Usage Information Pre-configuring the interfaces for the optical module preserves the configuration if/when an optical module is removed. The optional 10G optical module is automatically recognized and the interfaces are created when the module is inserted into the slot. However, if the system is not already configured for the interfaces, when the module is removed the interfaces and their configurations are removed as well. switchport c e s Place the interface in Layer 2 mode. Syntax switchport [backup interface {gigabit | tengigabit} slot/port] To remove the interface from Layer 2 mode and place it in Layer 3 mode, enter no switchport. If a switchport backup relationship exists, remove that relationship first. To remove a switchport backup relationship created on this port, enter no switchport backup interface {gigabit | tengigabit} slot/port]. Parameters backup interface gigabit tengigabit slot/port Use this option to configure a redundant Layer 2 link without using Spanning Tree. This keyword configures a backup port so that if the primary port fails the backup port changes to the up state. If the primary later comes up, it becomes the backup. Enter this keyword if the backup port is a 1G port. Enter this keyword if the backup port is a 10G port. Specify the line card and port number of the backup port. Defaults Disabled (The interface is in Layer 3 mode.)

Introduced on E-Series ExaScale Added backup interface option. Introduced on S-Series Introduced on C-Series Introduced for E-Series Usage Information If an IP address or VRRP group is assigned to the interface, you cannot use the switchport command for that interface. To use the switchport command on an interface, only the no ip address and no shutdown statements must be listed in the show config for that command. When you enable the switchport command, the interface is automatically added to the Default VLAN. To use the switchport backup interface command on a port, first execute the switchport command on the port.
