nbsCmmcPortPreambleLen
Module: NBS-CMMC-MIB
OID (symbolic): NBS-CMMC-MIB::nbsCmmcPortPreambleLen
OID (numeric): 1.3.6.1.4.1.629.200.8.1.1.75
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Defines the length of the transmitted ethernet preamble for every frame on this port.
The value standard(2) indicates the standard 8 byte ethernet preamble should always be sent.
The value variable(3) indicates longer preambles may be sent.
The value notSupported(1) indicates preamble length is not configurable or not applicable for this port.
What is nbsCmmcPortPreambleLen?
This object controls the length of the Ethernet preamble transmitted by a port on NBS equipment. The standard preamble is 8 bytes, but some devices support variable-length preambles for compatibility or testing. Technicians configure this when connecting to non-standard equipment or when troubleshooting frame synchronization issues.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.629.200.8.1.1.75 snmpwalk -v2c -c public <target> NBS-CMMC-MIB::nbsCmmcPortPreambleLen
Get a specific instance (index 1):
