Update SNMP to v3 on WLCs. Update also required on WCS?

Question

Hi all,
I need to update the SNMP version on our WLCs to v3, using MD5 and aes128.  This looks easy enough to do:
Management > SNMP > SNMP v3 users > new
From here i can add a new user (ie SNMPV3) and set MD5 and aes128 passwords. I will update our monitoring software to match the SNMP version and credentils, and our monitoring of the WLCs will then run under SNMP v3.
However, we also use a WCS to manage the WLCs (we use templates for wireless key changes etc)
I suspect i will need to update the SNMP details on here too, PER WLC ?
Configure > Controllers > (IP of specific WLC) > Properties > SNMP Properties
Within here i believe i need to add the MATCHING SNMPv3 credentials that i added to the WLC in queston, presumably so the WCS can still talk to the WLC..?  Is this correct, or is there more than this that is required?
I also assume that any SNMP update on the WLCs and WCS will NOT impact the APs, because they chat to the WLCs via LWAPP and *not* SNMP...?
Thoughts appreciated,
Thanks in advance!

Answer 1

You are quite correct.  You will need to update the v3 user on the WCS per WLC.  And yes, it will not affect the AP.
