I have a question about the RSTP ethernet swtiches, I have 40 RSTP ethernet switches, they connect with the line topology and root birdge is 23th device on the line. I am using just 23 device for this test:
HelloTime = 2 Remaining Hops = 20 Forward Delay = 15 Max Age = 20
If I connect the topology like that
23th-22th-21th-....2th-PC I couldnt access 3th,4th,5th until 23th if I remove the 1 device on the network, so if I remove the 2th device, we have 20 device so I could access every device. When the topology have more than 20+ device until root bridge I couldnt access. So I connect
23th-22th-21th-...2th-PC again and changed to Max Age to 21 instead of 20, I could access evry device. Is there logical ? What is the real reason for ?
