quick question on cat os 6509 what does command
set spantree guard none do??
Please explain this to me
it disables spanning-tree guard on that port
Disables the spanning tree guard feature.
Hope to help
It is to do with whether or not you enable STP rootguard and STP loopguard on a port. If you configure "set spantree guard none" on the port then you are effectively disabling both rootguard and loopguard on that port.
