When setting up multiple policies using any of the default polic y actions ID’s 2 to 9 (i.e.
Standard_Service, Bronze_Service, etc) a lower precedence polic y with a drop action,
(i.e. Drop_Traffic), the Drop_Traffic action will effect the higher precede nce policies. The
end result is all the higher precedence policies will also be dro pped. The reason for this
is each of the default actions, with the exception of Drop_Traffic, uses a drop action of
deferred-Pass. A drop action of deferred-Pass specifies that a traffic flow decision will
be deferred to other installed policies.
To make a policy behave somewhat similar to stop-on-match, you will have to create a new
action with a drop action of dontDrop (JDM) or disable (CLI).
• Statistics accumulation support – a limited number of counters are a vailable for tracking
statistics. Specifically, 32 counters are available per port f or tracking matching (no
metering specified) /in-profile (metering specified) traffic statis tics. A total of 63 counters
are available (per port) to track out-of-profile statistics, with the ca veat that these
counters are associated with the metering component and flows sharing the s ame meter
on the same port use the same counter for statistics.

The valid precedence range for QoS policies is from 1 to 15. However, d epending on
the application enabled, the valid precedence range can change as Q oS shares
resources with other switch applications including DHCP Relay, MAC Security, IP Fix,
IGMP, EAPOL, EAP multihost (5530-24TFD only), OSPF, IP Source Guar d, and ADAC.
Please use the command ‘show qos diag’ to view the mask utilization p er port.

In release 4.1, FCS November 2004, the system default actions (e.g. bron ze, silver,
gold, etc.) will be changed from deferred-Pass to dontDrop.
