Configuring ERP ERPv2 Configuration Overview and Guidelines

ERPv2 Configuration Overview and Guidelines
The following section details the guidelines and prerequisites for configuring ERPv2 and details on how to
configure the ERPv2 related parameters using the OmniSwitch CLI. Configuring the sample ERPv2 ring
network involves the following tasks:
1 Optional: Configure tagged ports or link aggregate ports before configuring ERP.
2 Configure an ERP ring with same ERP ring ID on all switches in the network.
3 Define same ERP Service VLAN on all switches.
4 Set the same Management Entity Group (MEG) (for example, level 2) for all switches.
5 Assign one switch to be the RPL owner. Configure the port connected to the Ring Protection Link as
an RPL port.
6 Enable the configured ERPv2 ring.
7 Assign separate VLANs as protected VLANs to the ERP ring.
8 Use the default settings for the guard timer and WTR timer values. These values can be adjusted as
necessary.
The following sub-sections provide the details on prerequisites and different configurations for switches to
set up an ERPv2 ring network using OmniSwitch CLI commands.
Major and Sub Ring Management
A shared link must be configured only on the major ring.
The following conditions must be considered for configuring an ERPv2 port for a shared link:
• Sub-rings can not be closed using a shared link.
• An SVLAN must exist before an ERP ring is created and must be unique per ring.
• A given port can only be configured on one ring.
• Each ring must have its own RPL.
• The RPL can be placed anywhere on the major ring including the shared links.
• The RPL can be placed anywhere on the sub-rings, including the sub-ring-port. Since the sub-ring is
not closed using the shared link, the RPL cannot be placed on the shared link.
Configuration Parameters
The following conditions must be considered before configuring an ERPv2 port:
• A given port can only be configured on one ring.
• The shared links are only configurable on the Master Ring.
• The Sub Rings cannot be closed using the shared links.
• Each ring must have its own RPL.
