HP VPN Firewall Appliances High Availability Command Reference

Parameters
value: Minimum interval for transmitting BFD control packets, in milliseconds. The value must be a
multiple of 10.
Usage guidelines
A proper interval ensures that BFD control packets are not transmitted faster than the device can deal with.
The actual interval for transmitting BFD control packets at the local device should be the greater between
the minimum interval for sending BFD control packets configured on the local interface and the minimum
interval for receiving BFD control packets on the remote device.
Examples
# Configure the minimum interval for transmitting BFD control packets on GigabitEthernet 1/1 as 500
milliseconds.
