Cannot enter command

[Arimo]

Hi Angus

... there's one obvious question unasked.

"Invalid input" means you're trying to give a command which the switch doesn't recognize. So what exactly do you do to get this error, and in what context?

Just curious...

Show Run command:

speed-duplex 10-half
exit
interface C11
speed-duplex 10-half
exit
interface C12
speed-duplex 10-half
exit
trunk A4,B4 Trk10 LACP

Hi again

so when you enter command "show run" you get a partial output, which ends at "Invalid input"?

Ok,
a4 and b4 are part of the trunk trk10 and trk10 already isn't an edge-port.
if an port is an member of an trunk you simple can't configure just one of the trunkports to be or not to be an edge-port. you would configere both at the same time with:
no spanning-tree trk10 edge-port
from your picture that already happend!
thats all.

no spanning-tree C10 edge-port
no spanning-tree C11 edge-port
no spanning-tree C12 edge-port
no spanning-tree C13 edge-port
no spanning-tree C14 edge-port
no spanning-tree C15 edge-port
no spanning-tree C16 edge-port
no spanning-tree Trk10 edge-port
spanning-tree Trk10 priority 4
spanning-tree priority 0

You can see the configuration is already there: no spanning-tree Trk10 edge-port

[EckerA]

exactly,
thats what i tried to tell you..
and your question why it is trk10:
that isn't the default. it is configured as you can see in your sh run
trunk a4,b4 Trk10 lacp
but it is always Trkxx with xx beeing 10 in your config.
