to have a LAG link configured and 802.3ad enabled for each redundant Ethernet
interface LAG on both nodes so that the aggregate links will be recognized.
Standalone link aggregation group interfaces (
ae
) are supported on clustered
devices but cannot be added to redundant Ethernet interfaces. Likewise any
child interface of an existing LAG cannot be added to a redundant Ethernet
interface and vice versa. The maximum number of total combined standalone
aggregate interfaces (
ae
) and redundant Ethernet interfaces (
reth
) per cluster is
128.
Redundant Ethernet interface configuration also includes a minimum-links setting
that allows you to set a minimum number of physical child links in a redundant
Ethernet interface LAG that must be working on the primary node for the interface
to be up. The default minimum-links value is 1. When the number of physical
links on the primary node in a redundant Ethernet interface falls below the
minimum-links value, the interface will be down even if some links are still
working.
Note that management, control, and fabric interfaces do not support standalone
LAGs or redundant Ethernet interface LAGs in JUNOS Release 10.1.

Redundancy group IP address monitoring through a secondary interface
—This
feature is supported on SRX3400, SRX3600, SRX5600 and SRX5800 devices.
In JUNOS Release 10.1, redundancy group IP address monitoring through a
redundant Ethernet (reth) interface has been extended to include monitoring of
addresses on secondary links as well as on primary links. Redundancy group
failover can thus be tied to the health of both any IP addresses that are currently
important to traffic reliability and to any IP addresses that will become important
to traffic reliability in the event of a failover.
Monitoring can be accomplished only if the IP address is reachable on a redundant
Ethernet interface, and IP addresses cannot be monitored over a tunnel. IP
address monitoring is not supported on redundant Ethernet interface LAGs or
the child interfaces bound to a redundant Ethernet interface LAG. The feature
also cannot be used on a cluster running in transparent mode. The maximum
number of total monitoring IPs that can be configured per cluster remains 32
for SRX3400 and SRX3600 devices, and 64 for SRX5600 and SRX5800 devices.
