What Is Dell-rlIP-MIB?

Dell-rlIP-MIB is a private enterprise MIB module used on Dell networking switches (its 'rl' prefix reflects the RapidCity/switch-management lineage common to Dell's managed switch line) to represent Layer 3 IP addressing information rather than general chassis health. It exposes a table of configured IP addresses per interface, including address family/type, the address value itself, how the address was assigned (manual, DHCP, SLAAC, etc.), its associated prefix, and lifecycle timestamps for when each entry was created or last changed. In terms of monitoring hardware/software status, its main value is tracking configuration-state health: whether an interface's IP address entry is active, deprecated, duplicate, or tentative, and detecting unexpected re-addressing events via the change timestamp rather than reporting CPU, temperature, or power metrics. It mirrors object patterns from the standard IETF IP-MIB/INET-ADDRESS-MIB address table, so it is effectively a Dell-proprietary counterpart layered on those conventions. It is typically deployed by network management systems polling Dell enterprise switches to audit IPv6/IPv4 address assignment and catch addressing misconfigurations. Engineers can download the Dell-rlIP-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

An administrator polls rlIpAddressTable / rlIpAddressEntry, indexed by rlIpAddressIfIndex, to enumerate every address configured on a switch interface along with its rlIpAddressAddrType and rlIpAddressAddr. Cross-referencing rlIpAddressStatus with rlIpAddressCreated and rlIpAddressLastChanged flags an address that recently transitioned to an invalid or duplicate state, which can indicate an addressing conflict introduced by a misconfigured neighbor. rlIpAddressOrigin further distinguishes manually assigned addresses from those learned via DHCP or IPv6 stateless autoconfiguration, helping isolate whether an unexpected address change was operator-driven or protocol-driven.

What Can Be Monitored

IP address assignment status
address origin (manual/DHCP/SLAAC)
address creation/last-changed timestamps
interface-to-address mapping
address prefix and type

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
