Interoperability between 6500 and 4500

Morning all,

I am having problem with interconnection of 6509 and 4506. Network just crash once I put a connection between them with an etherchannel.

Any document available on CCO for the interoperability between these two switches?

Thanks

Re: Interoperability between 6500 and 4500

The problem is that there are tons of docs on both systems. No kidding, this should work straightforward.

A while ago I had a site where the 6509 "froze" when I connected an uplink from a 3550. Turned out that the 6500 was running Rapid STP instead of the default PVST+. The solution was to block stp bpdu's on the link using the interface command:

spannning-tree bpdufilter enable

You might have somthing similar at hand.

Regards,

Leo
