◦ For FEXs that are connected to M-series uplinks, the queuing structure is different on FEX host
interfaces and FEX fabric interfaces. The M series queuing policies must be consistent with the
FEX queuing policies.
◦ DSCP-based queuing is not supported on M1 FEX fabric uplinks.
◦ You cannot modify the CoS 0-4 mappings in the default queue on M1 FEX fabric uplinks.
◦ FEX queue MTU configurations are derived from type network-QoS policy-map templates. MTU
changes are applied on cloned network-QoS policy maps. The MTU that is configured on a FEX
port must match the MTU in the network-QoS policy map so that the FEX MTU can be applied
to the FEX host interfaces. For more information, see the Cisco Nexus 7000 Series NX-OS Quality
of Service Configuration Guide.
