Entering a question mark "?" at the system prompt (console prompt) displays a list of commands available for that particular command mode.
www.dell.com | support.dell.com When starting a session, the initial mode is the User EXEC mode. Only a limited subset of commands are available in the User EXEC mode. This level is reserved for tasks that do not change the configuration. To enter the next level, the Privileged EXEC mode, a password is required. The Privileged EXEC mode gives access to commands that are restricted on User EXEC mode and provides access to the device Configuration mode.
The user-level prompt consists of the device host name followed by the angle bracket (>). Console> The default host name is Console unless it was changed using the hostname command in the Global Configuration mode. Privileged EXEC Mode Privileged access is password protected to prevent unauthorized use because, many of the privileged commands set operating system parameters. The password is not displayed on the screen and is case sensitive. Privileged users enter directly into the Privileged EXEC mode.
www.dell.com | support.dell.com Global Configuration Mode Global Configuration mode commands apply to features that affect the system as a whole, rather than just a specific interface. The configure Privileged EXEC mode command is used to enter the Global Configuration mode. To enter the Global Configuration mode, at the Privileged EXEC mode prompt enter the command configure and press . The Global Configuration mode prompt is displayed.
• Ethernet — Contains commands to manage port configuration. The interface ethernet Global Configuration mode command is used to enter the Interface Configuration mode to configure an Ethernet type interface. • Port Channel — Contains commands to configure port-channels, for example, assigning ports to a port-channel. Most of these commands are the same as the commands in the Ethernet interface mode, and are used to manage the member ports as a single entity.
www.dell.com | support.dell.com NOTICE: When using HyperTerminal with Microsoft® Windows 2000,ensure that Windows® 2000 Service Pack 2 or later is installed.With Windows 2000 Service Pack 2, the arrow keys function properly in HyperTerminal’s VT100 emulation. Go to www.microsoft.com for information on Windows 2000 service packs. For more information, see Dell™ PowerConnect™ 3400 Series User's Guide.
To assist in using the CLI, there is an assortment of editing features. The following features are described: • Terminal Command Buffer • Command Completion • Keyboard Shortcuts Copying and Pasting Text Up to 100 lines of text (i.e., commands) can be copied and pasted into the device. NOTE: This editing features are for Telnet only. NOTE: It is the user’s responsibility to ensure that the text copied into the device consists of legal commands only.
www.dell.com | support.dell.com There is a standard default number of commands that are stored in the buffer. The standard number of 10 commands can be increased to 216. By configuring 0, the effect is the same as disabling the history buffer system. For information about the command syntax for configuring the command history buffer, see history size. To display the history buffer, see show history.
CLI Command Conventions When entering commands there are certain command entry standards that apply to all commands. The following table describes the command conventions. Convention Description [] In a command line, square brackets indicate an optional entry. {} In a command line, curly brackets indicate a selection of compulsory parameters separated by the | character. One option must be selected.

The gvrp enable Global Configuration mode command enables GVRP globally. To disable GVRP on the device, use the no form of this command.
www.dell.com | support.dell.com Syntax gvrp enable no gvrp enable Default Configuration GVRP is disabled on all interfaces. Command Mode Interface Configuration (Ethernet, port-channel) mode User Guidelines • An access port does not dynamically join a VLAN because it is always a member in only one VLAN. • Membership in an untagged VLAN is propagated in the same way as in a tagged VLAN. That is, the PVID is manually defined as the untagged VLAN VID.
Command Mode Interface configuration (Ethernet, port-channel) mode User Guidelines • • The following relationship must be maintained between the timers: – Leave time must be greater than or equal to three times the join time. – Leave-all time must be greater than the leave time. Set the same GARP timer values on all Layer 2-connected devices. If the GARP timers are set differently on Layer 2-connected devices, the GARP application will not operate successfully.
