Usage Guideline
•
This command is used to specify the type of information that is configured in ASCII text string format
and then inserted into the Option-82 Circuit ID suboption. Each parameter provided with this
command represents a different type of information.
•
Configuring the Circuit ID suboption in ASCII format allows up to five fields (types) of information
within the ASCII string. However, if the contents of all the fields combined exceeds 127 characters,
then the ASCII string is truncated.
•
Specifying at least one parameter with this command is required. If multiple parameters are selected,
then specifying one of the valid delimiter characters is also required.
•
The string parameter specifies user-defined information to insert into the Circuit ID ASCII field.
