Router(config)# policy-map pol1 Router(config-pmap)# class class-default Router(config-pmap-c)# bandwidth per 70 Router(config-pmap-c)# random-detect Router(config-pmap-c)# random-detect ecn Requires other bits in the network to be ECN aware, but if they are, good stuff. --
+1 There is no excuse these days for stuff not to be ECN aware. That GREATLY mitigates things as it makes hosts aware pretty much immediately that there is congestion and they don't have to wait for a lost packet to time out. I brought it up to a Brocade engineer once asking for the option to set ECN rather than drop the packet and he said "nobody uses it". I told him nobody uses it because you don't have the feature available. How can anyone use it if you don't have the feature?
