Hardware and Software Requirements

Software Requirements

Table 2-1lists the recommended minimum Cisco IOS software release required to use the VSA in supported router or switch platforms. Use the show version command to display the system software version that is currently loaded and running.

Table 2-1 VSA Software Requirements

Platform

Cisco 7204VXR Cisco 7206VXR

Recommended Minimum Cisco IOS Release

12.4(4)XD3 fc2

To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. Registered Cisco Direct users can access the Software Advisor at: http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl. This tool does not verify whether modules within a system are compatible, but it does provide the minimum Cisco IOS software requirements for individual hardware modules or components.

Note Access to this tool is limited to users with Cisco.com login accounts.

Hardware Requirements

The hardware required to ensure proper operation of the VSA is as follows:

•The VSA is compatible with the Cisco NPE-G2 processor on the Cisco 7204VXR or Cisco 7206VXR routers.

The Cisco NPE-G2 is the latest routing engine for the Cisco 7204VXR and 7206VXR, which provides the highest performance and scalability within the family of network processing engines (NPEs).

•ROMmon requirement—12.4(4r)XD5

•I/O FPGA requirement—0x25 (decimal 0.37)

•VSA FPGA requirement—0x13 (decimal 0.19)

Restrictions

The VSA has the following restrictions:

•VSA does not interoperate with other ISA or VAM/VAM2/VAM2+ crypto cards in the same router. The VAM/VAM2/VAM2+ crypto cards are disabled when the VSA is active in the Cisco 7200VXR series routers with the NPE-G2 processor.

•Only a single VSA card is supported on the Cisco 7200VXR series routers with the NPE-G2 processor.

Note Only Cisco 7200VXR series routers with the NPE-G2 processor are supported.
