dear all,

i'm using 3750ME with IOS 12.2(25)EY and 12.2(44)SE acting as PE device.

on 3750ME ES port i'm configuring mpls connected to 7606 RSP 720 with IOS SRB1 as P device.

the problem is, on 3750ME even i've changed the system mtu jumbo to 1546 or 9000 it seems that the mtu value used by 3750ME is system mtu not the value of system mtu jumbo.

i've verified the value of system mtu jumbo using show system mtu and show interface.

any feedbacks are welcome.

Have you tried changing normal MTU? Not the Jumbo one?

yes i can change the system mtu to 1546, but this affect the fastethernet interface mtu to 1546, while my customer requirement is only use 1500 byte on access port.
