Command Scripting The CLI can be used as a programmable management interface. To facilitate this function, any characters entered after the character are treated as a comment and ignored by the CLI. Also, the CLI allows the user to disable session timeouts. CLI Command Notation Conventions When entering commands there are certain command-entry notations which apply to all commands. The following table describes these conventions as they are used in syntax definitions. Convention [ ] { } Italic + Screen Display all Description In a command line, square brackets indicate an optional entry. In a command line inclusive brackets indicate a selection of compulsory parameters separated by the | character. One option must be selected. For example: flowcontrol {auto|on|off} means that for the flowcontrol command either auto, on or off must be selected. Indicates a variable. Any individual key on the keyboard. Any combination of keys pressed simultaneously on the keyboard. Indicates system messages and prompts appearing on the console. Indicates a literal parameter, entered into the command as it is. Interface Naming Conventions The conventions for naming interfaces in CLI commands are as follows: • Unit#/Interface ID - each interface is identified by the Unit# followed by a symbol and then the Interface ID. For example, 2/g10 identifies the gigabit port 10 within the second unit. • Unit# - the unit number is used only in a stacking solution where a number of switches are stacked to form a virtual switch. In this case, the Unit # identifies the physical switch identifier within the stack. • Interface ID - is formed by the interface type followed by the interface number. For example, 2/g10 identifies the gigabit port 10 on the second unit; 1/g1 identifies the fast Ethernet port 1 on the first unit within the stack. • Interface Types - the following interface types are defined. g stands for gigabit Ethernet port (for example, g2 is the gigabit port 2). xg stands for 10 Gigabit Ethernet port (for example, xg2 is the 10 gigabit Ethernet port 2). 111
