71 Dell EMC PowerEdge MX SmartFabric Configuration and Troubleshooting Guide
NOTE: If the connections to the MX switches do not come up, see Section 12.5.1 and Section 12.5.4 for
troubleshooting steps.
Trunk ports on switches allow tagged traffic to traverse the links. All flooded traffic for the a VLAN will be sent
across trunk ports to all the switches even if those switches do not have associated VLAN. This takes up the
network bandwidth with unnecessary traffic. VLAN or VTP Pruning is the feature that can be used to eliminate
this unnecessary traffic by pruning the VLANs.
Pruning restricts the flooded traffic to only those trunk ports with associated VLANs to optimize the usage of
network bandwidth. If the existing environment is configured for Cisco VTP or VLAN pruning, ensure that the
Cisco upstream switches are configured appropriately. See See
Cisco Nexus 3000 Series NX-OS
configuration guides for additonal information.
10.2 Configuration validation
This section covers the validation of the Cisco Nexus 3232C leaf switches. For information about the Dell
EMC Networking MX switch validation commands, see Section 8.4
.
10.2.1 show vpc
The show vpc command validates the vPC configuration status. The peer adjacency should be OK, with the
peer should show as
alive. The end of the command shows which VLANs are active across the vPC.
