Description: Provides Radlan-specific IP management extensions beyond the standard IP-MIB.

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-rlIP-MIB?

RADLAN-rlIP-MIB is a Marvell/RADLAN private enterprise MIB extending standard IP address management on RADLAN-based switches, with a focus on representing auto-configured (e.g., SLAAC) and manually assigned IPv6 addresses per interface. It exposes an IP address table listing each address's type, the address itself, its origin (manual, DHCP, or auto-configuration), an associated general-prefix name, owning interface index, extended address type, prefix, status, and creation/last-changed timestamps. This is an IP-configuration and address-lifecycle monitoring MIB rather than a traffic-counter MIB: it confirms which addresses are active on which interface, whether an address was auto-configured versus statically assigned, and when it was created or last changed, helping diagnose IPv6 addressing problems such as an interface failing to receive an expected SLAAC address. It complements and overlaps with the standard IETF IP-MIB's ipAddressTable, adding RADLAN-specific origin and general-prefix tracking. It is typically deployed on RADLAN-based Layer 3 switches operating in dual-stack or IPv6 environments. Engineers can download the RADLAN-rlIP-MIB file directly to load it into their MIB browser.

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

Marvell/RADLAN-based Layer 3 switch/router
OEM routing switches licensing the RADLAN software stack
Marvell/RADLAN-based Layer 3 switches (OEM switch platforms)

Monitoring Examples

An administrator verifying IPv6 auto-configuration would poll rlIpAddressTable/rlIpAddressEntry for a given rlIpAddressIfIndex, checking rlIpAddressOrigin to confirm whether the address was assigned via SLAAC versus manually, and rlIpAddressLastChanged to see when it last updated. rlIpAddressPrefix and rlIpAddressGeneralPrefixName reveal which delegated IPv6 prefix the address derived from, useful when troubleshooting a prefix-delegation change that didn't propagate. If an expected auto-configured address is absent from rlIpAddressTable for an interface, that interface likely isn't receiving router advertisements correctly.

What Can Be Monitored

IP addresses assigned per interface
address origin (manual/auto-configured/DHCP)
address creation and last-changed time
associated IPv6 prefix / general-prefix name
address status

OIDs

OID symbolic	OID numeric	Type	Access	Description
rlIp	1.3.6.1.4.1.89.250			The private MIB module definition for Auto Configured IPv6 Address representation.
rlIpAddressTable	1.3.6.1.4.1.89.250.1		not-accessible	This table contains addressing information relevant to the entity's interfaces. in addition to ipAddressTable defined in standard MIB a represenattion of IPv6 addresses based on additionl address origin such as EUI-64, general prefix etc. In this case the address information is partial address information. Together with the address origin and the general prefix (when needed) user can construct full address information. The index (key) for this table includes this information additionally to the address.
rlIpAddressEntry	1.3.6.1.4.1.89.250.1.1		not-accessible	An address mapping for a particular interface.
IPt rlIpAddressAddrType	1.3.6.1.4.1.89.250.1.1.1	InetAddressType	not-accessible	The address type of rlIpAddressAddr.
IP rlIpAddressAddr	1.3.6.1.4.1.89.250.1.1.2	InetAddress	not-accessible	The IP address to which this entry's addressing information pertains. The address type of this object is specified in rlIpAddressAddrType. In case of auto-configure address such as eui-64, general-prefix and others it contains the partial address before appropriate manipulation. Implementors need to be aware that if the size of rlIpAddressAddr exceeds 116 octets, then OIDS of instances of columns in this row will have more than 128 sub-identifiers and cannot be accessed using SNMPv1, SNMPv2c, or SNMPv3.
NUM rlIpAddressOrigin	1.3.6.1.4.1.89.250.1.1.3	RlIpAddressOriginTC	not-accessible	The origin of the address.
STR rlIpAddressGeneralPrefixName	1.3.6.1.4.1.89.250.1.1.4	DisplayString	not-accessible	The name assigned to the prefix.
NUM rlIpAddressIfIndex	1.3.6.1.4.1.89.250.1.1.5	InterfaceIndex	read-create	The index value that uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.
INT rlIpAddressExtdType	1.3.6.1.4.1.89.250.1.1.6	INTEGER	read-create	Extend standard field ipAddressType to multicast
NUM rlIpAddressPrefix	1.3.6.1.4.1.89.250.1.1.7	RowPointer	read-only	A pointer to the row in the prefix table to which this address belongs. May be { 0 0 } if there is no such row.
ADR rlIpAddressStatus	1.3.6.1.4.1.89.250.1.1.8	IpAddressStatusTC	read-create	The status of the address, describing if the address can be used for communication. In the absence of other information, an IPv4 address is always preferred(1).
TIM rlIpAddressCreated	1.3.6.1.4.1.89.250.1.1.9	TimeStamp	read-only	The value of sysUpTime at the time this entry was created. If this entry was created prior to the last re- initialization of the local network management subsystem, then this object contains a zero value.
TIM rlIpAddressLastChanged	1.3.6.1.4.1.89.250.1.1.10	TimeStamp	read-only	The value of sysUpTime at the time this entry was last updated. If this entry was updated prior to the last re- initialization of the local network management subsystem, then this object contains a zero value.
ROW rlIpAddressRowStatus	1.3.6.1.4.1.89.250.1.1.11	RowStatus	read-create	The status of this conceptual row. The RowStatus TC requires that this DESCRIPTION clause states under which circumstances other objects in this row can be modified. The value of this object has no effect on whether other objects in this conceptual row can be modified. A conceptual row can not be made active until the rlIpAddressIfIndex has been set to a valid index.
STO rlIpAddressStorageType	1.3.6.1.4.1.89.250.1.1.12	StorageType	read-create	The storage type for this conceptual row. If this object has a value of 'permanent', then no other objects are required to be able to be modified.
ADR rlIpAddressExtdPrefixLength	1.3.6.1.4.1.89.250.1.1.13	InetAddressPrefixLength	read-create	The prefix length of this address.
IP rlIpAddressCompleteAddr	1.3.6.1.4.1.89.250.1.1.14	InetAddress	read-only	The Complete IP address to which this entry's addressing information pertains. In case of auto-configure address such as eui-64, general-prefix and others it contains the complete address after appropriate manipulation
