Overview
1. Determine the VLAN membership of the ports or trunks through which
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.)
3. Use the jumbo command to enable jumbo packets on one or more VLANs
statically configured in the switch. (All ports belonging to a jumbo-
enabled VLAN can receive jumbo packets.
4. Execute write memory to save your configuration changes to the startup-
config file.
