Portfast question

Futura

Ok so you can either set a whole switch to portfast by:

Switch(config)# spanning-tree portfast default

and also set up specific port to portfast by

Switch(config-if)# spanning-tree portfast

and this also works for a range but, my question is this:

Would the global command cause a problem if the switch already has two trunks set up to another switch?

I have enabled the global command and it did not seem to cause a problem with the existing stp. Or is there a command to set of the specific ports after the global portfast setting has been enabled.

Many thanks.

Global portfast default, once applied - only applies to ports configured as access ports.

'switchport mode access' or that have negotiated access port state, if you've only applied the 'switchport access vlan [number]'.

It will not affect trunks.

Just as an extra you can also apply portfast and set an interface to access mode using the following macro:

e.g

conf t
int f0/10
switchport host
