(See Example 20-4.) The RcvDataFieldSize will be set to the maximum 2048 if the MTU is increased on the Gigabit Ethernet interface that corresponds to this iSCSI remote node. Use the Target FCID field to verify that the local port, rather than a remote port that is reached through an ISL link, is used for the storage target to avoid suboptimal access to storage.
