Chapter4 Installing the Cisco CSR 1000V in VMware ESXi Environments
VMware ESXi Support Information
Note The Cisco CSR 1000V does not use or support Cisco IOS-based high availability. High Availability is
supported on the VM host only.
Host-Level High Availability Cisco IOS XE Release
3.9S
To monitor physical servers, an agent on each server
maintains a heartbeat with the other servers in the resource
pool such that a loss of heartbeat automatically initiates the
restart of all affected virtual machines on other servers in the
resource pool. Host-Level High Availability is enabled by
creating a resource pool of servers or hosts, and enabling
high availability in vSphere.
Fault Tolerance Cisco IOS XE Release
3.10S
Using high availability, fault tolerance is enabled on the
ESXi host. When you enable fault tolerance on the VM
running the Cisco CSR 1000V, a secondary VM on another
host in the cluster is created. If the primary host goes down,
then the VM on the secondary host will take over as the
primary VM for the Cisco CSR 1000V.
