Solved: when "show interfaces status" find that vlan column is routed

what does routed mean?

A routed port is a physical port that acts like a port on a router; it does not have to be connected to a router. A routed port is not associated with a particular VLAN, as is an access port. A routed port behaves like a regular router interface, except that it does not support VLAN subinterfaces. Routed ports can be configured with a Layer 3 routing protocol.

Configure routed ports by putting the interface into Layer 3 mode with the no switchport interface configuration command. Then assign an IP address to the port, enable routing, and assign routing protocol characteristics by using the ip routing and router protocol global configuration commands.

Hope that helps

Routed or Layer 3 port.

Just to confirm, does that mean that subinterfaces can NOT be created on a routed port on a multilateyer switch?

Hi,

The answer will be it depends, and the dependencies could be hardware platform, OS version, module type (if chassis based switch) etc.

The above text appears to have been taken from the Routed Ports section of the Catalyst 3850 IOS-XE configuration guide so is true for that platform and that OS.

By contrast the Catalyst 6500 has supported routed sub-interfaces for many years. The configuration, and restrictions, associated with this are shown in the Layer 3 Interface Configuration section of the software configuration guide for that platform.

As with many things, check the release notes and configuration guides for the platform you're interested in.

Regards

Routed means Layer 3.

Switchport means Layer 2.
