attempted the same thing today (adding Aruba 2930 to AMP) and it failed the first time. Then, I added SNMP v3 community, user, and enabled SNMPv3 and it failed using those same creds on AMP. Then, I tried the same using SNMPv2c with a community and got the same result. I have tried every combination of using telnet/ssh, community, and user fields and always get an "SNMP get failed".
I was able to add CPPM to AMP just fine though, but not 2930 switches.
I want to start from scratch now.
What specific config on the 2930 needs to be configured? ,,,AND ...
What specific config on AMP needs to be configured on the DEVICE--> ADD page (ssh ? community ? user ?)
