Cisco 800W WiFi configuration example

Cisco 800-series devices have embedded AP in them.

Here is an example of simple configuration of wireless network on these routers (851W, 871W еtс).

In this example Network SSID: WiFi-SSID
Encryption is WPA-TKIP
WPA key: wpakey01
Network: 10.23.45.0/24


dot11 ssid WiFi-SSID
 vlan 1
 authentication open 
 authentication key-management wpa
 guest-mode
 wpa-psk ascii 0 wpakey01

bridge irb

interface Dot11Radio0
 no ip address
 !
 encryption vlan 1 mode ciphers tkip 
 !
 ssid WiFi-SSID

interface Dot11Radio0.1
 encapsulation dot1Q 1 native
 no cdp enable
 bridge-group 1

interface BVI1
 ip address 10.23.45.1 255.255.255.0
 ip nat inside
 ip virtual-reassembly

bridge 1 protocol ieee
bridge 1 route ip

You will probably want to have DHCP for wireless clients as well:


ip dhcp pool WiFi
   network 10.23.45.0 255.255.255.0
   default-router 10.23.45.1 
   dns-server 8.8.8.8 8.8.4.4

Don’t forget to add new wireless network to your NAT rule, in order to reach out the Internet.

Dell PowerConnect switch firmware update

Step 1.
Download firmware archive from dell website: ftp://ftp.dell.com/Pages/Drivers/powerconnect-5548-all.html

Step 2 – Extract .ros and .rfb files and place them on TFTP server.
Copy .ros image to system partition and .rfb image to boot partition.

SW01# copy tftp://<TFTP-IP>/powerconnect_55xx-4108.ros system
SW01# copy tftp://<TFTP-IP>/powerconnect_55xx_boot-10014.rfb boot

Step 3 – Check the current boot image.

GEKZNS02# show bootvar

Unit Image Filename Version Date Status
—- —– ——— ——— ——————— ———–
1 1 image-1 4.0.1.11 16-Oct-2011 18:10:50 Active*
1 2 image-2 4.1.0.8 28-Aug-2012 11:17:36 Not active

“*” designates that the image was selected for the next boot

Step 4 – Change the active image to new firmware.

GEKZNS02# boot system image-2

Step 5 – Verify the change.

GEKZNS02# show bootvar

Unit Image Filename Version Date Status
—- —– ——— ——— ——————— ———–
1 1 image-1 4.0.1.11 16-Oct-2011 18:10:50 Active
1 2 image-2 4.1.0.8 28-Aug-2012 11:17:36 Not active*
