Flex-link function 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:

}
gi_port: (1..4/0/1..28)/-;
fa_port: (1..4/0/1..24)/-;
port_сhannel: (1..8)/-
Enables flex-link on the interface and specifies the backup role
for the selected interface in a pair.
no flex-link backup {
gigabitethernet

}
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.
