Statement introduced in Junos OS Release 13.2X51-D20 for EX Series switches and QFX
Series devices.
Enable local link bias for all links in the aggregated Ethernet interface.
Local link bias conserves bandwidth on Virtual Chassis ports (VCPs) by using local links
to forward unicast traffic exiting a Virtual Chassis or Virtual Chassis Fabric (VCF) that
has a Link Aggregation group (LAG) bundle composed of member links on different
member switches in the same Virtual Chassis or VCF. A local link is a member link in the
LAG bundle that is on the member switch that received the traffic.
You should enable local link bias if you want to conserve VCP bandwidth by always
forwarding egress unicast traffic on a LAG bundle out of a local link. You should not
enable local link bias if you want egress traffic load-balanced as it exits the Virtual Chassis
or VCF.
