HA Parameters
The High Availability (HA) parameters are described in the table below.
When configuration is applied to the device whose MAC is the value of the
HARemoteMAC parameter, all HA configuration is swapped between local and remote
parameters, including the IP address of the Maintenance interface, which is swapped
with the address configured for the HARemoteAddress parameter. For more
information, see
Quick-and-Easy Initial HA Configuration on page 639.
Table 60-20:HA Parameters
Parameter Description
[HAMaintenanceIFDiffServValue] Defines the DiffServ value for HA Maintenance
traffic flowing on the HA Maintenance interface.
The valid value is 0 (lowest priority or best-effort
service) to 63 (highest priority). The default is 46.
Note: For the parameter to take effect, a device
reset is required.

operational-state-delay
[HAOperationalStateDelayInSec]
Defines the duration (in seconds) to delay the
transition from HA non-operational state, which
occurs during HA synchronization between active
and redundant devices, to HA operational state.
This feature may be useful, for example, to delay
HA switchover when using switches with spanning
tree protocol (STP) that take a long time until their
ports (to which the redundant device is connected)
is ready. In such a scenario, if this feature were not
enabled (i.e., 0), after synchronization there would
be no connectivity between the redundant device's
network interface and the switch.
The valid value is 0 to 180. The default is 0.
[HALocalMAC] Specifies the MAC address of one of the two
devices in the HA system.
For more information, see Quick-and-Easy Initial
HA Configuration on page 639.
Note: When downloading an ini file from a device
that is operating in HA mode, the parameter is the
MAC address of the active device.
[HARemoteMAC] Specifies the MAC address of one of the two
devices in the HA system.
For more information, see Quick-and-Easy Initial
HA Configuration on page 639.
Note: When downloading an ini file from a device
that is operating in HA mode, the parameter is the
MAC address of the redundant device.
