First off, this could just be my misunderstanding of SSO and redundancy, and I may be trying to fix something that is not broken. I have looked thru the documentation, and searched the forums, but am still a little confused.
We replaced an aging Cat 4k with a 6506 with redundant Sup720's in our data center. Everything seems to be running perfectly, but there is an odd (to me) thing going on. The Sup720 in slot 5 is listed as the active sup, but when looking at the counters, the sup in slot 6 seems to be doing all the heavy lifting. It was my understanding that the active sup would be handling all packet transfers, while the standby was listening to the "heartbeat" waiting to jump in.
I have attached a pdf file the counters, and redundancy info. If I have noting to worry about, great. It just seems odd to me.
There isn't a problem I don't believe , slot 6 is standby but even though slot 6 is the standby supervisor the actual uplink ports on both supervisors are active and usuable . If you look at your config you will probably see that slot 6 link configured and it just happens to handling more traffic that the slot 5 uplink, nothing inherently wrong with that.
