I recently started working with
net-snmp-5.8. I had a query over a change that was made to
agentx_parse() in agent/mibgroup/agentx/protocol.c. I noticed
that the buffer of  SNMP_MAX_MSG_SIZE (1472) in net-snmp-5.7.3
has been replaced with the size 65536 in net-snmp-5.8.

u_char buffer[65536];

I didnÂ’t find any clarification in the
ChangeLogs for this large increase of size. Can this size be
reduced? It would be of great help if anyone can clear me out
on this since my application has memory constraints.
Hi Anjali,
I will have a look and see whether it is possible to modify the
AgentX code without reducing performance and without dropping
support for large AgentX packets. BTW, the following commit
increased the buffer size:
c09140c934eb ("CHANGES: snmpd: Increase maximum AgentX packet
size to 64kB.")
Bart.
