A Switch Connecting to a Server Through Link Aggregation

A Switch Connecting to a Server Through Link Aggregation

In Figure 3-16, two or more network adapters of the server are aggregated to form a network adapter group to improve server bandwidth and reliability. This grouping can implement load balancing and redundancy.

In addition to the configuration notes in Licensing Requirements and Limitations for Link Aggregation, pay attention to the following points:

  • Network adapters of the server must be the same model.
  • The link aggregation modes on the server and access device must match.

    Intel network adapter is used as an example. A server often uses static or IEEE 802.3ad dynamic link aggregation. When the server uses static link aggregation, the access device must use the manual mode. When the server uses IEEE 802.3ad dynamic link aggregation, the access device must use the LACP mode.

  • When a server needs to obtain the configuration file from the remote file server through a switch and link aggregation needs to be used, run the lacp force-forward command on the link aggregation interface of the switch.
NOTE:

Different models of network adapters use different link aggregation configurations. See the corresponding network adapter operation guide for more information.
