Ethernet Ring Protection Switching
– 487 –
Hold-off timer to filter out intermittent link faults, and the WTR timer to verify
that the ring has stabilized before blocking the RPL after recovery from a signal
failure.
5. Configure the ERPS control VLAN (Configure Domain – Configure Details):
Specify the control VLAN (CVLAN) used to pass R-APS ring maintenance
commands. The CVLAN must NOT be configured with an IP address. In addition,
only ring ports may be added to the CVLAN (prior to configuring the VLAN as a
CVLAN). No other ports can be members of this VLAN (once set as a CVLAN).
Also, the ring ports of the CVLAN must be tagged. Failure to observe these
restrictions can result in a loop in the network.
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:
◆ The switch supports up to six ERPS rings – each ring must have one Control
VLAN.
◆ 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.
◆ CFM detects a link failure and non-failure by using a timer of one second, so the
convergence time in this case 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.
