Description: Implements the IETF MSDP MIB for managing Multicast Source Discovery Protocol peers and SA cache.

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-IETF-MSDP-MIB?

CISCO-IETF-MSDP-MIB is a Cisco implementation of the IETF experimental draft MIB for Multicast Source Discovery Protocol (MSDP), a protocol used to interconnect multicast domains by sharing active-source information between rendezvous points (RPs) across autonomous systems. It exposes configuration data (enabling MSDP, cache lifetime, RP address) alongside operational/runtime state such as the number of active Source-Active (SA) cache entries, per-peer MSDP session tables, and SA-filtering request tables. As a monitoring resource it is used to track the software/protocol-level health of multicast routing - whether MSDP is enabled, how many SA cache entries are currently held, and whether configured MSDP peer sessions are up - plus fault notifications via the traps subtree when peer state changes. It is explicitly based on and mirrors the IETF draft-ietf-mboned-msdp-mib and depends on multicast routing context established by PIM-MIB/IGMP-related MIBs for full interpretation. It is deployed on Cisco routers running MSDP in multicast-enabled ISP or enterprise backbone networks that need to share multicast source reachability across PIM domains. Engineers can download the CISCO-IETF-MSDP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-IETF-MSDP-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

Cisco router running MSDP for inter-domain multicast

Monitoring Examples

An operator would poll cMsdpNumSACacheEntries to track how many active multicast sources are currently known via MSDP, and walk cMsdpPeerTable/cMsdpPeerEntry to confirm each configured MSDP peer session is established rather than idle or down. Checking cMsdpRequestsTable (keyed by cMsdpRequestsGroupAddress/cMsdpRequestsPeer) shows which SA-request filters are active per peer, and a sudden drop in cMsdpNumSACacheEntries combined with a peer entry going down would indicate a lost MSDP session disrupting inter-domain multicast source discovery. The cMsdpTraps notifications would additionally alert on such peer state changes without continuous polling.

What Can Be Monitored

MSDP enabled/disabled state
SA cache entry count
MSDP peer session status
SA cache lifetime
SA-request filter table per peer

How to Use in IPNetwork Monitor

Example using cMsdpPeerRPFFailures OID:

Select a Cisco router running MSDP for inter-domain multicast 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 cMsdpPeerRPFFailures 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 SA messages received from this peer which failed the Peer-RPF check. 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 Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

NTF cMsdpEstablished	1.3.6.1.4.1.9.10.130.1.1.0.1			The MSDP Established event is generated when the MSDP FSM enters the ESTABLISHED state.
NTF cMsdpBackwardTransition	1.3.6.1.4.1.9.10.130.1.1.0.2			The MSDPBackwardTransition Event is generated when the MSDP FSM moves from a higher numbered state to a lower numbered state.
T/F cMsdpEnabled	1.3.6.1.4.1.9.10.130.1.1.1	TruthValue	read-write	The state of MSDP on this MSDP speaker - globally enabled or disabled. Changes to this object should be stored to non-volatile memory.
TIK cMsdpCacheLifetime	1.3.6.1.4.1.9.10.130.1.1.2	TimeTicks	read-write	The lifetime given to SA cache entries when created or refreshed. This is the [SA-State-Period] in the MSDP spec. A value of 0 means no SA caching is done by this MSDP speaker. Changes to this object should be stored to non-volatile memory. This object does not measure time per se; instead, it is the delta from the time at which an SA message is received at which it should be expired if not refreshed. (i.e., it is the value of cMsdpSACacheExpiryTime immediately after receiving an SA message applying to that row.) As such, TimeInterval would be a more appropriate SYNTAX; it remains TimeTicks for backwards compatability.
G32 cMsdpNumSACacheEntries	1.3.6.1.4.1.9.10.130.1.1.3	Gauge32	read-only	The total number of entries in the SA Cache table.
cMsdpRequestsTable	1.3.6.1.4.1.9.10.130.1.1.4		not-accessible	The (conceptual) table listing group ranges and MSDP peers used when deciding where to send an SA Request message when required. If SA Requests are not enabled, this table may be empty. In order to choose a peer to whom to send an SA Request for a given group G, the subset of entries in this table whose (cMsdpRequestsPeerType, cMsdpRequestsPeer) tuple represents a peer whose cMsdpPeerState is established are examined. The set is further reduced by examining only those entries for which cMsdpPeerRequestsGroupAddressType equals the address type of G, and the entries with the highest value of cMsdpRequestsGroupPrefix are considered, where the group G falls within the range described by the combination of cMsdpRequestsGroup and cMsdpRequestsGroupPrefix. (This sequence is commonly known as a 'longest-match' lookup.) Finally, if multiple entries remain, the entry with the lowest value of cMsdpRequestsPriority is chosen. The SA Request message is sent to the peer described by this row.
cMsdpRequestsEntry	1.3.6.1.4.1.9.10.130.1.1.4.1		not-accessible	An entry (conceptual row) representing a group range used when deciding where to send an SA Request message.

