Wism2 SNMP Authentication Failure

Question

I cannot seem to communicate with my new Wism2 via SNMP.
The configuration is the same as on my Wism 1, same version of code, same SNMP settings and strings and subnets.
Slot  Controller  Service IP       Management IP    SW Version    Controller Type    Status
----+-----------+----------------+----------------+------------+------------------+---------------
1     1           192.168.10.2     10.XX.XX.10      7.0.116.0    WS-SVC-WISM-1-K9   Oper-Up
1     2           192.168.10.3     10.XX.XX.15      7.0.116.0    WS-SVC-WISM-1-K9   Oper-Up
3     1           192.168.10.4     10.XX.XX.20      7.0.116.0    WS-SVC-WISM-2-K9   Oper-Up
SNMPWalk of the Wism1 controllers is fine.  SNMPWalk of the Wism2 just gets me a timeout.
The snmplog does occasionally register an Authentication failure
Trying V1 and V2c with the same results.
Any advice?

Answer 1

on thew new WiSM2 did you issue the command config network-mgmt-via-dyamic interface enable?
by default the WLC has issues with responding to requests from the wire, for a subnet that it is configured to use.  The above is the workaround to this situation.
Per the best practices guide, "It is important to avoid configuring a dynamic  interface in the same sub network as a server that has to be reachable  by the controller CPU, for example a RADIUS server, as it might cause  asymmetric routing issues."
