Qos Policy - 3Com 3012 Command Reference Manual

3Com Router Command Reference Guide Addendum for V1.2
Description
Using qos max-bandwidth command, you can set the maximum bandwidth of an
interface. Using undo qos max-bandwidth command, you can remove the setting of
the maximum bandwidth.
By default, the maximum bandwidth is not configured for all interfaces.
The bandwidth set by this command is only a logic value, not the actual bandwidth of
an interface. It is suggested that this value not be configured on a common physical
interface, as it is only used for CBQ bandwidth calculation. The actual bandwidths of
some interfaces, such as virtual template interface, physical interface configured with
Line-Rate and DTE interface used for bandwidth negotiation, are unavailable.
Therefore this command is usually configured on these interface.
Note: When the actual available bandwidth (the maximum bandwidth multiplied by the
percentage of reserved bandwidth) of an interface is smaller than the sum of the
bandwidths (including class-related bandwidths of CBQ and the sum of RTP
bandwidths) configured by the user, the configuration of enabling CBQ or RTP on the
interface will be automatically canceled due to lack of bandwidth. If the configured
bandwidth only fits into one of above requirements, the CBQ configuration will be
reserved preferentially.
For the related command, see qos reserved-bandwidth.
Example
Set the bandwidth of Virtual-Template 1 to 128kbit/s.
