to enable BFD for an aggregation group.
Use

ip-address
undo link-aggregation bfd
Default
BFD is disabled for an aggregation group.
Views

Predefined user roles

Parameters
source ip-address
: Specifies the unicast source IP address of BFD sessions. The source IP
address cannot be 0.0.0.0.
destination
ip-address
: Specifies the unicast destination IP address of BFD sessions. The
destination IP address cannot be 0.0.0.0.
Usage guidelines
Make sure the source and destination IP addresses are reversed between the two ends of an
aggregate link. For example, if you execute
link-aggregation bfd ipv4 source 1.1.1.1
destination 2.2.2.2
at the local end, execute
link-aggregation bfd ipv4 source
2.2.2.2 destination 1.1.1.1
at the peer end. The source and destination IP addresses
cannot be the same.
The BFD parameters configured on an aggregate interface take effect on all BFD sessions
established by the member ports in its aggregation group. BFD on an aggregate link supports only
control packet mode for session establishment and maintenance. The two ends of an established
BFD session can only operate in Asynchronous mode. For more information about BFD, see
High
Availability Configuration Guide
.
As a best practice, do not configure BFD for any protocols on a BFD-enabled aggregate interface.
Make sure the number of member ports in the BFD-enabled aggregation group is less than or
identical to the number of BFD sessions supported by the device. If the aggregation group contains
more member ports than the supported sessions, some Selected ports might change to the
Unselected state.
If the number of BFD sessions differs between the two ends of an aggregate link, check their settings
for inconsistency in the maximum number of Selected ports. You must make sure the two ends have
the same setting for the maximum number of Selected ports.
Examples
# Enable BFD for Layer 2 aggregation group 1, and specify the source and destination IP addresses
as 1.1.1.1 and 2.2.2.2 for BFD sessions.
