HA Node Connections
You can begin software configuration for your HA node after you have:
- Completed the steps for physical set-up and connection.
- Noted the target name of the Oracle Communications Session Border Controllers that make up the HA node.
- Configured the virtual MAC addresses that you need, according to the type of physical interface cards installed on your Oracle Communications Session Border Controller.
HA Node Connection Configuration
If you are using HA, you need to set the phy-interface configuration parameters described in this section to establish successful connections. These parameters are for rear and media interfaces.
To access the phy-interface menu in the ACLI:
Rear Interfaces
You can use port 1 (wancom1) or port 2 (wancom2) as interfaces to support HA. Do not use port 0 (wancom 0) as that port is reserved for carrying management traffic.
Make sure that the physical connections you have made on the rear panel of your Oracle Communications Session Border Controllers correspond to the configurations you enter for phy-interfaces. You can connect Oracle Communications Session Border Controllers through multiple rear interfaces. For multiple rear interface connectivity, cable both port 1 and port 2 (wancom1 and wancom2) on one Oracle Communications Session Border Controller to port1 and port 2 on the other Oracle Communications Session Border Controller in the HA node.
The Oracle Communications Session Border Controller’s HA function depends heavily on health scores to determine the active and standby roles in an HA node. You can set the amount that will be subtracted from a Oracle Communications Session Border Controller’s health score in the event that a management interface fails for any reason. For example, a connection might become invalid or a cable might be removed inadvertently.
The following example shows how a configured phy-interface will appear in the ACLI for an HA node:
phy-interface
name wancom1
operation-type Control
port 1
slot 0
virtual-mac
wancom-health-score 20
To establish rear interfaces for use in an HA node using the ACLI:
Media Interface Virtual MAC Addresses
To configure HA for the media interfaces in an HA node, you must set one or more virtual MAC addresses, according to the type of physical layer cards you have installed on your Oracle Communications Session Border Controller.
To set a virtual MAC address using the ACLI:
HA Node Parameters
To establish a pair of Oracle Communications Session Border Controllers as an HA node, you need to configure basic parameters that govern how the Oracle Communications Session Border Controllers:
- Transition on switchover
- Share media and call state information
- Checkpoint configuration data
The following example shows what an HA configuration might look like in the ACLI.
redundancy-config
state enabled
log-level WARNING
health-threshold 75
emergency-threshold 50
port 9090
advertisement-time 500
percent-drift 210
initial-time 1250
becoming-standby-time 45000
becoming-active-time 100
You need to configure the two Oracle Communications Session Border Controllers to be HA node peers. To enable configuration checkpointing, you must to configure two peers in the ACLI, one for the primary and one for the secondary Oracle Communications Session Border Controller. The HA node peers configuration also allows you to configure destinations for where to send health and state information. Unless you create Oracle Communications Session Border Controller peers and destinations configurations, HA will not work properly.
The following example shows what an HA configuration might look like in the ACLI.
peer
name netnetsd1
state enabled
type Primary
destination
address 169.254.1.1:9090
network-interface wancom1:0
peer
name netnetsd2
state enabled
type Secondary
destination
address 169.254.1.2:9090
network-interface wancom1:0
