Configuring an edge aggregate interface
When you configure an edge aggregate interface, follow these restrictions and guidelines:
•
This configuration takes effect only on the aggregate interface corresponding to a dynamic
aggregation group.
•
Link-aggregation traffic redirection does not operate correctly on an edge aggregate interface.
For more information about link-aggregation traffic redirection, see "

Enabling BFD for an aggregation group
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. BFD operates differently depending on the aggregation mode.
•
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 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 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 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.
