Need some help with setting up RSTP

Hi all,

i am in charge of setting up our new infrastructure (new switches, new ip-subnets/vlans) and i really need some help with Rapid Spanning-Tree.

 

The Hardware:

Switch	PoE	Use
5x Dell S3048-ON	No	Clustered to one big coreswitch.
1x Dell N1524P	Yes	Wireless Access Points
1x N1548P	Yes	Offices where we can let PoE over the (new) building wires
1x Dell N1524	No	Management Interfaces like idrac's etc.
a few Unifi 8 150W	Yes	Offices where we can not deliver power over ethernet due to old cables in our walls.

 

Every Switch is connected via Port-Channel. Always the last two Ports (No 10G Interfaces!) are used for Uplinks towards the Core.

The Coreswitch is already Root-Bridge with a set priority of 12288.

 

And now is the situation where i have more and more questions the more i try to get solutions for them:

 

1. How should i continue with my configuration?
2. Do i have to set EdgePorts manually? Is it the same as PortFast?
3. When and where should i configure RootGuard?
4. Are Port Priorities necessary when i use Port-Channels? If yes, on which interface? Gigabitethernet or Port-channel?
5. Do i have to set specific port costs?

 

Chances are high that more questions will be added, but i am grateful for any help!

Thanks in advance :)
