This section includes these chapters: "Using the Command Line Interface" on page 112 "General Commands" on page 118 "System Management Commands" on page 122 "System Logging Commands" on page 137 "System Clock Commands" on page 141 "DHCP Relay Commands" on page 146 "SNMP Commands" on page 148 "Flash/File Commands" on page 162 "RADIUS Client Commands" on page 165 "802. 1X Authentication Commands" on page 171 "MAC Address Authentication Commands" on page 173 "Filtering Commands" on page 177 "Spanning Tree Commands" on page 182 "WDS Bridge Commands" on page 193 "Ethernet Interface Commands" on page 195 "Wireless Interface Commands" on page 200 "Wireless Security Commands" on page 214 "Link Layer Discovery Commands" on page 224 ­ 110 ­ SECTION | Command Line Interface "VLAN Commands" on page 228 "WMM Commands" on page 231 ­ 111 ­ 11 USING THE COMMAND LINE INTERFACE When accessing the management interface for the over a direct connection to the console port, or via a Telnet connection, the access point can be managed by entering command keywords and parameters at the prompt. Using the access point's command-line interface (CLI) is very similar to entering commands on a UNIX system. CONSOLE CONNECTION To access the access point through the console port, perform these steps: At the console prompt, enter the user name and password. (The default user name is "admin" and the default password is "smcadmin") When the user name is entered, the CLI displays the "Enterprise AP#" prompt. After connecting to the system through the console port, the login screen displays EXAMPLE (none) login: accton Password: 1 03:47:41 login[2222]: root login Accton# on `ttyS0' NOTE: Command examples shown later in this chapter abbreviate the console prompt to "AP" for simplicity. ­ 112 ­ CHAPTER 11 | Using the Command Line Interface Telnet Connection TELNET CONNECTION Telnet operates over the IP transport protocol. In this environment, your management station and any network device you want to manage over the network must have a valid IP address. Valid IP addresses consist of four numbers, 0 to 255, separated by periods. For example, if the access point cannot acquire an IP address from a DHCP server, the default IP address used by the access point, 192. 168. 2. 1, consists of a network portion (192. 168. 2) and a host portion (1). To access the access point through a Telnet session, you must first set the IP address for the access point, and set the default gateway if you are managing the access point from a different IP subnet. For example: AP#configure AP(config)#interface ethernet AP(if-ethernet)#ip address 10. 1. 0. 1 255. 255. 255. 0 10. 1. 0. 254 AP(if-ethernet)# If your corporate network is connected to another network outside your office or to the Internet, you need to apply for a registered IP address. However, if you are attached to an isolated network, then you can use any IP address that matches the network segment to which you are attached. After you configure the access point with an IP address, you can open a Telnet session by performing these steps. 1. From the remote host, enter the Telnet command and the IP address of the device you want to access. 2. The CLI will display the "Enterprise AP#" prompt to show that you are using executive access mode (that is, Exec). 3. When finished, exit the session with the "quit" or "exit" command. After entering the Telnet command, the login screen displays: Username: admin Password: Enterprise AP# NOTE: You can open up to four sessions to the device through Telnet. ­ 113 ­ CHAPTER 11 | Using the Command Line Interface Entering Commands ENTERING COMMANDS This section describes how to enter CLI commands. KEYWORDS AND A CLI command is a series of keywords and arguments. Keywords identify ARGUMENTS a command, and arguments specify configuration parameters. For example, in the command "show interfaces ethernet, " show and interfaces are keywords, and ethernet is an argument that specifies the interface type. You can enter commands as follows: To enter a simple command, enter the command keyword. To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter: Enterprise AP(config)#username smith MINIMUM The CLI will accept a minimum number of characters that uniquely identify ABBREVIATION a command. For example, the command "configure" can be entered as con. If an entry is ambiguous, the system will prompt for further input. COMMAND If you terminate input with a Tab key, the CLI will print the remaining COMPLETION characters of a partial keyword up to the point of ambiguity. [. . . ] DHCP is based on the Bootstrap Protocol (BOOTP), adding PROTOCOL (DHCP) the capability of automatic allocation of reusable network addresses and additional configuration options. ENCRYPTION Data passing between the access point and clients can use encryption to protect from interception and evesdropping. ETHERNET A popular local area data communications network, which accepts transmission from computers and terminals. FILE TRANSFER A TCP/IP protocol used for file transfer. PROTOCOL (FTP) HYPERTEXT TRANSFER HTTP is a standard used to transmit and receive all data over the World PROTOCOL (HTTP) Wide Web. IEEE 802. 11A A wireless standard that supports high-speed communications in the 5 GHz band using Orthogonal Frequency Division Multiplexing (OFDM). The standard supports data rates of 6, 12, 24, and 54 Mbps. IEEE 802. 11B A wireless standard that supports wireless communications in the 2. 4 GHz band using Direct Sequence Spread Spectrum (DSSS).
