column

bytes Unsigned32
The size of the largest packet which can be sent/received
on the Ethernet physical interface, specified in octets. For
interfaces that are used for transmitting network datagrams,
this is the size of the largest network datagram that can be
sent on the interface.
Setting tnPortEtherMTU to a value of zero (0), causes the agent
to recalculate the default MTU size which can vary based on the
current setting of tnPortMode and tnPortEncapType variables.
Some typical default values are:
1514 with mode access and encap-type null
1518 with mode access and encap-type dot1q
1518 with mode access and encap-type mpls
9198 with mode network
