GBIC's showing "inactive" on dual Supervisor 6E's

Unanswered Question
Feb 24th, 2009

To All,

I have a customer with a C4510R-E with dual supervisor 6e's running 12.2(46)SG enterprise services. The customer's expectation was that all four GBIC ports may be utilized in various combinations (10 Gig or 1 Gig), but we have found that only port one on each supervisor is active (port 5/1 and port 6/1 currently utilizing 10 gig GBIC's), while port 5/2 and port 6/2 are inactive with GBIC's inserted.

I found the link below which does not mention the redundancy factor (dual supervisors) that I stated above, but it does say the 4510R chassis is limited (two 10 gig links or four 1 gig links).

Although we have the dual supervisor's, are we still limited by only being allowed to turn up two 10 gig links or four 1 gig links?

Thank You

I have this problem too.

Did you reboot the active sup after using the following command:

hw-mod uplink mode shared-backplane

I tried the other hw-mod commands, but not the shared-backplane option. I'll try that and reboot the supervisor.

Thanks for the response.
