Epipe service with QinQ SAP and dot1q SAP

[fortune123]

Hi all,


I am still a newbie to the ALU world and your assistance will be greatly appreciated .
I need to find out if it is possible to have an Epipe service with QinQ SAP and dot1q SAP on the same physical port (1/1/3).
Please see below for more info.

S/W Release 7.0 Rev.08 on a SAS-T

epipe 1 svc-sap-type qinq-inner-tag-preserve customer 1 create
sap 1/1/3:10.45 create
no shutdown
exit
sap 1/1/3:85 create
no shutdown
exit
no shutdown

Hi,

I don't believe you can do it as you show above, as the physical port will either be configured as qinq or dot1q, so will complain on one of the commands.

The only way (to my knowledge) to achieve above is to enable port as qinq, then for the second sap, use sap 1/1/3:85.*, this should do it I think (but will obviously also match any qinq packets too with outer tag of 85.

Cheers

Dear Paramount,

Thank you for your response,Please correct me if my understanding is incorrect.

sap 1/1/3:85.* - means , i will match traffic with an outer tag of 85 and an inner tag of any(all tags).

Now what will happen to traffic ingressing that epipe with a single tag of 85?

[mivens]

* matches a tag of <0..4095> or untagged.

So 85.* matches ethernet frames with an outer tag of 85 and with any inner tag or with no inner tag.

From 13.0R1 there is also the 'null' keyword to match 'no tag' if "new-qinq-untagged-sap" is enabled.

Dear mivens

Thank you for your response , unfortunately the feature is not supported on 7210 SAS-T running TiMOS-B-7.0.R8 code.

Please see below error

*A:test>config>service>epipe$ sap 1/1/13:850.* create
MINOR: SVCMGR #218 Feature not supported

it should work, just make a new epipe:
epipe 1 customer 1 create

Hey There ,

i found a work around if you configure as below (i) it doesn't work
(i)
epipe 1 svc-sap-type qinq-inner-tag-preserve customer 1 create
*A:test>config>service>epipe$ sap 1/1/13:850.* create
MINOR: SVCMGR #218 Feature not supported

but you configure the epipe as svc-sap-type any works

epipe 1 customer 1 svc-sap-type any create
*A:test>config>service>epipe$ sap 1/1/13:850.* create

Code: Select all

svc-sap-type any

so the conclusion is command in the code, isn't it?.

Does anyone see the following?

*A:NS1221C0668>config>service# epipe 500 customer 1 svc-sap-type qinq-inner-tag-preserve create
MINOR: CLI The service-id does not correspond to the specified service type.

I am trying to have my inner tag preserved when traversing the network.

Are you sure the service-id 500 is not already used by other service?
