Generation of UDP Ethernet Packet when configuring IEEE802.1 CB (FRER)

Abrar_23 — Thu, 27 Feb 2025 18:03:36 GMT

I have configured, CB Sequence Generation and Individual recovery Table, L2 Lookup Table and I configured General Parameters --> RTAG_TYPE = 0xF1C1/ 0x0800 i tried two option, enabled SEQNUM_GENERATOR -- ENABLE & CB_EN -- ENABLE

But when Generating an Ethernet Frame there was some misalignment is happening in generation of Ethernet Frames
It should generate frame
[Dst MAC] [Src MAC] [EtherType (0x0800)] [IPv4 Header] [UDP Header] [Payload]
But the Frame is getting Generated is
[Dst MAC] [Src MAC] [RTAG_TYPE (0xF1C1)] [Some extra bytes] [EtherType (0x0800)] [IPv4 Header] ...
below is my sample data
11 22 33 44 55 66 4C 4C 43 45 41 46 F1 C1 00 00 00 04 08 00
45 00 00 2C 00 04 40 00 10 11 6C BB 7F 00 00 01 7F 00 00 01
05 DC 05 DC 00 18 CA 20 0C 03 20 C8 00 00 00 08 FF 0F FF FF
FF FF FF FF 00 00

I have configured based on the Documentation -- "AH SJA1110 TCAM and TSN"

due to this issue its unable to generate a UDP Frame as Expected which is causing the issue
so how can i overcome this issue

Abrar

Hello @Abrar_23,

Sorry for the late response. about your problem, I see you created a similar post here: 2053054, are the two post about the exact same problem? if so, is it ok for you if we keep the discussion only in this one?

Thanks
