12 RecoverRing II™ Configuration
66
1. Two directly connected rings cannot have the same Ring ID .
2. Within a ring, only one switch can be set as Coupling Primary , and the other one as
Coupling Backup .
3. Within the same level ring, more than one switch can be set as Dual homing .
The bottom part of this page lists the configuration of two coupling rings.
Caution:

Coupling control port cannot be the same with primary port or secondary port.

A port with STP enabled cannot act as coupling control port.
12.3 RecoverRing II™ Timer
This page sets RecoverRing II™ timer configurations: HelloTime, FailTime, FastHelloTme
and FastFailTime.
HelloTime
：
Sets hello time of the switch. It is in the range of 1 to 10 seconds. The default
value is 1 second.
FailTime: Sets fail time of the switch. It is in the range of 3 to 30 seconds, and the default
value is 3 seconds.
FastHelloTime : Sets fast hello time of the switch. It is in the range of 10 to 500 milliseconds,
and the default value is 10 milliseconds.
FastFailTime: Sets fast fail time of the switch. It is in the range of 30 to 1500 milliseconds.
The default value is 30 milliseconds.
These timer values are used in master node. When the hello timer times out, the master node
will send out a hello packet. If the fail timer times out, it indicates that a link failure has
occurred in the ring.
If Fast detection status in RecoverRing II™ tab page is enabled, the master node will use
the FastHelloTime and FastFailTime instead of HelloTime and FailTime to set the hello
timer and fail timer.
