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 dynamic trunk.
• 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.
ERPS Global Configuration
Use the Administration > ERPS (Configure Global) page to globally enable or disable ERPS on the
switch.
