E810-xxvam2

[Greif]

I have a packet with a tagged VLAN. I have tried different setups but am still missing something, since I am not receiving the packet that I sent. I do not want the tag to be stripped from the packet. In essence I just want the packet to pass thru without any conditioning being done.

What should the registers be set to. I have tried changing the “showIV and L2TSel and many other registers. Any idea’s ?

Hayat, thanks for the response

checking on the promiscuous mode that was mentioned.

Can we go a little deeper to the chip level. Dealing with a tagged VLAN on the receive packet.

The E810 Datasheet section 7.12.3.3 states that the tag extraction rules are controlled by the following:

 VSI_TSR.STRIPTAG, VSI_TSR.SHOWTAG, and VSI_TSR.SHOWPRIONLY bit fields.

Within Table 7-290 Tag Extraction Example, the document talks about “SHOWIV and L2TSEL”:

We, have SHOWIV and L2TSEL set to a 1, 0 respectfully.  Which selects Inner VLAN on L2TAG1.

However, I believe this only pertains to different cases assuming the first tag is an STag and the second tag is a VLAN.

We don’t have a Stag only a typical 802.1 (8100) vlan tag.

If the VSI_TSR.STRIPTAG, VSI_TSR.SHOWTAG, and VSI_TSR.SHOWPRIONLY bit fields control the extraction rules how do you set this for “DO nothing” leave the packet as is.
