HI
I want to adjust the mtu value on cisco nexus 3064 switch
For the device, the mtu value can be adjusted in the individual interface for the L3 port, but it must be adjusted through the qos setting (global setting) for the L2 port. see cisco guide

n3k-sw# config t
n3k-sw(config)# policy-map type network-qos ?
WORD Policy-map name (Max Size 40)
n3k-sw(config)# policy-map type network-qos JumboFrames
n3k-sw(config-pmap-nq)# class type network-qos class-default
n3k-sw(config-pmap-nq-c)# mtu 9216
n3k-sw(config-pmap-nq-c)# system qos
n3k-sw(config-sys-qos)# service-policy type network-qos ?
WORD Policy-map name (Max Size 40)
n3k-sw(config-sys-qos)# service-policy type network-qos class-default
n3k-sw(config-sys-qos)# show policy-map type network-qos
Type network-qos policy-maps
What I am curious about here is, if you set "n3k-sw(config-pmap-nq-c)# mtu 9216" through global configuration with qos,
Does it affect some opposing equipment using 1500 mtu value?
What is the benefit of creating an interface vlan and setting it to mtu 9216 ?
