Seems no one likes to just give anyone the answer here. So here it is. lol
Took me days to figure all this out but once you start learning how to do it the rest a breeze. I work for an ISP we use Motorola Canopy. We have hundreds and hundreds of Canopys in use as AP's SM's etc. The Dude is an awesome program once you get it down to a science.
Here is some helpful hints etc for getting dude to display canopy info.
First you can start with something simple like your canopy address and just set up a simple ping service on the Item you just created in dude. Next you need to make sure you know what your community string your Canopy is using under its SNMP settings. Once you have that just make an SNMP profile under settings. Lets say your community string on your canopy is named "public" so we go make a new one lets name it V2 Public SNMP the version will be 2c Port number 161. Now we have that made select the SNMP profile you just made by right clicking your canopy Icon we made earlier and in the top right choose the V2 Public SNMP. Now we just have to add some info to the label for Color Code, SM Count etc. Once you are ready to start displaying some info on your canopy Icon right click on the Icon and choose appearance In this window look for "Label" next Click in the box and if there is anything in there just delete it. Add this for starters.
Sm Count [oid("220.127.116.11.18.104.22.168.22.214.171.124.0")]
Just like it should show you the up time, Color Code and SM count. There's lots more to do but thats a start.
The above codes can be found with some searches to do with canopy. Now if you wanna monitor speed from and the Canopy you can make a link. Right Click on the Link after its made select SNMP if you did everything right above you will have two choices under Interface. One is Motorola 10/100 FEC, and the other is Canopy MultiPoint. The 10/100 Is of course the Ethernet side of the canopy. The Multipoint is the Wireless side. Now once you have that set up you can right click the link go to Appearance and under label enter this.
You should be golden now. Let me know if you have any questions. I have to figure this all out by myself I hope I can save you all some time.
Canopy's use Version 2 of SNMP.
