Configuring an Eth-Trunk to Preferentially Forward Local Traffic in a Stack
Context
On a network where a stack and an Eth-Trunk are used, configuring an Eth-Trunk to preferentially forward local traffic increases bandwidth use efficiency between devices in the stack and improves traffic forwarding efficiency.
The S5720I-10X-PWH-SI-AC and S5720I-6X-PWH-SI-AC do not support this configuration.
Pre-configuration Tasks
Before configuring an Eth-Trunk to preferentially forward local traffic, complete the following tasks:
Establish a stack.
- Ensure that member interfaces of the local Eth-Trunk have sufficient bandwidth to forward local traffic.
Procedure
- Run system-view
The system view is displayed.
- Run interface eth-trunk trunk-id
The view of the Eth-Trunk that needs to be configured to preferentially forward local traffic is displayed.
This operation is not required on the S5735-L, S5735S-L, S5735S-L-M, S5735-S, and S5735S-S.
- Run local-preference enable
The Eth-Trunk is configured to preferentially forward local traffic.
By default, an Eth-Trunk forwards traffic preferentially through local member interfaces.
This function is only valid for known unicast packets, and is invalid for unknown unicast, broadcast, and multicast packets.
