iSCSI Optimization Commands
519
Default Configuration
iSCSI well-known ports 3260 and 860 are configured by default but can be
removed as any other configured target.
Command Mode
Global Configuration mode.
User Guidelines
• When working with private iSCSI ports (not IANA assigned iSCSI ports
3260/860), it is recommended to specify the target IP address as well, so
the switch will only snoop frames with which the TCP destination port is
one of the configured TCP ports, AND their destination IP is the target's
IP 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 you
want to bind the port to an IP address, first remove the port by using the
no form of the command and then add it again, this time together with
the 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) with
the iSCSI session information acquired by snooping.
• A maximum of 16 TCP ports can be configured either bound to IP or not.
Example
The following example configures TCP Port 49154 to target IP address
172.16.1.20.
console(config)#iscsi target port 49154 address
172.16.1.20
show iscsi
Use the show iscsi command in Privileged EXEC mode to display the iSCSI
configuration.
