Specific Supervisor ports not working on 4507R+E

[stephendrkw]

I bundled 8 x 1GB ports in a 2 Port channels on my dual Supervisor Active/Redundant scenario 4507R+E (4 in each Sup)

I was unable to use Te3/5, 3/6, Te4/5, Te4/6 they were inactive, in the end I had to use the below ports.

ONLY all these 4 above ports were in D state on Po1 and Po2

I put an a working SPF in these 4 ports and could not see a red glow unlike the others (not a good idea to do this protect your eyes!) to me this means the port is dead, though I ran diagnostic tests and these ports passed passed successfully. I swapped 1GB SPF's from the working ports to these non-working ports, still nothing, no light at all and also working cables from other ports

I'm confused......are these specific 4 ports used for something else? Like shared-backplane, still nothing adds up for me why these did not become P

Number of channel-groups in use: 2
Number of aggregators:           2

Hello,

are your supervisors WS-X45-SUP6L-E by any chance ? If they are, the following applies:

--> When Sup6LE supervisor is deployed in redundant mode (dual-sup) then system will allow only Port-group 1 to use, it can be in 1G or in 10G mode. Port-group 2 remains inactive and this supervisor module does not support shared-backplane (oversubscription) capability.<--

Hi,

The are...........I guess then this statement applies

#sh mod 3
Mod Ports Card Type                              Model              Serial No.
---+-----+--------------------------------------+------------------+-----------
 3     8  Sup 8-E 10GE (SFP+), 1000BaseX (SFP)   WS-X45-SUP8-E

Hello,

I found this out:

If you use 2 sups (WS-X45-SUP8-E) with redundancy SSO, you can use 4 ports (10G) from each sup.

Thanks, this would explain.
