Hierarchy Level [edit interfaces aex aggregated-ether-options]
Release Information Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 9.0 for EX Series switches.
fast-failover option introduced in Junos OS Release 12.2.
Description Configure the Link Aggregation Control Protocol (LACP) for aggregated Ethernet interfaces
only.
When you configure the accept-data statement at the [edit interfaces aeX
aggregated-ether-options lacp] hierarchy level, the router processes packets received on
a member link irrespective of the LACP state if the aggregated Ethernet bundle is up.
NOTE: When you configure the accept-data statement at the [edit interfaces
aeX aggregated-ether-options lacp] hierarchy level, this behavior occurs:
• By default, the accept-data statement is not configured when LACP is
enabled.
• You can configure the accept-data statement to improve convergence and
reduce the number of dropped packets when member links in the bundle
are enabled or disabled.
• When LACP is down and a member link receives packets, the router or
switch does not process packets as defined in the IEEE 802.1ax standard.
According to this standard, the packets should be dropped, but they are
processed instead because the accept-data statement is configured.
Default If you do not specify LACP as either active or passive, LACP remains passive.
Options active—Initiate transmission of LACP packets.
admin-key number—Specify an administrative key for the router or switch.
