The interval can be fast (every second) or slow (every 30 seconds). You can configure
different periodic rates on active and passive interfaces. When you configure the
active and passive interfaces at different rates, the transmitter honors the receiver s
rate.
NOTE: Source address filtering does not work when LACP is enabled. For more
information about source address filtering, see "Enabling Ethernet MAC Address
Filtering" on page 610.
Percentage policers are not supported on aggregated Ethernet interfaces with the
CCC protocol family configured. For more information about percentage policers,
see the JUNOS Policy Framework Configuration Guide.
Generally, LACP is supported on all untagged aggregated Ethernet interfaces. For
more information, see "Configuring Untagged Aggregated Ethernet Interfaces" on
page 655.
For M Series Multiservice Edge Routers with enhanced Flexible PIC Concentrators
(FPCs) and T Series routers, LACP over VLAN-tagged aggregated Ethernet interfaces
is supported. For 8-port, 12-port, and 48-port Fast Ethernet PICs, LACP over
VLAN-tagged interfaces is not supported.
Configuring LACP Link Protection
NOTE: When using LACP link protection, you can configure only two member links
to an aggregated Ethernet interface: one active and one standby.
To force active and standby links within an aggregated Ethernet, you can configure
LACP link protection and system priority at the aggregated Ethernet interface level
using the
level results in only the configured interfaces using the defined configuration. LACP
interface configuration also enables you to override global (chassis) LACP settings.
LACP link protection also uses port priority. You can configure port priority at the
Ethernet interface
If you choose not to configure port priority, LACP link protection uses the default
value for port priority (127).
NOTE: LACP link protection supports per-unit scheduling configuration on aggregated
Ethernet interfaces.
