RTAG_OFFSET = 0xF1C1
SN_NUM_GREATER = 1
FRMREPEN = 1

CB_ON_DEST = 1
CB_SID_ON = 0 
MACADDR = 0x112233445566
MASK = 0x0000FFFFFFFFFFFFF
SRCPORT = 4
DESTPORT = Port 1 & Port 2

TAGPORTS = Port 1 & Port 2 
GENSEQNUM = 1

I have configured, this in Switch 1 of SJA1110 

I also tried configuring same in Switch - 2 also first but its not working 
and i changed to different configuring 

CB_ON_DEST = 1
CB_SID_ON = 0  &  1
MACADDR = 0x112233445566
MASK = 0x0000FFFFFFFFFFFFF
SRCPORT = Port 1 & Port 2
DESTPORT = Port 4


CB Sequence Generation and Individual Recovery Table
TAG_PORTS = Disabled all the Ports
IND_REC_PORTS = Port 4 Enabled
SEQ_REC_PORTS = Port 4 Enabled
SEQRECOFFSET = 0
IND_REC_TIMEOUT = 0
GENSEQNUM = 0 
 
I have configured this 
but generally when I don't configure this i will be transmitting a CAN message which will be getting converted to UDP Ethernet Packet and In Another Switch Ethernet Packet will be getting back to CAN Message 
but when i configure this when I transmit a CAN Message its not getting converted as UDP Ethernet Packet 
EthType its showing F1C1 which is not valid as UDP Ethernet Packet so its getting Rejected 
so what i need to do for Transmitting as a UDP Ethernet Packet
I tried changing EthType as 0x0800 also but its affecting the Initial switch Configuration the Packets are coming as Corrupted Ethernet Packet so its not showing Ethernet Packet 

It would be helpful if you give me a suggestion overcome this issue

Hello @Abrar_23,

Since I have not received answer in the other post (2053180) I will ask also in this one.

Is this topic still of your interest?

 

Thanks.
