Hello,

How can i enable the networks ports to works as one, like in MCS we enabled the fault-tolerance?

Yes but it's done differently with virtualized installations. On the MCS hardware the platform was installed directly on "bare metal". Because of this the OS had two NICs and needed to be configured to failover from one to the other through a CLI command. In a virtualized environment the virtual machine has only one NIC. VMware ESXi provides a virtual software switch that bridges this virtual NIC (vNIC) to one or more physical NICs. Because of this you need to implement the resiliency/teaming functionality between the ESXi hypervisor and the physical switch, not between the VM and the hypervisor. This is a VMware design/configuration, not a Cisco UC configuration task now.

You would need to add multiple active NICs (not standby!) to the vSwitch in ESXi. By default the vSwitch will load balance by pinning (don't confuse this with UCS Manager pinning) each VM to a different active NIC. If that NIC goes down the VM will be pinned to a different NIC. If you want traffic to be spread across the multiple NICs you would need to configure an EtherChannel.

Hello Jonathan,

I wanna do the NIC teaming feature allows a  server to be connected to the Ethernet  via two NICs and, therefore, two  cables. NIC teaming prevents network  downtime by transferring the  workload from the failed port to the  working port. NIC teaming cannot be  used for load balancing or  increasing the interface speed.

Its possible?
