CHAPTER 32 HA Configuration
Mediant 4000 SBC | User's Manual
Step 1: Configure the First Device
The first stage is to configure the first device for HA.
During this stage, make sure that the second device is powered off or disconnected
from the network.
➢
To configure the first device for HA:
1. Configure the network interfaces, including the default OAMP interface:
a. Connect your PC to the device using a local, direct physical cable connection and then
access the Web interface using the default OAMP network address. For more information
on initial access, see
Assigning the OAMP IP Address .
b. Open the IP Interfaces table (see Configuring IP Network Interfaces ).
c. Change the default OAMP network settings to suit your networking scheme.
d. Configure the Control and Media network interfaces, as required.
e. Add the HA Maintenance interface (i.e., the MAINTENANCE Application Type).
Make sure that the Maintenance interface uses an Ethernet Device and Ethernet Group
that is
not used by any other IP network interface. The Ethernet Group is associated
with the Ethernet Device, which is assigned to the interface.
The IP Interfaces table below shows an example where the Maintenance interface is configured
with Ethernet Device "vlan 2" (which is associated with Ethernet Group "GROUP_2"), while the
other interface is assigned "vlan 1" (associated with Ethernet Group "GROUP_1"):
2. If the connection is through a switch, the packets of both interfaces should generally be
untagged. To do this, open the Ethernet Devices table (see
Configuring Underlying Ethernet
Devices ), and then configure the 'Tagging' parameter to Untagged for the Ethernet Device
assigned to the Maintenance interface. The figure below shows an example (highlighted) where
VLAN 2 is configured as the Native (untagged) VLAN ID of the Ethernet Group "GROUP_2":
3. Set the Ethernet port Tx / Rx mode of the Ethernet Group used by the Maintenance interface
(see
Configuring Ethernet Port Groups ). The port mode depends on the type of Maintenance
connection between the devices, as described in Network Topology Types and Rx/Tx Ethernet
Port Group Settings .
4. Configure HA parameters:
a. Open the HA Settings page ( Setup menu > IP Network tab > Core Entities folder > HA
Settings ):
