4.3.9.3.1.1 RapidRing and Other Management Features
As a rule, when ring ports are enabled for RapidRing use, they should not be involved

with other management features. Specific issues are described below.
Port Parameters — If RapidRing is enabled, the “Configure Ports” options (Figure 6)

are not available for the ring ports. That is, 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. If a ring is enabled, its ports cannot be added to a trunk.
Mirroring — RapidRing ports may be mirrored like any other port, but neither of the ring

ports should be designated as a Mirror Port (see Section 4.2.1.4).
VLANs — Ring ports must be included in the same VLAN or in none at all.
Multicast Filtering and Static Forwarding — RapidRing ports may be used for these

functions, but the even-numbered ring port of the ring master is normally unavailable.
QoS — RapidRing ports do support QoS.

4.3.9.3.2 Multiple RapidRings

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

number) — allowing greater flexibility of wiring and network styles. Figure 34 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 unneeded.) The two switches providing the inter-ring

connection may be either master or slave but must use only non-ring ports for the trunk.

To setup the RapidRing via the console port settings, select

System Configuration,

then Configure RapidRing (described in Section 4.2.1.9.3.4). 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 4.2.1.3 for configuring a trunk).
