Table 17 lists the criteria that can be matched for the various MAC frame types.
Service Ingress Classification on 7210 SAS-K - IP and MAC Packet fields
The IP and MAC match criteria can be very basic or quite detailed. IP and MAC match criteria are
constructed from policy entries. An entry is identified by a unique, numerical entry ID. A single
entry cannot contain more than one match value for each match criteria. Each match entry has an
action which specifies: the forwarding class of packets that match the entry. The entries are
evaluated in numerical order based on the entry ID from the lowest to highest ID value. The first
entry that matches all match criteria has its action performed.
Table 18, Service Ingress QoS Policy IP Match Criteria for 7210 SAS-K, on page 61 lists the
packets fields that can be used for match-criteria used for SAP ingress classification.
Table 16: MAC Match Ethernet Frame Types
Note: The default frame type configured is Ethernet - II
Frame Format Description
802.3 IEEE 802.3 Ethernet frame. Only the source MAC, destination MAC and
IEEE 802.1p value are compared for match criteria.
802dot2-llc IEEE 802.3 Ethernet frame with an 802.2 LLC header. Only the source
MAC and destination MAC address are compared for match criteria.
802dot2-snap IEEE 802.2 Ethernet frame with 802.2 SNAP header. Only the source MAC
and destination MAC address are compared for match criteria.
Ethernet-II Ethernet type II frame where the 802.3 length field is used as an Ethernet
type (Etype) value. Etype values are two byte values greater than 0x5FF
(1535 decimal).
