This section describes the SNMP collection agents. These agents are available in real-time workflow configurations.
The SNMP Collection agents package consists of the following:
- an SNMP Collection profile - This profile is used to import the set of Management Information Base (MIB) files that will be used to build the target UDRs. Usually, the set of MIB files is provided by the equipment vendor.
- an SNMP OID profile - This profile is used to configure UDR types and fields to poll, as an alternative to configuring this in the SNMP Request agent itself, making the configuration available for multiple agents.
- and two SNMP real-time agents:
- SNMP Request agent - This agent is used for polling management data by sending queries to the devices (network elements) on the network periodically. These queries determine the behavior of the devices, for example operational status, or the data in the MIB variables of the devices. A network element is often a router or a switch, but it can be anything that is SNMP-enabled.
- SNMP Trap agent - This agent is used to receive SNMP notifications (traps and informs), and convert them to UDRs to be processed further by the
Platform.
Overview
The following features are supported for usage of SNMP collection agents:
- SNMPv1, v2c, and v3 are supported.
- The SNMP Request agent maps all SNMP ASN.1 types to corresponding UDR attribute types including:
- INTEGER (including integer enumerations defined in MIB files)
- COUNTER
- COUNTER64
- GAUGE
- OCTET STRING (including BIT STRING)
- OPAQUE
- IPADDRESS
- OBJECT IDENTIFIER
- TIMETICKS
- IPv4 and IPv6 protocols are supported.
- The SNMP Trap agent supports all types of SNMP notifications: Traps (TRAPv1 and TRAPv2 PDU types) and informs.
- The SNMP Trap agent also supports enterprise specific traps and generic traps:
- Cold Start
- Warm Start
- Link Up/Down
- Authentication Failure
- EGP Neighborless
Network Elements
The SNMP Request agent uses a CSV file as the input source. This file holds the list of network elements to poll.
Extended MIB Support
If the target MIBs have any dependent MIBs, ensure that all the dependent MIBs are also loaded to avoid errors.
