2 firewalls configured with HA active/passive, And enabled preempt on both of firewalls
Everythings find, can synchronize configuration and session
firewall-A is active-firewall with priority 100
firewall-B is passive-firewall with priority 120
HA timer settings is recommended
But when I was testing for HA switch over by unplugged a interface on Active firewall (firewall-A), firewall-A moves into passive state, then active state again then passive state finally moves into "Preempt loop detected",
Actually I know that it will switchover 3 times after change firewall-A to suspend state
Is that a normal situation? Why does firewall-A still need to preempt itself as a active firewall even I did not put cable back (port still down)?
Hi, I found a new useful ref:
Seem when we choose shutdown mode, it will cause a preemt loop, solved by choose auto mode instead
but for layer2 environment should keep shutdown mode and disable preempt option
