Re: [lwip-users] How to add varbinds to SNMP traps?

[Marco Veeneman]

Hi Dirk,

Thanks for pointing this out. I will try to provide a patch to introduce varbinds to snmp traps again.

I have another question regarding SNMP. I see you added the option to execute a callback function after a succeeded set request.

How should this callback mechanism be used? For example to store the 'snmpEnableAuthenTraps' setting in non-volatile memory. Should there be a single callback function handling all set requests or should every object have it's own callback function?

Hello Marco,

this got lost during the rewrite of the SNMP stack. Since we do not use traps in our product, they did not get much attention. If you can provide a patch, I'd be happy to apply it.

Hi,

I'm currently using LwIP git master commit [0737cfb] and investigating to update to the latest master. I'm using the SNMP agent, including sending specific SNMP traps with varbinds.

I was checking the changes related to SNMP and in general it looks better than the 'old' implementation. But i have a question about the traps implementation in the current master:

In the 'old' implementation varbinds were added using the 'snmp_varbind_tail_add()' function call. How can i add varbinds to a specific trap in the 'new' implementation?