IP cMsdpRequestsPeer	1.3.6.1.4.1.9.10.130.1.1.4.1.3	IpAddress	read-create	The peer to which MSDP SA Requests for groups matching this entry's group range will be sent. This object combined with cMsdpRequestsPeerType must match the INDEX of a row in the cMsdpPeerTable, and to be considered, this peer's cMsdpPeerState must be established.
ROW cMsdpRequestsStatus	1.3.6.1.4.1.9.10.130.1.1.4.1.4	RowStatus	read-create	The status of this row, by which new rows may be added to the table or old rows may be deleted.
cMsdpPeerTable	1.3.6.1.4.1.9.10.130.1.1.5		not-accessible	The (conceptual) table listing the MSDP speaker's peers.
cMsdpPeerEntry	1.3.6.1.4.1.9.10.130.1.1.5.1		not-accessible	An entry (conceptual row) representing an MSDP peer. If row creation is supported, dynamically added rows are added to the system's stable configuration (corresponding to a StorageType value of nonVolatile).

T/F cMsdpPeerProcessRequestsFrom	1.3.6.1.4.1.9.10.130.1.1.5.1.24	TruthValue	read-create	This object indicates whether or not to process MSDP SA Request messages from this peer. If True(1), MSDP SA Request messages from this peer are processed and replied to (if appropriate) with SA Response messages. If False(2), MSDP SA Request messages from this peer are silently ignored. It defaults to False when cMsdpCacheLifetime is 0 and True when cMsdpCacheLifetime is non-0. This object is deprecated because MSDP SA Requests were removed from the MSDP specification.
ROW cMsdpPeerStatus	1.3.6.1.4.1.9.10.130.1.1.5.1.25	RowStatus	read-create	The RowStatus object by which peers can be added and deleted. A transition to 'active' will cause the MSDP 'Enable MSDP peering with P' Event to be generated. A transition out of the 'active' state will cause the MSDP 'Disable MSDP peering with P' Event to be generated. Care should be used in providing write access to this object without adequate authentication. cMsdpPeerRemoteAddress is the only variable that must be set to a valid value before the row can be activated. Since this is the table's INDEX, a row can be activated by simply setting the cMsdpPeerStatus variable. It is possible to modify other columns in the same conceptual row when the status value is active(1).
I32 cMsdpPeerRemotePort	1.3.6.1.4.1.9.10.130.1.1.5.1.26	Integer32	read-only	The remote port for the TCP connection between the MSDP peers.

