The MIB module for BSC.
Overview of BSC MIB
MIB description
The BSC MIB provides the configuration and operational information on Cisco's Binary Synchronous Communications implementation. The following entities are managed: 1) BSC ports (serial interfaces) 2) BSC Control Units (stations on a port)
The BSC ports are identified by the interface index, and additional information about this interface can be obtained from the Cisco Serial Interface MIB. The BSC Control Units are identified by the Control Unit address; this is the address used by BSTUN to route the BSC traffic - it is therefore equivalent to the bstunRouteStationAddress in the bstunRouteTable MIB.
InterfaceIndexA unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization.

The router's DLC role to the attached node. If the bscPortRole is primary, this implies that the port is connected to a remote secondary device. If the role is generic, this indicates that the port will be running framed bisynchronous frames with an unknown protocol. If this object does not have the value 'contention' then bscPortVirtualAddress will not be instantiated. If this object does not have the value 'dialContention' then bscPortContentionDialTimeout will not be instantiated.
bscPortCodeSet
1.3.6.1.4.1.9.9.36.1.1.1.1.2
INTEGER1 = ebcdic2 = ascii · Integer32
The code set used for the line controls.
bscPortPause
1.3.6.1.4.1.9.9.36.1.1.1.1.3
INTEGER (0..255) · Integer32
For primary, it is the minimum time to be taken for a cycle round the active poll table; if this time has not elapsed when the bottom of the poll table is reached, then polling will pause until this timer expires. A value of zero means there will be no pause between cycles round the poll table. For secondary, the pause time out is the delay taken before sending a response to a poll when it has no data frame to send. The units are tenths of a second. The default is 10 (1 second).
bscPortServlim
1.3.6.1.4.1.9.9.36.1.1.1.1.4
INTEGER (1..50) · Integer32
This parameter is valid for primary only. It is the number of times the active poll table will be cycled before a non-responding control unit will be polled. The default is 3.
bscPortPollTimeout
1.3.6.1.4.1.9.9.36.1.1.1.1.5
INTEGER (1..100) · Integer32
This parameter is valid for primary only. It is the time that the primary will wait for a response to a poll or select. The units are tenths of a second. The default is 10 (1 second).
bscPortRecoveryRetries
1.3.6.1.4.1.9.9.36.1.1.1.1.6
INTEGER (1..100) · Integer32
This is the number of times that a recovery sequence will be retried before the connection is considered to have failed. The default is 5.
bscPortUnknownControlUnitsReceived
1.3.6.1.4.1.9.9.36.1.1.1.1.7
Counter32
Count of frames received from the serial interface with an unsupported control unit address. If this value is non-zero it indicates a problem in the configuration.
bscPortSoftErrors
1.3.6.1.4.1.9.9.36.1.1.1.1.8
Counter32
Count of soft errors; these are errors which have been recovered. This includes CRC errors received, frames which were retransmitted for any reason (NAK received or the wrong ACK received), etc. This count is a measure of the quality of the port/line, but should be considered in relation to the amount of traffic on the port (frames or bytes sent and received). This count includes all control unit soft errors on this port, plus errors which were not for a specific control unit.
bscPortHardErrors
1.3.6.1.4.1.9.9.36.1.1.1.1.9
Counter32
Count of hard errors; these are errors which have not been recovered after bscPortRecoveryRetries number of retries, and therefore the connection has been terminated. These errors could be caused by a hardware error in the line or in the remote device; or possibly the bscPortRecoveryRetries value is set too low for the quality of the line. This count includes all control unit hard errors on this port, plus errors which were not for a specific control unit.
bscPortProtocolViolations
1.3.6.1.4.1.9.9.36.1.1.1.1.10
Counter32
Count of protocol violations. This counter is incremented when an unexpected BSC Data Link Control character is received from the remote device; that is, the control character is invalid in the current state of the local BSC FSM. This indicates that there is an incompatibility between the two implementations of the BSC protocol. This count includes all control unit protocol violations on this port, plus errors which were not for a specific control unit.
bscPortHostTimeout
1.3.6.1.4.1.9.9.36.1.1.1.1.11
Integer32 (30..3000) · deciseconds
This parameter is valid for interfaces configured secondary which additionally are running local-acknowledgement. If the configuration does not match the value will be shown as zero. It is the time the interface will wait for a poll from the host before putting the CU on the inactive list. The default is 60 seconds.
bscPortSpecPoll
1.3.6.1.4.1.9.9.36.1.1.1.1.12
TruthValue1 = true2 = falseRepresents a boolean value. · Integer32
This parameter is valid for primary, local-acknowledgement interfaces only. It is set to TRUE when the interface is configured to treat specific polls as general polls. If the configuration cannot support this value, it will be set to FALSE. The default is FALSE.
bscPortVirtualAddress
1.3.6.1.4.1.9.9.36.1.1.1.1.13
Integer32 (1..254)
This parameter is valid for contention only. It is the address to be used for this interface when the remote peer router is being used as a concentrator. The default is 01.
bscPortContentionDialTimeout
1.3.6.1.4.1.9.9.36.1.1.1.1.14
