Alcatel-Lucent 7710 SR OS Interface Configuration Manual page 297

Description
This command specifies the timer, in tenths of seconds, which controls the delay between detecting
that a LAG is down (all active ports are down) and reporting it to the higher levels.
A non-zero value can be configured, for example, when active/standby signalling is used in a 1:1
fashion to avoid informing higher levels during the small time interval between detecting that the
LAG is down and the time needed to activate the standby link.
Default
0
Parameters
down hold-down-time — Specifies the hold-time for event reporting
lacp
Syntax lacp [mode] [administrative-key admin-key]
no lacp
Context config>lag
Description
This command specifies the LACP mode for aggregated Ethernet interfaces only. This command
enables the LACP protocol. Per the IEEE 802.3ad standard, the Link Aggregation Control Protocol
(LACP) provides a standardized means for exchanging information between Partner Systems on a
link to allow their Link Aggregation Control instances to reach agreement on the identity of the Link
Aggregation Group to which the link belongs, move the link to that Link Aggregation Group, and
enable its transmission and reception functions in an orderly manner. LACP can be enabled on a
maximum of 256 ports.
Default
no lacp
Parameters
mode — Specifies the mode in which LACP will operate.
administrative-key admin-key — Specifies an administrative key value to identify the channel group
lacp-xmit-interval
Syntax lacp-xmit-interval {slow | fast}
Context config>lag
Description This command sepcifies the interval signaled to the peer and tells the peer at which rate it should
transmit.
Default
fast
