Set Jumbo Frames On A Nexus 3064

It is configured system wide to 9216 with the following commands:

1
2
3
4
5
6
7
policy-map type network-qos jumbo
class type network-qos class-default
mtu 9216
exit
exit
system qos
service-policy type network-qos jumbo

Verification is a bit odd, though. If you enter a standard show interface, it won’t show the correct value:

1
2
3
4
5
6
7
8
9
10
sw02# show int e1/1
Ethernet1/1 is down (SFP not inserted)
 Dedicated Interface
  Hardware: 100/1000/10000 Ethernet, address: 547f.ee52.9a08 (bia 547f.ee52.9a08
)
  MTU 1500 bytes, BW 10000000 Kbit, DLY 10 usec
  reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA
  Port mode is access
  Full-duplex, 10 Gb/s

Notice how it has MTU displayed as “1500 bytes”.

If, however, I use the show queuing command it displays correctly:

1
2
3
4
5
6
7
8

    qos-group 0
    HW MTU: 9216 (9216 configured)

        Mcast bytes dropped                     : 0
 
    Pkts dropped by RX thresholds               : 0
    Bytes dropped by RX thresholds              : 0

Notice it shows “HW MTU: 9216”.
