Description: GGSN memory overload protection is a mechanism to prevent GGSN from completely running out of memory when GGSN is running near its capacity or in some failure scenarios like CG down. A protection mechanism was put into place where charging triggers would be ignored, PDP create would be rejected, PDP update request will delete PDP, once the available memory on the GGSN drops below a configured threshold.
Charging triggers occurs due to certain criteria's like volume limit, time limit. When one of the conditions is met , the CDR's are closed and will be updated to the charging gateway.
What is cGgsnMemoryThreshold?
Sets the memory usage threshold used by the GGSN's memory overload protection mechanism, which suppresses charging triggers to prevent the device from running out of memory during high load or failure conditions like a downed charging gateway.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.240.1.3.11 snmpwalk -v2c -c public <target> CISCO-GGSN-MIB::cGgsnMemoryThreshold
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.240.1.3.11.1 snmpget -v2c -c public <target> CISCO-GGSN-MIB::cGgsnMemoryThreshold.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.9.9.240.1.3.11.1 i <value>
