Port Channel Routing issue

cbregeripr

Level 1

I am an issue with a LACP port Channel on 6509(Sup720) and a Nexus 5020.  This is a L2 Port Channel with multiple Vlans.  We have several VMs running on a UCS system with 65248s connected to the Nexus.  The 6509 is the L3 gateway for the VLANS which house the VMs.  We seem to have an issue connecting some hosts on seperate L3 Vlans which have traverse the Port Channel and route across the 6509.  When I shut down one of the 2 links of the port channel all hosts can see one another.  When both ports are enabled some hosts are not able to see all other hosts on other Vlans.  Below is the Port Channel Config for both Switches.

Do you have the same issue if you make one side of the portchannel active (5k) and the other side passive (6500)?

I haven't tried this.  How would this affect traffic?
