CHAPTER 4: SYSTEM CONFIGURATION system” and “shared key.” Open-system authentication accepts any client attempting to connect to the access point without verifying its identity. The shared-key approach uses Wired Equivalent Privacy (WEP) to verify client identity by distributing a shared key to stations before attempting authentication. Associated: Shows if the station has been successfully associated with the access point.
Security Access point was set to “Open Authentication”, but a client sent an authentication request frame with a “Shared key.” Access point was set to “Shared Key Authentication,” but a client sent an authentication frame for “Open System.” WEP keys do not match: When the access point uses “Shared Key Authentication,” but the key used by client and access point are not the same, the frame will be decrypted incorrectly, using the wrong algorithm and sequence number.
CHAPTER 4: SYSTEM CONFIGURATION 4-76
COMMAND LINE INTERFACE USING THE COMMAND LINE INTERFACE ACCESSING THE CLI 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: 1.
CHAPTER 5: COMMAND LINE INTERFACE 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. Each address consists of a network portion and host portion. For example, if the access point cannot acquire an IP address from a DHCP server, the default IP address used by the access point, 168.254.
Using the Command Line Interface ENTERING COMMANDS This section describes how to enter CLI commands. Keywords and Arguments A CLI command is a series of keywords and arguments. Keywords identify 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.
CHAPTER 5: COMMAND LINE INTERFACE Showing Commands If you enter a “?” at the command prompt, the system will display the first level of keywords for the current configuration mode (Exec, Global Configuration, or Interface). You can also display a list of valid keywords for a specific command. For example, the command “show ?” displays a list of possible show commands: Enterprise AP#show ? APmanagement Show management AP information.
Using the Command Line Interface Negating the Effect of Commands For many configuration commands you can enter the prefix keyword “no” to cancel the effect of a command or reset the configuration to the default value. For example, the logging command will log system messages to a host server. To disable logging, specify the no logging command. This guide describes the negation effect for all applicable commands. Using Command History The CLI maintains a history of commands that have been entered.
CHAPTER 5: COMMAND LINE INTERFACE Configuration Commands Configuration commands are used to modify access point settings. These commands modify the running configuration and are saved in memory. The configuration commands are organized into four different modes: • Global Configuration (GC) - These commands modify the system level configuration, and include commands such as username and password.

CHAPTER 5: COMMAND LINE INTERFACE cipher-suite This command defines the cipher algorithm used to encrypt the global key for broadcast and multicast traffic when using Wi-Fi Protected Access (WPA) security. Syntax cipher-suite • aes-ccmp - Use AES-CCMP encryption for the unicast and multicast cipher. • tkip - Use TKIP encryption for the multicast cipher. TKIP or AES-CCMP can be used for the unicast cipher depending on the capability of the client.
Using the Command Line Interface • AES-CCMP (Advanced Encryption Standard Counter-Mode/CBCMAC Protocol): WPA2 is backward compatible with WPA, including the same 802.1X and PSK modes of operation and support for TKIP encryption. The main enhancement is its use of AES Counter-Mode encryption with Cipher Block Chaining Message Authentication Code (CBC-MAC) for message integrity. The AES Counter-Mode/CBCMAC Protocol (AES-CCMP) provides extremely robust data confidentiality using a 128-bit key.
CHAPTER 5: COMMAND LINE INTERFACE • Using the “software” option provides the best performance for a large number of clients on one radio interface. Throughput may be reduced when both 802.11a and 802.11g interfaces are supporting a high number of clients simultaneously. Example Enterprise AP(if-wireless a)#mic_mode hardware Enterprise AP(if-wireless g)# wpa-pre-shared-key This command defines a Wi-Fi Protected Access (WPA/WPA2) Pre-shared-key.
Using the Command Line Interface pmksa-lifetime This command sets the time for aging out cached WPA2 Pairwise Master Key Security Association (PMKSA) information for fast roaming. Syntax pmksa-lifetime minutes - The time for aging out PMKSA information.
CHAPTER 5: COMMAND LINE INTERFACE Default Setting Disabled Command Mode Interface Configuration (Wireless-VAP) Command Usage • Each time a client roams to another access point it has to be fully re-authenticated. This authentication process is time consuming and can disrupt applications running over the network. WPA2 includes a mechanism, known as pre-authentication, that allows clients to roam to a new access point and be quickly associated.
Using the Command Line Interface Link Integrity Commands The access point provides a link integrity feature that can be used to ensure that wireless clients are connected to resources on the wired network. The access point does this by periodically sending Ping messages to a host device in the wired Ethernet network. If the access point detects that the connection to the host has failed, it disables the radio interfaces, forcing clients to find and associate with another access point.
CHAPTER 5: COMMAND LINE INTERFACE host does not respond or is unreachable) exceeds the limit set by the link-integrity ping-fail-retry command, the link is determined as lost. Example Enterprise AP(config)#link-integrity ping-detect Enterprise AP(config)# link-integrity ping-host This command configures the link host name or IP address.

6 TROUBLESHOOTING If you have difficulty with the 3Com Wireless LAN access point, first check the following items in the configuration: Radio Settings page: Ensure that the SSID is the same on clients and the access point. Security page: Ensure that Encryption is the same on clients and the access point. Authentication page: Ensure that the Local MAC Authentication System Default is set to Allow. Ensure that 802.1x Authentication Settings are correct.
CHAPTER 6: TROUBLESHOOTING Symptom Solutions Verify the access point configuration. Review access point firmware revisions and update firmware if necessary. No operation. Make sure that there are no duplicate IP addresses on the network. Unplug the access point and ping the assigned address to make sure that no other device responds to that address. Confirm that the service area on the access point matches that on the clients. Verify that the clients are operating correctly.
Symptom Solutions To maintain wireless association, the service area and the security settings on the client and the access point must match exactly. Therefore, if you are associated with the access point that you are configuring and you change the access point service area or security, make sure to change the client service area to match. While you are configuring the access point, the Configuration Management System stops responding.
