Meaning of the error message SYS-4-P2_WARN: 1/Astro(module_number/Astro_reference) – timeoutoccurred

What is the meaning and possible causes for the following error messages:

SYS-4-P2_WARN: 1/Astro(module_number/Astro_reference) – timeoutoccurred

SYS-4-P2_WARN: 1/Astro(module_number/Astro_reference) – timeout is persisting


Re: Meaning of the error message SYS-4-P2_WARN: 1/Astro(module_n

This error message was added to software versions 6.2.3 and 6.3.1 or higher. Previous software versions will not report this error message.

This error message indicates the Supervisor has lost control (inband) communication to

the Astro ASIC on 10/100 Line Cards. There are multiple possible causes for this loss of communication:

1) Layer 2 Loop or Broadcast Storm that results in high traffic load that causes loss of control traffic. Control traffic takes the same interconnect path

as data traffic.

2) If the module number and Astro Reference are consistent and a layer 2 loop is not occuring, the problem is possibly a faulty hardware component on either the Supervisor or Line Card. Relocating the module in a different slot in the chassis and determine whether error message follows the module should determine whether the faulty hardware is with the Supervisor or Line Card.

3) If the module number and Astro reference in respect to the error message is alternating modules and Astros, then the error message could be a different type of hardware failure on the Supervisor. Generally, an this type of failure is accompanied by both the Astro Timeout Error Message and BlockTXQueue and

BlockedGigaport Error Messages.
