HG and spantree
When configuring the HG "lostless" network, we forgot to disable the spantree on network equipment. To enjoy a fully redundant double attach network, the spantree should be disabled. The same thing when we update the network equipment.
We will then disable the spantree. There will be a small cut of approximately 15 seconds on the double attach at the time that the network deactivates spantree on each port. We must take the equipment serial cable for this intervention and avoid losing hand.
Here we go.
