Description: Manages Cisco Diameter Session Gateway functions, monitoring protocol conversion, session routing, and AAA proxy operations.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-DIAMETER-SG-MIB?

CISCO-DIAMETER-SG-MIB manages Cisco's Diameter Server Group functionality, used in mobile/AAA infrastructure where Diameter servers handle authentication, authorization, and accounting for services such as Diameter-based session gateways. It exposes configuration tables for server groups and the individual Diameter servers within each group, including group/server names, storage type, and row status for provisioning via SNMP SET. This is primarily a software/configuration-state monitoring MIB: it lets an operator confirm which Diameter servers are configured in a group, their administrative row status, and whether the configuration is persisted, which is critical for diagnosing AAA/session-routing service availability. It relies on the standard SNMPv2 RowStatus/StorageType textual conventions (RFC 2579) for its provisioning model. It is typically deployed on Cisco platforms acting as Diameter Session Gateways within mobile core or broadband AAA infrastructure. Engineers can download the CISCO-DIAMETER-SG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-DIAMETER-SG-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An administrator would walk cdsgServerGroupTable/cdsgServerGroupEntry to confirm all expected Diameter server groups (cdsgServerGroupName) show cdsgServerGroupRowStatus active, then drill into cdsgServerTable/cdsgServerEntry to verify each cdsgServerName within a group has the expected cdsgServerRowStatus. An unexpected notInService or notReady row status on a server entry would indicate a misconfigured or failed Diameter server impacting AAA/session routing for that group.

What Can Be Monitored

Diameter server group configuration
server group row/storage status
individual server entries per group
server row status

OID symbolic	OID numeric	Type	Access	Description
ciscoDiameterSGMIB	1.3.6.1.4.1.9.10.132			The MIB module for Cisco's Diameter Server Group Entities. This MIB describes the SNMP MIB objects that are supported in order to provide the ability to fetch/configure the Diameter Server Groups.
ciscoDiameterSGMIBNotifs	1.3.6.1.4.1.9.10.132.0
ciscoDiameterSGMIBObjects	1.3.6.1.4.1.9.10.132.1
cdsgHostCfgs	1.3.6.1.4.1.9.10.132.1.1
cdsgServerGroupTable	1.3.6.1.4.1.9.10.132.1.1.1		not-accessible	The table listing the Diameter server group information. Entries are added to this table via cdsgServerGroupRowStatus in accordance with the RowStatus convention.
cdsgServerGroupEntry	1.3.6.1.4.1.9.10.132.1.1.1.1		not-accessible	A row entry representing a Diameter server group entry.
U32 cdsgServerGroupIndex	1.3.6.1.4.1.9.10.132.1.1.1.1.1	Unsigned32	not-accessible	A number uniquely identifying each Diameter Server Group. An index that uniquely represents a Server Group. This index is assigned arbitrarily by the SNMP engine and is not saved over reloads.
STR cdsgServerGroupName	1.3.6.1.4.1.9.10.132.1.1.1.1.2	SnmpAdminString	read-create	The Server Group Name. It has to be unique and not an empty string.
STO cdsgServerGroupStorageType	1.3.6.1.4.1.9.10.132.1.1.1.1.3	StorageType	read-create	The storage type for this conceptual row. An agent implementing the table must allow adding cdsgServerGroupName into the table. None of the columnar objects is writable when the conceptual row is permanent.
ROW cdsgServerGroupRowStatus	1.3.6.1.4.1.9.10.132.1.1.1.1.4	RowStatus	read-create	The status of this conceptual row. To create a row in this table, a manager must set this object to either createAndGo(4) or createAndWait(5). Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the cdsgServerGroupRowStatus column is 'notReady'. In particular, a newly created row cannot be made active until the corresponding cdsgServerGroupName has been set. cdsgServerGroupName may not be modified while the value of this object is active(1): An attempt to set these objects while the value of cdsgServerGroupRowStatus is active(1) will result in an inconsistentValue error. Entries in this table with cdsgServerGroupRowStatus equal to active(1) remain in the table until destroyed. Entries in this table with cdsgServerGroupRowStatus equal to values other than active(1) will be destroyed after timeout (5 minutes). Upon reload, cdsgServerGroupIndex values may be changed.
cdsgServerTable	1.3.6.1.4.1.9.10.132.1.1.2		not-accessible	The table listing information regarding the server which are part of the Diameter server groups. Entries are added to this table via cdsgServerRowStatus in accordance with the RowStatus convention.
cdsgServerEntry	1.3.6.1.4.1.9.10.132.1.1.2.1		not-accessible	A row entry representing a Diameter server group.
U32 cdsgServerIndex	1.3.6.1.4.1.9.10.132.1.1.2.1.1	Unsigned32	not-accessible	A number uniquely identifying each Diameter Server. An index that uniquely represents a Server within a Server Group. This index is assigned arbitrarily by the SNMP engine and is not saved over reloads.
STR cdsgServerName	1.3.6.1.4.1.9.10.132.1.1.2.1.2	SnmpAdminString	read-create	The Server Name. It has to be unique and not an empty string.
STO cdsgServerStorageType	1.3.6.1.4.1.9.10.132.1.1.2.1.3	StorageType	read-create	The storage type for this conceptual row. An agent implementing the table must allow adding cdsgServerName into the table. None of the columnar objects is writable when the conceptual row is permanent.
ROW cdsgServerRowStatus	1.3.6.1.4.1.9.10.132.1.1.2.1.4	RowStatus	read-create	The status of this conceptual row. To create a row in this table, a manager must set this object to either createAndGo(4) or createAndWait(5). This table is an extended table to the cdsgServerGroupTable and so an entry here must have a corresponding parent entry in the cdsgServerGroupTable as well. This would map all such entries with the same cdsgServerEntry under one single cdsgServerGroupEntry i.e these servers are under the server group represented by the cdsgServerGroupEntry. Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the cdsgServerRowStatus column is 'notReady'. In particular, a newly created row cannot be made active until the corresponding cdsgServerName has been set. cdsgServerName may not be modified while the value of this object is active(1): An attempt to set these objects while the value of cdsgServerRowStatus is active(1) will result in an inconsistentValue error. Entries in this table with cdsgServerRowStatus equal to active(1) remain in the table until destroyed. Entries in this table with cdsgServerRowStatus equal to values other than active(1) will be destroyed after timeout (5 minutes). Upon reload, cdsgServerIndex values may be changed.
