Routed Port in Vlan

[Raimund Schimanovits]

How can i make a crosslink by 2 routed ports. The switchport in the router has vlan1 and the routed port cannot ping the vlan1 ip. On the other router i had the same interfaces.

How can i add the routed port to the vlan1 ??? So the port should act as a switchport.

Thanks

[John Blakley]

Can you post your configs?

HTH,

John

The interface GigabitEthernet1/0 should be in the vlan1 but i cannnot ping the vlan1 interface from GigabitEthernet1/0.

Why?

Thanks

Hi,

Interface gi 1/0 is not a switchport it  is routed port, so must have an IP address.

[Raimund Schimanovits]

Yes this is my problem. Can i change it to an switchport that is in vlan1????

[John Blakley]

Try this:

int g1/0

switchport

switchport mode access

switchport access vlan 1

HTH,

John

i have only this commands in my interface

I can only assume the g1/0 is a L3 port then and you won't be able to change that. You may need to move to one of the other g0/3/? ports and that should resolve the issue...

** Edit **

I looked over your inventory, and this is a 2921. So, I'm also assuming that you have hwics in the router that allow you to configure switching. That being said, your 2 switch modules are 0/1 and 0/3. The g1/0 is going to be the L3 port that would only be able to be configured as a L3 interface and not a member of vlan 1. You will need to move your connection to the switching module...

HTH,

John

[Raimund Schimanovits]

So the crosslink by the switchport is working but i want to take the fiber connection for that. So can i change the L3 g1/0 fiber port to a switchport connected to vlan1 or not?

The fiber is much more faster than the switchport.

Is this possible or not? I don´t know how to change a L3 interface to a L2 interface connected to a vlan.

Thanks

Raimund

Hi

to get round this just give int Gi 1/0 an IP address say 10.0.0.3 255.255.255.0 and make that address the default gateway on the switch as I assume the router is connected to the Internet or the rest of your network.

[Richard Bradfield]

Raimund,

The simple answer is NO

[saif musa]

How can i add the routed port to the vlan1 ??? So the port should act as a switchport

Fine below....

switch(config)# interface fastethernet 0/x      (( example))

switch(config-if)# switchport mode access

switch(config-if)# switchport access vlan1

switch(config-if)# end

switch# write

switch# exit

Regards

[Raimund Schimanovits]

Sorry but the command is not available in my interface.

[saif musa]

Which one is not available inside your switch ??

[Raimund Schimanovits]

The switchport command is not avialable in my interface GigabitEthernet1/0.

So it is a Layer 3 port and i would connect it to vlan1. Is this possible? With witch command?

Thanks
