Using the Topology Viewer

The Topology Viewer (Network Explorer –> Topology) enables you to visualize the network in a graph from the following viewpoints:

• Aggregate Network Topology: This shows the general Layer 2 paths of the network. For more information, see Aggregate Network Topology.
• L2 nHop Network Topology: This shows the Layer 2 switching paths of the network. For more information, see L2 nHop Network Topology.
• L3 nHop Network Topology: This shows the Layer 3 switching/routing paths of the network. For more information, see L3 nHop Network Topology.
• L2/L3 Most Likely Path Network: This indicates the spanning tree paths preferred by switched network traffic in the network. For more information, see L2/L3 Most Likely Path Network Topology.
• L3 Most Likely Path Network Topology: This indicates the routed paths preferred by most packet flows in the network. For more information, see L3 Most Likely Path Network Topology.
• VLAN Network Topology: This maps the paths of VLANs throughout the network. For more information, see VLAN Network Topology.
