Priorities of Heartbeat Device
Enable or disable HA heartbeat communication and set the heartbeat priority for each
interface in the cluster.
By default HA heartbeat communication is set for two interfaces. You can disable HA
heartbeat communication for either of these interfaces or enable HA heartbeat for
other interfaces. In most cases you can maintain the default heartbeat device
configuration as long as you can connect the heartbeat device interfaces together.
To enable HA heartbeat communication for an interface, enter a priority for the
interface. To disable HA heartbeat communication for an interface, delete the priority
for the interface.
The HA heartbeat priority range is 0 to 512. The interface with the highest priority
handles all HA heartbeat traffic. If this interface fails or becomes disconnected, the
interface with the next highest priority handles all HA heartbeat traffic.
The cluster units use the ethernet interfaces configured with HA heartbeat priorities for
HA heartbeat communication. The HA heartbeat communicates cluster session
information, synchronizes the cluster configuration, synchronizes the cluster routing
table, and reports individual cluster member status. The HA heartbeat constantly
communicates HA status information to make sure that the cluster is operating
properly.
You can enable heartbeat communications for physical interfaces, but not for VLAN
subinterfaces.
None
No load balancing. Select None when the cluster interfaces are connected
to load balancing switches.
Hub
Load balancing if the cluster interfaces are connected to a hub. Traffic is
distributed to cluster units based on the Source IP and Destination IP of the
packet.
Least-
Connection
Least connection load balancing. If the cluster units are connected using
switches, select Least Connection to distribute network traffic to the cluster
unit currently processing the fewest connections.
Round-Robin
Round robin load balancing. If the cluster units are connected using
switches, select Round-Robin to distribute network traffic to the next
available cluster unit.
Weighted
Round-Robin
Weighted round robin load balancing. Similar to round robin, but weighted
values are assigned to each of the units in a cluster based on their capacity
and on how many connections they are currently processing. For example,
the primary unit should have a lower weighted value because it handles
scheduling and forwards traffic. Weighted round robin distributes traffic more
evenly because units that are not processing traffic will be more likely to
receive new connections than units that are very busy.
Random
Random load balancing. If the cluster units are connected using switches,
select Random to randomly distribute traffic to cluster units.
IP
Load balancing according to IP address. If the cluster units are connected
using switches, select IP to distribute traffic to units in a cluster based on the
Source IP and Destination IP of the packet.
IP Port
Load balancing according to IP address and port. If the cluster units are
connected using switches, select IP Port to distribute traffic to units in a
cluster based on the source IP, source port, destination IP, and destination
port of the packet.
