Mirroring also requires additional register settings for the individual ports. Refer to the Port N: Port Switch Ingress Control Registers (0xN800 - 0xN8FF). Address: 0x035E Size: 8 bits Bits Description Type Default 7 RESERVED RO 0b 6:4 When IPv4 / IPv6 DSCP field is 0x3D, use this value for priority R/W 000b 3 RESERVED RO 0b 2:0 When IPv4 / IPv6 DSCP field is 0x3C, use this value for priority R/W 000b Address: 0x035F Size: 8 bits Bits Description Type Default 7 RESERVED RO 0b 6:4 When IPv4 / IPv6 DSCP field is 0x3F, use this value for priority R/W 000b 3 RESERVED RO 0b 2:0 When IPv4 / IPv6 DSCP field is 0x3E, use this value for priority R/W 000b Address: 0x0370 Size: 8 bits Bits Description Type Default 7 RESERVED RO 0b 6 IGMP Snooping Enable (IPv4) 1 = IGMP snooping is enabled. All IGMP packets will be forwarded to the host port. 0 = IGMP snooping is disabled. R/W 0b 5:4 RESERVED RO 00b 3 MLD Snooping Option 1 = Snooping criteria: IPv6 next header = 43, 44, 50, 51 or 60; or next header = 0 and hop-by-hop next header = 43, 44, 50, 51 or 60. 0 = Snooping criteria: IPv6 next header = 1 or 58; or next header = 0 and hop-by-hop next header = 1 or 58. R/W 0b 2 MLD Snooping Enable (IPv6) 1 = MLD snooping is enabled. All MLD packets will be forwarded to the host port. 0 = MLD snooping is disabled. R/W 0b 1 RESERVED RO 0b |
