| Macros | |
| TCPIP_SNMP_BIB_FILE_NAME | The Microchip mib2bib.jar compiler is used to convert the Microchip MIB script to binary format and it is compatible with the Microchip SNMP agent. which is written in ASCII format. Name of the bib file for SNMP is snmp.bib. |
| TCPIP_SNMP_COMMUNITY_MAX_LEN | This is the maximum length for community string. Application must ensure that this length is observed. SNMP module adds one byte extra after TCPIP_SNMP_COMMUNITY_MAX_LEN for adding '0' NULL character. |
| TCPIP_SNMP_MAX_COMMUNITY_SUPPORT | Specifying more strings than TCPIP_SNMP_MAX_COMMUNITY_SUPPORT will result in the later strings being ignored (but still wasting program memory). Specifying fewer strings is legal, as long as at least one is present. |
| TCPIP_SNMP_MAX_MSG_SIZE | The maximum length in octets of an SNMP message which this SNMP agent able to process. As per RFC 3411 snmpEngineMaxMessageSize and RFC 1157 ( section 4- protocol specification ) and implementation supports more than 480 whenever feasible. It should be divisible by 16 |
| TCPIP_SNMP_MAX_NON_REC_ID_OID | Update the Non record id OID value which is part of CustomSnmpDemoApp.c file. This is the maximum size for gSnmpNonMibRecInfo which is the list of static variable Parent OIDs which are not part of mib.h file. This structure is used to restrict access to static variables of SNMPv3 OIDs from SNMPv2c and SNMPv1 version. With SNMPv3 all the OIDs accessible but when we are using SNMPv2c version , static variables of the SNMPv3 cannot be accessible with SNMP version v2c. SNMP agent supports both SMIv1 and SMIv2 standard and snmp.mib has been updated with respect to SMIV2 standard and it... more |
| TCPIP_SNMP_NOTIFY_COMMUNITY_LEN | Maximum length for SNMP Trap community name |
| TCPIP_SNMP_OID_MAX_LEN | Maximum length for the OID String. Change this to match your OID string length. |
| TCPIP_SNMP_TASK_PROCESS_RATE | SNMP task processing rate, in milli-seconds. The SNMP module will process a timer event with this rate for processing its own state machine, etc. The default value is 200 milliseconds. The lower the rate (higher the frequency) the higher the module priority and higher module performance can be obtained The value cannot be lower than the TCPIP_STACK_TICK_RATE. |

| TCPIP_SNMPV3_USM_MAX_USER | Maximum number of SNMPv3 users. User Security Model should have at least 1 user. Default is 3. |
