Description
Configure the Link Aggregation Control Protocol (LACP) parameters for interfaces. The remaining statement is explained separately.
For EX Series, 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-datastatement is not configured when LACP is enabled.You can configure the
accept-datastatement 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-datastatement is configured.
The force-up statement is not supported on QFX10002 switches.
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. Note:
You must also configure multichassis link aggregation
(MC-LAG) when you configure the |
| fast-failover | Specify to override the IEEE 802.3ad standard and allow the standby link to receive traffic. Overriding the default behavior facilitates subsecond failover. |
| passive | Respond to LACP packets. |
The remaining statements are explained separately. See CLI Explorer.
