Issues Changing Cisco Port to Switchport

Hello Experts,

When I paste the following config (see at end of discussion) I keep on getting the error message 'Command rejected: Not a switchable port'

interface Port-channel2

 switchport

 switchport trunk encapsulation dot1q

 switchport mode trunk

 no shutdown

Router(config)#interface Port-channel2

Router(config-if)# switchport

Command rejected: Not a switchable port.

Then when I enter configure the actual interface I get the following error:

Router(config-if)#int eth 1/1

Router(config-if)#interface Ethernet1/1

Router(config-if)# switchport

Router(config-if)# switchport trunk encapsulation dot1q

Router(config-if)# switchport mode trunk

Router(config-if)# duplex auto

 

Router(config-if)# channel-group 2 mode passive

Command rejected (Et1/1): Either port is L2 and port-channel is L3, or vice-versa

Now, this occurs only when I paste the entire config as follows:

!

hostname ALS1

!

boot-start-marker

boot-end-marker

!

!

!

no aaa new-model

!

ip cef

I should mention that the configs work fine when I built them from scratch. I only have problems when pasting the whole configs in one shot.

My guess is that switch doesn't like the port-channels to be pasted in before the actual configs for the actual interface - but thats just a wild guess.

Can you please shed some light on the situation?

Cheers

Configure the trunking on the physical interfaces and put those interfaces into the port-channel group.

jesper,

I think the problem was the fact that when pasting the configs I was pasting the configs for the logical interfaces before the configs for the actual interfaces

Jan SpringerCommented:
sure but you still don't need to define that information within the logical interface.

Nayyar HH (CCIE RS)Network ArchitectCommented:
The command "channel-group 4 mode passive" creates the logical interface

After which the logical interface would inherit relevant configurations from the physical interfaces.

Onwards Going forward logical/topology changes are made to the logical interface.
