[lwip-users] Spanning Tree Protocol on lwip?

[Bill Yang]

Hi,

 

I wonder if there is STP (Spanning Tree Algorithm Protocol) implement in lwip software. I am using freerots as my project’s embedded OS on Luminary’s microcontroller (LM3S6965 ARM Cortex-M3) to implement STP for a 1Gb Ethernet switch. If any one can provide information regarding this, it will be greatly appreciated.

 

Thanks,

Subject: [lwip-users] SNMP trap

 

Hi all,

I would like to send a SNMP trap. I know that lwIP offers to do that tanks to a call to :

err_t snmp_send_trap(s8_t generic_trap, struct snmp_obj_id *eoid, s32_t specific_trap);

But, I don't understand how to fill in the global structure trap_msg in order to include some variable bindings.

Would it be possible to have an example that shows how to fill in trap_msg with 1 or 2 variables bindings?

Thanks.
Best Regards.
