Router config ip route Specifically, the packets are sent to the configured PVC. Changes in dynamic routes are shared with other routers in the network. You can configure either of these routing protocols on your router. Example: Router config-router version 2 Router config-router Step 3 network ip-address Specifies a list of networks on which RIP is to be applied, using the address of the network of each Example: directly connected network.

Router config-router network This allows subprefix Example: routing information to pass across classful network Router config-router no auto-summary boundaries. To see this configuration, use the show running-config command from privileged EXEC mode. Router show running-config router rip version 2 network Router config network To see this configuration, use the show running-config command, beginning in privileged EXEC mode.

The wireless device is embedded and does not have an external console port for connections. Example: router config interface wlan-ap0 Always use port 0. Please use the service-module wlan-ap 0 session command to console into the embedded AP. Step 2 ip address subnet mask Specifies the interface IP address and subnet mask.

Step 5 ip address subnet mask Specifies the interface IP address and subnet mask. Example: router config-if ip address Example: router config-if exit router config Step 7 exit Exits the global configuration mode. Example: router service-module wlan-ap0 session Trying Control-Shift-6 x Router 1.

Type the disconnect command. Press Enter. Configure the wireless device with the tool that matches the software on the device. An Enter Network Password window appears. Step 3 Enter your username. Cisco is the default username. Step 4 Enter the wireless device password. Cisco is the default password. The Summary Status page appears. To serve different types of client devices with the same access point, configure multiple SSIDs.

Before a wireless client device can communicate on your network through the access point, the client device must authenticate to the access point by using open or shared-key authentication. Both authentication types rely on an authentication server on your network. The access point performs up to five authentications per second. You configure the local authenticator access point manually with client usernames and passwords because it does not synchronize its database with RADIUS servers.

Wireless devices and their wireless client devices use the same WEP key to encrypt and decrypt data. WEP keys encrypt both unicast and multicast messages. Unicast messages are addressed to one device on the network. Multicast messages are addressed to multiple devices on the network. Cipher suites are sets of encryption and integrity algorithms designed to protect radio communication on your wireless LAN.

Cipher suites that contain only WEP are the least secure. A VLAN can be thought of as a broadcast domain that exists within a defined set of switches. A VLAN consists of a number of end systems, either hosts or network equipment such as bridges and routers , that are connected by a single bridging domain. The bridging domain is supported on various pieces of network equipment such as LAN switches that operate bridging protocols between them with a separate group of protocols for each VLAN.

Static WEP key This option is more secure than no security. However, static Mandatory WEP. Client devices cannot WEP keys are vulnerable to attack. If you configure this associate using this SSID without a WEP setting, you should consider limiting association to the key that matches the wireless device key. If you do not configure open You are required to enter the IP address and shared secret authentication with EAP, the following key for an authentication server on your network server warning message appears: authentication port Because Client authenticated against a database.

Access is through the devices that associate using this SSID must services of an authentication server. If you do not configure open authentication port Configuring Wireless Quality of Service Configuring quality of service QoS can provide preferential treatment to certain traffic at the expense of other traffic. Without QoS, the device offers best-effort service to each packet, regardless of the packet contents or size.

It sends the packets without any assurance of reliability, delay bounds, or throughput. The standby access point is placed near the access point that it monitors and is configured exactly like the monitored access point. The standby access point associates with the monitored access point as a client and sends Internet Access Point Protocol IAPP queries to the monitored access point through the Ethernet and radio ports. If the monitored access point goes offline and the standby access point takes its place in the network, matching settings ensure that client devices can switch easily to the standby access point.

The following is a sample configuration: ip dhcp pool embedded-ap-pool network Step 2 Enter the service-module wlan-ap 0 session command to establish a session into the access point. Step 3 Confirm that the access point is running an autonomous boot image.

Step 4 Enter the show boot command on the access point to confirm that the mode setting is enabled. The following is a sample output for the command: show boot BOOT path-list: flash:apk9w7-mx. Establish a session into the access point and monitor the upgrade process.

