4.4.9.3.2 RapidRing and Other Management Features

As a rule, when the RRPs are used for the RapidRing, they should not be involved with

other management features. Specific issues are described below.

Port Parameters — If RapidRing is enabled, port options (Figure 11, upper panel) are

not available for the RRPs. That is, the ring ports cannot be disabled nor can their

configuration be changed.

Trunking — RapidRing and trunking cannot use the same ports. If a ring port exists as

part of a trunk, the ring cannot be enabled. Either remove the ring port(s) from the trunk

or disable the trunk that includes the ring port(s). Otherwise, the ring cannot be

established. Once a ring is enabled, its ports cannot be added to a trunk.

Mirroring — RapidRing ports may be mirrored like any other port, but neither RRP

should be designated as the Mirror Port (see Section 4.4.3).

VLANs — The RRPs must be included in the same VLAN or in none at all.

Multicast Filtering and Static Forwarding — RRPs may be used for these functions,

but the backup RRP (of the ring master) is normally unavailable.

QoS — RRPs do support QoS.

4.4.9.3.3 Multiple RapidRings

RapidRing will also support up 100 interconnected rings (each having its own ID

number) — allowing greater flexibility of wiring and network styles. Figure 37 shows two

rings connected via two redundant network links — thus protecting against failure of a

single cable within the trunk. (However, the two rings could be connected by just one

link, if inter-ring redundancy were not required.) The two switches providing the inter-

ring connection may be either master or slave and may use any available non-RRP.

Figure 37 — Dual RapidRings

To set up the RapidRing, select System Configuration, then Configure Redundancy

(described in Section 4.4.9) then select the RapidRing

option. Also, if the two rings are

to have redundant lines between them, configure a trunk between the two switches that

connect the rings together. (See Section 4.4.2 for configuring a trunk).
