#define SNMP_TRAP_PORT 162 |
#define SNMP_MAX_LEN 500 |
#define SNMP_VERSION_1 0 |
SNMPv1.
The original version, defined by RFC 1157.
Definition at line 70 of file snmp.h.
Referenced by SnmpAgentProcessRequest(), and SnmpAuthParse().
#define SNMP_VERSION_2C 1 |
SNMPv2c.
Community string-based SNMPv2, which was an attempt to combine the protocol operations of SNMPv2 with the security of SNMPv1, defined by RFCs 1901, 1905, and 1906.
Partly supplied by this code, work is in progress.

Parse an SNMP variable.
data | Pointer to start of the name/value pair. | |
dlen | Contains the number of valid bytes following the start of the variable. On exit, it is returned as the number of valid bytes following the end of this variable. | |
name | Pointer to a buffer that receives the name (OID). | |
nlen | On entry, this contains the maximum number of sub IDs accepted for the name. On exit, it is returned as the actual number sub IDs found in the name. | |
type | Pointer to the variable that receives the ASN type of the value. | |
value | Pointer to variable that receives a pointer to the ASN1 encoded value of variable. | |
vlen | Pointer to the variable that receives the length of the value. |
