ZyXEL Communications n/a User Manual

DSL & IAD CLI Reference Guide

Use these commands to configure bandwidth management (BWM) settings on the ZyXEL 
Device.

The following table describes the values required for many commands. Other values are 
discussed with the corresponding commands.

The following section lists the commands for this feature.     

Table 14   Bandwidth Management Command Input Values

The bandwidth management interface name includes lan, wan, dmz, and wlan. 
The interfaces to which you can apply bandwidth management vary by ZyXEL 
Device model. 

This is a class name. Enter a descriptive name of up to 20 alphanumeric 
characters, including spaces.

This is a class number. Each class for each interface has an unique number. The 
number format is "xx.xx.xx.xx ... xx" and the range of xx is from 01 to 98. Each 
".xx” is a subclass. And the length of "xx.xx.xx.xx ..." is the depth of this class. 
Different model supports different class depth.

Table 15   Bandwidth Management Commands

bm class <interface> <add|mod> 

<class-number> <bandwidth 

<bandwidth>> [name <class-name>] 

[priority <priority>] [borrow 

<on|off>]

Adds or modifies a class for the specified interface with the specified 
bandwidth. You can also configure the name, priority, and whether or 
not the class can borrow bandwidth from its parent class.

add|mod

: Add or modifies the class. When you delete a class, it 

also deletes its sub-classes.

: The unit is bps and its minimum is 30 Kbps. You can 

add “K” (or “k”) to specify Kbps or “M” (or “m”) to specify Mbps. If you 
do not specify the bandwidth, the default value is 100 Mbps.

: Specify a descriptive name of up to 19 alphanumeric 

characters.

: Sets the class priority ranging from 0 (the lowest) to 7 

(the highest).

borrow <on|off>

: Enables or disables bandwidth borrowing.

bm class <interface> del <class-

number>

Removes the specified class from the specified interface. When you 
delete a class, it also deletes its sub-classes.

bm config [load|save|clear]

Loads, saves, clears BWM configuration from/to the permanent
