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.

Server Requirements

The server and processor requirements are different depending on the Cisco CSR 1000V release.

Table 1-3	Server Requirements
Cisco CSR 1000V Release		Intel	AMD
Cisco IOS XE Release		Intel Nehalem and	Not supported
3.9S		later-generation
		processors are
		supported.
Cisco IOS XE Releases		Intel processors prior	Supported
3.10S, 3.11S, 3.12S		to the Nehalem
		generation are
		supported.

For more information, see the Cisco CSR 1000V Series Cloud Services Router Release Notes.

Note In Cisco IOS XE Release 3.9S and earlier, the Cisco CSR 1000V uses instructions not supported on Intel pre-Nehalem generation processors. The existence of the required Nehalem or later processor instruction set is determined at boot time. If the required instructions are not present, the following message is displayed:

%IOSXEBOOT-4-BOOT_HALT: (rp/0): Halted boot due to missing CPU feature

Cisco CSR 1000V Series Software License Overview

The Cisco CSR 1000V Series software supports the standard Cisco software licensing process in Cisco IOS XE. The software activation process is similar to other Cisco router products, but there are some differences and additional requirements.

The Cisco CSR 1000V supports the following license types depending on the software release:

•Perpetual and subscription term licenses for 1, 3, and 5 years based on the following attributes:

–Cisco IOS XE technology packages (Standard, Advanced and Premium)

–Maximum supported throughput level (10, 25, 50, 100, 250, or 500 Mbps, and 1, 2.5 or 5 Gbps )
