agentEngineID
Module: XEDIA-MIB
OID (symbolic): XEDIA-MIB::agentEngineID
OID (numeric): 1.3.6.1.4.1.838.1.6.1
Node type: OBJECT-TYPE
Type: DisplayString
Access: read-write
Description: The configured SNMP EngineID used for SNMPv3 packets. This object can be used to override automatic engine id assignment. If this object is set, care must be taken to ensure its uniqueness within the SNMP Domain. Additionally, setting this object may result in the initialization of snmpEngineBoots. Normally, this has the desired affect, but if the engine ID is reset to an old value, previously captured PDUs may again apear to be valid, since the number of restarts has been reset.
Setting this value results in the following:
> a null EngineID results in the normal 'MAC address' of the SNMP EngineID encoding as per rfc2271.
> an ASCII string results in the normal 'Text' administratively assigned value.
> an ASCII string beginning with a '-' results in a straight, display string implementation of only readable/printable bytes. This does NOT abide by the recommendation in rfc2271. Typically, this is only needed with primative manager stations that have trouble with non-ascii data.
What is agentEngineID?
Overrides the agent's automatically assigned SNMPv3 EngineID; setting it can reset snmpEngineBoots, and resetting it back to an old value risks making previously captured PDUs appear valid again, so it should be changed with care and must stay unique across the SNMP domain.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.838.1.6.1 snmpwalk -v2c -c public <target> XEDIA-MIB::agentEngineID
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.838.1.6.1.1 snmpget -v2c -c public <target> XEDIA-MIB::agentEngineID.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.838.1.6.1.1 s <value>
