Relative numbering
Relative numbering specifies a user interface or a group of user interfaces of a specific type. The number
is valid only when used under that type of user interface. It is invalid when used under other types of user
interfaces.
Relative numbering numbers a user interface in the form of “user interface type + number”. The rules of
relative numbering are as follows:
• Console ports are numbered from 0 in the ascending order, with a step of 1.
• AUX ports are numbered from 0 in the ascending order, with a step of 1.
• VTYs are numbered from 0 in the ascending order, with a step of 1.

Attributes
A serial interface contains the following key attributes:
• Transmission rate: Number of bits that the device transmits to the terminal per second. It measures
the transmission speed. Typically a higher transmission rate is used between closer distances for
communication.
• Data bits: Number of bits representing one character. The setting depends on the contexts to be
transmitted, For example, you can set it to 7 if standard ASCII characters are to be sent; set it to 8
if extended ASCII characters are to be sent.
