Cisco Nexus 3548 MTU issue

[lmqtechnology]

I have two cisco Nexus3500 C3548P-10GX Chassis connected to one another via L3 port-channel. MTU on the system and interface are both set to 9000, however I am unable to ping over link more that 1478 bytes?

But mtu with qos policy set for l2, you have l3 PO ?

May be this issue

Anyway glad you solve issue.

Understood, but that’s how TAC resolved. Thanks for your help

Hi, do you have some more detail available on what this QoS policy should look like to the the proper MTU? Thanks a lot in advance.
