Cat4006 Error Message

Do you know what the following error message seen on a Cat4006 means:-

%SYS-4-P2_WARN: 1/Astro(4/2) - timeout occurred

The error decoder does not recognise the error.

Port 4/2 is is one of four ports (4/1-2) in an etherchannel to a Cat6509.

Re: Cat4006 Error Message

ASTRO (short for ASTROdome) is a 8 Fast Ethernet to Gigabit Ethernet stub. It is basically multiplexer of 8 10/100 ports into 1GB connection to the backplane and vice-versa. 4/2 points to module 4 Astro 2.Issuing the command dump 1 will provide additional information about the Astro

A previous thread on this should help

Re: Cat4006 Error Message

Kevin,

Have a look at the following -

http://www.cisco.com/warp/public/473/34.shtml

It describes the Astro errors. You may also want to check the logs for a high number of CRC errors/ Packet drops...

Re: Cat4006 Error Message

1. %SYS-4-P2_WARN: Host [mac addr] is flapping between port [dec/dec] and port [dec/dec]

The above message indicates that your Catalyst 4000 switch has learned a MAC address that already exists in its CAM table on a port other than the original one.

Recommended Action: What you need to do is to track down how this MAC address was learned from both ports.

Step 1: Consider port the first port. Issue the show cam dynamic [port] command. If you see the MAC address 00:50:0f:20:08:00 coming out in the list of the MAC addresses learned on this port, try to see if this is a single host that is connected or if there are multiple hosts registered on that port.

Step 2: If it is a single host that is connected, check the other port that is registered and see if the host is dually attached to the switch. If however, the host has connections to other devices that can eventually lead back into this switch, try to track down the intermediate devices that are in between.

Note: The best way to achieve this (assuming that they are Cisco devices) is to use the output of the command show cdp neighbors detail.
