I hope I've helped.
I have scenario where in 2 N5k's in a pair are connected to vss (upsttream)in a single port channel. For testing the failover and end to end connnectivity, I tried to ping from a fex on N5k to a switch connected to VSS s/w. In the mean while I rebooted the primary but the ping didn't drop but as soon as the primary N5K was up I could see 6 to 7 ping drops and againn it started pininng continously..
Can u guyz help me with it.
