Cisco Ggsn Service Mode

1.3.6.1.4.1.9.9.240.1.3.12

GGSN supports this GPRS service mode for maintenance purposes. Two modes are supported in GGSN, operational and maintenance mode. 'inService' mode represents nominal operation, and there will be no change in the way the GGSN operates. 'maintenance' mode imposes restrictions, such as some of the configurations allowed by the GGSN, and no new PDPs will be accepted. 'maintenance' mode can be useful to make some changes to the configuration of the GGSN without affecting the existing PDPs. 'maintenance' mode gloablly applies to the GGSN, which means the whole box will be put in maintenance mode. There also exists APN level maintenance mode, which is defined in CISCO-GPRS_ACC-PT-MIB, and charging maintenance mode which is defined in CISCO-GPRS-CHARGING-MIB, which is out of scope of this MIB. Internally GGSN maintains three states (inService, maintenance and outOfService ), which can be viewed with cGgsnServiceModeStatus. The SNMP entity generates notification when switching modes. It uses the cGgsnInServiceNotif and cGgsnMaintenanceNotif for this purpose.
