Swich 5700-Iscsi Jumbo Frame
Hi,
I need to configure JumboFrame on Switch 5700 with NettAPP eSeries 2862.
Should I activate on the jumboframe vlan because I noting see to Jumboframe
and should I activate it on the port
interface Ten-GigabitEthernet1/0/32
description ES2800
port access vlan X
jumboframe enable 9000
Because ISCSI don't work.
Is there another place to configure the jumboframe ont the switch ?
And is there a doc comware explain to configure jumboframe
Thanks,

Re: Swich 5700-Iscsi Jumbo Frame
Hello!
5700 has jumbo frames enabled by default and are 10000 bytes. They are enabled per physical port with command 'jumboframe enable [value]' if you need to change it to something else than 10000 bytes. With 'undo jumboframe enable' you can disable them. In general use 'display interface <interface_number>' command to check if jumbos are enabled and allowed size. Example:
Ten-GigabitEthernet1/0/1

If you see similar output on all your storage-related ports and your iSCSI still doesn't work inside one single VLAN, there must be something else to look for.
Hope this helps!
