that depends on the ios,
some take 75% as the available bw and others do no such reservation.
check the archieves.

Hello group,

If we have the following configuration:

class-map match-all ftp
 match protocol ftp
class-map match-all telnet
 match protocol telnet
!
policy-map qos
 class ftp
  bandwidth 100
 class telnet
  bandwidth 50
 class class-default
  bandwidth 50
!
int s0/0
 bandwith 250
 ip rtp priority 16384 16383 50
 service-policy output qos
!

What should be the correct value of max-reserved-bandwidth parameter to
config over the serial 0/0 interface?, 80%?

Thank's in advance.