My access point failed to upgrade from autonomous software to Cisco Unified software, and it appears to be stuck in the recovery mode. What is my next step? If the access point fails to upgrade from autonomous to Unified software, perform the following actions: — Check to ensure the autonomous access point does not have the static IP address configured on the BVI interface before you boot the recovery image. My access point is attempting to boot, but it keeps failing. My access point is stuck in the recovery image and does not upgrade to the Unified software.

The access point may attempt to boot and fail or may become stuck in the recovery mode and fail to upgrade to the Unified software. If either occurs, use the service-module wlan-ap0 reset bootloader command to return the access point to the bootloader for manual image recovery. To upgrade the bootloader, perform the following steps: Step 1 Verify the WLAN AP bootloader bundled with the host router image running on the first core using the show platform version command. To reload the access point with the autonomous software image, use the service-module wlan-ap 0 reload command.

This command returns the access point to the bootloader for manual image recovery. Caution Use this command with caution. It does not provide an orderly shutdown and consequently may impact file operations that are in progress. Use this command only to recover from a shutdown or a failed state. This document describes how to configure and manage SSIDs on the wireless device.

With this feature, you can provide preferential treatment to certain traffic at the expense of other traffic. SSIDs are case sensitive. Step 5 no shutdown Enables the radio port. Step 7 copy running-config startup-config Optional Saves your entries in the configuration file. Use the shutdown command to disable the radio port. The wireless device automatically assumes the fallback role when its Ethernet port is disabled or disconnected from the wired LAN.

The default fallback role for Cisco ISR wireless devices is as follows: Shutdown—the wireless device shuts down its radio and disassociates all client devices. Step 3 station-role Sets the wireless device role. Only one radio per access point may be configured as a workgroup bridge or repeater. A workgroup bridge can have a maximum of 25 clients, presuming that no other wireless clients are associated to the root bridge or access point.

Step 5 copy running-config startup-config Optional Saves your entries in the configuration file. Note When you enable the role of a device in the radio network as a bridge or workgroup bridge and enable the interface using the no shut command, the physical status and the software status of the interface will be up ready only if the device on the other end access point or bridge is up. Otherwise, only the physical status of the device will be up.

The software status will be up when the device on the other end is configured and ready. If the tracked radio goes down or is disabled, the access point shuts down the other radio. If the tracked radio comes up, the access point enables the other radio. To track radio 0, enter the following command: station-role root access-point fallback track d0 shutdown Fast Ethernet Tracking You can configure the access point for fallback when its Ethernet port is disabled or disconnected from the wired LAN.

Note Fast Ethernet tracking does not support the repeater mode. To configure the access point for Fast Ethernet tracking, enter the following command: station-role root access-point fallback track fa 0 MAC-Address Tracking You can configure the radio whose role is root access point to come up or go down by tracking a client access point, using its MAC address, on another radio.

If the client disassociates from the access point, the root access point radio goes down. If the client reassociates to the access point, the root access point radio comes back up. MAC-address tracking is most useful when the client is a non-root bridge access point connected to an upstream wired network. For example, to track a client whose MAC address is , enter the following command: station-role root access-point fallback track mac-address shutdown Configuring Radio Data Rates You use the data rate settings to choose the data rates that the wireless device uses for data transmission.

The wireless device always attempts to transmit at the highest data rate set to basic, also known as required on the browser-based interface. If there are obstacles or interference, the wireless device steps down to the highest rate that allows data transmission. At least one of the data rates of the wireless device must be set to basic.

You can use the data rate settings to set an access point to serve client devices operating at specific data rates. For example, to set the 2. To set the 2. You can configure the wireless device to set the data rates automatically to optimize either the range or the throughput.

The range setting allows the access point to extend the coverage area by compromising on the data rate. Therefore, if you have a client that cannot connect to the access point although other clients can, the client might not be within the coverage area of the access point. In such a case, using the range option will help extend the coverage area, and the client may be able to connect to the access point.

Typically, the trade-off is between throughput and range. When the signal degrades possibly due to distance from the access point , the rates renegotiate in order to maintain the link but at a lower data rate. A link that is configured for a higher throughput simply drops when the signal degrades enough that it no longer sustains a configured high data rate, or the link roams to another access point with sufficient coverage, if one is available.

