Description: Provides management objects for monitoring Fibre Channel routing table entries and inter-fabric routing on Cisco MDS SAN switches.

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-FC-ROUTE-MIB?

CISCO-FC-ROUTE-MIB is a Cisco Systems Inc. proprietary MIB configuring and displaying Fibre Channel routing information on Cisco MDS/Nexus SAN switches. Its objects cover last route-table change time, route preference, a route-verification action (type, module, VSAN ID, route type, result, lock), a route table (destination address ID/mask, protocol, interface, domain ID, metric, type, permanent flag, row status), and a route-flow-statistics table (flow index/type, VSAN ID). As a configuration/status MIB it lets a SAN administrator confirm FC route preference and per-VSAN routing entries on a Cisco MDS/Nexus SAN switch. It is deployed on Cisco MDS/Nexus Fibre Channel SAN switches. Engineers can download the CISCO-FC-ROUTE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-FC-ROUTE-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

How to Use in IPNetwork Monitor

Example using fcRouteFlowFrames OID:

Select a Cisco MDS/Nexus Fibre Channel SAN switch as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type fcRouteFlowFrames into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The number of received frames for the flow created by the network manager. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoFcRouteMIB	1.3.6.1.4.1.9.9.284			The MIB module for configuring and displaying FC (Fibre Channel) Route Information.
ciscoFcRouteMIBObjects	1.3.6.1.4.1.9.9.284.1
fcRouteConfig	1.3.6.1.4.1.9.9.284.1.1
TIM fcRouteLastChangeTime	1.3.6.1.4.1.9.9.284.1.1.1	TimeStamp	read-only	The value of sysUpTime at the most recent time when a conceptual row was created, modified, or deleted in fcRouteTable. If no change has occurred since the last restart of the management system, then the value of this object is 0.
U32 fcRoutePreference	1.3.6.1.4.1.9.9.284.1.1.2	Unsigned32	read-write	The value of route preference.Route preference is the value used to select one route over other when more than one route to the same destination is learned from different protocols, peers, or static routes from end-users. The preference value is an arbitrary assigned value used to determine the order of routes to the same destination in a single routing database(RIB). The active route is chosen by the lowest preference value.
INT fcRouteVerifyAction	1.3.6.1.4.1.9.9.284.1.1.3	INTEGER	read-write	The action to perform a consistency check of fcRouteTable. none (1) - no action verify (2) - perform verify action Writing verify(2) does a consistency check of the fcRouteTable with either one of the following: - with routeTable in the persistent database if the fcRouteVerifyType value is pss(1) - with forwarding information base software tables on the module specified by fcRouteVerifyModule, if the fcRouteVerifyType value is fibShadow(2). - with forwarding information base hardware tables on the module specified by fcRouteVerifyModule if the fcRouteVerifyType value is fibHardware(3). This verify action is performed on the fcRouteTable for the VSAN specified by fcRouteVerifyVsanID and for the route entries of the type specified by fcRouteVerifyRouteType. The result is shown by fcRouteVerifyResult. If a verify, due to a previous action performed, is in progress in the agent, then setting the fcRouteVerifyAction to verify(2) again will fail. No verification is performed if the value is set to none(1). When read, this object always has the value 'none(1)'.
INT fcRouteVerifyType	1.3.6.1.4.1.9.9.284.1.1.4	INTEGER	read-write	The value used by fcRouteVerifyAction to perform the consistency check of fcRouteTable with: - route table in persistent database if value is pss(1) - forwarding information base software tables if value is fibShadow(2) - forwarding information base hardware tables if value is fibHardware(3).
PHY fcRouteVerifyModule	1.3.6.1.4.1.9.9.284.1.1.5	PhysicalIndex	read-write	This value identifies a particular line card module according to that module's value of entPhysicalIndex in the entPhysicalTable of the ENTITY-MIB (RFC 2737). The forwarding information base present on this module is checked for consistency with the fcRouteTable. The value of this object is relevant only if fcRouteVerifyType is either fibShadow(2) or fibHardware(3).
VSA fcRouteVerifyVsanID	1.3.6.1.4.1.9.9.284.1.1.6	VsanIndex	read-write	The value specifies the VSAN id. The fcRouteTable entries and the entries in the table specified by fcRouteVerifyType is checked for consistency for the same VSAN id specified by this object.
INT fcRouteVerifyRouteType	1.3.6.1.4.1.9.9.284.1.1.7	INTEGER	read-write	The value used by fcRouteVerifyAction to perform the consistency check of fcRouteTable. If the value is unicast(1) then only unicast entries in fcRouteTable and the entries in the table specified by fcRouteVerifyType are checked. If value is multicast(2) then only multicast entries in fcRouteTable and the entries in the table specified by fcRouteVerifyType are checked. If value is label(3) then only label entries in fcRouteTable and the entries in the table specified by fcRouteVerifyType are checked.
