4.3.9.3.2.1 Configure RapidRing

Each switch must be configured for ring operation. The console screen of Figure 35

displays the RapidRing default screen settings. There are three options to consider:

• Ring Status enables or disables RapidRing functionality. Every switch in a ring

must have this option enabled. Otherwise, the presumed backup protection will

not exist because a link failure might not be reported to the master.

• Switch Mode sets the master/slave status of the switch being configured. Only

one master is defined per ring. Otherwise, the ring will not be established, some

signal paths may not exist and messages could be lost.

• Ring ID must be a value from 1 – 100. The default value of 1 assumes that only

one ring exists. If more rings are defined, each switch must be properly assigned

to its Ring — otherwise, messages might be lost. When configuring multiple

rings, all switches in a particular ring must have matching Ring ID values.

In addition to the three options described above, a read-only Network Status field

reports the condition of the ring. The three following conditions are reported:

• Ring Not Available is displayed when RapidRing is not enabled.

• Ring Incomplete is displayed when RapidRing is enabled, but the master has

invoked the backup link due to a primary ring failure.

• Ring Complete is displayed when RapidRing is enabled and all links are intact.
