How to Configure High Availability Clustering
Function:
Present information and configuration of Nomadix’ s High Availability
Clustering feature to allow multiple Edge Gateways to simultaneously service a
single layer 2 network segment, increasing the number of users or bandwidth
supported while providing high availability capabilities.
Pre-requisites:
-
High Availability Clustering and all other modules purchased for each gateway
-
Switch fabric on the Subscriber/LAN side of the Gateway Cluster will need to support LACP with Source MAC (Hospitality) or VLAN
(Managed WiFi) load balancing functionality. A switch that supports a short LACP timeout is preferred. -
DHCP pools that do not overlap and WAN IP addresses that do not conflict are configured on the gateways. Any thing not IP related, like port locations, must match.
-
Each Gateway is connected to a separate LAGG port on the switch connecting to the subscriber traffic
Configuration:
Navigate to Configuration -> Ethernet Ports/WAN. Set the Eth port to be used
as Subscriber to AGG mode and add it to the desired LAGG
Note: Only one port on each Nomadix unit can be setup as a CLS LAGG port
Then set the LAGG port to CLS (Cluster mode).
After configuration the port roles will be displayed in the Ethernet Ports/WAN
page with Eth port set to LAGG and the chosen LAGG set to CLS.
Next High Availability Clustering is configured. Navigate to Configuration ->
High Availability.
Note: This is a Licensed Module and you need to make sure your License
includes this feature.
If this is not listed, try retrieving the license key. Should the key not
change please check for purchase of the module. Enable the feature and enter
the Cluster ID and Cluster comm port. The ID and comm port are the same for
all gateways in the Cluster. Image is a four gateway Cluster.
By selecting the “Show cluster subscribers” checkbox on the Subscriber
Administration -> Current page, the subscriber table will show all subscribers
in the cluster. AAA State will be Cluster and gateway IP will appear in the
Cluster Node column if the entries are connected to a gateway other than the
one currently being viewed.
