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:
- Login to your switch.
- After login type: <switch># config
- You will enter the config mode, type: <switch>(config)# show vlans to show the VLAN configuration.
- To enable Jumbo Frames on the VLAN type: <switch>(config)# vlan <ID#> jumbo
- 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.
- Save your changes:<switch>(config)# write memory
- Logout from the switch.
Tested on a HP ProCurve 2900-24G switch.
Cheers!
