Cisco WAN Module MIB File

This chapter describes the MIB objects to configure connection specific parameters and statistics information in a Service Module (SM). SM is defined as any module, which provides services such as ATM, Frame Relay, or Voice in a Wide Area Network (WAN) switch.

Cisco WAN Module Textual Convention

The names of the textual conventions are specified in the object syntax.

One MIB object is listed in Table 13-1.

Note Textual conventions do not contain object identifiers.

Name Description Syntax Default Value

StatisticsLevel

Configures the statistics level for the service module. The statistic level on a module dictates the type and amount of statistics that are collected.

The a predefined set of statistics are associated with each level and are enabled when a level is set. Also, setting the statistics level to N enables counters that are associated with levels N-1 through 1.

The following are the valid values:

notApplicable(0)—Specifies the statistics level is not applicable.

levelOne(1)—Enables the level one counters.

levelTwo(2)—Enables level two and level one counters.

levelThree(3)—Enables level one, level two, and level three counters.

StatisticsLevel	Configures the statistics level for the service module. The statistic level on a module dictates the type and amount of statistics that are collected. The a predefined set of statistics are associated with each level and are enabled when a level is set. Also, setting the statistics level to `N` enables counters that are associated with levels `N-1` through `1`. The following are the valid values: `notApplicable(0)`—Specifies the statistics level is not applicable. `levelOne(1)`—Enables the level one counters. `levelTwo(2)`—Enables level two and level one counters. `levelThree(3)`—Enables level one, level two, and level three counters. Status: current	INTEGER {notApplicable(0), levelOne(1), levelTwo(2), levelThree(3 }	none

Name Syntax Description Default Value

cwmConfigTable

SEQUENCE OF CwmConfigEntry

Contains the objects required for configuring module specific parameters. These parameters are related to the hardware specific parameters, which can effect the ATM Connection characteristics.

Max-Access: not-accessible

Status: current

none

cwmConfigEntry

CwmConfigEntry

Provides an entry that contains information for each module.

Max-Access: not-accessible

Status: current

The index is cwmIndex.

none

cwmIndex

Unsigned32 (1..2147483647)

Specifies the value that corresponds to the slot number where the module resides. However, system wide uniqueness is the only true requirement.

Max-Access: not-accessible

Status: current

none

cwmIngressSCT
FileId

Unsigned32 (0..255)

Defines the file ID of the Service Class Template (SCT) file. The SCT holds the connection specific parameters for this module in the ingress direction, for example, network to switch.

The SCT provides a means for inferring extended parameters, which are generally platform-specific, from the set of standard ATM protocol parameters passed in Virtual Switch Interface (VSI) connection setup primitives. A set of Service Templates are available in a nonvolatile storage, and is downloaded onto each SM on power up.

SCT contains the following two classes of data:

One class consists of parameters necessary to establish a Virtual Connection, for example, per-VC, and includes entries such as Usage Parameter Control (UPC) actions, various bandwidth-related items, per-VC thresholds, and some hardware-specific items.

The second class of data items includes those necessary to configure the associated Class-of-Service Buffers that provide the Quality of Service (QoS) support.

Max-Access: read-write

Status: current

none

cwmIngressSCT
FileName

DisplayString

Contains the SCT filename. Write access is not required. The filename has the cwmIngressSCTFileId value as the suffix. For example, the value SCT.INGR.13 for this object indicates 13 is the value of cwmIngressSCTFileId.

Max-Access: read-write

Status: current

none

cwmAutoLineDiagEnable

INTEGER { enable(1), disable(2) }

Enables and disables automatic diagnostic feature of physical lines on module. In case of a line alarm, enabling this feature temporarily suspends traffic in both directions and starts local loopback testing. Disabling this feature will not effect the traffic in one direction while another direction is in alarm.

Max-Access: read-write

cwmStatConfig
Table

SEQUENCE OF CwmStatConfigEntry

Specifies the objects that are required for configuring module statistic collection-related parameters. The statistics related to the interfaces and ATM Connections are stored in a file. The statistics file is uploaded by the Network Manager System (NMS) applications using file transfer protocols, for example Trivial File Transfer Protocol (TFTP) or File Transfer Protocol (FTP).

While current interval of data is being collected in memory, the previous interval of data is uploaded by NMS. Each interval's data can overwrite the previous interval's data in the statistic file after the interval is over.

cwmStatConfig
Entry

CwmStatConfigEntry

cwmStatBucket
Interval

INTEGER { five(5), ten(10), fifteen(15), twenty(20), thirty(30), sixty(60) }
