I have been immersing myself in the Cisco STP documentation, but for the life of me I am not able to find anything relating to the toppology changes (aka ports logically going down) when certain commands are run.
Due being un-familar with STP when I set STP up, I missed some glaring best practices and I need to correct hem now. I am concern that when I do, the toppology is going to re-assess and the network will go down.
I need to enter the following on my core switches:
Sw1# spanning-tree vlan 2-400 priority 8192
Sw1# spanning-tree portfast bpduguard default
Sw1#(uplinks) spanning-tree loopguard default
Sw2# spanning-tree vlan 2-400 priority 16384
Sw2# spanning-tree portfast bpduguard default
Sw2#(uplinks) spanning-tree loopguard default
When entering the global commands will each switch recalculate the STP topology?
I assume that the interface command (spanning-tree loopguard root) will cause a logical shutdown like when entering spanning-tree portfast
Thanks for any feedback. Unfortunately I run a small shop and don't have the budget for test equipment.
