Link Aggregation Configuration
This chapter describes how to configure link aggregation. Link aggregation bundles multiple Ethernet links into a logical link to increase bandwidth, improve reliability, as well as load balance traffic.
- Introduction to Link Aggregation
- Principles
- Applications
- Configuration Task Summary
- Licensing Requirements and Limitations for Link Aggregation
- Default Settings
- Configuring Link Aggregation in Manual Mode
Link aggregation implements load balancing, increases bandwidth, and improves transmission reliability. - Configuring Link Aggregation in LACP Mode
Link aggregation implements load balancing, increases bandwidth, and improves transmission reliability. - Configuring Preferential Forwarding of Local Traffic in a CSS
On a network where a CSS and an Eth-Trunk are used, configuring the Eth-Trunk to preferentially forward local traffic increases bandwidth use efficiency between devices in the CSS and improves traffic forwarding efficiency. - Creating an Eth-Trunk Sub-interface
To transmit both Layer 2 and Layer 3 services over the same physical link, create a sub-interface on a Layer 2 Eth-Trunk. - Configuring an E-Trunk
The Enhanced Trunk (E-Trunk) protocol implements link aggregation between multiple devices to improve link reliability between devices. It is an extension to LACP which only implements link aggregation on a single device. - Maintaining Link Aggregation
Maintaining link aggregation includes monitoring the link aggregation running status and clearing LACPDU statistics. - Configuration Examples
