In Bonding Load Sharing mode:
Note - Bonding Load Sharing mode requires SecureXL to be enabled on each Cluster Member.
In Bonding Load Sharing mode, when the Security Gateway is part of a cluster, bond internal failover can occur in one of these cases:
Either of these failures will induce a failover within the interface bond, or between Cluster Members, depending on the circumstances.
When a failure is detected, a log is recorded. You can see it in SmartConsole > Logs & Monitor > Logs.
Follow the instructions in the R80.20 Gaia Administration Guide - Chapter Network Management - Section Network Interfaces - Section Bond Interfaces (Link Aggregation).
Note - The Critical Required Interfaces feature is supported for ClusterXL only.
A bond in Load Sharing mode is considered to be down when fewer than a critical minimal number of slave interfaces remain up. When not explicitly defined, the critical minimal number of slave interfaces, which must remain up, in a bond of n interfaces is n-1. Failure of an additional slave interface (when n-2 slave interfaces remain up) will cause the entire bond interface to be considered down, even if the bond contains more than two slave interfaces.
If a smaller number of slave interfaces will be able to handle the expected traffic, you can increase redundancy by explicitly defining the critical minimal number of slave interfaces. Divide your maximal expected traffic speed by the speed of your slave interfaces and round up to a whole number to determine an appropriate number of critical slave interfaces.
To define the critical number of slave interfaces explicitly, create and edit the following file:
$FWDIR/conf/cpha_bond_ls_config.conf
Each line of the file should be written in the following syntax:
<Name_of_Bond> <critical_minimal number_of_slave>
For example, if bond0
has 7 slave interfaces, and bond1
has 6 slave interfaces, file contents could be:
bond0 5
bond1 3
In this example:
bond0
would be considered down when 3 of its slave interfaces have failed.bond1
would be considered down when 4 of its slave interfaces have failed.Verify that the bond interface is UP, by displaying the bond information.
show cluster members interfaces all
cphaprob -am if
Make sure that the bond status is reported as UP
.
show cluster bond {all | name
<Name of Bond>}
cphaprob show_bond
<Name of Bond>
Check that the bond is correctly configured.
