Hello!
I configured my switch with admin-edge-port + bpdu-protection in all access ports.
...
spanning-tree 40 admin-edge-port
spanning-tree 40 bpdu-protection
spanning-tree 41 admin-edge-port
spanning-tree 41 bpdu-protection
spanning-tree 42 admin-edge-port
spanning-tree 42 bpdu-protection
...
When I do show running-config, appears, in the active ports this:
spanning-tree instance ist 8 path-cost 200000
spanning-tree instance ist 9 path-cost 200000
Why appears this in the running-config?
I think that must appears in the configuration of spanning-tree.
Now with switch configured, if I connect a PC in any port of switch, this port don't appears in running-config with path-cost. Then, I think line "spanning-tree instance ist 8 path-cost 200000" is a permanent cofiguration of port. Is correct?
I can't eliminate those lines with "no spanning-tree instance ist 8 path-cost 2000000". Only I eliminate the value of path-cost with "spanning-tree instance ist all path-cost auto" command. Then, disappears tha lines "spanning-tree instance ist 8 path-cost 200000".
Is this the correct configuration of RSTP in switch?
Regards!
