which type of spanning tree protocol should i implement ?

Hi Experts,
Iam a beginner in project and i need your help

I have 2 building (One core switch 4510 R-L) in every building
Every building has 4 floors (3 floor switch cisco 2960 in every floor)
And now I want to implement (Spanning Tree Protocol) who can help me as soon as possible
-      Core Switch has 4 VLANS as a follow :
VLAN 1 (for Management)
VLAN 2 (Users)
VLAN 3 and 4 (server)
Trunk Port encapsulation 802.1q (between Floor Switch and Core)

My Questions:
-      Which type of STP should I configure (RSTP, PVST , PVST+ ....etc )
-      Why , where , how configure Uplink Fast , Port Fast ( please expain to me simply )
-      Configuration Spanning tree In command Line ( in general )
Thanks

Frist of all , you need to check your IOS version support RTSP, RPVST+..etc. Since minimum software required. Please have a look:

Hi Dear ,
I have cisco Switches ( 4510R-L and 2960 TT-L ) and support RSTP

Use PVST+. You want PortFast on the ports connecting to hosts. For host ports you can use the command "switchport host", which turns on PortFast, and disabled DTP negotiation so the port will not become a trunk. Trunk port config would be:

interface fa2/15
 switchport trunk encapsulation dot1q
 switchport mode trunk

Here's a complete guide with examples:

Hi,

Portfast need on all PC, becouse STP blocking the teraffic for 30 sec when connected it to a port:

int gi0/1
 spanning-tree portfast

or on CatOS:
    Switch -A> (enable) set spantree portfast 2/1 enable

UplinkFast is a Cisco specific feature that improves the convergence time of the Spanning-Tree Protocol (STP) in the event of the failure of an uplink. The UplinkFast feature is supported on Cisco Catalyst 4500/4000, 5500/5000, and 6500/6000 series switches running CatOS. This feature is also supported on Catalyst 4500/4000 and 6500/6000 switches that run Cisco IOS® System Software and 2900 XL/3500 XL, 2950, 3550, 3560 and 3750 series switches. The UplinkFast feature is designed to run in a switched environment when the switch has at least one alternate/backup root port (port in blocking state), that is why Cisco recommends that UplinkFast be enabled only for switches with blocked ports, typically at the access-layer. Do not use on switches without the implied topology knowledge of a alternative/backup root link typically to distribution and core switches in Cisco multilayer design.

I think other experts gave you good examples!

on catos the spanning-tree porfast command is:

set spantree portfast

by default 4507 runs PVST (Per VLAN SPanning tree)



u only need rstp if u goona use GLBP protocol also for rappid converg.

From your drawing, I doesn't look like you've got an redundant links. If that's the case, STP is irrelevant.
