How to enable Jumbo Frames on a HP ProCurve Switch.

When configuring an iSCSI network, don’t forget to enable the Jumbo Frames on you physical switches. Follow these steps to enable the Jumbo Frames on a specific VLAN on a HP ProCurve switch:

1. Login to your switch.
2. After login type: <switch># config
3. You will enter the config mode, type: <switch>(config)# show vlans to show the VLAN configuration.
4. To enable Jumbo Frames on the VLAN type: <switch>(config)# vlan <ID#> jumbo
5. Check if the setting applied successfully by typing: <switch>(config)# show vlans again. The Jumbo column for the specific VLAN in the output should change to Yes.
6. Save your changes:<switch>(config)# write memory
7. Logout from the switch.

Tested on a HP ProCurve 2900-24G switch.

Cheers!
