3750 - Verify if IP routing is on/off?

[Eric Snijders]

So, we have a 3750. In the running config it doesn't show the "ip routing" command anywhere, but it does have have a routing table (mostly statics). Is routing only enabled with the "ip routing" command in the running config?

With the 3750 you usually do have to enable it. 

Does it route between clients in different vlans or not ?

Hi

In order to use Layer 3 capabilities you need to execute: Ip routing, globally. Now if your devices is working like Layer 2 you will not able to execute this command: show ip route, and you will receive a message like: 

% Invalid input detected at '^' marker.

Also on Layer 2 mode, you will not able to convert a port to layer 3, you will receive the following message:

no switchport
Command rejected: not allowed on this interface.

Now if you want to verify it on the configuration, you can execute:

show run | begin ip routing 

Hope it is useful.

your CLI command should be

show run all | begin ip routing

show run does not return default settings and you need that to get the ip routing status.
