Parameters
command: Specifies the keywords and arguments of a display command. To display available
keywords and arguments, enter display ?.
Usage guidelines
By numbering each output line from a display command, you can easily identify the lines of interest.
Each line number is displayed as a 5-character string and might be followed by a colon (:) or hyphen
(-). If you specify both | by-linenum and | begin regular-expression for a display command, a
hyphen is displayed for all lines that do not match the regular expression.
Examples
# Display VLAN 999 settings, with each output line identified by a number.
<Sysname> display vlan 999 | by-linenum
1: VLAN ID: 999
