Build Information:

--
The current SNMP disector doesn't seem to handle AES256. Indeed, the only call
to the encryption library in packet-snmp.c is

err = gcry_cipher_open(&hd, GCRY_CIPHER_AES, GCRY_CIPHER_MODE_CFB, 0);

Many folks are using AES256 on Cisco routers that support it. I think all that
needs to be done is to add a "AES256" option to the user configuration and then
when that option is used call 

err = gcry_cipher_open(&hd, GCRY_CIPHER_AES256, GCRY_CIPHER_MODE_CFB, 0);

in place of the current call to the 128bit version of AES.
