The show commands described in this chapter provide validation of the two-rack leaf and spine configuration. The output is only a subset and does not show command output, interfaces, routes, or details for all switches. This is a subset of show commands related to the available configuration and only output for Leaf1A and might be truncated or not include the most current VMs. For more information, see the Enterprise SONiC Distribution by Dell Technologies SONiC User Guide and the SONiC Management Framework CLI Reference Guide on Dell Technologies Support website (login required).
To validate the Layer 2 VXLANs, perform a ping from one Leaf pair Host VM to the other leaf pair hosts VM, app-vm001, and app-vm003 by using the following command:
C:\> ping 172.18.11.214
Validation of the VNIs is through Leaf1A to Spine1 to Leaf2A. From Node1 VM(Leaf1A) in VLAN 1811 ping VM in VLAN 1811 in Node3(Leaf2A).
Now two nodes are used in the guest Network of VLAN 1814. vCenter moved the Nodes 2,3 into guest network.
A VM is created in each VxRail node and assigned and IP address in VLAN 1814. Ping from Node 2 vm to node 3 vm and the other way round.
Confirm the leaf switch interfaces are up by using the show interface status command. Repeat on each leaf switch. Use the show interface status | grep up command to verify that all required interfaces are up and links are established at their appropriate speeds. This command also displays other fields, such as speed, MTU, and alternate name. The output is from Leaf1A and may be truncated.
Confirm the VLAN status by using the show vlan command. Repeat for each leaf switch.
The show vlan command displays brief information about all the VLANs that are configured in the device. The output displays the VLAN ID, IP address (if configured for the VLAN), and a list of VLAN member ports, whether the port is tagged or in untagged mode.
Confirm the leaf status by using the show mclag brief command. Repeat for each leaf switch. The show mclag brief command displays brief information about the MC-LAG domain configured in the system and displays MC-LAG domain information and local/remote port status information for all the MC-LAG interfaces that are configured in the system.
