Configuring FlexLinks and the MAC Address-Table Move Update
How to Configure the FlexLinks and MAC Address-Table Move Update
Configuring a Preemption Scheme for FlexLinks
Configuring VLAN Load Balancing on FlexLinks
Command Purpose
1. configure terminal Enters global configuration mode.
2. interface interface-id Specifies the interface, and enter interface configuration
mode. The interface can be a physical Layer 2 interface
or a port channel (logical interface). The port-channel
range is 1 to 10.
3. switchport backup interface interface-id Configures a physical Layer 2 interface (or port channel)
as part of a FlexLinks pair with the interface. When one
link is forwarding traffic, the other interface is in standby
mode.
4. switchport backup interface interface-id preemption
mode [forced | bandwidth | off]
Configures a preemption mechanism and delay for a
FlexLinks interface pair. You can configure the
preemption as:
 forced—The active interface always preempts the
backup.
 bandwidth—The interface with the higher bandwidth
always acts as the active interface.
 off—No preemption happens from active to backup.
5. switchport backup interface interface-id preemption
delay delay-time
Configures the time delay until a port preempts another
port.
Note: Setting a delay time only works with forced and
bandwidth modes.
6. end Returns to privileged EXEC mode.
Command Purpose
1. configure terminal Enters global configuration mode.
2. interface interface-id Specifies the interface, and enters interface configuration
mode. The interface can be a physical Layer 2 interface
or a port channel (logical interface). The port-channel
range is 1 to 10.
3. switchport backup interface interface-id prefer vlan
vlan-range
Configures a physical Layer 2 interface (or port channel)
as part of a FlexLinks pair with the interface, and
specifies the VLANs carried on the interface. The VLAN
ID range is 1 to 4096.
4. end Returns to privileged EXEC mode.
