The following are examples of data center access switch up-link port configurations for connecting to UCS C-Series servers. You must use virtual switch tagging (VST) and ensure that you have properly configured the correct corresponding setting between the network switches and the vSphere vSwitches.
Use auto negotiation for Gigabit connections on both the network switch and the ESXi host adapters.
It is essential that the network configuration be implemented correctly. Improper configuration of up-link ports can directly and negatively impact system performance, operation, and fault handling.
Use this configuration on a switch port that connects to the active or standby NIC on a UCS C-series host on the public network.
vlan 10 in this example is for the Packaged CCE Public VLAN. You can use any VLAN of your choosing.
