Description: Dell Force10 MIB for IS-IS routing protocol management and statistics on Dell Force10/FTOS networking platforms.

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 F10-ISIS-MIB?

F10-ISIS-MIB is a Dell Force10/FTOS proprietary MIB for managing and monitoring the IS-IS routing protocol on Dell Networking OS switches and routers. It exposes configuration and status objects for IS-IS overload behavior (both IPv4 and IPv6), including system-wide overload-set controls and per-level overload state in a level table, plus notifications for protocol events. Its monitoring value is squarely software/protocol status: administrators track whether a router is in overload state (signaling it should be routed around) and per-IS-IS-level operational state rather than any physical hardware sensor. As an IS-IS implementation it depends conceptually on the ISO 10589 IS-IS standard and interoperates with standard IS-IS MIB concepts, though it is Dell's own object tree. It is deployed in Dell Force10/FTOS-based core and data-center networks running IS-IS as the IGP. Network engineers evaluating or troubleshooting this functionality can download the F10-ISIS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in F10-ISIS-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.

Supported Devices

Dell Force10 switches
Dell Networking OS (FTOS) routers

Monitoring Examples

An administrator would poll f10IsisSysLevelTable/f10IsisSysLevelEntry, keyed by f10IsisSysLevelIndex, to check f10IsisSysLevelOverloadState and f10IsisSysLevelV6OverloadState for each IS-IS level on the router. Seeing an overload state unexpectedly set (or the f10IsisSysOloadSetOverload flag enabled) after a reload would explain why the router is being avoided for transit traffic even though its interfaces are up. The f10IsisSysOloadWaitForBgp and f10IsisSysOloadSetOloadOnStartupUntil objects would be checked to confirm whether overload-on-startup timing is behaving as configured.

What Can Be Monitored

IS-IS overload state (IPv4 and IPv6)
overload-on-startup timer
wait-for-BGP overload behavior
per-level IS-IS state

T/F f10IsisSysOloadSetOverload	1.3.6.1.4.1.6027.3.18.1.1	TruthValue	read-write	Administratively set the overload bit for both levels. The overload bit MUST continue to be set if the implementation runs out of memory, independent of this variable.
U32 f10IsisSysOloadSetOloadOnStartupUntil	1.3.6.1.4.1.6027.3.18.1.2	Unsigned32	read-write	If this object is within the range of 5 to 86400, the overload bit is set for both levels when isis is enabled for next startup. The overload bit remains set for seconds.f10IsisSysOloadSetOloadOnStartupUntil. When f10IsisSysOloadSetOloadOnStartupUntil seconds have elapsed,the overload flag remains set if the implementation has run out of memory. Else, the system clears the overload bit. In addition to the value limits, a value of zero removes the config so that it will not be effected in the next startup.
U32 f10IsisSysOloadWaitForBgp	1.3.6.1.4.1.6027.3.18.1.3	Unsigned32	read-write	If this object is within the range of 5 to 86400, the overload bit is set for both levels when isis is enabled for next startup. The overload bit remains set until BGP has converged or for seconds.f10IsisSysOloadWaitForBgp, whichever occurs first. A value of zero removes the config so that it will not be effected for the next startup.
T/F f10IsisSysOloadV6SetOverload	1.3.6.1.4.1.6027.3.18.1.4	TruthValue	read-write	Administratively set the overload bit for both levels. The overload bit MUST continue to be set if the implementation runs out of memory, independent of this variable.
U32 f10IsisSysOloadV6SetOloadOnStartupUntil	1.3.6.1.4.1.6027.3.18.1.5	Unsigned32	read-write	If this object is within the range of 5 to 86400, the overload bit is set for both levels for IPV6 when isis is enabled for next startup. The overload bit remains set for seconds.f10IsisSysOloadV6SetOloadOnStartupUntil. When f10IsisSysOloadV6SetOloadOnStartupUntil seconds have elapsed, the overload flag remains set if the implementation has run out of memory. Else, the system clears the overload bit. A value of zero removes the config so that it will not be effected in the next startup.
U32 f10IsisSysOloadV6WaitForBgp	1.3.6.1.4.1.6027.3.18.1.6	Unsigned32	read-write	If this object is within the range of 5 to 86400, the overload bit is set for both levels when isis is enabled for next startup. The overload bit remains set until BGP has converged for both IPV4 and IPV6 neighbours or for seconds.f10IsisSysOloadV6WaitForBgp, whichever occurs first. A value of zero removes the config so that it will not be effected for the next startup.
f10IsisSysLevelTable	1.3.6.1.4.1.6027.3.18.1.7		not-accessible	Level specific information about the System.
f10IsisSysLevelEntry	1.3.6.1.4.1.6027.3.18.1.7.1		not-accessible	Each row describes variables configured for Area or Domain. Configured values MUST survive an agent reboot.
F10 f10IsisSysLevelIndex	1.3.6.1.4.1.6027.3.18.1.7.1.1	F10IsisISLevel	not-accessible	The level that this entry describes.
T/F f10IsisSysLevelOverloadState	1.3.6.1.4.1.6027.3.18.1.7.1.2	TruthValue	read-only	The Overload state of the database at this level. If the value is true, it indicates a database that is low on an essential resource, such as memory. The administrator may indirectly force the state to overloaded by setting the object f10IsisSysOloadSetOverload. If the state is overloaded, we originate LSPs with the Overload bit set.
T/F f10IsisSysLevelV6OverloadState	1.3.6.1.4.1.6027.3.18.1.7.1.3	TruthValue	read-only	The Overload state of the IPV6 database at this level. If the value is true, it indicates a database that is low on an essential resource, such as memory. The administrator may indirectly force the state to overloaded by setting the object f10IsisSysOloadV6SetOverload. If the state is overloaded, we originate LSPs with the Overload bit set.
