• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase
letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable
form.
• Binary PKCS#12: This is a format for transferring public key and private key certificates.The
private key in a PKCS #12 file is within a password-encrypted envelope. The file's password is not
connected to your certificate's public or private passwords. Exporting a PKCS #12 file creates this
and you must provide it to decrypt the contents when you import the file into the NWA.
Note: Be careful not to convert a binary file to text during the transfer process. It is easy
for this to occur since many programs use text files by default.
I can only see newer logs. Older logs are missing.
When a log reaches the maximum number of log messages, new log messages automatically
overwrite existing log messages, starting with the oldest existing log message first.
The commands in my configuration file or shell script are not working properly.
• In a configuration file or shell script, use "#" or "!" as the first character of a command line to
have the NWA treat the line as a comment.
• Your configuration files or shell scripts can use "exit" or a command line consisting of a single "!"
to have the NWA exit sub command mode.
• Include write commands in your scripts. Otherwise the changes will be lost when the NWA
restarts. You could use multiple write commands in a long script.
Note: "exit" or "!'" must follow sub commands if it is to make the NWA exit sub command
mode.
I cannot get the firmware uploaded using the commands.
The Web Configurator is the recommended method for uploading firmware. You only need to use
the command line interface if you need to recover the firmware. See the CLI Reference Guide for
how to determine if you need to recover the firmware and how to recover it.
Wireless clients are not being load balanced among my APs.
• Make sure that all the APs used by the wireless clients in question share the same SSID, security,
and radio settings.
• Make sure that all the APs are in the same broadcast domain.
• Make sure that the wireless clients are in range of the other APs; if they are only in range of a
single AP, then load balancing may not be as effective.
