88 / 324 page ![]() Functional Descriptions VMDS-10488 VSC7511 Datasheet Revision 4.2 73 VID 32 12 Frame’s VID if frame is tagged, otherwise port default. S1_NORMAL: VID is taken from tag pointed to by VCAP_CFG.S1_VLAN_INNER_TAG_ENA. DEI 44 1 Frame’s DEI if frame is tagged, otherwise port default. S1_NORMAL: DEI is taken from tag pointed to by VCAP_CFG.S1_VLAN_INNER_TAG_ENA. PCP 45 3 Frame’s PCP if frame is tagged, otherwise port default. S1_NORMAL: PCP is taken from tag pointed to by VCAP_CFG.S1_VLAN_INNER_TAG_ENA. INNER_TPID 48 1 TPID for inner tag. 0: Customer TPID. 1: Service TPID (88A8 or programmable). INNER_VID 49 12 Frame’s inner VID if frame is double tagged. INNER_DEI 61 1 Frame’s inner DEI if frame is double tagged. INNER_PCP 62 3 Frame’s inner PCP if frame is double tagged. Table 42 • Specific Fields for IS1 Full Key S1_NORMAL_IP6 Field Name Bit Width Description Layer 2 Information L2_SMAC 65 48 Frame’s source MAC address. Use destination MAC address if VCAP_CFG.S1_DMAC_DIP_ENA is set for ingress port. Layer 3 Information L3_DSCP 113 6 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 8 IPv6 next header. Layer 4 Information TCP_UDP 255 1 Frame type flag. Set if frame is IPv4/IPv6 TCP or UDP frame. TCP 256 1 Frame type flag. Set if frame is IPv4/IPv6 TCP frame. L4_RNG 257 8 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.
