[name of experiment]

Port aggregation configuration.

[purpose of the experiment]

Understand how port aggregation works and how to configure port aggregation on the switch.

[background description]

Suppose an enterprise uses two switches to form a local area network, because a lot of data traffic is forwarded across the switch.

Therefore, it is necessary to increase the transmission bandwidth between switches and achieve link redundancy backup.

Two network cables are used to interconnect between changers, and the corresponding two ports are aggregated into a logical port, which is to be done on the switch.

Properly configured to achieve this goal.

[demand Analysis]

Port aggregation needs to be implemented on the redundant link between the two switches, and Trunk is set on the aggregation port to

Increase the bandwidth of the network backbone link.

[experimental Topology]

When connecting to the network according to the topology diagram, note that after both switches have been configured with port aggregation, connect the two switches

get up. If you connect first and then configure, it may cause a broadcast storm and affect the normal operation of the switch.

[experimental equipment]

One layer 3 switch

One layer 2 switch

[preliminary knowledge]

The basic configuration method of the switch, the working principle and configuration method of VLAN, the working principle and configuration method of Trunk

Configuration method of SVI port, working principle and configuration method of aggregation port

[experimental principle]

Port aggregation (Aggregate-port), also known as link aggregation, refers to the physical transfer of multiple ports between two switches.

Connect and aggregate multiple links into a single logical link. So as to increase the link bandwidth and solve the problem of bandwidth introduction in the switching network.

The problem of network bottleneck. Multiple physical links can be backed up redundant to each other, and any one of them will not be affected if it is disconnected.

Forward data normally in response to other links.

Port aggregation follows the standards of the IEEE 802.3ad protocol.

[experimental steps]

Step 1: configure the hostnames and management IP of the two switches

Step 2: configure aggregation ports on both switches

Step 3: set the aggregation port to Trunk

Step 4: set the load balancing mode of the aggregation port

Step 5: verify the configuration
