Jumbo MTU on Nexus 2232 FEX

Adrian Lazar

Hi,

 

This is related to bug CSCum09831  - jumbo MTU does not work on 2232 FEXes unless it is configured globally. Currently we have several qos groups with jumbo MTU enabled on only one of them and this setup works fine on 2148 FEXes but not on the 2232.

Now I want to enable Jumbo MTU on all qos groups but I'm not sure that this will solve the problem, any suggestions would be highly appreciated.

 

Thanks,

Adrian

Hi Adrian,

 

I checked the BUG and for 22XX Fex the Jumbo Frame configuration has to be done globally. This is part of the design for these series of Fex.

So i would suggest to enable Jumbo frames globally and see if the issue gets resolved. Else you can reach out to me i will be more than happy to assist.

Regards,

Seemab

Hi Seemab,

 

When you say to enable jumbo frames globally you mean to enable them on every qos-group?

 

thanks,

Adrian
