I have a couple of questions concerning L2 etherchannels. Can you please help?
1- Is there a way to increase drastically the STP port cost of an unbundled etherchannel interface, forcing the traffic to be switched to another interface?
As an example, imagine you have a direct etherchannel link at 2x1Gbps (STP cost 3) and one of the links fails (STP cost increases to 4). I would like to increase this cost to 10 when the failure happens...is this possible?
2- Is there some sort of dampening system (BGP-like) for etherchannels?
I will use PAgP since I'm only dealing with cisco boxes.
It seems to me strange that no one ever requested the feature 1) to Cisco...imagine you have 1,2 Gbps of traffic running on a 2x1Gbps etherchannel directly between 2 switches. Imagine you also have an alternate path also with 2x1Gbps etherchannels but with an extra hop in between. It seems natural to me that you would like your traffic to cross the link with more hops but with the required bandwidth then having 200Mbps of traffic dropped on the etherchannel with the failure....
