Enabling serial port snoop

Specify parameters (including the snoop string) for enabling a serial port (system port) snoop.

You can disable or enable a snoop operation on a system port. When enabled, data received on the selected port is examined, or snooped, as it arrives. You can also specify the snoop string, a particular sequence of bytes that resets the service processor if detected. The system port S1 serves as a "catchall" reset device.

Note: Each system port is disabled when a Hardware Management Console (HMC) is attached to the server, and the server is booted beyond the service processor standby state.

To perform this operation, you must have one of the following authority levels:

General
Administrator
Authorized service provider

Note: This task is not available on the 9080-MHE, 9080-MME, 9119-MHE, and 9119-MME systems.

To view and change the current Serial Port Snoop settings, complete the following steps:

On the ASMI Welcome pane, specify your user ID and password, and click Log In.
In the navigation area, expand System Service Aids and select Serial Port Snoop.
Disable or enable snooping on system port S1. The default is Disabled.
Enter the desired snoop string, up to 32 bytes, into the Snoop string field. The current value displayed is the default. Ensure that the string is not a commonly used string. A mixed-case string is recommended.
Click Update snoop parameters to update the service processor with the selected values.
Note: After the snoop operation is correctly configured, at any point after the system is booted, the system uses the service processor reboot policy to restart whenever the reset string is typed on an ASCII terminal attached to system port S1.
