5. Configure the ERPS Control VLAN (CVLAN): Use the control-vlan
command to create the VLAN 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: Before enabling a ring as described in the next step, first
use the erps command to globally enable ERPS on the switch. If ERPS
has not yet been enabled or has been disabled with the no erps
command, no ERPS rings will work.
7. Enable an ERPS ring: Before an ERPS ring can work, it must be enabled
using the enable command. 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. To stop a ring, it
can be disabled on any node using the no enable command.
8. Display ERPS status information: Use the show erps command to
display general ERPS status information or detailed ERPS status
information for a specific ring.
erps This command enables ERPS on the switch. Use the no form to disable this
