a fix to this could be adding
policy-map type network-qos jumbo-nq-8e-policy
class type network-qos c-nq-8e
congestion-control tail-drop
mtu 9000
system qos
service-policy type network-qos jumbo-nq-8e-policy
to verify whether the fex now passes jumbos, attach to the fex and observe whether TX/RX_PKT_{largesize} counters increment
e.g.,
fex# show platform software woodside rmon 0 hi7
| TX_PKT_2048 | 100|
| TX_PKT_4096 | 100|
