Disable ISL QOS

  • 1.  Disable ISL QOS

    Posted 12-08-2014 01:30 AM

    We don't use QOS zones and thus we're looking at disabling QOS on our ISL's.

     

    We currently have 3 ISL's. 2 ISLs have 2 connections (16Gbps total bandwidth) and 1 has 4 (32 Gbps total).

     

    Given we have 3 links and as this process is disruptive are we able to just run the portcfgqos --disable slot/port on each port and just wait for them to come back up without QOS enabled and then move onto the next port?

     

    A further question:

     

    If we want to disable an ISL, is there a preferred method or do we just pull the cable's form the ports?

    Hi,

     

     

    In response to your query:

     

    I would disable the ISL/TRUNK and then disable QoS. Afterwards enable it back and go for the next ISL/TRUNK.

    (I would modify the Principal ISL the last one, just to aboid unnecessary Build Fabrics, but no problem if you do it in a different order)

     

    Better than pulling cables, to temporary disable an ISL, use the command portdisable.

     

    Rgds,

    Felipon
