cnt2XIfPromiscuousMode
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfPromiscuousMode
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.14
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This object has a value of false(2) if this interface only accepts packets/frames that are addressed to this station. This object has a value of true(1) when the station accepts all packets/frames transmitted on the media. The value true(1) is only legal on certain types of media. If legal, setting this object to a value of true(1) may require the interface to be reset before becoming effective.
The value of ifPromiscuousMode does not affect the reception of broadcast and multicast packets/frames by the interface.
What is cnt2XIfPromiscuousMode?
This TruthValue flags whether the interface only accepts frames addressed to its own station, value false, or accepts every frame transmitted on the shared media, value true. An administrator cares because finding this unexpectedly set to true on a production port could mean unauthorized packet sniffing or monitoring software has been enabled there. For example, discovering cnt2XIfPromiscuousMode reporting true(1) on a port the admin didn't configure that way would prompt an investigation into who enabled it and why.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.333.2.1.2.3.1.14 snmpwalk -v2c -c public <target> CNT21-MIB::cnt2XIfPromiscuousMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.333.2.1.2.3.1.14.1 snmpget -v2c -c public <target> CNT21-MIB::cnt2XIfPromiscuousMode.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.333.2.1.2.3.1.14.1 s <value>
