Hi,
it´s a little bit confused ! What´s the difference between Int 2/2 and 2/3 ??
best regards!
Cat WS-C4506; IOS Version 12.1(19)EW1; SupIV WS-X4515
Module2 18Port GigaBit WS-X4418-GB
C4506(config)int gig 2/2
C4506(config-if)#switchport trunk encapsulation dot1q
C4506(config)#int gig 2/3
C4506(config-if)#switchport trunk encapsulation dot1q
^
% Invalid input detected at '^' marker.
C4506#sh int trunk module 2
Port Mode Encapsulation Status Native vlan
Gi2/2 on 802.1q not-trunking 1
Gi2/3 on 802.1q not-trunking 1
C4506#sh run int gig 2/2
Building configuration...
Current configuration : 187 bytes
!
interface GigabitEthernet2/2
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,938,942
switchport mode trunk
logging event link-status
end
C4506#sh run int gig 2/3
Building configuration...
Current configuration : 149 bytes
!
interface GigabitEthernet2/3
switchport trunk allowed vlan 1,938,942
switchport mode trunk
logging event link-status
end
Solved! Go to Solution.

this is a limitation with the ws-x4418. supports trunking only on ports 1 and 2 because the
ports are fully independent, nonblocking Gigabit Ethernet. All the rest of the ports are multiplexed in four groups of four ports

Please provide a more detailed explanation of the problem. It is not clear what the question is.
From the info provided, you are asking what the difference is between ports 2 and 3 on a ws-x4418 module and I'm sure that's not what you are asking.
Thanks.

The problem is that there are no difference between the two interfaces, but at port 3 I can´t enter the command "switchport trunk encapsulation dot1q" > "% Invalid input detected at '^' marker" and at port 2 I can enter it normally. However the configuration of both trunks (sh int trunk module 2) are OK, but there is no entry in the running-config of port 3 !!!

Hmm... I think a vital clue is where it is saying your input is bad, its acting like the prompt "C4506(config-if)#" is part of the command. The "^" that tells where the bad input is appears to be on the "C" of the C4506. Strange...

The marker is displaced. Original it´s at the (e)ncapsulation !!! If I type a "?" after the "switchport trunk", there is no "encapsulation" entry !!!

Module X4418 is not fully support ISL trunk protocol.
Port 1 and 2 support ISL / Dot1q.
That was why you can use "switchport trunk encaptulation dot1q"
Port 3 to 18 only support dot1q
That was why there is no command entry of "switchport trunk encaptulation XXXX "
