5. Obtaining Failure Information
178
5.1.2 Collecting failure information by using the "dump" command
In the AX6700S, AX6600S, and AX6300S series, you can use operation commands to capture
memory dump information of the board or other components of the switch. The dump procedures
are described below.
(1) Capturing a memory dump when a communication failure occurs
When a communication failure occurs, execute all of the following commands to capture memory
dumps. The captured memory dump files are stored in
/usr/var/hardware (for versions prior to
Version 10.5, in
/dump0) in the system in which the commands were executed. You need to delete
the memory dump files after capturing the memory dumps.
In the AX6700S series:
1. In the active BCU, execute the dump bsu command for all the BSUs that are installed.
2. In the active BCU, execute the
dump nif command for all the ports that have failed.
Example:
The following procedure shows an example in which communication fails on port number 1
of NIF number 1 when the BSUs are installed on the BSU numbers 1 and 2.
1. Log in to the active BCU, and then execute the
dump command.
> dump bsu 1
Dump command accept.
>
11/01 17:43:42 E3 BSU BSU:1 25070700 1681:000000000000 BSU online dump
command executed.
2. After the above log information is displayed, execute the following dump command.
> dump bsu 2
Dump command accept.
>
11/01 18:10:42 E3 BSU BSU:2 25070700 1681:000000000000 BSU online dump
command executed.
3. After the above log information is displayed, execute the following dump command.
> dump nif 1
Dump command accept.
>
11/01 18:15:42 E3 NIF NIF:1 25000700 1240:000000000000 NIF online dump
command executed.
In the AX6600S series:
Information when the
configuration file
encounters an error
In administrator mode, execute the following commands to
copy two files to the home directory. Then transfer these
files.
cp /config/system.cnf system.cnf
cp /config/system.txt system.txt
When configuring a stack, copy the files of each member
switch to the master switch.
cp switch <switch no.> /config/system.cnf
system_
<switch no.>.cnf
cp switch
<switch no.> /config/system.txt
system_
<switch no.>.txt
• Use binary mode to transfer
these files with the
ftp
command.
• Delete the source files after
the transfer is completed.