The balance between the two throughput vs. When you enter throughput for the data rate setting, the wireless device sets all four data rates to basic. Note When a wireless network has a mixed environment of If you select [basic When you enter [basic This setting disables However, it prevents On the These rate settings allow both The modulation coding scheme MCS index range for both Use the no form of the speed command to remove one or more data rates from the configuration.

This example shows how to remove data rates basic MCS is used in the wireless device High-throughput clients support at least MCS 0—7. MCS is an important setting because it provides for potentially greater throughput.

High-throughput data rates are a function of MCS, bandwidth, and guard interval. Table shows potential data rated based on MCS, guard interval, and channel width. The following example shows a speed setting for an Step 3 power local Sets the transmit power for the 2. Use the no form of the power local command to return the power setting to maximum, the default setting.

When a client device associates to the wireless device, the wireless device sends the maximum power level setting to the client. Step 3 power client Sets the maximum power level allowed on client devices that associate to the wireless device. These options are available for Note The settings allowed in your regulatory domain might differ from the settings listed here. Use the no form of the power client command to disable the maximum power level for associated clients.

Note Aironet extensions must be enabled to limit the power level on associated client devices. Aironet extensions are enabled by default. At startup, the wireless device scans for and selects the least-congested channel. For the most consistent performance after a site survey, however, we recommend that you assign a static channel setting for each access point.

The channel settings on the wireless device correspond to the frequencies available in your regulatory domain. See the access point hardware installation guide for the frequencies allowed in your domain. Each 2. Because the bands for channels 1, 6, and 11 do not overlap, you can set up multiple access points in the same vicinity without causing interference.

The 5-GHz radio operates on 8 channels from to MHz, up to 27 channels from to MHz depending on regulatory domain. Each channel covers 20 MHz, and the bands for the channels overlap slightly. For best performance, use channels that are not adjacent use channels 44 and 46, for example for radios that are close to each other. Note The presence of too many access points in the same vicinity can create radio congestion that can reduce throughput.

A careful site survey can determine the best placement of access points for maximum radio coverage and throughput. One of the MHz channels is called the control channel. Legacy clients and MHz high-throughput clients use the control channel. Only beacons can be sent on this channel. The other MHz channel is called the extension channel.

The MHz stations may use this channel and the control channel simultaneously. A MHz channel is specified as a channel and extension, such as 1,1. In this example, the control channel is channel 1 and the extension channel is above it. Step 3 channel Sets the default channel for the wireless device radio. Step 5 copy running-config Optional Saves your entries in the configuration file. When you enable world mode, the wireless device adds channel carrier set information to its beacon.

Client devices with world mode enabled receive the carrier set information and adjust their settings automatically. For example, a client device used primarily in Japan could rely on world mode to adjust its channel and power settings automatically when it travels to Italy and joins a network there. Cisco client devices detect whether the wireless device is using You can also configure world mode to be always on.

In this configuration, the access point essentially roams between countries and changes its settings as required. World mode is disabled by default. Step 3 world-mode Enables world mode. Note Aironet extensions must be enabled for legacy world mode operation, but Aironet extensions are not required for Use the no form of the world-mode command to disable world mode. If these client devices do not associate to the wireless devices, you should use short preambles.

You cannot configure short or long radio preambles on the 5-GHz radio. Step 3 no preamble-short Disables short preambles and enables long preambles. Short preambles are enabled by default. Use the preamble-short command to enable short preambles if they are disabled. If the wireless device has two fixed non-removable antennas, you should use this setting for both receive and transmit.

Step 3 gain dB Specifies the resultant gain of the antenna attached to the device. If necessary, you can use a decimal in the value, such as 1. The antenna gain cannot be configured on these models. Step 4 antenna receive Sets the receive antenna to diversity, left, or right. For one antenna, attach the antenna on the right and set the antenna for right. Step 6 copy running-config startup-config Optional Saves your entries in the configuration file.

The MIC, implemented on the wireless device and all associated client devices, adds a few bytes to each packet to make the packets tamper-proof. Aironet extensions are not required for Step 3 no dot11 extension aironet Disables Aironet extensions.
