you want the switch to accept inbound jumbo traffic. For operation with
GVRP enabled, refer to the GVRP topic under
“Operating Rules”, above.
2. Ensure that the ports through which you want the switch to receive jumbo
packets are operating at least at gigabit speed. (Check the Mode field in
the output for the show interfaces brief < port-list > command.)
