VCAP_CFG.S1_DMAC_DIP_ENA is set for ingress port.

Layer 3 Information

L3_DSCP

113

Frame’s DSCP value. The DSCP value may have been

translated during basic classification. For more

information, see QoS, DP, and DSCP Classification,

page 53.

L3_IP6_SIP

119

128

Source IP address.

Use destination IP address if

VCAP_CFG.S1_DMAC_DIP_ENA is set for ingress port.

L3_PROTO

247

IPv6 next header.

Layer 4 Information

TCP_UDP

255

Frame type flag.

Set if frame is IPv4/IPv6 TCP or UDP frame.

TCP

256

Frame type flag.

Set if frame is IPv4/IPv6 TCP frame.

L4_RNG

257

Range mask with one bit per range. A bit is set, if the

corresponding range is matched.

Range types: SPORT, DPORT, SPORT or DPORT, VID,

DSCP.

Input to range checkers:

SPORT/DPORT: From frame

VID: From frame if tagged, otherwise port’s VID

DSCP: Translated DSCP from the basic classification.

See Range Checkers, page 94.
