Checking Hardware and Software Compatibility

The PRE installed in the Cisco 10000 series router chassis must support the Cisco IOS software running
on the router. Use the show version command to check the PRE version installed.
To see if a feature is supported by a Cisco IOS release, to locate the software document for that feature,
or 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 at
http://www.cisco.com/cgi-bin/Support/CompNav/Index.pl
This tool does not verify whether line cards within a system are compatible, but does provide the
minimum Cisco IOS requirements for individual hardware line cards, modules, or options.
You must be a registered user on Cisco.com to access this tool.

Line Card VC Limitations
The Cisco 10000 series router supports four ATM service categories for virtual circuits (VCs):
•
•

The segmentation and reassembly (SAR) mechanism configures priority and additional traffic
