Parameters
text
: Specifies the description of a VLAN or VLAN interface. The string can include case-sensitive
letters, digits, special characters such as tilde (~), exclamation point (!), at sign (@), pound sign (#),
dollar sign ($), percent sign (%), caret (^), ampersand sign (&), asterisk (*), left brace({), right brace
(}), left parenthesis ((), right parenthesis ()), left bracket ([), right bracket (]), left angle bracket (<),
right angle bracket (>), hyphen (-), underscore(_), plus sign (+), equal sign (=), vertical bar (|), back
slash (\), colon (:), semi-colon (;), quotation marks ("), apostrophe ('), comma (,), dot (.), and slash (/),
spaces, and other Unicode characters and symbols.
•
For a VLAN, this is a string of 1 to 32 characters.
•
For a VLAN interface, this is a string of 1 to 80 characters.
When you specify a description, follow these guidelines:
•
Each Unicode character takes the space of two regular characters.
•
To use Unicode characters or symbols in an interface description, install the specific input
method editor and log in to the device through remote login software that supports the character
type.
•
When the length of a description string reaches or exceeds the maximum line width on the
terminal software, the software starts a new line, possibly breaking a Unicode character into two.
As a result, garbled characters may be displayed at the end of a line.
