xStack® DES-3528/DES-3552 Series Layer 2 Stackable Fast Ethernet Managed Switch Web UI Reference Guide Sub-ring In topology (c), multiple rings share the same physical link. Only one of the rings uses the physical link (primary ring) while the other ring(s) will build-up virtual channels upon the physical link. Those rings, including the virtual link, will be the sub-rings of the primary ring. Each ring will have its own RPL owner and port, and every ring should belong to a different RAPS VLAN. This page is used to enable the ERPS function on the Switch. NOTE: STP and LBD should be disabled on the ring ports before enabling ERPS. ERPS cannot be enabled before the R-APS VLAN is created, and ring ports, RPL port, and RPL owner are configured. Note that these parameters cannot be changed when ERPS is enabled.
