cnt2XIfMtu
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfMtu
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The size of the largest datagram which can be sent/received on the 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.
What is cnt2XIfMtu?
This Integer32 reports the maximum transmission unit, in octets, for this extended-table interface row, matching the same meaning as the base table's MTU field. An administrator compares it against the base table's value for the same interface to confirm consistency, and uses it to plan for fragmentation-free transfers. For example, cnt2XIfMtu reporting 4470 tells the admin this interface supports FDDI-sized frames rather than the 1500-byte limit typical of plain Ethernet.
