We're teaming between 2 4500 switches (it works as active-passive) that we deploy as backbone switches. we are teaming 2 ports from 4500 to edge switches are active while some VOIPs are done but some are not. But when we command shutdown one of the teaming ports, VOIP phones are all working. how could we tshoot?
if you aggregating on the edge ports then the device attached to them should also be able to support that aggregation?
