Software and Hardware Requirements and Compatibility

Note The Cisco IOS Release 12.1 Mainline does not support the ISA/ISM.

Software Compatibility

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.

Interoperability Between ISA/ISM and VAM

Note The Cisco 7100 series routers support ISM and the SA-VAM; the Cisco 7200 series routers support ISA and SA-VAM; and the Cisco 7200 series routers support two ISAs in the same chassis.

Table 2-2describes the interoperability between ISA and VAM. You can use ISA with VAM, provided you observe the following conditions:

•The system supports two ISAs in the same Cisco7200 series router chassis. If one ISA is enabled at system bootup, and a second ISA is added later, the second ISA becomes active immediately, and depending on the configuration, the system attempts to load-balance between the two ISAs.

•If ISA and VAM are in the chassis at system bootup, the Cisco 7200 series router supports the newer version, in this case, VAM, provided the Cisco IOS Release supports VAM; and the ISA remains inactive.
