Changing configurations from delay-restore orphan port to delay-restore port and vice-versa
If you want to change configuration from delay-restore orphan port (VLT) to delay-restore port (non-VLT), the system
would throw error even if the delay-restore port configuration is done on an interface where no delay-restore orphan port
configurations are present. You must first remove all the delay-restore orphan port configurations from all interfaces and then
configure delay-restore port. For changing configuration from delay-restore port to delay-restore orphan port, the same steps
should be taken.
The configurations and behavior of this feature for VLT and non-VLT are different and mutually exclusive. Meaning, only
one of the delay-restore port configurations or delay-restore orphan port configurations can be present in a system at a
time. If delay-restore port is configured on few interfaces earlier and now delay-restore orphan port needs to be configured,
delay-restore port configurations must be removed from all ports first. Otherwise, delay-restore orphan port configuration will
be rejected with error message.
If delay-restore orphan ports are configured in the system and if VLT domain is removed, delay-restore orphan ports commands
is considered to be inactive; the delay-restore timer is not applied for orphan ports. After the VLT domain is configured back,
the command becomes active again on the configured interfaces.
