## Symptoms

- Quantum Edge Gateways Cluster running on VeloCould failover randomly.

## Cause

VeloCloud uses SNMP method of querying The Check Point Security Gateways for liveliness. SNMP is a user space application, so when the firewall (which sits in the kernel space) is overloaded, SNMP does not get a chance to respond, and the Edge Gateways Cluster failover.

## Solution

This problem was fixed. The fix is included starting from:

* [Quantum Edge R80.20.60 for VeloCloud](https://support.checkpoint.com/results/download/127299)

After installing the new version, add these parameters to the *fwkern.conf* file. For more information refer to [sk26202 - Changing the kernel global parameters on Check Point Security Gateways](https://support.checkpoint.com/results/sk/sk26202).

On each Cluster member:

1. Backup the file *$FWDIR/boot/modules/fwkern.conf*.

2. Edit the file and add these lines:

   `cloud_balancer_port=161`  
   `cloud_balancer_ip1=0x01000000`  
   `cloud_balancer_ip2=0xfffffffe`  
   `cloud_balancer_use_ip_ranges=1`
3. Save the *$FWDIR/boot/modules/fwkern.conf* file and reboot the appliance.
