ELEASE NOTE INFORMATION
In some cases, these identifiers could collide with either another Server
Load Balancer and Server Load Balancer Plus or with other network
devices that are taking part in the VRRP protocol.
As a result, it may be necessary to override the VRIDs used by the Server
Load Balancer and Server Load Balancer Plus. To override these values,
you must be at the
Logical View and complete the following:
1 Select Server Load Balancing > Redundancy Setting from the Navigation
tree. The Redundancy Settings page is displayed.
2 Enter an identifier with a value between 1 and 255.
See the Server Load Balancer and Server Load Balancer Plus User Guide
for information.
Restricted
Management
Topology
In a redundant configuration, the Server Load Balancer and Server Load
Balancer Plus automatically detect and learn about the peer device (a
Server Load Balancer or Server Load Balancer Plus) that it is associated
with.
To properly handle management traffic associated with the peer device,
the Server Load Balancer and Server Load Balancer Plus dynamically
create certain forwarding filters. As a result, a client directly connected to
a Server Load Balancer or Server Load Balancer Plus are not be able to
manage the peer Server Load Balancer and Server Load Balancer Plus
through the device that it is attached to.
To ensure that management traffic to the Server Load Balancer or Server
Load Balancer Plus works properly in a redundant configuration, the
client station should be attached via a L2 device that connects both
Server Load Balancer and Server Load Balancer Plus’s together.
Changing
Redundancy Types
The Server Load Balancer and Server Load Balancer Plus must be reset to
a factory configuration when changing the redundancy types selected.
For example, if the Server Load Balancer or Server Load Balancer Plus has
been configured for Active-Passive operation and you want to change to
and Active-Active configuration, the Server Load Balancer or Server Load
Balancer Plus must be reset to factory defaults and the setup wizards
must be re-run in order to select the Active-Active mode.
