A Switch Connects to a Server

A Switch Connects to a Server

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

In addition to the configuration notes in Licensing Requirements and Limitations for Link Aggregation, be aware of the following points:

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

    For example, if an Intel network adapter is used, 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 Eth—Trunk of the switch.

Different types of network adapters use different link aggregation configurations. For details, refer to the network adapter operation guide.
