mlmLock
Module: MLM-MIB
OID (symbolic): MLM-MIB::mlmLock
OID (numeric): 1.3.6.1.4.1.99.42.1.1
Node type: OBJECT-TYPE
Type: TestAndIncr
Access: read-write
Description: This variable is used for creating new rows in the mlmCompileTable. When creating a new row, this variable must be set as well as the mlmRowStatus. If the value it is set to does not equal its current value, the set completely fails. A manager should only perform set requests on rows in the mlmCompileTable which it has created using mlmLock. The value of mlmLock is equal to the first unused row in the mlmCompileTable.
What is mlmLock?
A TestAndIncr semaphore used to safely reserve a new row in the mlmCompileTable: a manager must read the current value and include that same value in the set that creates the row, or the set fails, preventing two managers from clobbering each other's new script entries.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.99.42.1.1 snmpwalk -v2c -c public <target> MLM-MIB::mlmLock
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.99.42.1.1.1 snmpget -v2c -c public <target> MLM-MIB::mlmLock.1
