Model: T2600G-52TS(TL-SG3452)  
Hardware Version: V2
Firmware Version: 2.0.0 Build 20170323

I am attempting to confirm that I have STP properly configured with the following tp-link switches.

T2600G-52TS - Primary Switch - CIST Priority = 4096  (SONOS Music Players and Zappiti Media Players)

T2600G-28TS - Remote Switch #1 - CIST Priority = 8192 (SYNOLOGY DS1821+ NAS - Music and Movie Files)

TT2500G-10T - Remote Switch #2 - CIST Priority = 8192

 

TL-SG3210 - Remote Switch #3 - CIST Priority = 8192

1. SONOS requires STP which I have configured on all switches.

2. All switch ports that connected to the SONOS components are configured with STP Enabled and STP Path Cost = 10.

3. All interlink tp-link switch ports between the Primary and Remote Switches have STP Enabled and STP Patch Cost = 4.

4. All ports that have equipment connected that do NOT require STP have STP disabled in the switch configuration.

5. I have the CIST Priority configured as listed above. My goal is to insure that the T2600G-52TS is the ROOT BRIDGE. I am not sure if I have the CIST Priority configured correctly on the Remote Switches. Should each switch have a different priority.

 

I look forward to comments and suggestions about my configuration.

It's hard to say without information on the topology.

if all remote switches are only connected to the primary switch it will work.

 

If e.g. the remote switch #3 is connected to #1 and #2 (and #1 and #2 connected directly or via primary switch) the setup is not optimal, because all remote switches have the same priority.

 

Also, the path costs seem to be very low. Standard values are 200000 for 100Mbit, 20000 for Gigabit and 2000 for 10G links. If you keep your settings consistent, it's fine, but the switches also allow automatic setting of the costs and then your numbers might result in a less efficient setup.

Yes, all of the remote switches are directly connected to the T2600G-52TS which is the primary Ethernet Switch. The path costs are low since the SONOS hardware uses are older STP standard. The suggested path costs have been provided by them.
