Enabling BFD for an aggregation group

This feature is available in Release 2406P03 and later versions.
BFD for Ethernet link aggregation can monitor member link status in an aggregation group. After you
enable BFD on an aggregate interface, each Selected port in the aggregation group establishes a BFD
session with its peer port. All the BFD sessions use UDP port 6784 and destination MAC address
01-00-5E-90-00-01. BFD operates differently depending on the aggregation modes.
• BFD for static aggregation—When BFD detects a link failure, BFD notifies the Ethernet link
aggregation module that the peer port is unreachable. The local port is placed in the Unselected
state. The BFD session between the local and peer ports remains, and the local port keeps sending
BFD packets. When the link is recovered, the local port receives BFD packets from the peer port,
and BFD notifies the Ethernet link aggregation module that the peer port is reachable. The local
port is placed in the Selected state again. This mechanism ensures that the local and peer ports of
a static aggregate link have the same aggregation state.
BFD for dynamic aggregation—When BFD detects a link failure, BFD notifies the Ethernet link
•
aggregation module that the peer port is unreachable. BFD clears the session and stops sending
BFD packets. When the link is recovered and the local port is placed in the Selected state again, the
local port establishes a new session with the peer port. BFD notifies the Ethernet link aggregation
module that the peer port is reachable. Because BFD provides fast failure detection, the local and
peer systems of a dynamic aggregate link can negotiate the aggregation state of their member
ports faster.
