[ad name=”ad-articlebodysq”]In this post I’ll review how you can find a specific wireless device on your Motorola WS5100 Wireless LAN Switch. We’re going to use the poor mans “locationing” as opposed to the features and integration that Motorola is currently building into the WS5100 and RFS7000 switches to support products such as AeroScout.
We want to locate the following device wireless-laptop.acme.org so we need to start by identifying the IP address of the device. Thanks to Dynamic DNS we can be assured that our DNS servers will have that information.
C:\> nslookup wireless-laptop.acme.org. Server: 10.1.1.1 Address: 10.1.1.1#53 Name: wireless-laptop.acme.org Address: 10.1.195.55
In most circumstances we’d now need to identify the MAC address of the wireless device. We can skip that step since the WS5100 will have the IP address of the client for us to search against.

Note: if you have a lot of mobile units you can use grep;
WS5100# show wireless mobile-unit | grep "10.1.195.55" 9 00-1B-77-2A-99-05 30 11a 1 vlan 18 Y 10.1.195.55 7 Sec
Now that we have the MU (Mobile Unit) index (the first number on the line) we can get the full details;
WS5100# show wireless mobile-unit 9 MAC: 00-1B-77-2A-99-05, IP Address: 10.1.195.55, Type: 11a, State: data-ready Radio Config Index: 30, Bssid: 00-15-70-12-1D-78 Wlan: 1, Vlan: vlan 18, Voice: N, Powersave: N, Classification: normal Encryption Type: tkip (key index: 1) Authentication Type: eap Last Assoc: 7990 seconds ago, Last Activity: 23 seconds ago, Roam-Count: 18 DHCP state : DHCPNONE AP Scan Support: N Session Timeout: 100 days 00:00:00 Idle Timeout: 0 days 00:30:00
In the information above we can see that the MU is associated to radio 30, so let’s look at radio 30;
WS5100# show wireless radio 30 Radio: 30, Mac: <00-15-70-11-34-32>, Type: 11a, ap Index: 7, vlan 198 Current Channel: 36 [5180 MHz], Configured Channel: acs Current Power: 17 dBm, Max ESS: 16, Max BSS: 4, Num Mu: 11 BSS: 00-15-70-12-1D-78, State: normal Current Data-Rates/Speed: basic6 9 basic12 18 basic24 36 48 54 Last Adoption: 0 days 20:55:16 ago Configuration: Adoption-pref-id: 0 Max-mobile-unit: 256, Detector: N, On-channel-scan: N WLAN-BSS mapping: [BSS 1]: 1 RTS-thres: 2346 bytes, Beacon-intvl: 100 K-uSec Dtim-count: [BSS 1]: 10 beacons Dtim-count: [BSS 2]: 10 beacons Dtim-count: [BSS 3]: 10 beacons Dtim-count: [BSS 4]: 10 beacons CCA level: 1, CCA Mode: 1, mobile-unit power: 0 dBm Short-Preamble: disabled, Antenna-Mode: diversity (both antennas) Placement: indoor, Channel-Mode: acs, Power: 20 dBm Data-Rates/Speed: basic6 9 basic12 18 basic24 36 48 54 WMM [best-effort]: aifsn: 3 txop-limit: 0 cwmin: 4 cwmax: 6 admission-control: disabled, max-mobile-unit: 32 WMM [background]: aifsn: 7 txop-limit: 0 cwmin: 4 cwmax: 10 admission-control: disabled, max-mobile-unit: 32 WMM

It doesn’t look like the Motorola switch shows us the radio description above so we’ll need to use another command to get the description;
WS5100# show wireless radio config 30
Radio: 30, Description: Main Building Lobby, MAC: 00-15-70-11-34-32

So it looks like the device we’re looking for, wireless-laptop.acme.org (10.1.193.55), is connected to radio 30 (802.11a) which has a description of “Main Building Lobby”. While this will give you an idea of the basic location it doesn’t provide you a specific location. While there are new APIs in the WS5100 and RFS7000 that can provide locationing by means of triangulation between multiple Access Ports, they require external applications and management software.
Obviously you’ll need to make sure that you’ve put descriptive locations on each radio (AP300) through the Motorola console when configuring/installing the APs.
Cheers!
I am looking for a script fot the WS5100 wireless controllers version 3.2 that will allow me to make configuration changes to the controllers. I am having problems with the sign in since there needs to be a pause after the cli is entered.
I you provide some information on how write a script that will change the config?
Thanks,
Dotty
Hi Dotty,
I’m not exactly sure what you’re trying to say… if your looking for examples of how to write an Expect script you can have a look at this post describing a script I wrote to dump debug information from a Nortel ERS 8600 switch.
You realize that the Motorola WS5100 has a web based management GUI right? You only need to connect to the switch IP address over SSL (HTTPS). If the IP address of your Motorola WS5100 was 192.168.1.10 you would enter the following in your web browser; https://192.168.1.10. You need to acknowledge the unsigned SSL certificate error that will popup in both Internet Explorer and Firefox (or any other browser for that matter).
Good Luck!
Thanks for your reply. Let me explain what exactly I need to do. I need to add an additional wlan to all of our WS5100 wireless controllers. I can easily do this through the gui as you suggested, but webbing to each controller consumes a lot of time. I can also telnet to each controller and paste in the config starting with the enable command, but that also takes time. I would like to create a batch file or visual basic script that would telnet to each wireless controller sign in and then make the necessary config changes. I cannot get the sign in to work because of the cli prompt. I think I need some sort of a pause after I enter the cli command.. Please let me know if you can help or point me in the right direction.
Hi Dotty,
Thanks for the clarification…
I would guess that unless you are managing a lot of WS5100s that you’re going to spend a lot more time trying to develop a solution over just manually copying the configuration files. In your case (depending on the version of software on the WS5100) you could just place the configuration commands in a single text file on a TFTP server and then copy those commands to each server with the following command;
copy tftp://10.1.1.1/commands.txt running-config
write mem
In any event I don’t believe that batch files alone will provide you the solution. I really don’t code in Visual Basic so I can’t really help. I have written some extensive Expect scripts for the WS5000/WS5100/RFS7000 switches. Here’ a quick snipet of the Expect code that I used to login;
Good Luck!
