3 Interfaces You can configure and monitor physical interfaces (Ethernet), port-channels, and virtual local area networks (VLANs) in Layer 2 (L2) or Layer 3 (L3) modes. Table 1. Interface types Interface type Supported Ethernet (PHY) L2, L3 Management N/A Loopback L3 Port-channel L2, L3 VLAN L2, L3 Ethernet interfaces Default mode unset N/A L3 unset L3 Requires creation No No Yes Yes Yes, except default Default status no shutdown enabled no shutdown enabled no shutdown enabled no shutdown enabled no shutdown enabled Ethernet port interfaces are enabled by default. To disable an Ethernet interface, use the shutdown command. To re-enable a disabled interface, use the no shutdown command. 1 Configure an Ethernet port interface from Global CONFIGURATION mode. interface ethernet node/slot/port[:subport] 2 Disable and re-enable the Ethernet port interface in INTERFACE mode. shutdown no shutdown Disable Ethernet port interface OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# shutdown Enable Ethernet port interface OS10(config)# interface ethernet 1/1/1 OS10(conf-if-eth1/1/1)# no shutdown L2 mode configuration Each physical Ethernet interface uses a unique MAC address. Port-channels and VLANs use a single MAC address. By default, all the interfaces operate in L2 mode. From L2 mode you can configure switching and L2 protocols, such as VLANs and Spanning-Tree Protocol (STP) on an interface. Enable L2 switching on a port interface in Access or Trunk mode. By default, an interface is configured in Access mode. Access mode allows L2 switching of untagged traffic on a single VLAN (VLAN 1 is the default). Trunk mode enables L2 switching of untagged traffic on the Access VLAN, and tagged traffic on one or more VLANs. By default, native VLAN of a port is the default VLAN ID of the switch. You can change the native VLAN using the switchport access vlan vlan-id command. Interfaces 85
