5.15.6 Flex-link configuration
Flex-link is a redundancy function that secures the reliability of data communication channel. A flex-
link can contain Ethernet and port-channel interfaces. One of these interfaces is in blocked state; it starts
forwarding traffic only when there is a failure on another interface.
Ethernet interface configuration mode commands, port group interface
Command line request in Ethernet interface, port group interface configuration mode appears as
follows:
console(config-if)#
Table 5.95 —Ethernet interface configuration mode commands, port group
Command
Value/Default value
Action
flex-link backup
{tengigabitethernet te_port |
gigabitethernet gi_port |
portchannel port_channel}
te_port: (1..8/0/1..4);
gi_port: (1..8/0/1..24);
port_сhannel (1..12)/-
Enables flex-link on the interface and specifies the backup role for
the selected interface in a pair.
no flex-link backup
{tengigabitethernet te_port |
gigabitethernet gi_port |
portchannel port_channel}
Disables flex-link on the interface and removes configured
interface from flex-link pair.
flex-link preemption mode
[forced | bandwidth | off]
-/off
Specifies action upon establishing an interface participating in flex-
link:
- forced—if the established interface is configured as master, it
will become active.
- bandwidth—upon establishing an interface, the interface with
the highest bandwidth will become active.
- off—established interface will remain in a locked state.
no flex-link preemption mode
Restore the default value.
flex-link preemption delay
delay
delay: (1..300)/35
When disabled port status changes to 'up', specifies the amount of
time that should pass for an action set by flex-link preemption
mode command to be executed.
no flex-link preemption delay
Restore the default value.
Privileged EXEC mode commands
Command line request in privileged EXEC mode appears as follows:
