Which specialized agents to run

Several agents need to run only when you need to discover certain device types or network technologies.

The specialized agents that you need to run depend on the devices and protocols in your network:

  • The Extreme agent can be used to extract layer 2 connectivity information, EDP neighbors, and VLAN details from Extreme switches.
  • The ExtremeESRP agent discovers Extreme Standby Routing Table information from Extreme routing switches.
  • The PnniForeSys agent discovers physical ATM connections between devices by using the PNNI (Private Network-to-Network Interface) connectivity information provided by the Marconi ASX series switches.
  • The ILMIForeSys agent discovers physical ATM connections between devices by using the ILMI (Interim Local Management Interface) connectivity information provided by the Marconi ASX series switches.
  • The CellPath90 agent discovers the ATM connection of a CellPath 90 WAN (Wide Area Network) multiplexer.
  • The Marconi3810 agent discovers the Ethernet connectivity of the ES-3810 switches running operating system version 4.x.x.
  • The MariposaAtm agent discovers the ATM connectivity of the SE420 and SE440 IADs.
    Note: The Ethernet switching and Frame Relay capabilities of these devices are not currently certified.
  • The ILMI agent discovers connectivity between ATM devices running ILMI that support the ATM Forum's ATM MIB. The CiscoPVC agent retrieves PVC data from Cisco devices.
  • The AtmForumPnni agent discovers connectivity between devices running ATM Forum PNNI that correctly support the ATM Forum's PNNI MIB.
  • For Cisco devices, run the CiscoMPLSSnmp agent if you have the MPLS MIBs enabled on a device, otherwise, use the CiscoMPLSTelnet agent.
  • For Juniper devices, run the JuniperMPLSTelnet agent if you wish to discover MPLS paths.
  • For Juniper ERX devices (formerly Unisphere), the UnisphereMPLSTelnet agent must be used to discover MPLS paths, as these devices are sufficiently different to the Juniper "M" series routers that a different agent is required.
  • The StandardMPLSTE agent discovers MPLS Traffic Engineered (TE) tunnels.
  • The StandardIGMP agent discovers networks running the Internet Group Management Protocol (IGMP).
  • The StandardIPMRoute agent discovers IP multicasting networks.
  • The StandardPIM agent discovers Protocol Independent Multicast (PIM) groups.
