"preferably at AES128" doesn't seem to be up to date, I would prefer HMAC-SHA2 encryption.
Approaching this from a different direction, I would like to suggest another possibility.
Could you perhaps eliminate SNMP and replace it with NMIs. That would eliminate any SNMPv1 traffic (and SNMPv3 for that matter). It would also help my sanity as SNMPv3 is a bear to understand and configure.
Thankyou.
Due to processing by IBM, this request was reassigned to have the following updated attributes:
Brand - Servers and Systems Software
Product family - z Systems Software
Product - z/OS Communications Server
For recording keeping, the previous attributes were:
Brand - WebSphere
Product family - Enterprise Networking
Product - z/OS Communications Server
In the most recent update from IBM there is a request for more information ( we would like more information on your need or concern for encrypting this traffic ). Here is my response.
What I'm trying to do here, with this request, is to eliminate as much SNMPv1 as possible. I still need SNMPv1 configured in snmpd.conf for the subagents. If I could get rid of it entirely then I could prevent any access whatsoever via SNMPv1 (I'm currently using Target_Address to constrain access).
Another option to consider, would be to eliminate SNMP entirely and just use Network Management APIs to obtain the information currently provided by SNMP.
Thankyou.

The network traffic between the agent and subagent should all be local, meaning it never leaves the TCP/IP stack. Since this traffic will not be placed onto the network we would like more information on your need or concern for encrypting this traffic. The traffic would only be accessible via packet trace or data trace on the TCP/IP stack where the agent and subagents are running. Typically the packet trace and data trace are restricted to administrative roles and do not present an exposure to unencrypted data.
