Where is stored MTU configuration on switch

[gbusson]

We changed MTU size on 2950 and 3750 switch.

We can see MTU parameter in startup-config file for 2950 but we don't see anything in startup config file for 3750.

Where is stored this parameter for 3750 ?

Hi,

When you change the MTU size, you must reset the 3750 switch before the new configuration takes effect. Reset the switch after the changes and it should show you in there.

Hi,

we have reset the switch. Show system MTU is ok but nothing about MTU in startup-config

[amit-singh]

It doesnot show you that in startup-config on 3750. You can check it only using " show system mtu " command.

If i understand, if my switch has a crash and i need to change with a new one, i can get configuration from ciscoworks but i have to set manually system mtu in the new switch
