Description: Enterasys Networks MIB for creating and mapping MIB-II layer 3 interfaces to VLANs on Enterasys products.

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 ENTERASYS-VLAN-INTERFACE-MIB?

ENTERASYS-VLAN-INTERFACE-MIB is an Enterasys Networks proprietary MIB that manages the creation of standard MIB-II Layer 3 interfaces and their mapping to VLANs on Enterasys switches, enabling VLAN routing/SVI-style configuration. It exposes a table mapping each VLAN interface entry to a VLAN ID and an ifIndex, plus row-status and storage-type controls for creating or removing these mappings, along with a lookup table for reverse VLAN-to-index queries. Its monitoring value is primarily configuration-state visibility: confirming how many VLAN interfaces are currently configured versus the device's maximum, and verifying that each VLAN ID is correctly bound to the expected Layer 3 ifIndex for routing purposes. It explicitly builds on and extends the standard MIB-II interfaces model (IF-MIB/RFC 1213) by adding VLAN association. It is used on Enterasys Layer 3 switches and routers that route between VLANs. Engineers can download the ENTERASYS-VLAN-INTERFACE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ENTERASYS-VLAN-INTERFACE-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

Enterasys/Extreme Networks Layer 3 switches and routers

Monitoring Examples

An admin would check etsysVlanInterfaceCurrentEntries against etsysVlanInterfaceMaximumEntries to see how close the switch is to its VLAN-interface capacity limit before creating a new routed VLAN. Walking etsysVlanInterfaceTable/etsysVlanInterfaceEntry and cross-referencing etsysVlanInterfaceVlanID with etsysVlanInterfaceIfIndex confirms a given VLAN is bound to the correct Layer 3 interface, and etsysVlanInterfaceRowStatus reveals whether an entry is active or stuck in a notReady/notInService state after a failed configuration attempt.

What Can Be Monitored

VLAN interface count vs. maximum
VLAN ID to ifIndex mapping
interface row status
storage type of VLAN interface entries

OIDs

OID symbolic	OID numeric	Type	Access	Description
etsysVlanInterfaceMIB	1.3.6.1.4.1.5624.1.2.22			This MIB module defines a portion of the SNMP enterprise MIBs under the Enterasys enterprise OID pertaining to the creation of MIB-II interfaces and their mapping to VLANs for Enterasys products.
etsysVlanInterface	1.3.6.1.4.1.5624.1.2.22.1
U32 etsysVlanInterfaceMaximumEntries	1.3.6.1.4.1.5624.1.2.22.1.1	Unsigned32	read-only	The maximum number of entries that this entity supports in the etsysVlanInterfaceTable.
U32 etsysVlanInterfaceCurrentEntries	1.3.6.1.4.1.5624.1.2.22.1.2	Unsigned32	read-only	The current number of entries in the etsysVlanInterfaceTable on this entity.
etsysVlanInterfaceTable	1.3.6.1.4.1.5624.1.2.22.1.3		not-accessible	This table controls the dynamic creation of MIB-II interfaces and provides an associated mapping from the VLAN ID to the MIB-II interface index.
etsysVlanInterfaceEntry	1.3.6.1.4.1.5624.1.2.22.1.3.1		not-accessible	An entry that allows the creation of a MIB-II interface, maps it to the requested VLAN, and provides a mapping from the VLAN ID to the MIB-II interface index.
VLA etsysVlanInterfaceVlanID	1.3.6.1.4.1.5624.1.2.22.1.3.1.1	VlanIndex	not-accessible	The VLAN ID of the VLAN associated with this interface.
NUM etsysVlanInterfaceIfIndex	1.3.6.1.4.1.5624.1.2.22.1.3.1.2	InterfaceIndexOrZero	read-only	For conceptual rows in the active(1) state, this object returns the ifIndex of the interface mapped to this VLAN. The value of the ifIndex is determined by the agent on the managed entity. This object will return 0 (zero) when the conceptual row is in the notInService(2) state.
STO etsysVlanInterfaceStorageType	1.3.6.1.4.1.5624.1.2.22.1.3.1.3	StorageType	read-create	The memory realization of the conceptual row. volatile(2) -- is lost upon reboot. nonVolatile(3) -- is persistent across reboots. permanent(4) -- there are no writable objects. readOnly(5) -- agent created rows.
ROW etsysVlanInterfaceRowStatus	1.3.6.1.4.1.5624.1.2.22.1.3.1.4	RowStatus	read-create	This object manages the creation and deletion this entry. active - Indicates that this entry is available for use by the managed device. Transitions to this state will cause a a MIB-II interface to be created by the managed entity and mapped to the specified VLAN. The etsysVlanInterfaceIfIndex object will return the ifIndex of the newly created MIB-II interface. The ifEntry associated with this entry will only be allowed to have an ifAdminStatus and ifOperStatus of up(1) and will be read-only. notInService - Indicates that this entry exists in the agent but is unavailable for use. The etsysVlanInterfaceIfIndex object will return a value of 0 for entries in this state. State transitions from the active(1) state will cause the MIB-II interface mapped to this VLAN to be deleted. notReady - Should not be possible. createAndWait - A new entry will be created in this table for the specified VLAN and the new entry will transition to the notInService state. createAndGo - A new entry will be created in this table for the specified VLAN and the new entry will transition to the active state. destroy - Deletes this row and any MIB-II interface that may be associated with it.
etsysVlanInterfaceVlanLookup	1.3.6.1.4.1.5624.1.2.22.2
etsysVlanInterfaceVlanLookupTable	1.3.6.1.4.1.5624.1.2.22.2.1		not-accessible	This table provides a mapping from the MIB-II interface number to VLAN ID.
etsysVlanInterfaceVlanLookupEntry	1.3.6.1.4.1.5624.1.2.22.2.1.1		not-accessible	An entry that maps a MIB-II interface number to the associated VLAN ID.
VLA etsysVlanInterfaceVlanIndex	1.3.6.1.4.1.5624.1.2.22.2.1.1.1	VlanIndex	read-only	The VLAN ID of the VLAN that is represented by this MIB-II interface.
