I have a lucent p220 cayjun switch and two cisco catalyst switches. the cisco switches talk to each other over a gigabit trunk. I'm tryin to get the two catalyst switches to be able to trunk to that cajun using its g1 port
Not sure what Cat switches you have, but the cajun switch must use the same trunking encapsulation. Older catalyst switches use ISL trunking which only work with Cisco switches. Make the port between the lucent and cisco dot1q encapsulation on the cisco trunk port. Also turn on debugging on the cisco and see what messages are generated.
