HA Maintenance

This section describes HA maintenance procedures.
33.1

Maintenance of Redundant Device

The only interface that is operational on the redundant device is the Maintenance interface.
The following protocols can be used for maintenance purposes for this interface:

Syslog: To receive Syslog messages from the redundant device, make sure that you
have configured a valid VLAN and routing rule from the Maintenance network to the
Syslog server.

Telnet: A Telnet server is always available on the redundant device (even if disabled
by configuration).
The active device runs the above maintenance protocols on its' OAMP interface.
33.2

Replacing a Failed Device

If you need to replace a faulty device, the new device must be configured exactly as the
second device, as described in ''Configuring the HA Devices'' on page 548.
33.3

Forcing a Switchover

If required, you can force a switchover between active and redundant devices. For more
information, see ''High Availability Maintenance'' on page 565.
