8 Switch validation
After switches are configured and devices are connected, the switch CLI is used to validate the network
configuration. This section provides a list of the most common commands and their output for the examples
used in this guide.
8.1 General validation commands
The commands and output shown in this section are for S5248F-Leaf1A in the dual switch with VLT topology.
The output of its peer, S5248F-Leaf1B, is similar. If the dual switch without VLT or single switch topology is
used, notes are added where differences exist.
Note: For additional commands and output related to the leaf-spine portion of the topology, such as BGP and
Uplink Failure Detection (UFD), see Dell EMC Networking Layer 3 Leaf-Spine Deployment and Best Practices
with OS10.
8.1.1 show interface status
The show interface status | grep up command is used to verify required interfaces are up, and
links are established at their appropriate speeds.
S5248F-Leaf1A# show interface status | grep up
Port Description Status Speed Duplex Mode Vlan Tagged-Vlans
Eth 1/1/9:1 JumpBox_DNS up 10G full A 1611 -
Eth 1/1/17 Node1_Port1 up 25G full T 1611 1612-1615,3939
Eth 1/1/18 Node2_Port1 up 25G full T 1611 1612-1615,3939
Eth 1/1/19 Node3_Port1 up 25G full T 1611 1612-1615,3939
Eth 1/1/20 Node4_Port1 up 25G full T 1611 1612-1615,3939
Eth 1/1/53 VLTi up 100G full -
Eth 1/1/54 VLTi up 100G full -
Note: For the dual switch without VLT topology, the output is identical to the above except for the description
of ports 1/1/53-54. For the single switch topology, the output includes all eight node ports, and ports 1/1/53-54
are not used.
8.1.2 show port-channel summary
The show port-channel summary command is used to view port channel numbers, interfaces used, and
status. In SmartFabric OS10, the VLTi is automatically configured as a static LAG using port channel 1000.
Ports 1/1/53 and 1/1/54 are port channel members, and (P) indicates each is up and active.
S5248F-Leaf1A# show port-channel summary
Flags: D - Down I - member up but inactive P - member up and active
U - Up (port-channel) F - Fallback Activated
