Interface spanning tree change confirmation ?

Extreme_Learner — Tue, 22 Jun 2021 14:40:41 GMT

Apologies if this a stupid question. I am changing the config on some of the ports on our core VSP switches and I think I have this right but I would like some confirmation if someone could help?

Current port config :-

spanning-tree mstp edge-port true

What I am intending on changing to :-

no spanning-tree mstp force-port-state enable

Message When issuing the commands:-Disabling CIST would also disable all other MST instances.Are you sure you want to continue (y/n) ?

From what I’ve read this is correct and I should choose Y however I wanted to confirm this would not effect any other ports when I do this ?

Thanks for any help

If you run the command while being under the interface mode then it will only affect that particular port and not the complete switch.

Thankyou for the previous answer. I’m left slightly perplexed as i thought it would change the spanning tree on the port however it seems left with it both on and off in the config ?

interface GigabitEthernet 1/10

slpp packet-rx-threshold 75
