Setting Up a Failover Configuration
Equalizer Installation and Administration Guide 95
• Failover IP (must be provided on all VLANs for failover to work)
• GUI access
• SSH access
Do the following on both failover systems:
a. Click on the Equalizer system name in the left frame and then open the
Networking > VLAN Configuration
tab in the right frame.
b. Use the Modify button in the
Actions
column of the table to examine each VLAN.
c. See the table on page 67 for a description of the
Modify VLAN
dialog parameters.
2. Check the sequence number on both systems. To do this click the
Help
icon on the top bar of the Administrative
Interface and select
About
from the menu. Point at the
System Information
box to expand it and show the
sequence number. The configuration file with the highest sequence number will be transferred to the other when
failover is established. See the section “Updating the Configuration File Sequence Number” on page 312 if you
need to edit the sequence number to preserve the configuration you require.
3. Log into the Equalizer Administration Interface on the failover peer that will assume the
preferred primary
role. Use a login that has add/del access on global parameters to initially define the configuration, or write
access on global parameters to update an existing failover configuration. (Configuring the preferred primary
Equalizer first ensures that it assumes the primary role.)
4. Select
Mode: Standalone
(or the Failover Peer Name ) at the top of the left frame object tree, and then open the
Synchronization
tab in the right frame to set failover configuration transfer options:
If you make any changes, click
commit
.
5. Open the
Timing
tab to update the default failover timer settings, if necessary:
dont transfer
By default, changes committed to the configuration on the primary
system are transmitted to the backup system when the next heartbeat
occurs. Enabling this flag tells Equalizer not to transfer configuration
changes to the peer Equalizer. Used when the peer Equalizers are
different hardware models or are running different software versions.
This is normally necessary only during the process of upgrading a
failover pair to a new software version, and you want to upgrade the
peers at different times to maintain service. After both peers are
upgraded to the new release, you can disable this flag on both peers.
Transfer envoy
configuration When enabled (the default), the current Envoy configuration is included
when a configuration transfer to the failover peer occurs.
Transfer Certificates
When enabled (the default), the all HTTPS cluster and client security
certificates stored on Equalizer are included when a configuration
transfer to the failover peer occurs.
Transfer DNS
Configuration
When enabled (the default), the current DNS configuration is included
when a configuration transfer to the failover peer occurs.
Transfer Syslog
Configuration
When enabled (the default), the current remote syslog configuration is
included when a configuration transfer to the failover peer occurs.
Use SSL Only
By default, configuration transfers between failover peers are performed
using non-secure connections. If this option is enabled, SSL is used for
all configuration transfers.
receive timeout
Time in seconds (default: 0.6) to wait for a heartbeat response from
peer before timing out.
