Hello,

I agree here the result of error message decoder

3. %SYS-4-P2_WARN: 1/Astro(mod/port) The switch is generating %SYS-4-P2_WARN: 1/Astro(6/6)... messages.

This error message indicates that the Supervisor Engine has lost communication to a component on a line card. The Supervisor Engine keeps track of any timeouts that are associated with this communication.

Recommended Action: There are many possible causes associated with this condition. For more information on this error message and possible causes, refer to http://www.cisco.com/en/US/products/hw/switches/ps663/products_tech_note09186a00801c9221.shtml

Hope to help

Giuseppe

A lot of times this is caused when someone introduces a loop on the switch and ties up the supervisor so long that it can't talk to the linecards . Seeing its on more than 1 card I would suspect that . Check for loops . Do a show proc cpu , usually cpu will also be very high if this is happening and telnet access to switch will be slow . Doa show cdp nei and see if the switch sees "itself" on more than 1 port indicating a looped port . If you see this shutdown one of the ports which will break the loop and normalize the cpu . That being said it could still be a supervisor .
