Max MTU just states how large the L2MTU & MTU for that interface can be. It is a read-only parameter.
There should be no problem leaving the L2MTU the default 1600, or even raising it to 9500. The L2MTU only matters if you utilize tunneling. Layer 3 traffic will still utilize 1500 byte packets unless you change the MTU= parameter. I run MPLS and Q-in-Q across my network. I always raise the L2MTU to its max value so that I don't not have to incur an interface reset if I need to raise it in production. -- Blake Covarrubias On Sep 24, 2011, at 8:45 AM, Chupaka wrote: > Is L2MTU changeable?..
