Removing Power During Firmware Update Can Corrupt Radio Firmware

When you update the firmware on the bridge, allow the unit to finish its start-up sequence before removing power. If you update the firmware and remove power before the bridge finishes the start-up sequence, the radio firmware might be corrupted, making the unit inoperable. If the radio firmware is corrupted, the radio indicator (the bottom of the three indicators on top of the unit) lights solid red and the following error message appears when the access point starts up:

Failed to start driver for port "awc0" (errno=0x006d0002)

If the bridge's radio firmware is corrupted, you must return the unit to Cisco for service.

You can safely remove power after a firmware update when the configuration management pages reappear in the command-line or web-browser interfaces, or when the three status indicators on top of the bridge complete the following pattern:

1. All three indicators light solid green, indicating that the access point is beginning to update the firmware.

2. The middle indicator lights solid green and the top and bottom indicators are not lit, indicating that the access point is updating the radio firmware.

When the middle indicator blinks or the top and bottom indicators blink, you can remove power.

Updating with the Browser from a Local Drive

When you update firmware with your browser, you browse to the drive that contains the new firmware and load the firmware from there. You can update three firmware components individually or you can update all the firmware components at once. It is simplest to update all the components at once, but in some situations you might want to update them individually.

Full Update of the Firmware Components

To update all the firmware components at the same time, click Through Browser on the Fully Update Firmware line on the Cisco Services Setup page. The Update All Firmware Through Browser page appears. Figure 10-2 shows the Update All Firmware Through Browser page.

Figure 10-2 Update All Firmware Through Browser Page

Follow these steps to update all three firmware components through the browser:


Step 1 If you know the exact path and filename of the new firmware image file, type it in the New File for All Firmware entry field.

If you aren't sure of the exact path to the new firmware image file, click Browse... next to the New File entry field. When the File Upload window appears, go to the directory that contains the firmware image file and select the file. Click Open.

Step 2 When the filename for the new firmware appears in the New File entry field, click Browser Update Now to load and install the new firmware. When the update is complete, the bridge automatically reboots.


Selective Update of the Firmware Components

To update firmware components individually, click Through Browser on the Selectively Update Firmware line on the Cisco Services Setup page. The Update Firmware Through Browser page appears. Figure 10-3 shows the Update Firmware Through Browser page.

Figure 10-3 Update Firmware Through Browser Page

Follow these steps to update one of the three firmware components through the browser:


Step 1 If you know the exact path and filename of the new firmware component, type it in the New File for [component] entry field.

If you aren't sure of the exact path to the new component, click Browse... next to the component's New File entry field. When the File Upload window appears, go to the directory that contains the component and select the file. Click Open.

Step 2 When the filename for the new component appears in the New File entry field, click Browser Update Now to load and install the new component. When the update is complete, the bridge automatically reboots.


Updating from a File Server

When you update the firmware from a file server, you load new firmware through FTP or TFTP from a file server. You can update the three firmware components—the management system firmware, the firmware web pages, and the radio firmware—individually or all at once. It is simplest to update all the components at once, but in some situations you might want to update them individually.

Full Update of the Firmware Components

To update all the firmware components at the same time, click From File Server on the Fully Update Firmware line on the Cisco Services Setup page. The Update All Firmware From File Server page appears. Figure 10-4 shows the Update All Firmware From File Server page.

Figure 10-4 Update All Firmware From File Server Page

Follow these steps to update all three firmware components from a file server:


Step 1 Click the File Server Setup link to enter the FTP settings. The FTP Setup page appears. Figure 10-5 shows the FTP Setup page.

Figure 10-5 FTP Setup Page

Step 2 Enter the FTP settings on the FTP Setup page.

a. Select FTP or TFTP from the File Transfer Protocol pull-down menu. FTP (File Transfer Protocol) is the standard protocol that supports transfers of data between local and remote computers. TFTP (Trivial File Transfer Protocol) is a relatively slow, low-security protocol that requires no user name or password.

b. In the Default File Server entry field, enter the IP address of the server where the bridge should look for FTP files.

c. In the FTP Directory entry field, enter the directory on the server where FTP files are located.

d. In the FTP User Name entry field, enter the user name assigned to the FTP server. If you selected TFTP, you can leave this field blank.

e. In the FTP Password entry field, enter the password associated with the user name. If you selected TFTP, you can leave this field blank.

f. Click OK. You return automatically to the Update All Firmware Through File Server page.

Step 3 On the Update All Firmware Through File Server page, type the filename of the new firmware image file in the New File for All Firmware entry field.

Step 4 Click Update From Server to load and install the new firmware. When the update is complete, the bridge automatically reboots.


Selective Update of the Firmware Components

To update firmware components individually, click From File Server on the Selectively Update Firmware line on the Cisco Services Setup page. The Update Firmware From File Server page appears. Figure 10-6 shows the Update Firmware From File Server page.

Figure 10-6 Update Firmware From File Server Page

To update one of the three firmware components from the file server, follow the steps listed in the "Full Update of the Firmware Components" section, but in Step 3, type the filenames of the firmware components you want to update in the components' entry fields. Click Update From Server to load and install the new firmware. When the update is complete, the bridge automatically reboots.

