Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Ethernet and port-channel interfaces are in L2 access mode by default. When you disable the L2 mode and then assign an IP address to an Ethernet port interface, you place the port in L3 mode.

Configure one primary IP address in L3 mode. You can configure up to 255 secondary IP addresses on an interface. At least one interface in the system must be in L3 mode before you configure or enter a L3–protocol mode, such as OSPF.

1. Remove a port from L2 switching in INTERFACE mode.

   no switchport

2. Configure L3 routing in INTERFACE mode. Add secondary to configure backup IP addresses.

   ip address address [secondary]

3. Enable the interface for L3 traffic transmission in INTERFACE mode.

   no shutdown
