Re: mls Qos

Hello guys,
                  Also remember before using this command *(mls qos)* to
check if there is any *ether-channel *configured between switches.
if yes, check the platform & line card HW capabilities in QOS ( queuing 2q8t
or 1q4t...ect)
cause if they doesn't match , the ether-channel will be broken, even if u
didn't configure any QOS parameters on it.
