LACP Best Practice Configuration

[TOM FRANCHINA]

We need to set up an LACP Port Channel to connect to an EMC Datamover. What would be the best practice configuration. I have found 2 in my research: Should we use switchport mode trunk or switchport mode access. 

First:

interface Port-channel1
  switchport access vlan 60
  switchport mode access
!
interface GigabitEthernet1/0/46
 switchport access vlan 60
 switchport mode access

channel-protocol lacp
 channel-group 1 mode active

Second

interface Port-channel3
switchport trunk allowed vlan 60
switchport mode trunk
!
interface FastEthernet0/23
switchport trunk allowed vlan 60
switchport mode trunk
channel-protocol lacp
channel-group 3 mode active

If you know you are never going to add a second vlan to the link, first scenario is good enough.  If you think you may want to add a second vlan to the same link in the future, you want to trunk it now so in the feature you can always add more vlans to it and no need for down time (second scenario).

Reza,

The switch is a single vlan for one application. I will use the first configuration.

Thanks very much for the quick response!!!!!
