Cisco UCS FI and 5548 MTU

We have a Cisco UCS setup with a pair of FI's and a pair of 5548.

MTU is set to 9000 on FI's by using QoS

and also followed the below commands to set the jumboframe on 5548's:

switch(config)#policy-map type network-qos jumbo

switch(config-pmap-nq)#class type network-qos class-default

switch(config-pmap-c-nq)#mtu 9216

switch(config-pmap-c-nq)#exit

switch(config)#system qos

switch(config-sys-qos)#service-policy type network-qos jumbo

After all this, I used sh queuing interface eth 1/17 to veirfy and I do get the following which confirms the MTU = 9216

RX Queuing

qos-group 0

q-size: 469760, q-size-40g: 0, HW MTU: 9216 (9216 configured)

​

Here's the question:

When I issue the command to check on the port-channel MTU size, I still see 1500 on the port-channel,

sh interface port-channel 101

port-channel101 is up

vPC Status: Up, vPC number: 101

Hardware: Port-Channel, address: 0005.73f2.eda8 (bia 0005.73f2.eda8)

Description: To FI-A

MTU 1500 bytes, BW 40000000 Kbit,, BW 40000000 Kbit, DLY 10 usec

Why is it still showing 1500? I thought the MTU setting should be global? Thanks!!
