Create an IP-Trunk interface.
Configure single-hop BFD for an IP-Trunk link.
Peer IP address for a BFD session, which is the IP address of the peer IP-Trunk interface
Local interface sending and receiving BFD control packets
Local and remote discriminators of a BFD session
NOTE
Default values of the minimum sending interval, minimum receiving interval, and local detection multiplier
for BFD control packets are used.
NOTE
By default, the lower threshold of IP-Trunk member links in the Up state is 1. It is configurable based on
networking environments.
