Failover Constraints
Before you begin configuring failover, you must do the following:
1. Ensure that the VLAN configuration on both EQ/OS 10 Equalizer is
exactly
the same.
2. In some cases there may appear to be an issue where the Primary and Backup Equalizers
are in a conflict over Primary. Any switch, such as one from Cisco or Dell, that comes with
Spanning Tree Protocol enabled by default can cause a communication problem in a failover
configuration. This problem occurs at boot up because the switch disables its ports for
roughly 30 seconds to listen to BPDU (Bridge Protocol Data Unit) traffic. The 30 second
pause causes both Equalizers to attempt to become the primary unit, and the default backup
continually reboots. To repair this condition, either disable Spanning Tree Protocol or enable
PortFast for the ports connected with the Equalizers. This enables the ports to act as normal
hubs and accept all traffic immediately.
3. When configuring VLAN subnets, the following must be true:
l
the
heartbeat
flag must be enabled on
at least one
VLAN
l
the
command
flag must be enabled on
exactly one
VLAN
l
the
Failover IP
(
virt_addr
in the CLI) parameter must be set on all VLAN subnets
that have the
heartbeat
or
command
flags enabled
