Description: Adds BGP routing configuration and status monitoring capabilities to Radlan/Marvell switch 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 RADLAN-BGP?

RADLAN-BGP is a private MIB module developed by Radlan (now part of Marvell) extending Border Gateway Protocol configuration and status monitoring on switch platforms built on Radlan/Marvell reference designs. It exposes BGP-specific configuration parameters and routing/peering status information layered on top of standard BGP MIB objects. While primarily a routing-configuration MIB, it can be used to check the software-level operational status of the BGP process, such as peer session states, which reflects the health of the routing control plane on the device. It notably extends and depends on the standard BGP4-MIB (RFC 4273) for baseline objects, adding vendor-specific enhancements. It is typically deployed on Layer 3 switches and small-to-midsize routers built on Radlan/Marvell switching silicon and software stacks. Engineers can download the RADLAN-BGP file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RADLAN-BGP. 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

Radlan/Marvell-based Layer 3 switches and routers

Monitoring Examples

An administrator would poll BGP peer status and configuration objects to confirm neighbor sessions are established and routes are being exchanged as expected on a Radlan-based switch. A peer stuck in an idle or connect state rather than established would reveal a misconfigured neighbor or network reachability problem. Vendor-specific extension objects would be checked alongside standard BGP4-MIB peer tables for a complete picture of routing health.

What Can Be Monitored

BGP peer session state
BGP configuration parameters
routing process status
peer-specific extensions beyond standard BGP4-MIB

OIDs

OID symbolic	OID numeric	Type	Access	Description
rlBgp	1.3.6.1.4.1.89.71			The private MIB module definition for RND BGP private MIB.
INT rlBgpMibVersion	1.3.6.1.4.1.89.71.1	INTEGER	read-only	BGP4 Mib version, the current version is 1.
rlBgpPeersExtTable	1.3.6.1.4.1.89.71.2		not-accessible	BGP peer table. Contains one entry per BGP peer, information about the connections with BGP peers.
rlBgpPeersExtEntry	1.3.6.1.4.1.89.71.2.1		not-accessible	Entry containing information about the connection with a BGP peer.
ROW rlBgpPeersExtRowStatus	1.3.6.1.4.1.89.71.2.1.1	RowStatus	read-write	The row status variable, used according to installation and removal conventions for conceptual rows. Setting this object to active(1) or createAndGo(4) results in the addition of the remote address of the peer. Destroying the entry or setting it to notInService(2) removes the remote address associated with the peer. The use of other values is implementation-dependent.
INT rlBgpPeersExtIsReflectorClient	1.3.6.1.4.1.89.71.2.1.2	INTEGER	read-write	This value indicates whether the given peer is a reflector client of this router, or not. A value of client indicates that this peer is a reflector client that is not fully meshed with other reflector clients. A value of meshedClient indicates that the peer is a reflector client and is fully meshed with all other clients because there is no route reflection. The default value is meshedClient.
T/F rlBgpPeersExtInConfederation	1.3.6.1.4.1.89.71.2.1.3	TruthValue	read-write	This value indicates whether the given peer is in our confederation or not.
INT rlBgpPeersExtRemAS	1.3.6.1.4.1.89.71.2.1.4	INTEGER	read-write	The remote autonomous system number which is configurable.
IP rlBgpClusterId	1.3.6.1.4.1.89.71.3	IpAddress	read-write	The configured Cluster-ID of the local router. A value of 0.0.0.0 indicates the absence of this value.
INT rlBgpConfederationId	1.3.6.1.4.1.89.71.4	INTEGER	read-write	The local Confederation Identification Number. A value of zero (0) indicates the absence of this value.
INT rlBgpEnable	1.3.6.1.4.1.89.71.5	INTEGER	read-write	This value indicates whether BGP is enable on this router or not.
INT rlBgpRouteReflectionEnable	1.3.6.1.4.1.89.71.6	INTEGER	read-write	This value indicates whether route reflection extension is enable on this router or not.
INT rlBgpASConfederationEnable	1.3.6.1.4.1.89.71.7	INTEGER	read-write	This value indicates whether AS confederation extension is enable on this router or not.
INT rlBgpRouteFlapDampeningEnable	1.3.6.1.4.1.89.71.8	INTEGER	read-write	This value indicates whether route flap dampening extension is enable on this router or not.
INT rlBgpCommunitiesEnable	1.3.6.1.4.1.89.71.9	INTEGER	read-write	This value indicates whether BGP communities extension is enable on this router or not.
INT rlBgpCapabilNegotEnable	1.3.6.1.4.1.89.71.10	INTEGER	read-write	This value indicates whether BGP capabilities negotiation extension is enable on this router or not.
