Using the resources in this thread, I've tracked down a couple points of
interest.

ENBs running [4013, 4539, or 4573]  return a full packet (ICMP+headers) of
MTU 1900. (Payload 1900-28=1872) This is on either bearer or management
VLANs.

EPC running 729, however, returns only 1496 (1468+headers). This is on
several PDNs, management, and bearer.

In all cases (Mikrotik routers, Netonix switches in some places) MTU size
is set to 1900 or higher.

On the EPC, netstat does not appear to show interface info (no -i flag), so
I can't tell what the MTU is purported to be.

Has anyone had success verifying and/or changing the EPC's MTU(s)?
