iSCSI Optimization Commands 519Default ConfigurationiSCSI well-known ports 3260 and 860 are configured by default but can beremoved as any other configured target.Command ModeGlobal Configuration mode.User Guidelines• When working with private iSCSI ports (not IANA assigned iSCSI ports3260/860), it is recommended to specify the target IP address as well, sothe switch will only snoop frames with which the TCP destination port isone of the configured TCP ports, AND their destination IP is the target'sIP address. This way the CPU is not be falsely loaded by non-iSCSI flows(if by chance other applications also choose to use these {un-reserved}ports).• When a port is already defined and not bound to an IP address, and youwant to bind the port to an IP address, first remove the port by using theno form of the command and then add it again, this time together withthe relevant IP address.• Target names are only for display when using the show iscsi command.These names are not used to match (or for doing any sanity check) withthe iSCSI session information acquired by snooping.• A maximum of 16 TCP ports can be configured either bound to IP or not.ExampleThe following example configures TCP Port 49154 to target IP address172.16.1.20.console(config)#iscsi target port 49154 address172.16.1.20show iscsiUse the show iscsi command in Privileged EXEC mode to display the iSCSIconfiguration.