C32 cMsdpPeerInNotifications	1.3.6.1.4.1.9.10.130.1.1.5.1.31	Counter32	read-only	The number of MSDP Notification messages received from this peer. This object is deprecated because MSDP Notifications have been removed from the spec.
C32 cMsdpPeerOutNotifications	1.3.6.1.4.1.9.10.130.1.1.5.1.32	Counter32	read-only	The number of MSDP Notification messages transmitted to this peer. This object is deprecated because MSDP Notifications have been removed from the spec.
OCT cMsdpPeerLastError	1.3.6.1.4.1.9.10.130.1.1.5.1.33	OCTET STRING	read-only	The last error code and subcode received via Notification from this peer. If no error has occurred, this field is zero. Otherwise, the first byte of this two byte OCTET STRING contains the O-bit and error code, and the second byte contains the subcode. This object is deprecated because MSDP Notifications have been removed from the spec.
TIM cMsdpPeerDiscontinuityTime	1.3.6.1.4.1.9.10.130.1.1.5.1.34	TimeStamp	read-only	The value of sysUpTime on the most recent occasion at which one or more of this entry's counters suffered a discontinuity. See the DESCRIPTION of each object to see if it is expected to have discontinuities. These discontinuities may occur at peer connection establishment. If no such discontinuities have occurred since the last reinitialization of the local management subsystem, then this object contains a zero value.
cMsdpSACacheTable	1.3.6.1.4.1.9.10.130.1.1.6		not-accessible	The (conceptual) table listing the MSDP SA advertisements currently in the MSDP speaker's cache.
cMsdpSACacheEntry	1.3.6.1.4.1.9.10.130.1.1.6.1		not-accessible	An entry (conceptual row) representing an MSDP SA advertisement. The INDEX to this table includes cMsdpSACacheOriginRP for diagnosing incorrect MSDP advertisements; normally a Group and Source pair would be unique. Row creation is not permitted; msdpSACacheStatus may only be used to delete rows from this table.
IP cMsdpSACacheGroupAddr	1.3.6.1.4.1.9.10.130.1.1.6.1.1	IpAddress	not-accessible	The group address of the SA Cache entry.
IP cMsdpSACacheSourceAddr	1.3.6.1.4.1.9.10.130.1.1.6.1.2	IpAddress	not-accessible	The source address of the SA Cache entry.
IP cMsdpSACacheOriginRP	1.3.6.1.4.1.9.10.130.1.1.6.1.3	IpAddress	not-accessible	The RP of the SA Cache entry. This field is in the INDEX in order to catch multiple RP's advertising the same source and group.
IP cMsdpSACachePeerLearnedFrom	1.3.6.1.4.1.9.10.130.1.1.6.1.4	IpAddress	read-only	The peer from which this SA Cache entry was last accepted. This address must correspond to the cMsdpPeerRemoteAddress value for a row in the MSDP Peer Table. This should be 0.0.0.0 on the router that originated the entry.
IP cMsdpSACacheRPFPeer	1.3.6.1.4.1.9.10.130.1.1.6.1.5	IpAddress	read-only	The peer from which an SA message corresponding to this cache entry would be accepted (i.e. the RPF peer for cMsdpSACacheOriginRP). This may be different than cMsdpSACachePeerLearnedFrom if this entry was created by an MSDP SA-Response. This address must correspond to the cMsdpPeerRemoteAddress value for a row in the MSDP Peer Table, or may be 0.0.0.0 if no RPF peer exists.
C32 cMsdpSACacheInSAs	1.3.6.1.4.1.9.10.130.1.1.6.1.6	Counter32	read-only	The number of MSDP SA messages received relevant to this cache entry. This object must be initialized to zero when creating a cache entry.
C32 cMsdpSACacheInDataPackets	1.3.6.1.4.1.9.10.130.1.1.6.1.7	Counter32	read-only	The number of MSDP encapsulated data packets received relevant to this cache entry. This object must be initialized to zero when creating a cache entry.
TIK cMsdpSACacheUpTime	1.3.6.1.4.1.9.10.130.1.1.6.1.8	TimeTicks	read-only	The time since this entry was first placed in the SA cache. The first epoch is the time that the entry was first placed in the SA cache, and the second epoch is the current time.
TIK cMsdpSACacheExpiryTime	1.3.6.1.4.1.9.10.130.1.1.6.1.9	TimeTicks	read-only	The time remaining before this entry will expire from the SA cache. The first epoch is now, and the second epoch is the time that the entry will expire.
ROW cMsdpSACacheStatus	1.3.6.1.4.1.9.10.130.1.1.6.1.10	RowStatus	read-write	The status of this row in the table. The only allowable actions are to retrieve the status, which will be `active', or to set the status to `destroy' in order to remove this entry from the cache. Row creation is not permitted. No columnar objects are writable, so there are none that may be changed while the status value is active(1).
cMsdpMIBConformance	1.3.6.1.4.1.9.10.130.1.1.8
cMsdpMIBCompliances	1.3.6.1.4.1.9.10.130.1.1.8.1
cMsdpMIBCompliance	1.3.6.1.4.1.9.10.130.1.1.8.1.1			The compliance statement for entities which implement a pre- RFC version of MSDP. This statement is deprecated because it includes objects used for managing/monitoring aspects of MSDP that were removed before it was published as an RFC.
cMsdpMIBFullCompliance	1.3.6.1.4.1.9.10.130.1.1.8.1.2			The compliance statement for entities which implement MSDP (RFC3618).
cMsdpMIBReadOnlyCompliance	1.3.6.1.4.1.9.10.130.1.1.8.1.3			The compliance statement for entities which implement MSDP (RFC3618), but do not permit configuration (or only permit partial configuration) via SNMP.
cMsdpMIBGroups	1.3.6.1.4.1.9.10.130.1.1.8.2
cMsdpMIBGlobalsGroup	1.3.6.1.4.1.9.10.130.1.1.8.2.1			A collection of objects providing information on global MSDP state.
cMsdpMIBPeerGroup	1.3.6.1.4.1.9.10.130.1.1.8.2.2			A collection of objects for managing MSDP peers. This group is deprecated in favor of cMsdpMIBPeerGroup2 because it contains objects for managing aspects of MSDP that were removed before it was published as an RFC.
cMsdpMIBEncapsulationGroup	1.3.6.1.4.1.9.10.130.1.1.8.2.3			A collection of objects for managing encapsulations if the MSDP encapsulation interfaces are not given interface indices.
cMsdpMIBSACacheGroup	1.3.6.1.4.1.9.10.130.1.1.8.2.4			A collection of objects for managing MSDP SA cache entries.

