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 USR-IP-CFG-MIB?

USR-IP-CFG-MIB is a CommWorks (a 3Com company, formerly U.S. Robotics' carrier-access division) proprietary MIB configuring per-network IP routing behavior on commWorks access-server platforms. Its network-configuration table, keyed by network name, records broadcast address, reassembly max size, active routing protocol (none/RIPv1/RIPv2/OSPF), and a set of RIP-specific policy toggles — send-default-route, send-routes, send-subnets-only, accept-default-route, silent mode, split-horizon, poison-reverse, flash-update, simple authentication (with key), and RIPv1-compatibility/receive-version controls — plus routing metric and export metric. As a configuration MIB it lets an administrator audit which RIP policy toggles are active on a given interface, particularly useful when diagnosing route-advertisement inconsistencies. It is deployed on commWorks (3Com) access-server platforms. Engineers can download the USR-IP-CFG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in USR-IP-CFG-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 checks usrIpCfgNetSplitHorizonPolicy and usrIpCfgNetPoisonReversePolicy to confirm RIP loop-prevention settings match the network design before troubleshooting a routing loop.

OIDs

OID symbolic	OID numeric	Type	Access	Description
usrIpCfg	1.3.6.1.4.1.429.4.13			The commWorks enterprise defined MIB objects IP Configuration.
usrIpCfgNetworkTable	1.3.6.1.4.1.429.4.13.1		not-accessible	This table is the same as the usrIpNetworkTable definied above, with the exception that it is indexed by the Network Name defined in the usrCfgNetworkTable. This table will be used only by the the Configuration File Manager process to load permament configuration file records for named networks at system boot time. Any attempt to set this table from either the CLI process or SNMP will fail.
usrIpCfgNetworkEntry	1.3.6.1.4.1.429.4.13.1.1		not-accessible	A (conceptual) entry for one IP Network.
STR usrIpCfgNetName	1.3.6.1.4.1.429.4.13.1.1.1	UsrDisplayString	not-accessible	The name of this network. Network names can either be assigned by a network administrator when the Network is created. Or it will generated by the Configuration Process when it adds the network to its internal table.
I32 usrIpCfgNetBcastAddr	1.3.6.1.4.1.429.4.13.1.1.4	Integer32	read-write	The value of the least-significant bit in the IP broadcast address used for sending datagrams on the (logical) interface associated with the IP address of this entry. For example, when the Internet standard all-ones broadcast address is used, the value will be 1. This value applies to both the subnet and network broadcasts addresses used by the entity on this (logical) interface.
I32 usrIpCfgNetReasmMaxSize	1.3.6.1.4.1.429.4.13.1.1.5	Integer32	read-write	The size of the largest IP datagram which this entity can re-assemble from incoming IP fragmented datagrams received on this interface.
INT usrIpCfgNetRoutingProtocol	1.3.6.1.4.1.429.4.13.1.1.6	INTEGER	read-write	The routing protocol to be operated on this IP network. Currently, there are none, rip version 1 and rip version 2.
INT usrIpCfgNetSendDefaultRoutePolicy	1.3.6.1.4.1.429.4.13.1.1.7	INTEGER	read-write	Allows disabling or enabling of the send default route RIP policy. This policy is enabled by default.
INT usrIpCfgNetSendRoutesPolicy	1.3.6.1.4.1.429.4.13.1.1.8	INTEGER	read-write	Allows disabling or enabling of the send routes RIP policy. This policy is enabled by default.
INT usrIpCfgNetSendSubnetsOnlyPolicy	1.3.6.1.4.1.429.4.13.1.1.9	INTEGER	read-write	Allows disabling or enabling of the send subnets only RIP policy. This policy is enabled by default.
INT usrIpCfgNetAcceptDefaultRoutePolicy	1.3.6.1.4.1.429.4.13.1.1.10	INTEGER	read-write	Allows disabling or enabling of the accept default route RIP policy. This policy is disabled by default.
INT usrIpCfgNetSilentPolicy	1.3.6.1.4.1.429.4.13.1.1.11	INTEGER	read-write	Allows disabling or enabling of the silent policy. This policy is disabled by default.
INT usrIpCfgNetSplitHorizonPolicy	1.3.6.1.4.1.429.4.13.1.1.12	INTEGER	read-write	Allows disabling or enabling of the split horizon RIP policy. This policy is enabled by default.
INT usrIpCfgNetPoisonReversePolicy	1.3.6.1.4.1.429.4.13.1.1.13	INTEGER	read-write	Allows disabling or enabling of the poison reverse RIP policy. This policy is enabled by default.
