Usage Notes:
• Classifiers on LAGs only support filtering and remarking; not metering.
• LAGs do not support egress port rate limiting.
• Ingress Meters (TRAFFIC DESCRIPTORs) are limited to 1 per classifier. Their actions on out-of-profile packets are
NCFORWARD (the default), NCDROP, an NCCOUNT.
• All interfaces support p-bit mapping to queues.
• All interfaces support only Strict Priority, Tail-drop queuing discipline.
• FE2/GE2/FE10/FX10/ADSL24 - Not supported with double tagging of 802.3 packets. Rejects classifiers with
ETHFORMAT=802.3x if the classifier contains an INNERVID or INNERVPRIORITY rule. Rejects classifiers with
ETHFORMAT=802.3x if the classifier contains is an HVLAN configured on that port. Any generic classifier that does not
specify an EthFormat of 802.3 will NOT match 802.3 packets. In other words, classifiers with no ETHFORMAT rule or a
rule of ETHFORMAT=ANY will not match 802.3 packets.
• GE3 - Not supported with double tagging of 802.3 packets. Rejects classifiers with ETHFORMAT=802.3x if the classifier
contains an INNERVID or INNERVPRIORITY rule. Rejects classifiers with ETHFORMAT=802.3x if the classifier contains
is an HVLAN configured on that port.
• FE2, GE2, FE10, FX10, ADSL24, GE3 - If a classifier contains a rule that specifies one of the 802.3 EthFormats, a filter will
be created that will match 802.3 packets. The iMAP system assumes that if the user specifies 802.3x and IP-related fields,
that this is an indicator that IP uses LLC-SNAP and as a result the system allows for an 8-byte SNAP header. The system
does NOT support 802.3 headers of any size other than 8 bytes when matching IP-related fields.
• FE2, GE2, FE10, FX10, ADSL24, GE3 - Rejects classifiers containing INNERVID or INNERVIDPRIORITY rule(s) if there is
NOT a HVLAN configured on that interface/port.
• FE2, GE2, FE10, FX10, ADSL24, GE3 - If a classifier fails to be installed due to any reason related to the configuration of
other features on that port (such as, an HVLAN being configured on that port), the system will keep the data related to

a. Not the interface for traffic management; this is done by the ONU, which is the UNI interface port. The EPON2
models the ONU as an Network Access product extension.
b. For ETHFORMAT=ANY or no ETHFORMAT, the rule will result in a match for either EthII or 802.3 formats.
c. QoS policies (SLAs) allow limiting of services at specific rates.
d. Classifier capacity is an approximation. The features enabled on a port or interface, such as such as IGMP,
DHCPRELAY, VLAN (for per-VLAN UFO and HVLAN), EPSR, INTERFACE (TAGALL option for HVLAN),
ACCESSLIST, and CLASSIFIER, classifiers on surrounding ports, content of the user classifiers, and many other
factors influence the number of classifiers available on a given port or interface.
