Configuring Bond High Availability in VRRP Cluster

Note - This section does not apply to Scalable Platforms (ElasticXL, Maestro, and Chassis).

The R80.20 version introduced an improved Active/Backup Bond mechanism (Enhanced Bond) when working in ClusterXL.

If you work with ClusterXL, the Enhanced Bond feature is enabled by default, and no additional configuration is required.

If you change your cluster configuration from ClusterXL to VRRP (MCVR & VRRP), or configure the VRRP (MCVR & VRRP) cluster from scratch, the Enhanced Bond feature is disabled by default.

If you change your cluster configuration from VRRP to ClusterXL, you must manually enable the Enhanced Bond feature.

To enable the Enhanced Bond feature in VRRP Cluster, set the value of the kernel parameter fwha_bond_enhanced_enable to 1 on each VRRP Cluster Member. You can set the value of the kernel parameter temporarily, or permanently.

Important - This change does not survive reboot.

Step

Instructions

1

Connect to the command line on each VRRP Cluster Member.

2

Log in to the Expert mode.

3

Set the value of the kernel parameter fwha_bond_enhanced_enable to 1:

fw ctl set int fwha_bond_enhanced_enable 1

4

Make sure the value of the kernel parameter fwha_bond_enhanced_enable was set to 1:

fw ctl get int fwha_bond_enhanced_enable

Step

Instructions

1

Connect to the command line on each Cluster Member.

2

Log in to the Expert mode.

3

Back up the current $FWDIR/boot/modules/fwkern.conf file:

cp -v $FWDIR/boot/modules/fwkern.conf{,_BKP}

4

Edit the current $FWDIR/boot/modules/fwkern.conf file:

vi $FWDIR/boot/modules/fwkern.conf

5

Add this line to the file (spaces and comments are not allowed):

fwha_bond_enhanced_enable=1

6

Save the changes in the file and exit the editor.

7

Reboot the Cluster Member.

8

Make sure the value of the kernel parameter fwha_bond_enhanced_enable was set to 1:

fw ctl get int fwha_bond_enhanced_enable

Important - If you change your cluster configuration from VRRP to ClusterXL, you must remove the kernel parameter configuration from each Cluster Member.
