I suspect some issues with faulty QoS settings on a 3750 stack running in a 24x7 environment. The 3750 mainly routes between vlans on a lan segment. Since it is a lan device (not terminating any wan links) i want to globally disable QoS (
no mls qos), I prefer to run QoS only on wan links.
I will be doing this on a off-peak moment but want to find out what impact on the trunks and access links this will cause? Will it cause a disruption? And does it clear any custom QoS settings or does these remain but ignored? Cant seem to find a conclusive answer..
