Configuring Local Link Bias (CLI Procedure)
Local link bias is used to conserve 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. Because traffic is received and forwarded on the same member switch when local link bias is enabled, no VCP bandwidth is consumed by traffic traversing the VCPs to exit the Virtual Chassis or VCF on a different member link in the LAG bundle.
You should enable local link bias if you want to conserve VCP bandwidth by always forwarding egress unicast traffic on a LAG 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.
To enable local link bias on a LAG bundle:
[edit]
user@switch# set interface
aex aggregated-ether-options local-biaswhere aex is the name of the aggregated Ethernet link bundle.
For instance, to enable local link bias on aggregated Ethernet interface ae0:
[edit]
user@switch# set interface
ae0 aggregated-ether-options local-bias