STR fcRouteVerifyResult	1.3.6.1.4.1.9.9.284.1.1.8	SnmpAdminString	read-only	The object displays the details of the first inconsistency that occured from the check. If the check passes successfully then this will be a zero-length string.
TES fcRouteVerifyLock	1.3.6.1.4.1.9.9.284.1.1.9	TestAndIncr	read-write	This object is used to facilitate the verify action performed using 'fcRouteVerifyAction' by multiple managers. The procedure to perform the action by the NMS is as follows: 1. Retrieve the value of fcRouteVerifyLock. 2. Set the value of fcRouteVerifyLock to the retrieved value, and in the same PDU provide the following values: fcRouteVerifyAction to 'verify(2)' fcRouteVerifyType,fcRouteVerifyVsanID, fcRouteVerifyRouteType and fcRouteVerifyModule. Note, fcRouteVerifyModule is relevent only if fcRouteVerifyType is either 'fibShadow(2)' or fibHardware(3). 3. If the set fails repeat steps 1-2. 4. Retrieve the value of fcRouteVerifyLock and fcRouteVerifyResult in the same pdu. 5. If 'fcRouteVerifyLock' value is not one greater than the retrieved value of 'fcRouteVerifyLock' in step-1 than repeat steps 1-4.
fcRouteTable	1.3.6.1.4.1.9.9.284.1.1.10		not-accessible	The local system's Fibre Channel Routing table. This table lists all the routes that is configured/ calculated at the local system. Traffic through the TL-Port (translation port) uses the R-CTL field in the FC protocol header. During forwarding, this R-CTL field is part of the the value looked-up in the route table for matching. The value of the object fcRoutePreference is used to select one route over other when more than one route to the same destination is learned from different protocols, peers, or static routes from end-users. Only the entries configured by the user, which are fcRouteProto of type netmgmt(3), can be deleted by the user.
fcRouteEntry	1.3.6.1.4.1.9.9.284.1.1.10.1		not-accessible	Each entry contains a route to a particular destination in a particular VSAN via a particular output interface, and learned in a particular manner.
ADR fcRouteDestAddrId	1.3.6.1.4.1.9.9.284.1.1.10.1.1	FcAddressId	not-accessible	The destination FC-ID of this route.
ADR fcRouteDestMask	1.3.6.1.4.1.9.9.284.1.1.10.1.2	FcAddressId	not-accessible	Indicate the mask to be logical-ANDed with the destination address Id before being compared to the value in the fcRouteDestAddrId field. This can only be 255.255.255 or 255.255.0 or 255.0.0 .
INT fcRouteProto	1.3.6.1.4.1.9.9.284.1.1.10.1.3	INTEGER	not-accessible	The routing mechanism via which this route was learned. other(1) - not specified local(2) - local interface netmgmt(3)- static route The following are all dynamic routing protocols fspf(4) - Fibre Shortest Path First mpls(5) - Multiple Protocol Label Switching. multicast(6) - multicast routes.
NUM fcRouteInterface	1.3.6.1.4.1.9.9.284.1.1.10.1.4	InterfaceIndex	not-accessible	The ifIndex value, which identifies the local interface through which the next hop of this route should be reached. If the interface type is TL-Port then R-CTL field in the FC protocol header is also used for look-up in the route table during forwarding. Only interfaces of type Fibre Channel and Port Channel are allowed.
U32 fcRouteDomainId	1.3.6.1.4.1.9.9.284.1.1.10.1.5	Unsigned32	read-create	The domain ID of next hop switch. However this object, when read, could have a value zero if value of fcRouteProto is 'local'.
U32 fcRouteMetric	1.3.6.1.4.1.9.9.284.1.1.10.1.6	Unsigned32	read-create	The routing metric for this route. The use of this object is dependent on fcRouteProto used.
INT fcRouteType	1.3.6.1.4.1.9.9.284.1.1.10.1.7	INTEGER	read-create	The type of route. local(1): refers to a route for which the next hop is the final destination; remote(2): refers to a route for which the next hop is not the final destination. This object is not relevent for multicast and broadcast route entries.
T/F fcRoutePermanent	1.3.6.1.4.1.9.9.284.1.1.10.1.8	TruthValue	read-create	The value if true(1), indicates the route is not to be removed from the relevant Forwarding information base even if the port is operationally 'down'. If false(2), the route is removed from the relevant Forwarding information base (FIB) if the port is operationally 'down'. This object is not relevent for multicast and broadcast route entries.

fcRouteStatistics	1.3.6.1.4.1.9.9.284.1.2
fcRouteFlowStatTable	1.3.6.1.4.1.9.9.284.1.2.1		not-accessible	The table to configure and show the ingress traffic counters on physical components (e.g., Linecards). The user has the option of configuring counters depending on the bits selected for the object fcRouteFlowType. If the user selects only vsanId(0) bit for all the entries, then no more than 1024 entries can be created. If the user selects all the 4 bits, vsanId(0), destId(1), srcId(2), port(3), for some entries, then additional entries can be created, up to a maximum of 2048 entries. For statistics collection R-CTL is not part of the the value looked-up in the route table, so the counters are updated immaterial of R-CTL field.
fcRouteFlowStatEntry	1.3.6.1.4.1.9.9.284.1.2.1.1		not-accessible	Each entry provides information on the ingress traffic counters at the physical component indicated by entPhysicalIndex. Entries can only be created for physical components, e.g.,line cards, which support this type of ingress traffic counters.
