[SNMP4J] RE: change community problem

[Frank Fock]

Hi Alex,

Are you aware that you are manipulating the
context "other"? Community names do not make
sense in a SNMPv3 context other than ""
(the default context).

You can map a v1/v2c community to a v3
security name and context, but that is
something different.

Best regards,
Frank
