lacp (Aggregated Ethernet)
Syntax (T, PTX, MX Series)
Hierarchy Level ( PTX, MX Series)
Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 15.1F4 for PTX Series routers.
fast-failover option introduced in Junos OS Release 12.2.
Support for logical systems introduced in Junos OS Release 14.1.
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.
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.
If you do not specify LACP as either active or passive, LACP remains passive.
You must also configure multichassis link aggregation (MC-LAG) when you configure the admin-key.
The remaining statements are explained separately. See CLI Explorer.
