Switching

Hi ,

I am trying to setup Q-In-Q on a EX4300 with software 13.2X50-D17 and Enhanced Layer 2 Software license based on the following topic:

http://www.juniper.net/techpubs/en_US/junos13.3/topics/task/configuration/qinq-tunneling-ex-series-cli-els.html

but I am receiving many error messages like below:

[edit vlans v22 interface]
'ge-0/0/1.22'
interface with vlan-id/vlan-id-list cannot be added to a vlan with a vlan-id/vlan-id-list configured
[edit vlans v22 interface]
'ge-0/0/1.22'
interface with vlan-id-list/inner-list cannot be added to a vlan with a vlan-id/vlan-tags configured
[edit vlans v22 interface]
'ge-0/0/1.22'
interface with input/output vlan-maps cannot be added to a routing-instance with a vlan-id/vlan-tags configured
error: configuration check-out failed: (statements constraint check failed)

I have one access port where the customer us connected (ge-0/0/1) and one uplink for the service vlan (xe-0/2/1) and the follomh configuration:

Service VLAN:

set vlans v22 vlan-id 22
set vlans v22 interface xe-0/2/1.22
set interfaces xe-0/2/1 flexible-vlan-tagging
set interfaces xe-0/2/1 encapsulation extended-vlan-bridge
set interfaces xe-0/2/1 unit 22 vlan-id 22

Customer:

set vlans v22 interface ge-0/0/1.22
set interfaces ge-0/0/1 flexible-vlan-tagging
set interfaces ge-0/0/1 encapsulation extended-vlan-bridge
set interfaces ge-0/0/1 unit 22 vlan-id-list 100-500
set interfaces ge-0/0/1 unit 22 input-vlan-map push
set interfaces ge-0/0/1 unit 22 output-vlan-map pop

Appreciate any help as I have tried different combinations and sequences to do this but no progress.

according to the error you cannot have a vlan-id for the vlans. I am reading the message, the ELS is not my area of expertise.

Try this

delete vlans v22 vlan-id 22

Thanks 🙂 this was the trick 

Hey, I'm kind of having the same issue but with 14.1 software.  EX4300 switch, ELS 14.1X53 

When I'm applying the push/pop statements it gives me this...

interface with vlan-id-list and input-vlan-map swap/pop is not supported

Plus getting some of the errors you did as well.  

If you are still on here, can I see your complete config layout on this Q-in-Q?   

Below is a working Q-in-Q config for an EX4600 (ELS) switch.  Config should be same for EX4300 (again ELS switch).  Hopefully this can help you.

SVLAN == 4020

CVLAN ==1-4000

ae0.4020 == double tagged interface

ae1.0 == single tagged interface

{master:0}[edit vlans]

mit@ServiceEdge-C2A# show LLAN

interface ae0.4020;

interface ae1.0;

domain-type bridge;

{master:0}[edit vlans]

mit@ServiceEdge-C2A# top show interfaces ae0

description Uplink-Edge;

flexible-vlan-tagging;

mtu 9192;

encapsulation extended-vlan-bridge;

aggregated-ether-options {

    lacp {

        periodic fast;

    }

}

unit 4020 {

    vlan-id 4020;

}

{master:0}[edit vlans]

mit@ServiceEdge-C2A# top show interfaces ae1

flexible-vlan-tagging;

encapsulation extended-vlan-bridge;

aggregated-ether-options {

    lacp {

        active;

        periodic fast;

    }

}

unit 0 {

    vlan-id-list 1-4000;

    input-vlan-map push;

    output-vlan-map pop;

}

Hey!  Sorry I didnt reply sooner.  Thanks for the info!  I actually solved my issue myself.  The first issue was the same as your with the S-VLAN not need the vlan-id assigned to it.  They don't make that clear in the documents online.  Secondly, I didnt notice the slight differences in one of the commands with the push/pop.  lol  My dumb mistake.  Thanks!!!  

Understood. But: Into which Vlan the frames are mapped then, if there is no vlan-id set?
