Figure: Advanced_Redundancy_T2
Example:
This example shows how to setup Server redundancy within an N-Ring and N-Link network.
Topology 1 shows the Network architecture without the clients.
Topology 2 is a subset of Topology 1 and shows the Redundant Servers, a Relay Agent with
attached Clients. The Relay Agent will be configured to forward broadcast request to both
servers and will define Option82 mappings to support the Clients.
Setup:
First Step: Configure N-Link to redundantly couple 2 N-Ring networks
Reference Figure: Advanced_Redundancy_T1 and the User Manual & Installation Guide for
the switch.
Ensure the Coupler and Control cables are disconnected at this point.
Get Both N-Rings working with Status OK.
Configure N-Link Slave: Ensure that the N-Link Slave is set to Auto Configure. Save
Configuration.
Configure N-Link Master: Select the Control and Coupler ports. Save the Configuration.
Connect the Control Link cable.
Connect the Coupler Link cables.
Check N-Link status by selecting the N-Link Status View page.
NOTE: There must be an N-Link aware switch on either side of the Master.
NOTE: There must be a direct link between the Master and Slave Control ports and between the
Master and Slave Partner ports. Use of media converters or other switches in these locations is
not supported.
Second Step: Configure the DHCP Servers for Redundancy
The Servers will be configured identically with Option61 Static Mappings.
