Default value of 'forward_delay' parameter in VSX Gateway Technical Level
Symptoms
  • When adding Virtual Switch (using an interface that was never used, i.e., it is not shown in 'fw ctl iflist' output), the Standby member changes its state to 'Down' for some time. Output of 'cphaprob -a if' shows that the interface that is used by the Virtual Switch is in 'Down' state during that time.

  • After fail-over or fail-back, the traffic does not pass through Bridge interface that is used by the Virtual Switch on new Active member for some time.
Cause

Default value of 'forward_delay' parameter for Bridge interface is set to some integer value.
