I have a Nortel Route Switch 8661 and trying to connect to a Catalyst 3750 24 Gig ports.
Have tryied several of the 24 RJ-45 ports and the link doesn't come up.
If I connect a PC to the 3750 then it works. I'm trying to establish a 100Mb link between these two.
Have someone seen this before. Thanks?
3750 does MDIX so you can use straight-thru cables when connecting to switches together but there is one requirement:
The speed/duplex on the port should be left auto/auto because if you hardcode to a fix speed then MDIX might mis-behave.
Not sure what your settings are on the Cisco switch?
