For aggregated Ethernet interfaces on J-EX Series switches, you can configure the Link
Aggregation Control Protocol (LACP). LACP is one method of bundling several physical
interfaces to form one logical interface. You can configure aggregated Ethernet with or
without LACP enabled.
Before you configure LACP, be sure you have:
Configured the aggregated Ethernet bundles—also known as link aggregation groups
(LAGs). See "Configuring Aggregated Ethernet Interfaces (CLI Procedure)" on page 922
When LACP is enabled, the local and remote sides of the aggregated Ethernet links
exchange protocol data units (PDUs), containing information about the state of the link.
You can configure Ethernet links to actively transmit PDUs, or you can configure the links
to passively transmit them, sending out LACP PDUs only when they receive them from
another link. One side of the link must be configured as
NOTE: Do not add LACP to a LAG if the remote end of the LAG link is a security
device, unless the security device supports LACP. Security devices often do
not support LACP because they require a deterministic configuration.
To configure LACP:
Enable one side of the aggregated Ethernet link as active:
1.
[edit interfaces]
user@switch# set aex aggregated-ether-options lacp active
Specify the interval at which the interfaces send LACP packets:
2.
[edit interfaces]
user@switch# set aex aggregated-ether-options lacp periodic fast