Distributing Firmware

Use the Distribute Firmware page to distribute the bridge's firmware to other Cisco Aironet bridges. Figure 10-7 shows the Distribute Firmware page. The distributing bridge and the bridges that receive the firmware must have a Default Gateway setting other than the default setting, which is 255.255.255.155 (the Default Gateway setting is on the Express Setup and Routing Setup pages).

The bridge sends its firmware to all the bridges on your network that:

Are running bridge firmware version 10.00 or newer

Can detect the IP multicast query issued by the distributing bridge (network devices such as routers can block multicast messages)

Have their web servers enabled for external browsing (see Web Server Setup)

Have the same HTTP port setting as the distributing bridge (the HTTP port setting is on the Web Server Setup page)

Have a Default Gateway setting other than the default setting, which is 255.255.255.255

If they have User Manager enabled, contain in their User Lists a user with the same user name, password, and capabilities as the user performing the distribution (the person logged in on the distributing bridge)

Figure 10-7 Distribute Firmware Page

Follow this link path in the browser interface to reach the Distribute Firmware page:

1. On the Summary Status page, click Setup.

2. On the Setup page, click Cisco Services Setup.

Follow these steps to distribute firmware to other bridges:


Step 1 Follow the link path to reach the Distribute Firmware page.

Step 2 To distribute all firmware components at once, verify that yes is selected for Distribute All Firmware. This is the default setup for the Distribute Firmware page.

To distribute the firmware components individually, select no for Distribute All Firmware, and click the checkboxes for the components you want to distribute.

Step 3 Click Start. The bridge's firmware is distributed to the bridges on your network. To cancel the distribution, click Abort.

When the distribution is complete, the bridges that received the firmware automatically reboot.


Distributing a Configuration

You use the Distribute Configuration page to distribute the bridge's configuration to other Cisco Aironet bridges. Figure 10-8 shows the Distribute Configuration page. The distributing bridge and the bridges that receive the configuration must have a Default Gateway setting other than the default setting, which is 255.255.255.155 (the Default Gateway setting is on the Express Setup and Routing Setup pages).

The bridge sends its entire system configuration except for its IP identity information and its User List. The configuration is sent and applied to all the bridges on your network that:

Are running bridge firmware version 10.05 or newer

Can detect the IP multicast query issued by the distributing bridge (network devices such as routers can block multicast messages)

Have their web servers enabled for external browsing (see the "Entering Web Server Settings and Setting Up Bridge Help" section)

Have the same HTTP port setting as the distributing bridge (the HTTP port setting is on the Web Server Setup page)

Have a Default Gateway setting other than the default setting, which is 255.255.255.255

If they have User Manager enabled, contain in their User Lists a user with the same user name, password, and capabilities as the user performing the distribution (the person logged in on the distributing bridge)

f. Click OK. You return automatically to the Setup page.

Step 3 Follow the link path in the web browser to reach the System Configuration Setup page.

Step 4 Click Read Config File From Server. The management system checks the server for several possible configuration filenames while attempting to load the configuration file. If the management system doesn't find the first filename, it continues to the next until it finds the file and loads it. It checks the server for the following names in the following order:

a. [system name].ini

b. [IP address].ini

c. [boot file from DHCP/BOOTP server].ini

d. [boot file from DHCP/BOOTP server].ini by TFTP


Resetting the Configuration

You can reset the bridge configuration to the default settings without resetting the bridge's IP identity, or you can reset the configuration to the default settings including the IP identity. If you reset the bridge's IP identity, however, you might lose your browser connection to the bridge.

Two buttons on the System Configuration Setup page reset the configuration to defaults:

Reset System Factory Defaults Except IP Identity—this button returns all bridge settings to their factory defaults except:

The bridge's IP address, subnet mask, default gateway, and boot protocol

The users in the User Manager list

The SNMP Administrator Community name

Reset All System Factory Defaults—this button returns all bridge settings to their factory defaults except:

The users in the User Manager list

The SNMP Administrator Community name


Note To completely reset all bridge settings to defaults, follow the steps in the "Resetting to the Default Configuration" section.


Follow these steps to reset the configuration to default settings:


Step 1 Follow the link path to reach the System Configuration Setup page. Figure 10-9 shows the System Configuration Setup page. The link path is listed under Figure 5-9.

Step 2 Click Reset System Factory Defaults Except IP Identity to reset the bridge configuration to the default settings without resetting the bridge's IP identity. Click Reset All System Factory Defaults to reset the configuration to the default settings including the IP identity.


Note If you reset the bridge's IP identity, you might lose your browser connection to the bridge.



Restarting the Bridge

Use the System Configuration Setup page to restart the bridge.

Click "Warm" Restart System Now to perform a warm restart of the bridge. A warm restart reboots the bridge.

Click "Cold" Restart System Now to perform a cold restart of the bridge. A cold restart is the equivalent of removing and then reapplying power for the bridge.
