7. UNDERSTANDING COMMAND-LINE SYNTAX
The logical structure of the configuration commands given using the CLI is
referred to as syntax.
The configuration command syntax used by Cisco devices is simple. The
command-line syntax can be used to issue one command, or to issue
multiple commands within a single command entry, before pressing the
Enter key.
If multiple commands are made within a single command entry, all
commands must be separated by spaces.
For demonstration, here are typical examples that show ways in which a
radio transceiver’s Ethernet parameters can be configured.
To show the current configuration for a specific Ethernet port, you would
enter the following command:
ethernet port eth 1
To configure the data transfer speed and duplex mode for a specific
Ethernet port, you would make the needed choices based on:
• The specifications given in the network design document, and
• The characteristics of the Cisco device.
As a typical example, an FM3500 Endo radio transceiver has the following
features:
• Two RJ-45 Ethernet ports, numbered 1 and 2.
• A choice of two duplex modes (half and full).
Based on this information, if you wanted to set Ethernet port 2 of the
FM3500 Endo to transmit and receive data in full duplex mode, you would
enter the following command:
ethernet port eth 2 duplex full
