cmAlarmVariable
Module: COPPER-MOUNTAIN-NETWORKS-DSL-MIB
OID (symbolic): COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmAlarmVariable
OID (numeric): 1.3.6.1.4.1.1996.20.13.1.1.3
Node type: OBJECT-TYPE
Type: OBJECT IDENTIFIER
Access: read-write
Description: The object identifier of the particular variable to be sampled. Only variables that resolve to an ASN.1 primitive type of INTEGER (INTEGER, Counter, Gauge, or TimeTicks) may be sampled.
Because SNMP access control is articulated entirely in terms of the contents of MIB views, no access control mechanism exists that can restrict the value of this object to identify only those objects that exist in a particular MIB view. Because there is thus no acceptable means of restricting the read access that could be obtained through the alarm mechanism, the probe must only grant write access to this object in those views that have read access to all objects on the probe.
What is cmAlarmVariable?
cmAlarmVariable is a read-write object identifier naming the specific MIB variable this alarm entry samples, which must resolve to an INTEGER-family type such as a Counter, Gauge, or TimeTicks. An administrator points this at whatever object they want threshold-based monitoring on, such as an error counter or a utilization gauge elsewhere in this same MIB. For example, an operator could set cmAlarmVariable to the OID of cmVBridgeNOverflow to get automatic threshold alerts if a bridge's MAC table starts overflowing frequently.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1996.20.13.1.1.3 snmpwalk -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmAlarmVariable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1996.20.13.1.1.3.1 snmpget -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmAlarmVariable.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1996.20.13.1.1.3.1 s <value>
