Hi,
I am converting 2 6500 chassis to VSS, currently they are configured as primary & backup. Downstream switch have 4 uplinks, 2 to each chassis with port channels. After I convert to VSS I will have all 4 ports connecting to downstream switch in a port channel, can I keep 2 separate port channels on downstream switch or will it cause issues ?
thanks

Hi,
In order for the links to fail over correctly, you need to put all 4 physical links in one Portchannel.
Right now, you have 2 different Portchannels because the switches are standalone. Once you convert to VSS, both switches look like one switch (logically)

Hi Hazrat,
I agree with Reza. By the way what is at your mind in keeping 2 seperate port-channels to one device?(please note after VSS logically it is one switch). One of the Port-channel will not be used at all since spanning tree will block it. So as Reza said bundle them in all one.
Thanks,
