I have a 2 Cat 4510-E each of them has 2 supervisor Engines. They are linked thru 20Gig etherchannel link. Sw1-Te5/1 to Sw2-Te5/1 and Sw1-Te6/1 to Sw2-Te6/1. I convert SW2-Te5/2 into TwinGig and insert 2 SFPs. Then I use the command hw-module module 5 port-group 2 select gigabitethernet to switch from TenGig to Gig. But the port does not come up. When I issue the command Show hw-module module 5 port-group I can see that the port-group 2 is inactive. Would you please give me a clue on how to activate the port?
Your help is greatly appreciated
