What Is CTRON-WAN-IMUX-MIB?

CTRON-WAN-IMUX-MIB is a Cabletron (later Enterasys) enterprise MIB for managing WAN inverse multiplexers -- devices or line cards that bond multiple individual WAN links (such as multiple serial or T1 circuits) into a single logical high-bandwidth channel. It is intended to expose the configuration and status of the bonded channel and its constituent member links. This directly supports hardware status monitoring of WAN connectivity: tracking whether each member link within the bonded group is up or down reveals partial-capacity conditions where the logical channel is still functioning but at reduced bandwidth because one or more physical links have failed. It relies on the standard IF-MIB interface-index model for its member WAN interfaces while adding Cabletron-private inverse-multiplexing semantics on top. It is deployed on Cabletron/Enterasys WAN routers or multiplexer equipment bonding multiple serial WAN links into one logical circuit. Engineers can download the CTRON-WAN-IMUX-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CTRON-WAN-IMUX-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

Cabletron/Enterasys WAN routers and inverse-multiplexer equipment

Monitoring Examples

No specific object or table names were available for this module, so a concrete polling scenario cannot be grounded in real identifiers; conceptually, though, an administrator would check each bonded member link's up/down status and the resulting aggregate channel bandwidth to detect when one of several bonded WAN links has failed, reducing available throughput without dropping the logical channel entirely.

What Can Be Monitored

bonded channel status
individual member link up/down state
aggregate bonded channel bandwidth

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
ctWanMux	1.3.6.1.4.1.52.4.1.2.7.3.1
ctWANMuxGeneralGroup	1.3.6.1.4.1.52.4.1.2.7.3.1.1
INT ctWANMuxMaxNumGroups	1.3.6.1.4.1.52.4.1.2.7.3.1.1.1	INTEGER	read-only	Get the maximum number of Inverse Multiplexer groups allowed to be programmed for this device. This value is the number of physical WAN connections, divided by the minimum number of channels for a single mux to be operational (2). However, some devices may only support a single inverse multiplexer group.
INT ctWanMuxAdmin	1.3.6.1.4.1.52.4.1.2.7.3.1.1.2	INTEGER	read-write	Used to enable and disable the Inverse Multiplexer Application. This object is used to enable/disable Inverse Multiplexing for the entire device. Inverse Multiplexer Groups may be enabled/disabled independently using ctWanMuxGroupAdmin. This object must be set to enabled for any inverse multiplexing to occur on the device.
ctWanMuxGroupTable	1.3.6.1.4.1.52.4.1.2.7.3.1.2		not-accessible	Information describing the configured parameters of one of the Inverse Multiplexer groups.
ctWanMuxGroupEntry	1.3.6.1.4.1.52.4.1.2.7.3.1.2.1		not-accessible	A description of a single Inverse Multiplexer group entry.
INT ctWanMuxGroupId	1.3.6.1.4.1.52.4.1.2.7.3.1.2.1.1	INTEGER	read-only	A unique value identifying an element in a sequence of groups which belong to the WAN Inverse Multiplexer. This value ranges from 1 to the maximum number of programmable groups as described by ctWANMuxMaxNumGroups.
INT ctWanMuxGroupAdmin	1.3.6.1.4.1.52.4.1.2.7.3.1.2.1.2	INTEGER	read-write	Used to enable and disable an Inverse Multiplexer group which evenly distributes data traffic in a properly sequenced fashion, over two or more single channel Wide Area Network connections such as DS1, E1, DDS, or SYNC. Each of the single channel connections must be configured with an appropriate datalink protocol. A minimum of two channels, each assigned to it's own physical interface, is required before the Inverse Multiplexer group can be enabled.
INT ctWanMuxGroupNumChannels	1.3.6.1.4.1.52.4.1.2.7.3.1.2.1.3	INTEGER	read-only	Get the number of channels currently associated with this Inverse Multiplexer group. A minimum of two channels, each assigned to it's own physical interface, is required before the Inverse Multiplexer group can be enabled.
INT ctWanMuxGroupAddChannel	1.3.6.1.4.1.52.4.1.2.7.3.1.2.1.4	INTEGER	read-write	Add a channel to the channel list used by this Inverse Multiplexer group. Before a channel is added, the channel must be assigned a MIB II ifindex, and an acceptable Datalink Protocol. When this object is set, it is set with the ifindex value. This object is always read as a 1.
INT ctWanMuxGroupDelChannel	1.3.6.1.4.1.52.4.1.2.7.3.1.2.1.5	INTEGER	read-write	Delete a channel to the channel list used by this Inverse Multiplexer group. Before a channel is deleted, the channel must exist in the Inverse Multiplexer group's channel table. When this object is set, it is set with the ifindex value of the channel the user wishes to delete from the channel table. This object is always read as a 1.
ctWanMuxChannelTable	1.3.6.1.4.1.52.4.1.2.7.3.1.3		not-accessible	Table containing ifindex values, representing WAN channels, used by the Inverse Multiplexer. The table also contains statistics reported about each channel.
ctWanMuxChannelEntry	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1		not-accessible	A description of a single entry.
INT ctWanMuxChannelGroupId	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1.1	INTEGER	read-only	A unique value identifying an element in a sequence of groups which belong to the WAN Inverse Multiplexer. This value ranges from 1 to the maximum number of programmable groups as described by ctWANMuxMaxNumGroups.
INT ctWanMuxChannelId	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1.2	INTEGER	read-only	A unique value identifying an element in a sequence of member channel ifindex values which belong to a WAN Inverse Multiplexer group.
INT ctWanMuxChannelIfIndex	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1.3	INTEGER	read-only	Returns an ifindex associated with a WAN channel used for Inverse Multiplexing.
INT ctWanMuxChannelPhysNum	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1.4	INTEGER	read-only	Returns a unique physical connection identifier associated with this channel's physical WAN connection.
INT ctWanMuxChannelBwAvail	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1.5	INTEGER	read-only	Returns a value which represents the available bandwidth for transmitting data existing for the physical WAN connection associated with this channel. The value is represented in bits/sec.
INT ctWanMuxChannelByteCount	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1.6	INTEGER	read-only	Returns a value which represents a cumulative count of bytes transmitted out from this interface. The count includes any bytes transmitted across the physical medium, less physical medium framing.
INT ctWanMuxChannelStatus	1.3.6.1.4.1.52.4.1.2.7.3.1.3.1.7	INTEGER	read-only	Returns the current status of the channel associated with an inverse multiplexer group. The channel is active when the group admin status is enabled, and the channel is operational. The channel is inactive when either the group admin status is disabled, or the channel is not operational.
