CFG H3 Sec 1.1: No Switch may generate a TC when any access port goes down.

There is point in Sec 1.1 of H3 CFG:
None of the switches may generate a TC when any of the access port goes down.

What do we have to do for this ?
Is there any specific command to achieve this requirement.

Does this command has anything to do with this requirement:
no spanning-tree mst simulation post global

Avoid TCN Generation with the portfast Command

The portfast feature is a Cisco proprietary change in the STP implementation. The command is applied to specific ports and has two effects:
Ports that come up are put directly in the forwarding STP mode, instead of going through the learning and listening process. The STP still runs on ports with portfast.
The switch never generates a TCN when a port configured for portfast goes up or down.- speaks to "None of the switches may generate a TC when any of the access port goes down"

Thanks cc13093:

So is the following command sufficient:
spanning-tree portfast edge default
