    Hi,

     

    Is there any documentation anywhere to show the configuration of CoS/QoS on an SRX300/340?

     

    Is it possibly as simple as the following:

     

    Configure the CoS and assign to an interface (as I have on the MX240s)?

     

    Or, does the CoS have to be assigned to a zone? I guess this is where the difference may well be.

    Ideally the cos you applied on MX can be applied to SRX as they both run Junos. There may be few features that don’t support. One more thing, SRX branch platforms do software based CoS .

    CoS is not connected to zone/security as it has no relation with flow processing on SRX.

    Hi Suraj,

     

    Thanks....

     

    The only issue there appears to be is the following:

     

    commit check
    [edit class-of-service interfaces]
    'ge-0/0/15'
    'per-unit-scheduler', 'hierarchical-scheduler', or 'shared-scheduler' for this interface is required for scheduler map on interface unit
    error: configuration check-out failed: (statements constraint check failed)

     

    I am guessing that this failed because I am applying the scheduler map to a subinterface and there is an extra requirement, as stated in the failure message..... I will have a look for what is required, but in the meantime, any ideas please?

     

    Thanks

    #set interfaces ge-0/0/15 per-unit-scheduler
    #commit

    Please note that applying this will flap the interface.
