[AGENT++] changed default community, but trap not invoke

[변정수]

Hi, Jochen,

I asked 'how to change default community' of agent++ agent.
Thank you for the below answer.

But, after I applied below solution I got a trap problem.

I changed default community ( not 'public') At that time, GET and SET was OK with changed community string.
but, I failed to receive trap from manager.

( I could't see the TRAP packet on the ethernet packet capture program)


After , I changed community to 'public' I got a trap from agent.


Is ther any missing point below solution, especially for TRAP ?



Thanks in advance.

Best Regards
JS

you should change the VACM configuration, there are most likely some lines
like
        vacm->addNewGroup(SecurityModel_v2, "public",
                         "v1v2group", storageType_volatile);
        vacm->addNewGroup(SecurityModel_v1, "public",
                         "v1v2group", storageType_volatile); These
translate/add the v1 and v2c community public to the group v1v2group. Later
this group is given access to the different VACM views.
