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.

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*

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

Step 6 – Reboot the switch

GEKZNS02# reload

This command will reset the whole system and disconnect your current session. Do
