JUNOS 10.1 Network Interfaces Configuration Guide
LACP exchanges are made between actors and partners. An actor is the local interface
in an LACP exchange. A partner is the remote interface in an LACP exchange.
LACP is defined in IEEE 802.3ad, Aggregation of Multiple Link Segments.
LACP was designed to achieve the following:
The JUNOS implementation of LACP provides link monitoring but not automatic
addition and deletion of links.
The LACP mode can be active or passive. If the actor and partner are both in passive
mode, they do not exchange LACP packets, which results in the aggregated Ethernet
links not coming up. If either the actor or partner is active, they do exchange LACP
packets. By default, LACP is in passive mode on aggregated Ethernet interfaces. To
initiate transmission of LACP packets and response to LACP packets, you must enable
LACP active mode.
To enable LACP active mode, include the
interface-name aggregated-ether-options]
To restore the default behavior, include the
interface-name aggregated-ether-options]
For more information, see the following sections:
Configuring the LACP Interval
By default, the actor and partner send LACP packets every second. You can configure
the interval at which the interfaces send LACP packets by including the
statement at the
level:
650
Configuring Aggregated Ethernet LACP
Automatic addition and deletion of individual links to the aggregate bundle
without user intervention
Link monitoring to check whether both ends of the bundle are connected to the
correct group
