CISCO CIP Channel (subscreen of CiscoCIP)

The CISCO CIP Channel subscreen describes the MIB module for objects used to manage the Cisco Mainframe Channel Connection (CMCC) cards. The Channel table contains a list of objects pertaining to the channel or daughter board on the CMCC card.

The CISCO CIP Channel subscreen may be accessed from the CISCO CIP screen by simply clicking an Index number hyperlink.

The CISCO CIP Channel Table has two subtables:

·         Errors

·         Load and Statistics

Figure 85.  CISCO CIP Channel Table

 

The fields on the CIP Channel Table are:

Index

Indicates which daughter board or channel is being referenced for a particular Cisco Mainframe Channel Connection (CMCC) card.

Type

Indicates the channel path interface type.

Status

Indicates whether the microcode for the daughter board has been successfully loaded and is executing.

Signal

For ESCON, this field indicates if a light has been seen on the fiber and synchronization has been established.

For the Parallel Channel Adapter (PCA), which provides the Bus and Tag connection, this field indicates if Operational out has been sensed.

Online

For ESCON, this field indicates if a path has been established with at least one channel.

For PCA, this field indicates if the Parallel Channel Adapter (PCA) is online to the channel. That is, it responds to at least one device address.

 

ERRORS subtable

 

Type

Indicates the channel path interface type.

Incidents

Counts the number of times the ESCON Processor recovers from an internal error.

Code Violation

The number of recognized code-violation errors. A trap is issued when this number exceeds the bit error rate threshold for ESCON. The bit error rate threshold is set at 15-error burst within a 5-minute period. An error burst is the time period of 1.5 seconds plus or minus 0.05 seconds during which one or more code violation errors occur.

Signal or
Sync Loss

The number of link failures recognized as a result of a loss of signal or loss of synchronization that persisted longer than the link interval duration, the link interval duration is one second with a tolerance of +1.5 seconds and -0 seconds.

NOSs

The number of link failures recognized as a result of the not-operational sequence (NOS).

Sequence Timeouts

The number of link failures recognized as a result of a connection recovery timeout or response timeout occurring while in transmit OLS state.

 

Invalid Sequences

The number of link failures recognized as a result of an invalid sequence for Link-Level-Facility State. Either a UD or UDR sequence was recognized while in wait-for-offline-sequence state.

Trap Cause

Indicates the reason for the last link failure.

·         liStatus indicates that the daughter board status has changed.

·         liImplicitIncident indicates that a condition that may cause the recognition of a link incident in the attached node has been recognized.

·         liBERthreshold indicates that the code violation error rate exceeded the threshold.

·         liSignalOrSyncLoss indicates a loss of signal or loss of synchronization that persisted longer than the link interval duration.

·         liNotOperationalSequence indicates the recognition of not-operational sequence, usually due to the operator taking the channel offline.

·         liSequenceTimeout indicates a connection recovery timeout or response timeout occurring while in transmit OLS state.

·         linvalidSequence indicates a UD or UDR sequence was recognized while in wait-for-offline-sequence state.

 

LOAD AND STATISTICS subtable

 

Type

Indicates the channel path interface type.

Last Stat

This object indicates how old the statistics are.

Next Stat

This object indicates when statistics will next be read.

Channel Load 1 Min

The average, over the last minute, of the percentage of time the channel adapter was busy communicating to a host.

Channel Load 5 Min

The average, over the last 5 minutes, of the percentage of time the channel adapter was busy communicating to a host.

Channel Load 60 Min

The average, over the last 60 minutes, of the percentage of time the channel adapter was busy communicating to a host.
