API Guide

By default, a trunk interface carries only untagged traffic on the Access VLAN. You must manually configure other VLANs for
tagged traffic.
1. Select one of the two available options:
● Configure L2 trunking in INTERFACE mode and the tagged VLAN traffic that the port can transmit. By default, a trunk
port is not added to any tagged VLAN. You must create a VLAN before you can assign the interface to it.
switchport mode trunk
switchport trunk allowed vlan vlan-id-list
● Reconfigure the access VLAN assigned to a L2 access or trunk port in INTERFACE mode.
switchport access vlan vlan-id
2. Enable the interface for L2 traffic transmission in INTERFACE mode.
no shutdown
L2 interface configuration
OS10(config)# interface ethernet 1/1/7
OS10(conf-if-eth1/1/7)# switchport mode trunk
OS10(conf-if-eth1/1/7)# switchport trunk allowed vlan 5,10
OS10(conf-if-eth1/1/7)# no shutdown
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 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
L3 interface configuration
OS10(config)# interface ethernet 1/1/9
OS10(conf-if-eth1/1/9)# no switchport
OS10(conf-if-eth1/1/9)# ip address 10.10.1.92/24
OS10(conf-if-eth1/1/9)# no shutdown
View L3 configuration error
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ip address 1.1.1.1/24
% Error: remove Layer 2 configuration before assigning an IP
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.
