Chapter 1 Configuring SAN Port Channels
Information About SAN Port Channels
Figure 1-4 illustrates how exchange-based load balancing works. When the first frame in an exchange is
received for forwarding on an interface, link 1 is chosen by a hash algorithm. All remaining frames in
that particular exchange are sent on the same link. For exchange 1, no frame uses link 2. For the next
exchange, link 2 is chosen by the hash algorithm. Now all frames in exchange 2 use link 2.
