Multicast agents
Multicast agents retrieve data from devices participating in multicast groups and routes.
The agents that retrieve multicast data need SNMP and Ping access to retrieve the data. Before enabling the multicast agents, ensure that you first configured SNMP to enable the agents to access devices and to specify threads, timeouts, and number of retries.
The following table describes the multicast agents.
| Agent name | Function |
|---|---|
| StandardIGMP | Discovers networks running the Internet Group Management Protocol (IGMP). Supports any device that complies with the RFC2933 IGMP MIB. Depending on the level of MIB support, the following information may be discovered: IGMP Interfaces; Per-Interface Group Memberships; Group Members Visible on IGMP Interfaces. |
| StandardIPMRoute | Discovers IP multicasting networks. Supports any device that complies with the RFC2932 IPMRoute MIB. Depending on the level of MIB support, the following information may be discovered: Multicast Routing data (upstream/downstream); Interfaces involved in Multicast Routing; Multicast Sources and Groups. |
| StandardPIM | Discovers networks running the Multicast protocol PIM. Supports any device that complies with the RFC2934 PIM MIB. Depending on the level of MIB support, the following information may be discovered: PIM Interfaces; PIM Adjacencies; Candidate RPs/BSR. |
