SolarWinds Network Topology Mapper (NTM) shows nodes on your network, indicates and updates status both for the nodes and the network connections between them in interrelated, scalable maps with customizable icons.
NTM’s topological overview complements your network monitoring system (SolarWinds Network Performance Monitor (NPM), by showing how an issue with a particular node impacts larger aspects your network. While NPM lists alerts in order or urgency, NTM distributes alerts on a map that clearly indicates, for example, that a particular switch sits in the path of all other alerting nodes.
NTM uses the following protocolso to discover network nodes and the connectivity between them:
SNMP interrogates several device MIBs, including:
NTM cannot poll the ipRouteTable MIB for Cisco devices running on IOS release 12.4(13b) and later releases.
After node detail and connectivity data is retrieved from nodes, NTM uses bridge table information if you chose that option in Discovery Settings.
