Hi Karthik,


If you don't need QOS, then don't configure it specially since you are not running VoIP.

Impossible to say without knowing the company policy on bandwidth usage, security etc. They may be there for a very good reason and then again they may be just default config. Just because the 3560 is acting as a L2 switch does not mean the QOS commands are not being used.

Hi,


I agree with Jon here, whether you have VoIP or not does not necessarily mean that you don't require QoS.  QoS maybe implemented specifically for egress scheduling for other protocols other than Voice.  Therefore QoS may have simply been configured due to your own company policy/requirements or has been configured without any specific reason.  Unfortunately you will only be able identify the real reason from discussing this with your peers.

Allan.
