What exactly is your problem?

The Network Switch Router wizard will scan the switch and can find "ports" like VLAN interfaces which really aren't interfaces. Does this sound like your problem?

Hi Box293,

My problem is this cisco router only has 2 Gi interface. but Nagios detected 3 Gi interface. And I cannot identify which interface is wrong 1. Can anyone guide me on this?

Thanks in advance.

Can you post a partial or full output of 'show run' from the switch? I'd like to see the part pertaining to your interface configuration to see how they line up.

Do you feel int 0/0/0 is the extra interface? Obviously from the screenshot it is listed as up. So far I do not see anything awry on the Nagios side of the fence.

HI ,

Thanks for replay, here you can see that Nagios detected GigaEthernet0/0, 0/1,0/2...but in the router I only have GigaEthernet 0/0. 0/1 only. How I can find out the interface description.

Thanks in advance.

In you screen capture when you ran show interface brief, there are more than 2 interfaces shown.
You can change the Wizard to use the Port Name, is that what you want to do?

Hi all,

Thanks for reply, Yes I changed the wizard to scan by use the port name. Somehow, In my router only have GigaEthernet 0/0, 0/1 and 0/0/0 , 0/0/1, 0/0/2, 0/0/3. But Nagios detected GigaEthernet 0/0, 0/1, 0/3 and 0/0/0 , 0/0/1, 0/0/2, 0/0/3. Do anyone know the GigaEthernet 0/3 is what??

Thanks in advance.
