CHAPTER 1 ISCLI Basics Your switch is ready to perform basic switching functions right out of the box. Some of the more advanced features, however, require some administrative configuration before they can be used effectively. This guide describes the individual ISCLI commands available for the switch. The ISCLI provides a direct method for collecting switch information and performing switch configuration.
RackSwitch G8124 Command Reference Each mode provides a specific set of commands. The command set of a higher-privilege mode is a superset of a lower-privilege mode — all lower-privilege mode commands are accessible when using a higher-privilege mode. Table 1-1 lists the ISCLI command modes. Table 1-1 ISCLI Command Modes Command Mode/Prompt Command used to enter or exit User EXEC Default mode, entered automatically on console.
RackSwitch G8124 Command Reference Table 1-1 ISCLI Command Modes Command Mode/Prompt Command used to enter or exit ACL MAC Configuration G8124 (config-ext-macl)# Enter the Access Control List (ACL) IP MAC Extended Configuration mode.
RackSwitch G8124 Command Reference Global Commands Some basic commands are recognized throughout the ISCLI command modes. These commands are useful for obtaining online Help, navigating through the interface, and for saving configuration changes. For help about a specific command, type the command, followed by ? (question mark). Table 1-2 Description of Global Commands Command Action ? Help may be requested at any point in a command by entering a question mark ( ? ).
RackSwitch G8124 Command Reference Table 1-2 Description of Global Commands Command Action [no] prompting Enables or disables CLI prompts. Prompts allow you to step through complex configurations, and provide supporting information. You can disable prompting to facilitate CLI scripting. The default value is enabled. show history This command brings up the history of the last 10 commands. show who Displays a list of users who are currently logged in.
RackSwitch G8124 Command Reference Command Line Interface Shortcuts Command Abbreviation Most commands can be abbreviated by entering the first characters which distinguish the command from the others in the same mode.
RackSwitch G8124 Command Reference User Access Levels To enable better switch management and user accountability, three levels or classes of user access have been implemented on the switch. Levels of access to CLI, Web management functions, and screens increase as needed to perform various switch management tasks. Conceptually, access classes are defined as follows: user: Interaction with the switch is completely passive—nothing can be changed on the switch.
RackSwitch G8124 Command Reference Table 1-3 User Access Levels User Account Description and Tasks Performed Password User The User has no direct responsibility for switch management. He or she can view all switch status information and statistics, but cannot make any configuration changes to the switch. user Operator Interaction with the switch is completely passive—nothing can be changed on the switch.

RackSwitch G8124 Command Reference Port Mirroring Port Mirroring commands are used to configure, enable, and disable the monitor port. When enabled, network packets being sent and/or received on a target port are duplicated and sent to the monitor port. By attaching a network analyzer to the monitor port, you can collect detailed information about your network performance and usage. The switch supports up to four monitor ports. Port mirroring is disabled by default.
RackSwitch G8124 Command Reference Uplink Failure Detection Configuration Uplink Failure Detection (UFD) supports network fault tolerance in network adapter teams. Use these commands to configure a Failure Detection Pair of one Link to Monitor (LtM) group and one Link to Disable (LtD) group. When UFD is enabled and a Failure Detection Pair is configured, the switch automatically disables ports in the LtD if it detects a failure in the LtM.
RackSwitch G8124 Command Reference Failure Detection Pair Configuration Use these commands to configure a Failure Detection Pair, which consists of one Link to Monitor (LtM) and one Link to Disable (LtD). When the switch detects a failure on the LtM, it automatically disables the ports in the LtD. The following table describes the Failure Detection Pair (FDP) configuration commands. Table 4-64 FDP Commands Command Syntax and Usage ufd fdp enable Enables the Failure Detection Pair (FDP).

To view an example of the command output, see page 190. Command mode: All show backup-configuration Displays the parameters set for the backup configuration.
CHAPTER 5 Operations Commands Operations commands generally affect switch performance immediately, but do not alter permanent switch configurations. For example, you can use Operations commands to immediately disable a port, with the understanding that when the switch is reset, the port returns to its normally configured operation. These commands allow you to alter switch operational characteristics without affecting switch configuration.
RackSwitch G8124 Command Reference Operations-Level Port Options Operations-level port commands are used for temporarily disabling or enabling a port, and for re-setting the port. Table 5-2 Port Operations Commands Command Syntax and Usage interface port shutdown Temporarily disables the port. The port will be returned to its configured operation mode when the switch is reset.
CHAPTER 6 Boot Options To use the Boot Options commands, you must be logged in to the switch as the administrator. The Boot Options commands allow you to perform the following actions: Select a switch software image to be used when the switch is next reset. Select a configuration block to be used when the switch is next reset. Download or uploading a new software image to the switch via TFTP.

RackSwitch G8124 Command Reference Updating the Switch Software Image The switch software image is the executable code running on the switch. A version of the image ships with the switch, and comes pre-installed. As new versions of the image are released, you can upgrade the software running on your switch. To get the latest version of software available for your switch, go to: http://downloads.bladenetwork.net/media/PHPs/members/ racks_landing_page.php Click on software updates.
RackSwitch G8124 Command Reference Loading new Software to Your Switch The switch can store up to two different software images, called image1 and image2, as well as boot software, called boot. When you load new software, you must specify where it should be placed: either into image1, image2, or boot. For example, if your active image is currently loaded into image1, you would probably load the new image software into image2.
RackSwitch G8124 Command Reference Selecting a Software Image to run You can select which software image (image1 or image2) you want to run in switch memory for the next reboot. 1. In Global Configuration mode, enter: G8124(config)# boot image {image1|image2} 2. Enter the name of the image you want the switch to use upon the next boot. The system informs you of which image set to be loaded at the next reset: Next boot will use switch software image1 instead of image2.
RackSwitch G8124 Command Reference Selecting a Configuration Block When you make configuration changes to the switch, you must save the changes so that they are retained beyond the next time the switch is reset. When you perform a save operation (copy running-config active-config), your new configuration changes are placed in the active configuration block. The previous configuration is copied into the backup configuration block. There is also a factory configuration block.
RackSwitch G8124 Command Reference Using the Boot Management menu The Boot Management menu allows you to switch the software image, reset the switch to factory defaults, or to recover from a failed software download. You can interrupt the boot process and enter the Boot Management menu from the serial console port. When the system displays Memory Test, press the key and the key at the same time. The Boot Management menu appears. Resetting the System ... Memory Test .............................
