FlexLink+ Preemptive configuration

[Ma'moun Mohammad shanableh]

Dears,

I have the following configuration done for backup interfaces (FlexLink+), my question is that does this feature support automatic preemption for the primary and secondary interfaces?

As when i enable the primary port by no-shut the link from the other end, it does not restore the "Open" state, and the secondary stays the "Open" port.

!
interface GigabitEthernet1/1/1
switchport trunk allowed vlan 310,350
switchport mode trunk
rep segment 1 edge no-neighbor primary
end
!
interface GigabitEthernet1/1/2
switchport trunk allowed vlan 310,350
switchport mode trunk
rep segment 1 edge no-neighbor preferred
end

The only thing they say, is that the feature is deprectaed!!!

How is that possible, as still we are able to configure it using the "rep" commands, and as shown in the document shared by you earlier???

Actually, i have implemented the following command instead and it it worked:

event manager applet Interface-UP
event syslog pattern "%LINK-3-UPDOWN: Interface GigabitEthernet1/1/1, changed state to up"
action 5.0 cli command "enable"
action 5.1 cli command "conf t"
action 5.2 cli command "interface g1/1/2"
action 5.3 cli command "shut"
action 5.4 cli command "end"

event manager applet interface-Down
event syslog pattern "%LINK-3-UPDOWN: Interface GigabitEthernet1/1/1, changed state to down"
action 5.5 cli command "enable"
action 5.6 cli command "conf t"
action 5.7 cli command "interface g1/1/2"
action 5.8 cli command "no shut"
action 5.9 cli command "end"
