does all switching products (Cisco and Linksys) support IEEE 802.1D-2004 (which incorporates and enhances RSTP and obsoletes STP). This is not always clear from the documentation and data sheets
Hello once again,
Using the Feature Navigator tool mentioned in my earlier post, you can verify whether a particular switch supports the STP, RSTP or MSTP. After you click on the "Search by Platform", you may select the platform and the IOS version you are interested in. In the provided list, you will be able to see which particular STP versions are supported on that device.
Unfortunately, the Feature Navigator does not explicitely describe feature of switching modules but as these are determined by the router's IOS, you can proceed by selecting the proper router platform and IOS version.
