I have two cisco 6513 sup 2T configured as VSS and I need to connect a UCS b-series to this VSS using two physically ports configured as port-channel
i tried all modes of the port channel, no mode made the portchannel up except "mode passive" but after the portchannel is up on passive mode there is one physical port was flapping.
how can I solve this problem, please advice ?
thanks in advance
Go to Solution.
Port Channel passive mode is correct,
but you must use one Port Channel for each FI
If this is correct check your cabling connection
