Re: Explanation of SYS-4-P2_WARN: 1/Astro (module_number/Astro_r

This error message indicates the Supervisor has lost control communication to an ASIC on the 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 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 may be a faulty Supervisor component.

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 indicating a different Supervisor Component Failure. Generally, this failure is

accompanied by both the Astro Timeout Error Message and BlockTXQueue and

BlockedGigaport Error Message
