Cisco Command : What is the difference between switchport mode trunk from switchport trunk allowed vlan all?
does "switchport mode trunk" command allow all vlan by default or I do I need to issue "switchport trunk allowed vlan all" ?
Switches / Hubs

switchport mode trunk makes an interface a trunk port (can carry multiple VLANs).
By default, all VLANs are allowed on a trunk port.
So no, you do not need to issue a "switchport trunk allowed vlan all". Unless a prior command was issued to restrict the allowed VLAN's.
from show run command, this is what I'm seeing on the interface.
Switchport trunk allowed vlan 1,10
switchport mode trunk
Does this allow only vlan 1 and 10 or does it allow all vlans because of the command "switchport mode trunk"?
