Appendix C Using the Command-Line Interface Syntax Formatting Syntax Formatting Command syntax descriptions use the following conventions: Table C-1 Syntax Conventions Convention bold italics [x] | [x | y] {x | y} [x {y | z}] Description Bold text indicates commands and keywords that you enter literally as shown. Italic text indicates arguments for which you supply values. Square brackets enclose an optional element (keyword or argument). A vertical bar indicates a choice within an optional or required set of keywords or arguments. Square brackets enclosing keywords or arguments separated by a vertical bar indicate an optional choice. Braces enclosing keywords or arguments separated by a vertical bar indicate a required choice. Nested sets of square brackets or braces indicate optional or required choices within optional or required elements. Braces and a vertical bar within square brackets indicate a required choice within an optional element. Abbreviating Commands You can abbreviate most commands down to the fewest unique characters for a command; for example, you can enter wr t to view the configuration instead of entering the full command write terminal, or you can enter en to start privileged mode and conf t to start configuration mode. In addition, you can enter 0 to represent 0.0.0.0. Command-Line Editing The FWSM uses the same command-line editing conventions as Cisco IOS software. You can view all previously entered commands with the show history command or individually with the up arrow or ^p command. Once you have examined a previously entered command, you can move forward in the list with the down arrow or ^n command. When you reach a command you wish to reuse, you can edit it or press the Enter key to start it. You can also delete the word to the left of the cursor with ^w, or erase the line with ^u. The FWSM permits up to 512 characters in a command; additional characters are ignored. Command Completion To complete a command or keyword after entering a partial string, press the Tab key. The FWSM only completes the command or keyword if the partial string matches only one command or keyword. For example, if you enter s and press the Tab key, the FWSM does not complete the command because it matches more than one command. However, if you enter dis, the Tab key completes the command disable. OL-20748-01 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM C-3