cMsdpMIBRequestsGroup	1.3.6.1.4.1.9.10.130.1.1.8.2.6			A collection of objects for managing MSDP Request transmission. This group is deprecated because Requests were removed from MSDP before its publication as RFC.
cMsdpMIBRPGroup	1.3.6.1.4.1.9.10.130.1.1.8.2.7			A collection of objects for MSDP speakers that source MSDP messages.
cMsdpMIBMeshGroupGroup	1.3.6.1.4.1.9.10.130.1.1.8.2.8			A collection of objects for MSDP speakers that can participate in MSDP mesh groups.
cMsdpMIBPeerGroup2	1.3.6.1.4.1.9.10.130.1.1.8.2.9			A collection of objects for managing MSDP peers.
IP cMsdpRPAddress	1.3.6.1.4.1.9.10.130.1.1.11	IpAddress	read-write	The RP address used when sourcing MSDP SA messages. May be 0.0.0.0 on non-RP's. Changes to this object should be stored to non-volatile memory.
cMsdpMeshGroupTable	1.3.6.1.4.1.9.10.130.1.1.12		not-accessible	The (conceptual) table listing MSDP Mesh Group configuration.
cMsdpMeshGroupEntry	1.3.6.1.4.1.9.10.130.1.1.12.1		not-accessible	An entry (conceptual row) repesenting a peer in an MSDP Mesh Group. If row creation is supported, dynamically added rows are added to the system's stable configuration (corresponding to a StorageType value of nonVolatile).
STR cMsdpMeshGroupName	1.3.6.1.4.1.9.10.130.1.1.12.1.1	DisplayString	not-accessible	The name of the mesh group.
IP cMsdpMeshGroupPeerAddress	1.3.6.1.4.1.9.10.130.1.1.12.1.2	IpAddress	not-accessible	A peer address that is a member of the mesh group with name cMsdpMeshGroupName. The cMsdpMeshGroupPeerAddress must match a row in the cMsdpPeerTable.
ROW cMsdpMeshGroupStatus	1.3.6.1.4.1.9.10.130.1.1.12.1.3	RowStatus	read-create	This entry's status, by which new entries may be added to the table and old entries deleted. cMsdpMeshGroupName and cMsdpMeshGroupPeerAddress must be set to valid values before the row can be activated. Since these are the table's INDEX, a row can be activated by simply setting the cMsdpMeshGroupStatus variable. It is not possible to modify other columns in the same conceptual row when the status value is active(1), because there only other objects in the row are part of the INDEX. Changing one of these changes the row, so an old row must be deleted and a new one created.
