Can a WLC have multiple SNMP Trap Receivers with the same cummunity string?

My Monitoring team want me to send traps to three different trap collectors with the same SNMP Community string.

I have 2106's, 2504, 4400's, 5500's, 7510 all running either version 6 or 7.

Is this possible on a Wireless controller? If so, how?

Can a WLC have multiple SNMP Trap Receivers with the same cummun

Read this from my friends blog ..

"

Also you can configure SNMP trap receiver where WLC can send its snmp trap messages.  Community Name means SNMP trap receiver name & that does not have any significance like snmp community value."

It doesnt appear to have the same significants .. But I havent tested it

Yes, this is certainly possible.  From the WLC perspective just set up the community string you want to use:

http://www.cisco.com/en/US/docs/wireless/controller/7.0MR1/configuration/guide/cg_controller_setting.html#wpmkr1120672

On your trap receivers simply add the same community string and controller IP address.

Another consideration configure trap receiver on the WLC. Add the servers IP addresses collecting the traps and the traps will follow.

Can a WLC have multiple SNMP Trap Receivers with the same cummun

Here is my confusion. When I add a Trap receiver on the controller, it asks for "Community String" and "IP Address". It will not allow me to have 2 trap receivers with the same community string.

When I setup a template in PI 1.3, it has a field for "Template Name" and "IP address". Template Name must be unique.

When I apply the template to the controller, it takes the template name and puts it as the community string on the controller.

Is the WLC sending the trap with the the text in the community string field as the community string or is it not sending a community string?

Can a WLC have multiple SNMP Trap Receivers with the same cummun

I created 3 different templates in PI and pushed them out to the WLC's. On the controller the template name is in the field of community string.

I am waiting for my monitoring guy to tell me if he's getting traps on all 3 of his collectors. When I get then info I'll pass it on.

Thanks guys.

My monitoring team is reporting that they are getting the traps from the controllers. 

It would be very helpful if PI and the WLC would match on their terms and location of things. I think this is the biggest challenge that I have with PI now.

Thanks for your help!!
