If I run RSTP, I don't need to run PortFast. However, to run BPDU guard, I need to turn on PortFast on every single port? Does PortFast override RSTP's native fast port convergence? I just don't want to turn on PortFast (more config for me to do) and I just want to enable BPDU guard globally. Is it possible to use BPDU guard without configuring PortFast on the interface? Thank you.
As of 7.2 of 6500 switch ,you can can set bpdu-guard on individual ports. Regardless of the the global bpdu-guard setting, if you enable bpdu-guard on individual ports and receive a bpdu, the port will errdisable. In the older 6.x code you had been running, this only worked with portfast enabled. As of 7.2, you can enable this on a per port basis without portfast.
Maybe i am missing something but why do you not have portfast on all you access ports.
The only way for a switch to know which are edge ports when running RSTP is to have this configured. You are removing one of the very nice features of RSTP since all port that are not edge ports will cause topology change notification to be sent to the root bridge everytime a use boots his PC.
RSTP does not really use the concept of portfast but cisco uses this keyword to mean EDGE port.
Cisco terminology is very confusing. As we all know, Portfast is Cisco proprietary protocol. I thought Portfast functionality is already built into RSTP and that's why I thought I don't need to enable portfast on the Edge Port. Is it true or am I wrong? If it is true that RSTP doesn't have portfast feature built into the protocol, I need to enable portfast on every switch and every platform?
