Filters and QoS Configuration for ERS 5500
Technical Configuration Guide	v2.0	NN48500-559

When setting up multiple policies using any of the default policy actions ID’s 2 to 9 (i.e. Standard_Service, Bronze_Service, etc) a lower precedence policy with a drop action, (i.e. Drop_Traffic), the Drop_Traffic action will effect the higher precedence policies. The end result is all the higher precedence policies will also be dropped. 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-Passspecifies 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 available for tracking statistics. Specifically, 32 counters are available per port for tracking matching (no metering specified) /in-profile (metering specified) traffic statistics. A total of 63 counters are available (per port) to track out-of-profile statistics, with the caveat that these counters are associated with the metering component and flows sharing the same meter on the same port use the same counter for statistics.

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

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