I came across this command at a Layer 2 Switch, and I don't know what it does.

no switchport
Ip Addr

1 Answer 1


This would have to be commands provided from an interface on a L3 capable switch.

The no switchport command puts the interface in L3 mode (known as "routed port") and makes it operate more like a router interface rather than a switch port. The ip address command assigns an IP address and network mask to the interface. Routed ports can be configured with a Layer 3 routing protocol.

However, restrictions apply:

  • It does not support VLAN subinterfaces.
  • It does not support Layer 2 protocols, such as DTP and STP.
  • It is supported only on switches running the IP base or IP services image.
  • Thanks YLearn, When I saw the picture I couldn't imagine which it will be a L3
