void snmp_authfail_trap ( void   )

Send authentication failure trap (used internally by agent)

Definition at line 263 of file lwip_snmp_traps.c.

void snmp_coldstart_trap ( void   )

Send coldstart trap.

Definition at line 253 of file lwip_snmp_traps.c.

u8_t snmp_get_auth_traps_enabled ( void   )

const char* snmp_get_community_trap ( void   )

Returns current SNMP community string used for sending traps.

Returns:
current SNMP community string used for sending traps

Definition at line 112 of file lwip_snmp_msg.c.

err_t snmp_send_trap ( const struct snmp_obj_id *  eoid,
s32_t  generic_trap,
s32_t  specific_trap,
struct snmp_varbind *  varbinds 
)

Sends a generic or enterprise specific trap message.

Parameters:
eoidpoints to enterprise object identifier
generic_trapis the trap code
specific_trapused for enterprise traps when generic_trap == 6
varbindslinked list of varbinds to be sent
Returns:
ERR_OK when success, ERR_MEM if we're out of memory
Note:
the use of the enterprise identifier field is per RFC1215. Use .iso.org.dod.internet.mgmt.mib-2.snmp for generic traps and .iso.org.dod.internet.private.enterprises.yourenterprise (sysObjectID) for specific traps.
