Nexus Fe2 Card shared mode

[Steev112]

Hi All,

i have two nexus 7k with two cards N7K-F248XP-25E and one card M2 for OTV, and five N7K-C7009-FAB-2 in each chassis, my questions are:

1. this module N7K-F248XP-25E, i read this module has two mode shared and dedicated, if i use it dedicated for all the interfaces each module will provide us 480? or what is the maximum i will get?

Thanks

Where did you read it supported shared mode as my understanding is that it is only dedicated on that module.

Dedicated doesn't mean you won't get oversubscription because that depends on the amount of fabric modules you have in the chassis.

However you have 5 fabric-2 modules which provides up to 550Gbps per slot and the F2 module has a potential throughput of 480Gbps ie. 48 x 10Gbps so there would be no oversubscription in your case.

You should be able to see if the module supports shared mode by doing a "sh interface capabilities" and there will be a "Rate mode" line which will say either "dedicated" or "dedicated/shared".

Hi Steven

Yes there are 12 port groups on this module and each port group gets 40Gbps to the switch fabric.

As you have 550Gbps per slot available each port group will get the full 40Gbps.
