Chapter 11 Configuring Quality of Service on the ML-Series Card
Configuring QoS
ML_Series (config-pmap-c)# bandwidth
{
bandwidth-kbps
| percent
percent
}
Specifies a minimum bandwidth guarantee to a traffic class in periods of
congestion. A minimum bandwidth guarantee can be specified in kbps or
by a percentage of the overall available bandwidth.
Valid choices for the ML-Series cards are:
• Rate in kilobits per second
• Percent of total available bandwidth (1 to 100)
If multiple classes and bandwidth actions are specified in a single policy
map, they must use the same choice in specifying bandwidth (kilobits or
percent).
Note When using the bandwidth command, excess traffic (beyond the
configured commit) is allocated any available bandwidth in
proportion to the relative bandwidth commitment of its traffic
class compared to other traffic classes. Excess traffic from two
classes with equal commits has equal access to available
bandwidth. Excess traffic from a class with a minimum commit
might receive only a minimum share of available bandwidth
compared to excess bandwidth from a class with a high commit.
Note The true configurable bandwidth in kilobits per second is per port
and depends on how the ML-Series card is configured. The show
interface command shows the maximum bandwidth of a port (for
example, BW 100000 Kbit). The sum of all bandwidth and priority
actions applied to the interface, plus the cos priority-mcast
bandwidth, is not allowed to exceed the maximum bandwidth of
the port.
