Jumbo MTU on Nexus 2232 FEX
Hi,   This is related to bug <key>CSCum09831</key>  - 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
