     0                     0 bps

        Bytes                :                     0                     0 bps
        Tail-dropped packets :                     0                     0 pps
        RED-dropped packets  :                     0                     0 pps
    ---cut

        Output packets: 0
    
    lab@SRX1-A# run show interfaces queue fe-0/0/1.20 egress

        Output packets: 0

    With per-unit-sceduler, queue statistics are available for physical interface and logical units

     

    lab@SRX1-A# show interfaces fe-0/0/1
    per-unit-scheduler;
    vlan-tagging;
    unit 10 {
        vlan-id 10;
        family inet;
    }
    unit 20 {
        vlan-id 20;
        family inet;
    }
    
    lab@SRX1-A# run show interfaces queue fe-0/0/1 egress

        Bytes                :                     0                     0 bps
