L3 mode configuration
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 L3protocol 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

Fibre Channel interfaces
OS10 unified port groups support FC interfaces. A unified port group operates in Fibre Channel or Ethernet mode. To activate
FC interfaces, configure a port group to operate in Fibre Channel mode and specify the port speed. By default, FC interfaces are
disabled.
S4148U-ON
On a S4148U-ON switch, FC interfaces are available in all port groups. The activated FC interfaces depend on the currently
configured port profile. For more information, see S4148U-ON port profiles.

MX9116n Fabric Switching Engine
On an MX9116n Fabric Switching Engine module, FC interfaces are available only in unified port groups 15 and 16, ports 43 and
44.
