formats, we do not want configuration transfers to be performed between the peers. This means that
changes made to the Equalizer configuration will need to be performed on both peers.
As stated above, the
Peer Signature
is not used when one peer is running 8.5 and one is running 8.6. If the peer
running Version 8.5 is subsequently upgraded to Version 8.6, the newly upgraded system will remain in the
‘
initializing
’ failover mode until you add each peer’s signature to the other unit, as follows:
1. Log into the Equalizer Administration Interface on the newly upgraded Equalizer.
2. Select the Failover Peer Name at the top of the left frame.
3. In the
This Equalizer
field, copy the contents of the
Signature
text box using the mouse or
keyboard.
4. Log into the Equalizer Administration Interface on the current primary Equalizer.
5. Select the Failover Peer Name at the top of the left frame.
6. In the
Peer Equalizer
field, paste the
Signature
you obtained in the previous step into the
Signature
text box. Click
commit
.
7. In the
This Equalizer
field, copy the contents of the Signature text box using the mouse or
keyboard.
8. Go back to the newly upgraded Equalizer. In the
Peer Equalizer
field, paste the
Signature
you
obtained in the previous step into the
Signature
text box. Click

Using a GX and an ‘si’ in Failover with Version 8.6
Note the following when configuring a GX and an ‘si’ Equalizer (both running Version 8.6) in a failover pair:
• The GX Equalizer must have exactly the same VLAN configuration as the ‘si’ system. Note that ‘si’
systems support up to two untagged (port-based) VLANs.
• Both Equalizers must be configured using the
Failover
tabs as described in “Enabling Failover Using the
Failover Tabs” on page 94. The Failover Wizard cannot be used.
Setting Up or Modifying Failover Using the Failover Wizard
The Failover Wizard allows you to setup failover on one machine and transfer the configuration over to the other.
The only information that both machines need to know are each other’s peer fingerprints. The wizard simplifies the
failover setup process, so that most information is entered on one Equalizer and then transferred to the other.
The Wizard can only be used when configuring failover between two GX model Equalizers running Version 8.6.
Failover between a GX and an ‘si’ Equalizer requires that you use the Failover tabs, as desribed in the section
“Using a GX and an ‘si’ in Failover with Version 8.6” on page 92.
Launch the Failover Wizard from the preferred primary Equalizer. Before the Failover Wizard on the preferred
primary can communicate with the other Equalizer and establish failover, you need to ensure that the VLAN
configuration on both systems is the same, and copy the failover IP of the preferred primary to the preferred backup.
Follow the procedure below:
1. Ensure that Failover IPs are assigned on all VLANs and that the VLAN configuration on both systems is the
same with respect to:
• the number of VLANs configured
• the following parameters of each VLAN:
•
VID (VLAN ID)
• VLAN netmask
• Failover IP
• Failover netmask
