The unit for bandwidth is kilobits/sec
When I checked that for policy-map it is in kilobits/sec, but when I checked the serial interface it was not,,,any hint about this ?
Router(config-pmap-c)#bandwidth ?
<8-2000000> Kilo Bits per second
percent % of Available Bandwidth
Router(config-pmap-c)#exit
Router(config-pmap)#exit
Router(config)#
Router(config)#interface serial 0/0
Router(config-if)#bandwidth ?
<1-10000000> Bandwidth in kilobits
