If I remember correctly, whenever an Etherchannel changes from two or more members to one member (or vice versa), an STP reconvergence is triggered. Assuming that to be correct, you'll still have an STP blip during a link/card failure. :( pt _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
