Chapter 10 Network QoS for vNICs 207
See the ACL mark option in “Setting Actions” on page 214.
Note – 802.1p and IP Precedence mapping is supported, but all queues currently
have the same priority. The Oracle Fabric Interconnect uses a weighted fair queue
(WFQ) algorithm to determine packet priorities.
DSCP Mapping on 10GbE Cards
DiffServ (RFC 2474) redefines the TOS byte by taking the top 6 bits of the top byte as
a Differentiated Services Code Point (DSCP). Hardware sets up a DSCP mapping
table to map DSCP values to queues. All undefined values are mapped to the queue
corresponding to the DF.
DSCP Mapping is supported on all versions of GE card. The following table shows
the supported DSCP services, values, and the vNIC queue that maps to the service.
