6.
Enable ERPS ( Configure Global ): Before enabling a ring as described in
the next step, first globally enable ERPS on the switch. If ERPS has not
yet been enabled or has been disabled, no ERPS rings will work.
7.
Enable an ERPS ring ( Configure Domain – Configure Details ): Before an
ERPS ring can work, it must be enabled. When configuration is
completed and the ring enabled, R-APS messages will start flowing in
the control VLAN, and normal traffic will begin to flow in the data
VLANs. A ring can be stopped by disabling the Admin Status on any
node.
8.
Display ERPS status information ( Configure Domain – Show ): Display
ERPS status information for all configured rings.
Configuration Limitations for ERPS
The following configuration limitations apply to ERPS:
◆
One switch supports up to six ERPS rings – each ring must have one
Control VLAN, and at most 255 Data VLANs.
◆
Ring ports can not be a member of a trunk, nor an LACP-enabled port.
◆
Dynamic VLANs are not supported as protected data ports.
◆
Exclusive use of STP or ERPS on any port.
◆
The switch takes about 350 ms to detect link-up on 1000Base-T copper
ports, so the convergence time on this port type is more than 50 ms.
◆
One VLAN must be added to an ERPS domain as the CVLAN. This can be
designated as any VLAN, other than the management VLAN. The
CVLAN should only contain ring ports, and must not be configured with
an IP address.
