This is wild stuff, so I thought I'd run it by GroupStudy to see if anyone had seen this before or knew what caused it.
We're currently migrating connections from a 5513+RSM to a new 6509+Sup2/MSFC2. There were three ethernet connections, that upon being moved from the 5500 to the 6500, starting showing input errors and CRC errors. When these connections were moved, the port on the 6500 was configured identically to the same port on the 5500 as far as speed, duplex, VLAN assignment, and spanning tree settings. These same devices (same patch cables and all) created no errors on the 5500 whatsoever. Here's the kicker: When we went back and changed the port speed/duplex to "auto" on the 6500, it negociated the same speed/duplex settings we had forced, but now there were no more errors. (i.e. a server set for 100-Full, that was plugged into a switchport on the 5500 forced to 100-Full was fine, but plugged into a port on the 6500 forced to 100-Full caused errors, and plugged into the exact same 6500 port set for "auto" speed/duplex had no errors.) Any ideas on why letting the switch detect settings caused no errors while forcing it to those same settings causes errors? Thanks, Mike W.
