CISCO 4510R-E

Can you do a show module and post here?

when I put a 10GB SFP into port 5 or 7 and I check the command SHOW INTERFACE STATUS, I can see the SFP´s.
But the Status of the interface is always INACTIVE

I have read an article, just the first 2 ports are active.

But how to activate the other 10GB ports ?

Thanks.

Please refer to the following links - specifically table 2 here...

You can't use all 8 10G ports on the supervisor in dual-supervisor configurations.  You can only use 4x 10G uplinks on each supervisor.  If you remove the standby supervisor you can use all 8 10G ports.

I know that answers why you can't use all 8 ports, but it implies you can use 4 ports per supervisor, however you can only use 2.  Therefore the limitation may be software (according to the first link 4 port enablement in dual-supervisor mode is on the software roadmap), so it may be that you need to upgrade IOS to enable ports 3-4.

Going back to your comment...

when I put a 10GB SFP into port 5 or 7 and I check the command SHOW INTERFACE STATUS, I can see the SFP´s.
But the Status of the interface is always INACTIVE

...that makes sense based on the links.

my IOS is version 15, the latest.
But I have to check if the ports 3-4 are coming up.
I just tested the ports 7-8.

But why just 4 of 8 Ports are usable ?
This makes no sense for me.

ok thanks so far...I will check my 4 ports

Thanks, works with 4 ports.
