There is no no version.
See link failover force.
Use to specify the time that the router waits for a port on a GE I/O module to become
active before the router switches to the redundant port.
Select an interface on the GE I/O module before you issue this command.
Specify a time in the range 100–10,000 ms.
Example
host1(config)#interface gigabitEthernet 5/0
host1(config-if)#link failover timeout 1000
Use the no version to restore the default situation in which the router sets this time
automatically.
See link failover timeout.
Use to disable redundancy on a GE I/O module by allowing operation on the specified
port only.
Select an interface on the GE I/O module before you issue this command.
Example
host1(config)#interface gigabitEthernet 5/0
host1(config-if)#link selection secondary
Use the no version to restore the default situation in which port redundancy is enabled.
See link selection.
This section describes the options for configuring Ethernet interfaces.
You configure an Ethernet interface based on the requirements for your router
configuration and the protocols you plan to route on the interface. Because you can
configure an interface in different ways, Ethernet configuration tasks are divided into
three primary areas. These areas are further described in separate sections in this chapter.
Configuring the physical interface—You must perform basic configuration steps for all
interfaces. This task begins with selecting an Ethernet interface and setting parameters
such as line speed and MTU.
Configuring VLANs and stacked VLANs (S-VLANs)—After you configure the physical
interface, you must decide whether to configure the Ethernet interface with or without
VLANs or S-VLANs. VLANs and S-VLANs enable you to multiplex multiple IP interfaces
and PPPoE interfaces over a single physical Ethernet port. If you are not configuring
with VLANs or S-VLANs, proceed to "Configuring Ethernet Interfaces" on page 167.
