Default command level
2: System level
Parameters
text
: Specifies an interface description, a case-sensitive string of 1 to 80 characters.
When you specify an interface description, follow these guidelines:
•
An interface description can be a mixture of English characters and other Unicode characters. The
mixed description cannot exceed the specified string length.
•
To use Unicode characters or symbols in an interface description, install the corresponding IME and
log in to the device through remote login software that supports the character type.
•
Each non-English Unicode character or symbol (non-English characters) takes the space of two
regular characters. When the length of a description string reaches or exceeds the maximum line
width on the terminal software, the software starts a new line. This might break a Unicode character
into two parts and create garbled characters at the end of a line.
Examples
# Set the description for interface loopback 0 to
loopback0
.
<Sysname> system-view
[Sysname] interface loopback 0
[Sysname-loopback0] description loopback0
