You cannot set this object to cleared (1) or indeterminate (2).

### Entries Retained in History Table (cGgsnHistNotifMaxLength)

The maximum number of entries to be retained in the cGgsnHistNotifTable. When the table is full, the oldest entries are removed to make space for new entries.

### Index of Recent Entry (cGgsnHistNotifLatestIndex)

The value of cGgsnHistNotifIndex for the most recently created entry in cGgsnHistNotifTable.

### Method Used to Obtain Address (cGgsnDefaultIpAllocationMethod)

The default method by which GGSN obtains address leases for mobile user sessions. The methods can be:

Method | Description

### PPP Virtual Template Interface (cGgsnPppVirtualTemplate)

The virtual template interface used by PPP Type PDPs.

### APN Virtual Template Interface (cGgsnPppRegenVirtualTemplate)

The virtual template interface used for PPP Regeneration by the APNs on which PPP Regeneration is configured.

A value zero indicates that no interface is specified.

### GTP Enabled Interfaces (cGgsnGtpEncapInterface)

ifIndex of the interface on which which gtp encapsulation is configured. Only one interface can be configured with gtp encapsulation on GGSN. A value zero indicates that no interface is configured with gtp encapsulation.

### GPRS Image Configuration (cGgsnConfigVersion)
