| void snmp_init | ( | void | ) |
Starts SNMP Agent.
Agent setup, start listening to port 161.
Allocates UDP pcb and binds it to IP_ANY_TYPE port 161.

| void snmp_set_community | ( | const char *const | community ) |
Sets SNMP community string.
The string itself (its storage) must be valid throughout the whole life of program (or until it is changed to sth else).
- Parameters:
-
community is a pointer to new community string
Definition at line 89 of file lwip_snmp_msg.c.
| void snmp_set_community_write | ( | const char *const | community ) |
Sets SNMP community string for write-access.
The string itself (its storage) must be valid throughout the whole life of program (or until it is changed to sth else).
- Parameters:
-
community is a pointer to new write-access community string

| void snmp_set_device_enterprise_oid | ( | const struct snmp_obj_id * | device_enterprise_oid ) |
'device enterprise oid' is used for 'device OID' field in trap PDU's (for identification of generating device) as well as for value returned by MIB-2 'sysObjectID' field (if internal MIB2 implementation is used).
The 'device enterprise oid' shall point to an OID located under 'private-enterprises' branch (1.3.6.1.4.1.XXX). If a vendor wants to provide a custom object there, he has to get its own enterprise oid from IANA (http://www.iana.org). It is not allowed to use LWIP enterprise ID! In order to identify a specific device it is recommended to create a dedicated OID for each device type under its own enterprise oid. e.g. device a > 1.3.6.1.4.1.XXX(ent-oid).1(devices).1(device a) device b > 1.3.6.1.4.1.XXX(ent-oid).1(devices).2(device b) for more details see description of 'sysObjectID' field in RFC1213-MIB
Definition at line 242 of file lwip_snmp_core.c.
| void snmp_set_mibs | ( | const struct snmp_mib ** | mibs, |
| u8_t | num_mibs | ||
| ) |
Sets the MIBs to use.
Example: call snmp_set_mibs() as follows: static const struct snmp_mib *my_snmp_mibs[] = { &mib2, &private_mib }; snmp_set_mibs(my_snmp_mibs, LWIP_ARRAYSIZE(my_snmp_mibs));
Definition at line 220 of file lwip_snmp_core.c.
| void snmp_set_write_callback | ( | snmp_write_callback_fct | write_callback, |
| void * | callback_arg | ||
| ) |
Callback fired on every successful write access.
