cmBad

Module: CISCO-MODEM-MGMT-MIB

OID (symbolic): CISCO-MODEM-MGMT-MIB::cmBad

OID (numeric): 1.3.6.1.4.1.9.9.47.1.3.2.1.6

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: This object can hold modem out of service and marks the modem as suspected or proven to be bad. During the router start-up initialization sequence, modem back-to-back tests will test modems and mark those modems failing tests as bad modems. The management entity also can use this command to lock out the suspicious modem or unlock the modem to do further debugging or test. This command will be used accompanied with cmholdReset command to put modem out of service. This command doesn't do the reset. For a normally good modem, it can start handling calls after it exits from modem reset mode. For a bad modem, it cannot start handling calls after it exits from modem reset mode. The manager needs to take modem out of bad modem mode in order to handle calls.

This object is only valid when cmState is onHook or busiedOut. The value of true(1) indicates the modem is suspected to be bad and its state is set to bad. The value of false(2) indicates the modem has not been suspected to be bad or has been re-marked as good.

What is cmBad?

A read-write flag used to mark a modem as suspected or confirmed bad and take it out of service, such as after failing router start-up diagnostic tests.
