Parameter
bandwidth: Available bandwidth of the interface. It is in kbps (1 to 1000000). By default,
this value is the actual interface baud rate or speed for a physical interface, the total
bandwidth of the channel set for a logical serial interface that is formed by bundling in
T1/E1 or MFR, or 64 kbps for a logical interface like virtual template or VE.
Description
Use the qos max-bandwidth command to configure the maximum interface bandwidth
used when CBQ enqueues packets.
Use the undo qos max-bandwidth command to cancel the bandwidth configuration.
The maximum available bandwidth of an interface is preferred to be smaller than the
real available bandwidth of the physical interfaces or the logical links. For a serial
interface, the value defaults to 64 kbps. To modify it, you can change the interface rate
using the baudrate command to 2.048 Mbps for example, and then set a new value,
115.2 kbps for example.
Example
# Set the bandwidth of virtual-template 1 to 128 kbps.
[3Com -Virtual-Template1] qos max-bandwidth 128
