I feel I have configured this correctly but the interfaces are still showing 1500 MTU. First off, I know that the switch has a default system MTU of 9216. I did set that manually at first, but realized it wasn't necessary so I removed the configuration. I configured the following policy map:
policy-map type network-qos PM-JUMBO
class type network-qos class-default
service-policy type network-qos PM-JUMBO
I then see the system inform that this policy is now active. But checking the interface I still see it at 1500. If I manually set the MTU to 9216 it does reflect the change.
Not sure where I could be going wrong with this. It would appear that I have to set this manually for all ports which doesn't seem right to me.
Also, I would like the same to be configured for the FEX I have hanging off of these 9Ks but I can't seem to find a global config option for this.
Just came across this myself. The explanation is likely specific to the 93180YC-EX line, as this switch is essentially a rebranded Nexus 5672 which itself is really a Nexus 6k
