I'm trying to understand RSPT and I had setup a small network lab with 4 Catalyst access switches. I provide a small schema of my lab setup. I wrote on the schema where I was expected and see root port, designated and alternated port.
But when I disconnect a topology change I see the topology converge very quickly. When I reconnect previously disconnected cables the spanning tree algorithm does not reconverge correctly and each tine I see 1 port place in error disable stateâ¦. I should each time reenable port manually to make spanning tree return to his original topology.
At the first time I was setup each connection with etherchannel configuration, because I was have some problems to my topology reconvergence after returning to originale state, I decide to connect one one cable in each etherchannel (avoiding problem with etherchannel it-self ) but same thing appendâ¦
Can someone help me ??
