How to design Link-Aggregation on switch

Link Aggregation supports manual mode and LACP mode, it depends on whether LACP is used.

In this project we recommend to use the LACP mode, as The Link Aggregation Control Protocol (LACP) can improve fault tolerance of the Eth-Trunk, implement backup, and ensure high reliability of member links.

LACP provides a standard negotiation mechanism for a switching device so that the switching device can be configured to automatically form and start aggregated links. After an aggregated link is formed, LACP is responsible for maintaining the link. If link aggregation conditions or requirements change, LACP can adjust or remove the aggregated link.

For example, there are two GE links between router and switch, which will configured with LACP Eth-Trunk, the typical configuration is as below:

Table 1-1 Link Aggregation Congiguration Template

interface eth-trunk 1

 description Connect To PE   Router

 mode lacp

interface XGigabitEthernet0/0/1

 eth-trunk 1

interface XGigabitEthernet0/0/2

 eth-trunk 1
