• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.
• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, 

uppercase letters and numerals to convert a binary X.509 certificate into a printable form.

• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital 

signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The 
private key is not included. The NWA/WAC currently allows the importation of a PKS#7 file that 
contains a single certificate. 

• 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/WAC. 

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/WAC 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/WAC exit sub command mode.

• Include write commands in your scripts. Otherwise the changes will be lost when the NWA/WAC 

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/WAC 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.
