callHistoryRetainTimer
Module: DIAL-CONTROL-MIB
OID (symbolic): DIAL-CONTROL-MIB::callHistoryRetainTimer
OID (numeric): 1.3.6.1.2.1.10.21.1.4.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The minimum amount of time that an callHistoryEntry will be maintained before being deleted. A value of 0 will prevent any history from being retained in the callHistoryTable, but will neither prevent callCompletion traps being generated nor affect other tables.
What is callHistoryRetainTimer?
This number specifies how many seconds to keep each call record before deleting it; operators can adjust it. Engineers use this to enforce retention policies for billing audits and compliance. Setting it to 86400 retains records for 24 hours.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.21.1.4.2 snmpwalk -v2c -c public <target> DIAL-CONTROL-MIB::callHistoryRetainTimer
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.10.21.1.4.2.1 snmpget -v2c -c public <target> DIAL-CONTROL-MIB::callHistoryRetainTimer.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.10.21.1.4.2.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> callHistoryRetainTimer.1
