ProSafe M5300 Switch
• Mark IP DSCP - This lists the keywords for the known DSCP values from which one
can be selected. The list includes 'other' as an option for the remaining values.
• Simple Policy - Use this attribute to establish the traffic policing style for the specified
class. This command uses single data rate and burst size resulting in two outcomes
(conform and violate).
4. If you select the Simple Policy attribute, you can configure the following fields:
• Color Mode - This lists the color mode. The default is 'Color Blind'.
• Color Blind
• Color Aware
Color Aware mode requires the existence of one or more color classes that are valid
for use with this policy instance. A valid color class contains a single, non-excluded
match criterion for one of the following fields (provided the field does not conflict with
the classifier of the policy instance itself):
• CoS
• IP DSCP
• IP Precedence
• Committed Rate - This value is specified in the range 1 to 4294967295
kilobits-per-second (Kbps).
• Committed Burst Size - This value is specified in the range 1 to 128 KBytes. The
committed burst size is used to determine the amount of conforming traffic allowed.
• Conform Action - This lists the actions to be taken on conforming packets per the
policing metrics, from which one can be selected. The default is 'send'.
• Violate Action - This lists the actions to be taken on violating packets per the policing
metrics, from which one can be selected. The default is 'send'.
• For each of the above Action Selectors one of the following actions can be taken:
• Drop - These packets are immediately dropped.
• Mark IP DSCP - These packets are marked by DiffServ with the specified DSCP
value before being presented to the system forwarding element. This selection
requires that the DSCP value field be set.
• Mark CoS - These packets are marked by DiffServ with the specified CoS value
before being presented to the system forwarding element. This selection requires
that the Mark CoS value field be set.
• Send - These packets are presented unmodified by DiffServ to the system
forwarding element.
• Mark IP Precedence - These packets are marked by DiffServ with the specified IP
Precedence value before being presented to the system forwarding element. This
selection requires that the Mark IP Precedence value field be set.
