olModSummaryInfo

Module: CHIPCOMMIB

OID (symbolic): CHIPCOMMIB::olModSummaryInfo

OID (numeric): 1.3.6.1.4.1.49.2.3.1.4.5.1.2

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: A summary of all information relating to this module in

condensed format.  The condensed format is only as large

as needed to hence the largest value which usually is one

octet.  The TCP port for the terminal server, however,

uses 4 octets.



The summary consists of a header, a module portion, a port

portion, and a trunk portion.  Each portion consists of

generic information and module specific information.

For example, the module information consists of the

olModTable entry for this slot and the olSpecMods module

table information for this module type for this slot.





---------------------------------------------------

The header consists of the following octets:

        Version of structure : 1



        Number of octets in generic module

        Number of octets in specific module

        Number of octets in generic port

        Number of octets in specific port

        Number of octets in generic trunk

        Number of octets in specific trunk



The format of the data portion is as follows:



        Some of the olModTable:

                olModType

                olModClass

                olModDescr

                olModVersion

                olModNetwork

                olModNetworkType

                olModStatus



                olModNumPorts

                olModNumTrunks





        olSpecMods module table (for this module)

                Not including slot number.



For each port:

        Some of the olPortTable:

                olPortType

                olPortConnector

                olPortStatus

                olPortAdminState

                olPortNetwork

                olPortNetworkType

                olPortAlertFilter



        olSpecMods port table (for this port's module)

                Not including slot and port number.



For each trunk:

        Some of the olTrunkTable:

                olTrunkType

                olTrunkConnector

                olTrunkStatus

                olTrunkAdminState

                olTrunkWrapState

                olTrunkNeighbor





        olSpecMods trunk table (for this trunk's module)

                Not including slot and trunk number.



---------------------------------------------------

Version 2 of the summary structure:



Version 2 is returned only when there is a possibility

of multiple modules per slot.  This is a function of

the platform (concentrator).  The ONcore platform

is an example of this.  ONline modules in the ONcore

platform will still be represented by version 1 structure.



Version 2 is an array of version 1 structures,



Version: 2



Maximum number of v1 structures = 8.

Number of v1 structures to follow => max of 8.

Reserved octet = 0.



2 octets each describing the length of v1 summaries:

        Number of octets in summary #1.

        Number of octets in summary #2.

        Number of octets in summary #3.

        Number of octets in summary #4.

        Number of octets in summary #5.

        Number of octets in summary #6.

        Number of octets in summary #7.

        Number of octets in summary #8.



Array of Version 1 structures.



For example, there are 3 modules in slot 5, in subslot

locations 1, 3 and 8.

        (21 + N(1)) + N(3)



        (21 + N(1)) + N(3)

        to              Version 1 summary for module in sslot 8



        ((21 + N(1)) + N(3)) + N(8)



        21 to 21 + N(1) Version 1 summary for module in sslot 1

What is olModSummaryInfo?

Provides a condensed summary of all information about the module in a compact binary format, packing details like status and terminal server TCP port into as few octets as possible.
