CISCO Sub-Channel (subscreen of CISCO CIP Channel)

The investigation of CISCO CIPs may be continued by viewing the subchannels belonging to a particular channel by type.This MIB is accessed from the CISCO CIP Channel subscreen by simply clicking an Index number hyperlink.

The Cisco Sub-Channel Table has one subtable:

·         Events

The fields on the CIP Entry Table for a SubChannel are:

Index

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

Connections

Number of times a device was connected to the subchannel. For some devices, this value correlates with the number of start subchannels.

Cancels

Number of halt subchannels

Selective Resets

Number of selective resets.

System Resets

Number of system resets.

Device Errors

Number of device level errors.

Write Blocks Dropped

Number of times a block was received by the channel and a router buffer was not available so the block was discarded.

Last Sense Data

Last sense data sent to the channel by this device.

Last Sense Data Time

The time when the last sense data was sent to the channel by this device.

CU Busies

Number of control unit busies sent to the channel when this device was requested.

Cmd Retries

Number of times the subchannel went into command retry state. The sum of this value and the connections value gives the number of start subchannels.

Buffer Wait

Device state that occurs if the mainframe tries to write data to the CMCC when it has insufficient buffers for all of the write operation.
