4.4.9.3.4 Configure RapidRing
Each switch in a ring must be configured for ring operation. The screen of Figure 38
displays the default screen settings. There are four parameters 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.
Ring State 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 the range of 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.
Figure 38 — Configure RapidRing
In addition to the three options described above, a 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.
