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.
Example Set the bandwidth of virtual-template 1 to 128 kbps.

Description 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.
