Enables member-link based BFD and configures the BFD link aggregation (linkagg) session values. Member-link based BFD detects individual link failures faster than LACP and reduces the overall session/traffic down period as a result of single member link failure.

Entering the above command sequence results in the following prompt:
bfd linkagg-peer linkagg_group_id local-endpt-addr local_endpt_ipaddress remote-endpt-addr remote_endpt_ipaddress interval tx_interval min_rx rx_interval multiplier multiplier_value [ slot slot_number ] no bfd linkagg-peer linkagg_group_id [ slot slot_number ]
Disables this member-link BFD configuration.
Specifies the LAG number as an integer from 1 through 255.
Specifies the source address of the multihop BFD session in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal format.
Specifies the remote address of the Multihop BFD session in IPv4 dotted-decimal or IPv6 colon-separated-hexadecimal format.
Specifies the transmit interval of control packets in milliseconds as an integer from 50 through 10000.
Specifies the minimum receive interval for control packets in milliseconds as an integer from 50 through 10000.
Specifies the value used to compute hold-down time as an integer from 3 through 50.
For a redundant active-standbylinkagg configuration, this option specifies the card for which this configuration is intended.
Use this command to enables member-link based BFD and configures the BFD link aggregation session values (RFC 7130). Member-link based BFD detects individual link failures faster than LACP and reduces the overall session traffic down period as a result of single member link failure.
This command configures BFD interactions with the linkagg task. Once a session is configured, BFD creates per member link BFD sessions and starts sending packets on each of the linkagg member links. If a member link BFD session fails, StarOS notifies failures to the linkagg task.
If you define a linkagg-peer using a slot number, you may configure a linkagg-peer for the redundant slot which must also specify a slot. Likewise, if you configure a linkagg-peer without a slot, you must delete it before configuring a peer with a slot specified.
Only one IPv4 or IPv6 BFD session-based configuration is allowed per link-agg interface for compliance with RFC 7130.
