Jumbo frames dropped on Nexus 7K

[support1@lima.co.uk]

Software
BIOS: version 3.1.0
kickstart: version 7.3(3)D1(1)
system: version 7.3(3)D1(1)

I have a DC to DC link and jumbo frames are being dropped every third packet.

I cannot see the "show policy-map interface control plane" command is this because it is not on version 7.3.3?

This link is only used from replication traffic so I would like all traffic on this link to have priority. Can I set a policy map and class map to treat all traffic as critical?

When attempting to define the class map I have protocols which seem to be missing also?

XXXXXXXXXXXXXX(config-cmap-qos)# match protocol ?
arp IP ARP
bridging Bridging
cdp Cisco Discovery Protocol
clns ISO CLNS
clns_es ISO CLNS End System
clns_is ISO CLNS Intermediate System
dhcp Dynamic Host Configuration
iscsi Iscsi
isis Intermediate System Intermediate System Protocol
ldp Label Distribution Protocol
netbios NetBIOS

XXXXXXXX(config-cmap-qos)# match protocol

Hi support1@lima.co.uk 

"show policy-map interface control plane" - this command is to see the CoPP (Control Plane Policing) - which affects only traffic sent to CPU, so control plane traffic only. 

You can have a look here at an example on how to configure QoS on N7K:
