cmEthernetNetPortMTU
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetNetPortMTU
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.7.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This object provides the MTU on the Ethernet Network Port.
What is cmEthernetNetPortMTU?
This read-write Integer32 sets the Maximum Transmission Unit, in bytes, that an Ethernet Network Port will accept or transmit. Admins configure MTU to match end-to-end path requirements, since a mismatch between this port's MTU and connected equipment causes oversized frames to be dropped or fragmented unexpectedly. For example, when provisioning a service that carries Q-in-Q double-tagged jumbo frames, an admin would raise cmEthernetNetPortMTU above the standard 1518 bytes to accommodate the extra tag and payload overhead.
