  • 1.  vMX COS issue : Egress queue statistics are not applicable to this interface

    Posted 06-30-2023 21:45

    Hi guys,

    I am using running  JUNOS 18.2.R1.9

    For some reasons, it is not showing any queue stats:

    root> show interfaces queue ge-0/0/2  
    Egress queue statistics  are not applicable to this interface.

    CONFIG##

    root# show class-of-service | display set 
    set class-of-service classifiers dscp LEE forwarding-class CS1 loss-priority low code-points cs1

    Hi, 

    Enable flexible queuing mode on the chassis.

    [edit]
user@vmx#

    set chassis fpc 0 flexible-queuing-mode
