The VM-VM path topology draws a detailed connection that exists between any two virtual machines in your environment.

The topology involves both Layer 3 and Layer 2 components. This topology can be viewed using the search query vm_name_1 to vm_name_2. If a path exists, the VM-VM path visualization proceeds to populate all the components that exist between vm_name_1 to vm_name_2 and also draws an animated path. If the routers are physical, then they are shown outside the boundary.

In the VM Path topology, if you hover your mouse on any of the routers, edges, or LDRs that are involved in the path, the complete routing or NAT information is shown.

The VM Underlay section that is on the right side of the VM Path topology shows the underlay information of the VMs involved and their connectivity to the top of the rack switches and the ports involved. In the VM underlay section, the components are labeled if you select Show labels under Path Details. In this section, the drop-down list at the top shows the endpoint VMs and the active VMs at the edges. For each edge VM, the neighboring drop-down list shows the ingress and the egress interface IP addresses. Based on the selection, the underlay path for that particular interface is shown. .

You can also reverse the path direction using the arrows on top of the topology map.

The topology map gives more visibility regarding the ports involved in the VM-VM path. In the Path Details section, the name of the actual port channel is shown.

Note:
  • There is no complete visibility for layer 2 on the physical front. If a packet is traversing from one switch to another, there maybe multiple switches involved. But the topology does not show the switches in the underlay network.
