nwDecIVFwdIfMtu
Module: CTRON-DECIV-ROUTER-MIB
OID (symbolic): CTRON-DECIV-ROUTER-MIB::nwDecIVFwdIfMtu
OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.3.2.2.2.1.1.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Specifies the Maximum Transmission Unit (MTU) for DECnet packets on the router port for which the entry exists. This includes the DECnet header and data, but does not include framing.
What is nwDecIVFwdIfMtu?
nwDecIVFwdIfMtu is a read-write integer specifying the maximum transmission unit, in bytes, for DECnet packets sent on this router port, covering the DECnet header and data but not the underlying frame's own framing overhead. An admin adjusts this to match the DECnet payload size the port's underlying media and framing can actually carry without fragmentation problems. For example, lowering nwDecIVFwdIfMtu on a port using a WAN encapsulation with limited payload capacity keeps DECnet packets small enough to avoid being dropped or fragmented by that link.
