6.16 Xpress Ring

The Xpress-Ring is a fast-acting, self-healing ring recovery technology that enables networks to
recover from link failure within 10ms.
Fast Link Recovery and Ring Redundancy are important features for increasing the reliability of
non-stop systems.
If the network is planned correctly with an arbiter Switch and ring ports, the network will recover
from any segment failure within a very short time.
There are two roles (Forwarder and Arbiter) of the Switch in the Xpress-Ring. There is one and
only one Switch is the Arbiter Switch and the others are the forwarder Switch.
One of the ring ports of the Arbiter Switch will be set to blocking state. When one of the ring
connections is broken, the blocked port will be set to forwarding state.
Notices:
An Xpress Ring can have one Arbiter only.

A Switch can join one or two Xpress Ring.

Every Switch can be a Forwarder or Arbiter in an Xpress Ring.

The two adjacent Xpress Rings should not use a same destination multicast MAC.

If you want to enable the STP (RSTP) and Xpress Ring on a Switch, you should disable

the STP (RSTP) on the Xpress Ring's member ports.
If you want to enable the Loop Detection and Xpress Ring on a Switch, you should

disable the Loop Detection on the Xpress Ring's member ports.
If you want to enable the Broadcast Storm and Xpress Ring on a Switch, you should

disable the Broadcast Storm on the Xpress Ring's member ports.
If there are old devices (for example: INS-803A) to join the Xpress-Ring, they can join

as a forwarder only.
