L3_IP6_DIP

205

Overloaded fields for different frame types:

LLC frame: L3_IP6_DIP = PAYLOAD[7:14]

SNAP frame: L3_IP6_DIP = PAYLOAD[5:12]

IPv4 frame: L3_IP6_DIP = destination IP address, bits [31:0]

IPv6 frame: L3_IP6_DIP = destination IP address, bits [63:0]

OAM, ARP or ETYPE frame: L3_IP6_DIP = PAYLOAD[8:15]

L3_IP6_SIP_MSB

269

IPv6 frame: L3_IP6_SIP_MSB = source IP address,

bits [127:112]

L3_IP6_SIP

285

Overloaded fields for different frame types:

LLC frame: L3_IP6_SIP = [CTRL, PAYLOAD[0:6]]

SNAP frame: L3_IP6_SIP = [PID[2:0], PAYLOAD[0:4]]

IPv4 frame: L3_IP6_SIP = source IP address, bits [31:0]

IPv6 frame: L3_IP6_SIP = source IP address, bits [63:0]

OAM, ARP or ETYPE frame: L3_IP6_SIP = PAYLOAD[0:7]

Layer-4 Information

TCP_UDP

349

Frame type flag.

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

TCP

350

Frame type flag.

Set if frame is IPv4/IPv6 TCP frame.

L4_SPORT

351

TCP/UDP frame’s source port.

L4_RNG

367

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.
