Re: [lwip-users] SNMP V3 Traps

[Indan Zupancic]

Hello Trampas,

We at MEP have implemented SNMP V1/V2c/V3 manager support (done by my colleague 
Harrold).

SNMP traps and manager functionality are very similar. We initially implemented 
manager support
by using snmp_traps.c's code. However, because V3 support was required and not 
supported for traps,
we switched to snmp_msg.c as a basis instead.

It shouldn't be that much work to adapt our manager code to also support V3 
traps.

I wanted to submit patches, but haven't gotten to it yet. Currently we 
duplicate code from snmp_msg.c
instead of sharing it. I can imagine that it is preferable to separate common 
code. However, this kind of
cleanups can also be done while adding V3 trap support.

If there is interest I'll hurry up our patch submission. We'd like to have V3 
trap support as well, but haven't
had the time to implement it yet.

Best regards,

Indan Zupancic

It appears that the SNMP V3 code does not implement SNMP V3 traps has anyone 
implemented V3 traps yet? 

Thanks
