Enabling portfast on trunk connection

[s3988111]

Hi I'm pretty new to network and was wondering is it possible to enable portfast on the usable ports in this topology. If can then please show me how to do it. Thanks!

Hi

 The command is as follow:

Altona_SW(config)#int Fa0/10

Altona_SW(config-if)#spanning-tree portfast

%Warning: portfast should only be enabled on ports connected to a single

host. Connecting hubs, concentrators, switches, bridges, etc... to this

interface when portfast is enabled, can cause temporary bridging loops.

Use with CAUTION

%Portfast has been configured on FastEthernet0/10 but will only

have effect when the interface is in a non-trunking mode.

Altona_SW(config-if)#

But the interface must be Access Interface, as you can see on the warning.
