On a specific VLAN - used for storage - I'd like to enable jumbo frames (9000 bytes).
If I check the manual, it states than it's possible to do this on a VLAN (command VLAN MTU 9000), but on the other hand, Jumbo frames need to be configured via SYSTEM MTU JUMBO 9000, affecting all gigabit-ports.
Is it possible to use jumbo frames for a single VLAN, or what does it do on the VLANs with an MTU of 1500 when the system mtu jumbo-parameter is set ? And can this be forwarded to another stack as well ?
I have some difficulties in the traffic between some stacks, which contain also C3750-switches with fast-ethernet ports, and I think it's because of the jumbo frames-setting in the stack in the server-room. Also the connection to other switches (2924 / 2950) seem to have some problems, and also here I'm thinking the trunking is having problems since the configuration of jumbo-frames...
