ifIndex
1.3.6.1.2.1.2.2.1.1

Read only

A unique value for each interface.
The values range between 1 and the value of ifNumber. The value for each
interface must remain constant, at least from one re-initialization of the
entity's network management system to the next re-initialization.
For Network Interface, the number starts from 805306369 and increments
with the interface count. For FC ports, the number starts from 1073741824
and increments with the existing FC ports. Similarly the index value range for
the interfaces are as follows:

For GbE port the number starts from 268435456

For Ten GbE (FCoE ports) the number starts from 402653184

For FCIP Tunnel the number starts from 536870912

For xFCIP Tunnel the number starts from 1342177280

For Port channel the number starts from 671088640

For VLAN the number starts from 1207959552

ifMtu
1.3.6.1.2.1.2.2.1.4

Read only

The size of the largest datagram that can be sent or received on the
interface, specified in octets.
For interfaces that are used to transmit network datagrams, the value is the
size of the largest network datagram that can be sent on the interface (these
values are different for Fabric OS v4.x).

eth0 returns 1500

lo returns 16436

fc0 returns 2024

FCIP GbE returns 1500

sit0 returns 1480

port0 returns 2112
