Configuration Files Overview Working With Configuration Files
page 6-8 OmniSwitch 6600 Family Switch Management Guide March 2005
Setting the Error File Limit
The number of files ending with the .err extension present in the switch’s /flash directory is set with the
configuration error-file limit command. You can set the switch to allow up to 25 error files in the /flash
directory. Once the error file limit has been reached, the next error file generated will cause the error file
with the oldest time stamp to be deleted. The following command sets the error file limit to 5 files.
-> configuration error-file limit 5
If you need to save files with the .err extension, you can either rename them so they no longer end with the
.err extension or you may move them to another directory.
Note. The default error file limit is one file. Unless you set the error file limit to a higher number, any
subsequent error file will cause any existing error file to be overwritten.
Syntax Checking
The configuration syntax check command is used to detect potential syntax errors contained in a
configuration file before it is applied to the switch. It is recommended that you check all configuration
files for syntax errors before applying them to your switch.
To run a syntax check on a configuration file, use the configuration syntax check command.
For example:
-> configuration syntax check asc.1.snap
Errors: 3
Log file name: check asc.1.snap.1.err
In this example, the proposed asc.1.snap configuration file contains three errors. As with the
configuration apply command, an error file (.err) is automatically generated by the switch whenever
an error is detected. By default, this file is placed in the root /flash directory.
Note. The syntax, mac alloc, is automatically included in many snapshot files (e.g., configuration
snapshot all). All mac alloc-related syntax is valid during switch boot up only (i.e., it cannot be applied
while the switch is in run-time operation). Because snapshot files are commonly used as configuration
files, syntax checks may detect mac alloc syntax and issue an error (along with a generated .err file).
This is a valid switch function and does not represent a significant problem. If a mac alloc-related error is
the only error detected, simply remove the syntax using a text editor, then re-check the file using the
configuration syntax check command.
If a configuration file is located in another directory, be sure to specify the full path. For example:
-> configuration syntax check /flash/working/asc.1.snap
Viewing Generated Error File Contents
For error details, you can view the contents of a generated error file. To view the contents of an error file,
use the more command. For example:
-> more asc.1.snap.1.err
