2 Interfaces You can configure and monitor physical interfaces (Ethernet), port-channels, and VLANs in L2 or L3 modes. Table 1. Interface types Interface type Ethernet (PHY) Management Loopback Port-channel VLAN Supported / default mode L2, L3 / unset N/A L3 / L3 L2, L3 / unset L2, L3 / L3 Requires creation / default status No / no shutdown (enabled) No / no shutdown (enabled) Yes / no shutdown (enabled) Yes / shutdown (disabled) Yes (except default) / shutdown (disabled) Ethernet interfaces Ethernet port interfaces are enabled by default. To disable an Ethernet interface, enter the shutdown command. To re-enable a disabled interface, enter 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 All physical, Ethernet and port-channel interfaces use a single MAC address and, by default, 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. You can 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 multiple (two or more) VLANs. A trunk interface carries VLAN traffic that is tagged using 802.1q encapsulation. If an access interface receives a packet with an 802.1q tag in the header that is different from the access VLAN ID, it drops the packet. 72 Interfaces
