How to Read System Messages

System messages begin with a percent (%) and are structured as follows: The text in bold are required elements of the system message, the text in italics are optional elements of the system message.

%FACILITY-SEVERITY-MNEMONIC: Message-text
 
   

FACILITY is a code consisting of two or more uppercase letters that inciate the facility to which the message refers. A facility can be a hardware device, a protocol, or a module of the system software. You can see a complete list of mainline facility codes for Cisco IOS Release 12.3 on Cisco.com. Go to this URL:

http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/index.html

SEVERITY is a single-digit code from 0 to 7 that reflects the severity of the condition. The lower the number, the more serious the situation. Table C-1 lists the severity levels.

Table C-1 Error Message Severity Levels

Level
Description

0 - emergency

System unusable

1 - alert

Immediate action needed

2 - critical

Critical condition

3 - error

Error condition

4 - warning

Warning condition

5 - notification

Normal but significant condition

6 - informational

Informational message only

7 - debugging

Appears during debugging only


MNEMONIC is a code that uniquely identifies the error message.

Variable information is indicated in brackets, for example [mac-address] indicates a the mac address of a device, [characters] indicates a character string, and [number] indicates a numeric value.

Message Traceback Reports

Some messages describe internal errors and contain traceback reports. This information is very important and should be included when you rerport a problem to your technical support representative.

The folloiwng sample message includes traceback information:

-Process= "Exec", level= 0, pid= 17
-Traceback= 1A82 1AB4 6378 A072 1054 1860

Association Management Messages

Error Message    DOT11-3-BADSTATE: [mac-address] [characters] --> [characters]

Explanation    802.11 association and management uses a table-driven state machine to keep track and transition an association through various states.

Error Message    DOT11-2-RADIO_HW_RESET: Radio subsystem is undergoing hardware reset 
to recover from problem

Explanation    An unrecoverable error occurred that could not be resolved by a soft reset.

Recommended Action    None.

Error Message    DOT11-4-MAXRETRIES: Packet to client [characters] reached max retries, 
removing the client

Explanation    This error message indicates that the access point attempts to poll the client a certain number of times, but does not receive a response. Therefore, the client is removed from the association table. This issue is commonly seen when the client and access point are attempting to communicate in a noisy RF environment.

Recommended Action    To resolve this issue, run a carrier busy test on the access point to determine if there is excessive noise in the radio channel spectrum. Attempt to alleviate any unwanted noise.

If there are several access points in the same area, there might be overlapping the channel signals or possibly other wireless device in the area.

from the station [mac-address] on the packet (TSC=0x%11x) encrypted and protected 
by [key] key."

Explanation    TKIP Michael MIC failure was detected from the indicated station on a unicast frame decrypted locally with the indicated pairwise key.

Recommended Action    A failure of the Michael MIC in a packet usually indicates an active attack on your network. Search for and remove potential rogue devices from your wireless LAN.

detected within [number] seconds on [interface] interface. The interface will be 
put on MIC failure hold state for next [number] seconds

Explanation    Two TKIP Michael MIC failures were detected within the indicated time on the indicated interface. Because this usually indicates an active attack on your network, the interface will be put on hold for the indicated time. During this hold time, stations using TKIP ciphers are disassociated and cannot reassociate until the hold time ends. At the end of the hold time, the interface operates normally.

Recommended Action    MIC failures usually indicate an active attack on your network. Search for and remove potential rogue devices from your wireless LAN. If this is a false alarm and the interface should not be on hold this long, use the countermeasure tkip hold-time command to adjust the hold time.
