TERMS AND DEFINITIONS
This document defines the following terms:
Management Information Base (MIB) — the specification of information in a manner that allows standard access through a network management protocol.
REQUiREMENTS
This section defines the mandatory syntax of the SCTE-HM S-HE-OPTICAL-S WITCHMIB. It follows the IETF Simple Network Management Protocol (SNMP) for defining managed objects. The syntax is given below.

DESCRIPTION
“The MIB module for the HMS HE Optical Switch module
entitles.
This MIB module is for representing optical switch equipment present in the headend (or indoor) and is supported by a SNMP agent.
This MIB is limited in its scope and intended to describe an A-B (2 input and I output) or a crossbar optical switch. Up to 2 optical inputs and 2 outputs are supported. Any devices with more than 2 optical inputs or outputs shall be covered by another MIB.
This M1B does not intend to dictate all of the nuances involved in changing control settings (automatic or manual mode, changing switch controls in each possible mode combination). The most common desired behaviors are noted but specific switch operation and behavior are left to the optical switch vendors.
Not all control enumerations must be supported. This is noted in the variables that have optional enumerations.
Refer to the associated notes for information on what SNMP responses should be returned for unsupported enumerations.”
— Every optical switch is modeled by the tables presented
— in this MIB module. These tables extend the entPhysicalTable
— according to RFC 2737. The extension index entPhysicallndex uniquely
— identities the optical switch.
— Every optical switch is also modeled by the following tables:
— entPhysicalEntry – I row; (defined in document: RFC2737)
— heCommonEntry – 1 row. (defined in document: HMS 111)
— Every optical switch module will have its alarms modeled by the table:
— propertyEntry – x rows; (defined in document: HMSO26)
— (where x is the nos. of alarmable analog properties supported
— by the optical switch)
discretePropertyEntry – y rows; (defined in document: HMSO26) (where y is the nos. of alarmable digital properties supported by
— the optical switch)
— Every optical switch module will have a list of currently active
— alarms modeled by the table:
— currentAlarmEntry – z rows; (defined in document: HMSO26)
— (where z is the nos. of current active alarms in the optical
– – switch)
— Thus, an A-B optical switch (2 optical inputs and one optical output)
— will be represented by one row in entPhysicalTable, one row in
— heCommonTable. one row in heOpSwitchUnilTable, two rows in
— hcOpSwitchlnputTable and one row in heOpSwitchOutputTable.
— Additionally, a crossbar optical switch (2 inputs and 2 outputs)
— will be represented by one row in entPhysicalTable, one row in
— heCommonTable, one row in hcOpSwitchUniiTable, two rows
— in heOpSwitchlnputTable and two rows in heOpSwitchOutputTable.
— Correlation of outputs and inputs are indicated by the heOpSwitchState
— variable. Correlation of physical inputs and outputs to
— heOpSwitchlnputTable and heOpSwitchOutputTables rows is indicated
— by the heOpSwitchlnpurDescription and heOpSwitchOutputDescription
— variables.
