Querying the CPU/DSP Status

This describes how to query the status of the CPUs and how to query the status of the DSP unit in the GDPUC/GDPUX/GDPUP.

Table 1 describes the CPU/DSP states that can be queried on the LMT.

**Table 1** Board status
Parameter	Meaning	Value Range
Admin state	Indicating whether the current board can provide services or not	Lock: The current board cannot provide services. Unlock: The current board can provide services, but whether it actually provides services depends on other states, such as operation state and standby state. Shutdown: New services cannot access the current board, but the existing services on the board continue. NOTE: After all the services on the board exit, the board enters Shutdown automatically.
Operation state	Indicating whether the current board can be operated or not	Enable: The current board can be operated. Disable: The current board cannot be operated.
Standby state	Indicating whether the current board works in active mode or standby mode	Active: The current board works in active mode. Standby: The current board works in standby mode. Unassigned: The current board is not in active/standby mode. Invalid: The current board is not ready.
Available state	indicating more information about the board usage state	Normal: The current board is running properly. Fault: The current board is faulty. Uninstalled: The current board is not in position. Inconsistent: The status information about the current board is inconsistent with the configuration information about the slot. Power off: The current board is powered off.

The method of querying CPU state is the same as that of querying DSP state. This topic takes querying the CPU state as an example.

Through GUI
1. On the LMT, choose BSC Maintenance > Maintain Device > Query CPU/DSP State.
2. Select CPU in the Query Type area, set parameters in the Location area, and then click Query. The results are displayed, as shown in Figure 1.

Through MML
1. You can run the following commands on the Local Maintenance Terminal to query the CPU/DSP status.
  - Run the DSP CPUSTAT to query the CPU status.
  - Run the DSP DSPSTAT to query the DSP status.
