[j-nsp] Setting MTU

[chrisccnpspam2 at gmail.com]

You have to set the mtu at the physical interface level. You must also account for the L2 overhead tho. Meaning if you want 9000 byte mtu for ip you need to set the physical ethernet interface to 9014.  If you set the physical to a higher parameter the family will inherit the MTU as well. Meaning you wouldn't have to code 9000 if that is the mtu you wanted.

MX 480
10.0R2.10

I am trying to change the MTU on my MX 10g interface, but every time I do a commit check I get this:

Family MTU is too large relative to device MTU
error: configuration check-out failed

It will let me set the MTU under interface  family inet, mpls, but unable to commit it.
Any help would be much appreciated

Thanks,
Brian
