Chapter 1 Cisco CSR 1000V Series Cloud Services Router Overview
Cisco CSR 1000V Series Software License Overview
•When a Cisco CSR 1000V interface is directly connected to a physical router, and that physical router’s connecting interface goes down, the change is not reflected on the Cisco CSR 1000V. This is because the Cisco CSR 1000V is actually connected to the hypervisor’s vSwitch and the vSwitch uplink port is connected to the physical interface of the router. This behavior is expected.
•The Cisco CSR 1000V provides an MTU range from 1500 to 9216 bytes. However, ESXi 5.0 supports only a maximum value of 9000 bytes.
