    Hello team,
    At one of our client side ,we are getting tx (oversize) error on AP ports. I have changed the MTU size to 9198 on access switch interface and on core switch i have done ip MTU 9198 on interface vlan .But still after sometime I am getting same error on every AP switch ports.
    I will be very grateful if someone can help me with this issue.

    Thanks,

    In order to assure jumbo frame can be used you need to implement it end-to-end including controller/gateway, uplink ports etc. Also firewall on the controller should accept jumbo frames.

    Hello Shivam,

    have you tried to play with the MTU on the AP side (if the problem still persist of course)?
