[f-nsp] Support for tag-type on FESX?

[Jorik Jonker]

Hi,

Indeed, a FESX is able to set tag-type per 12 ports (per ASIC?)
10/100/1000 and per 10G port. I have found that it was unable to
'translate' tag types:

Tag-type 0x9100 e 13
Vlan 100
  Tagged e 1 e 13

[A] --- 0x8100 vid 100 --- [port1 FESX port13] --- 0x9100 vid 100 ---
[B]

It appeared that B receives 0x8100-tagged frames sent from A, although
one would expect this to be 0x9100. 

The version of the FESX (424 PREM and 624 PREM) is 05.0.00T3e3. Could be
that other versions do not have this issue.

You cannot set this on individual ports on fesx. It is set per 'port
region' 12 ports at the time.
At least older sw even have a bug on this and either the entire box runs
8100 or 9100 or xxxx.

Haven't been playing with it for some time so I'am not sure if it have
been fixed in newer releases.
I guess that this also explains why the sh tag-type do not work :-)

Hi,
 setting up something like below:

<customer tagged port with VLANs>----tagged 0x8100----[FESX]----tagged
0x9100----[FESX] ----tagged 0x8100----<customer tagged port with
VLANs>

note there is no untagged/tagged mismatching so we are not trying to
do qinq with the customer vlans.

The above works for other Foundry platforms just fine, for FESX tho it
seems to put 0x8100 onto the wire in the middle, which, doesn't work.

Does the FESX not support having different ports with different
tag-types?

(Of course, the tag-type is per dma, so the ports are allocated to
ensure they are using the different tag-types)

Has anyone tried this or have it working?

I'm also a little concerned that the 'sh tag-type' command doesn't
work. These are all documented as being features.

Cheers
Steve
