Now as per our recent studies, we have figured out that the HP Switches does not support/interoperate with Cisco RPVSTP+ Mode. Now we have number of options to overcome this issue.<BR /> <BR />1. Downgrade from PVRSTP+ to MSTP or RSTP to comply with HP.<BR />2. Switch off the spanning tree on HP Switches as well as on VLANs on Cisco those will be extended to HP Switches.<BR /> <BR />The question is does anyone has experience where both Vendors are running together with the setup which I have currently running i.e. Cisco PVRSTP+ as Primary Root? If yes than if possible configuraiton can be shared?<BR /> <BR />Thanks in advance<BR /> <BR />Mansoor Hafeez Thu, 14 Apr 2011 14:23:44 GMT https://community.hpe.com/t5/switches-hubs-and-modems/stp-configuration-between-cisco-and-hp/m-p/4777642#M25786 Hameed Ahmad 2011-04-14T14:23:44Z https://community.hpe.com/t5/switches-hubs-and-modems/stp-configuration-between-cisco-and-hp/m-p/4777643#M25787 Look at the following links:<BR /><BR /><A href="http://cdn.procurve.com/training/Manuals/ProCurve-and-Cisco-STP-Interoperability.pdf" target="_blank">http://cdn.procurve.com/training/Manuals/ProCurve-and-Cisco-STP-Interoperability.pdf</A><BR /><BR /><A href="http://www.tecnocael.it/ftp/docs/ProCurve_Cisco.pdf" target="_blank">http://www.tecnocael.it/ftp/docs/ProCurve_Cisco.pdf</A><BR /><BR /><A href="http://www.techdata.com/techsolutions/networking/whitepapers/Feb10/HP%20Procurve%20Migrating%20from%20Cisco%20to%20ProCurve%20Networks.pdf" target="_blank">http://www.techdata.com/techsolutions/networking/whitepapers/Feb10/HP%20Procurve%20Migrating%20from%20Cisco%20to%20ProCurve%20Networks.pdf</A><BR /><BR />Hope this will provide you with some guidance.<BR /><BR />Olaf<BR /> Fri, 15 Apr 2011 03:28:41 GMT https://community.hpe.com/t5/switches-hubs-and-modems/stp-configuration-between-cisco-and-hp/m-p/4777643#M25787 Olaf Borowski 2011-04-15T03:28:41Z
