Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is BIANCA-BRICK-X21-MIB?

BIANCA-BRICK-X21-MIB is a bintec elmeg BIANCA/BRICK enterprise MIB covering the router's X.21 serial WAN interface, used for leased-line or synchronous serial WAN connections. It exposes X.21 interface configuration and traffic/error statistics for that serial link. This is primarily a hardware/interface-status MIB — it lets an operator confirm the X.21 line's operational status and monitor traffic counters to catch a down or errored serial connection. No sample objects or module description are available in the provided material to confirm dependency on other MIBs, though X.21 interfaces are typically also represented in the standard IF-MIB. It's deployed on bintec elmeg BIANCA/BRICK routers using X.21 synchronous serial WAN links, common in older leased-line WAN deployments. Engineers can download the BIANCA-BRICK-X21-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BIANCA-BRICK-X21-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

No sample_objects were provided for this module, so no concrete object/table names from the input can ground a polling example. In general, an operator would expect to poll X.21 interface status and error counters to detect line-level faults or excessive errors on the serial WAN link. The precise object names would need to be confirmed from the actual MIB source.

x21	1.3.6.1.4.1.272.4.10
x21IfTable	1.3.6.1.4.1.272.4.10.1		not-accessible	The x21IfTable contains information relating to the interfaces found on the system. Each entry corresponds to a connected X21 interface. Entries can only be added or deleted by the system. Creating entries: Entries are created by the system only when a new X21 module is installed. Deleting entries: Entries are removed by the system after the appropriate X21 module is removed.
x21IfEntry	1.3.6.1.4.1.272.4.10.1.1		not-accessible
INT x21IfIndex	1.3.6.1.4.1.272.4.10.1.1.1	INTEGER	read-only	Unique index of the X21 interface.
INT x21IfL1State	1.3.6.1.4.1.272.4.10.1.1.2	INTEGER	read-only	The X21 physical layer state dn(1) physical layer is inactive; up(2) physical layer is active;
INT x21IfL1Mode	1.3.6.1.4.1.272.4.10.1.1.3	INTEGER	read-write	The physical layer (layer 1) mode. When configured as DCE(2) the X21 interface provides the clock.
INT x21IfIfLeads	1.3.6.1.4.1.272.4.10.1.1.4	INTEGER	read-write	The value of IfLeads has influence on the state of the physical layer (L1State). When configured as IfLeads=enabled(1), the state of the physical layer depends on the signals of the X.21 interface pins `Indication' and `Control'. When configured as IfLeads=disabled(2), the state of the physical layer stays always up.
INT x21IfSpeed	1.3.6.1.4.1.272.4.10.1.1.5	INTEGER	read-write	The X21 interface speed in bits per second. The range can be configured between 2Mbits and 2400 Bits per second.
INT x21IfL2Mode	1.3.6.1.4.1.272.4.10.1.1.6	INTEGER	read-write	The layer 2 mode. This value has influence on the HDLC address field (first byte of a HDCL frame). When configured as DTE(1) the address in a command frame is 0x01, when configured as DCE(2) it is 0x03. For response frames it is vice versa. When configured as AUTO(3), layer 2 is set to the same mode like L1Mode is set.
CTR x21IfSpeedReal	1.3.6.1.4.1.272.4.10.1.1.7	Counter	read-only	The measured X21 interface speed in bits per second.
CTR x21IfRxPackets	1.3.6.1.4.1.272.4.10.1.1.8	Counter	read-only	Count of received valid Frames.
CTR x21IfRxOctets	1.3.6.1.4.1.272.4.10.1.1.9	Counter	read-only	Count of received bytes.
CTR x21IfTxPackets	1.3.6.1.4.1.272.4.10.1.1.10	Counter	read-only	Count of transmitted valid Frames.
CTR x21IfTxOctets	1.3.6.1.4.1.272.4.10.1.1.11	Counter	read-only	Count of transmitted bytes.
CTR x21IfRxResets	1.3.6.1.4.1.272.4.10.1.1.12	Counter	read-only	Count of receiver resets. Under rare circumstances it might be necessary to reset the receiver to work properly.
CTR x21IfRxAborts	1.3.6.1.4.1.272.4.10.1.1.13	Counter	read-only	Count of receiver aborts. The sender of a frame can indicate a frame as aborted with a special Abort sequence.
CTR x21IfRxOverruns	1.3.6.1.4.1.272.4.10.1.1.14	Counter	read-only	Count of receiver overruns. If the X21 card is unable to grant sufficiently soon/often the bus, the 32-character RxFIFO may fill up. This leads to loss of data.
CTR x21IfRxCRCErrors	1.3.6.1.4.1.272.4.10.1.1.15	Counter	read-only	Count of corrupted frames. Errors due to interference on the X21 cable.
CTR x21IfRxGiantFrames	1.3.6.1.4.1.272.4.10.1.1.16	Counter	read-only	Count of received frames with illegal framesize. This can occur if a frame delimiter is destroyed.
CTR x21IfTxResets	1.3.6.1.4.1.272.4.10.1.1.17	Counter	read-only	Count of transmitter resets. Under rare circumstances it might be necessary to reset the transmitter to work properly.
CTR x21IfTxAborts	1.3.6.1.4.1.272.4.10.1.1.18	Counter	read-only	Count of transmitter aborts. While sending a frame it might be necessary to indicate this frame as aborted. In this case the receiver regards this frame as illegal.
CTR x21IfTxUnderruns	1.3.6.1.4.1.272.4.10.1.1.19	Counter	read-only	Count of transmitter underruns. The serial data for the X21 card is supplied too slowly.
CTR x21IfTxGiantFrames	1.3.6.1.4.1.272.4.10.1.1.20	Counter	read-only	Count of transmitted frames with illegal framesize. This can occur if an upper module creates packets with more than the maximum allowed packet size.
