Parameters
text
: Specifies a description for a VLAN or VLAN interface. The string can include case-sensitive letters,
digits, special characters (including ~ ! @ # $ % ^ & * ( ) - _ + = { } [ ] | \ : ; " ' < > , . /), 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.
NOTE:
•
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 and creating
garbled characters at the end of a line.
Description
Use
description
to change the description of the VLAN or VLAN interface.
Use
undo description
to restore the default.
•
For a VLAN, the default description is the VLAN ID. For example,
VLAN 0001
.
•
For a VLAN interface, the default description is the name of the interface. For example,
Vlan-interface1 Interface
.
You can configure a description to describe the function or connection of a VLAN or VLAN interface,
which is very helpful when a large number of VLANs are created on the device.
