Chapter 4 Installing the Cisco CSR 1000V in VMware ESXi Environments

VMware ESXi Support Information

Table 4-5	Supported VMware Features and Operations: Networking Features (continued)
		First Supported
		Cisco CSR 1000V
Supported Entities		Release	Description
NIC Teaming		Cisco IOS XE Release	From both vCenter Server and vSphere Client. Allows you
		3.9S	to set up an environment where each virtual switch connects
			to two uplink adapters that form a NIC team. The NIC teams
			can then either share the load of traffic between physical and
			virtual networks among some or all of its members, or
			provide passive failover in the event of a hardware failure or
			a network outage.
			Note NIC Teaming can cause a large number of ARP
			packets to flood the Cisco CSR 1000V and overload
			the CPU. To avoid this situation, reduce the number
			of ARP packets and implement NIC Teaming as
			Active-Standby rather than Active-Active.
vSwitch		Cisco IOS XE Release	From both vCenter Server and vSphere Client. A vSwitch is
		3.9S	a virtualized version of a Layer 2 physical switch. A vSwitch
			can route traffic internally between virtual machines and link
			to external networks. You can use vSwitches to combine the
			bandwidth of multiple network adapters and balance
			communications traffic among them. You can also configure
			a vSwitch to handle a physical NIC failover.
Table 4-6	Supported VMware Features and Operations: High Availability
		First Supported
		Cisco CSR 1000V
Supported Entities		Release	Description
VM-Level High Availability		Cisco IOS XE Release	To monitor operating system failures, VM-Level High
		3.9S	Availability monitors heartbeat information in the VMware
			High Availability cluster. Failures are detected when no
			heartbeat is received from a given virtual machine within a
			user-specified time interval. VM-Level High Availability is
			enabled by creating a resource pool of VMs using VMware
			vCenter Server.
