enable MTU for vlan on PowerConnect 6248
Hi
For some strange reason I cannot enable MTU for vlans. I get below error:
console(config)#interface vlan 1000
console(config-if-vlan1000)#ip mtu 8000
Could not get the internal interface number associated with the Unit-Slot-Port.
Any idea why?
!System Description "PowerConnect 6248, 3.3.11.2, VxWorks 6.5"
!System Software Version 3.3.11.2
No Events found!

There was a thread already regarding this question :

You can try enabling the jumbo frames globaly or the on each port not per vlan.

What is the reason that I can't enable jumbo frame per vlan?
If I can't enable jumbo frame per vlan, what is the command "ip mtu" for?

Maybe there was some limitations on old f/w versions,try updating to latest f/w
dell.com/support/home/us/en/19/Drivers/DriversDetails?driverId=TWGNF&fileId=3383798720&osCode=NAA&productCode=powerconnect-6224&languageCode=EN&categoryId=NI
in release notes I can see some changes regarding mtu.. and here I think is the answer :
ip mtu Command Changed (Maximum Value Increased)
The maximum value for the ip mtu command has increased from 1500 to 9202. If not configured, the IP
MTU tracks the interface MTU.
so go for an update, probably that should help..
