[j-nsp] RES: RES: QFX 5100 and Q-in-Q

[Alexandre Guimaraes]

Chuck,

       The way that are you doing works well (I call it as dot1q tagging services), The way that I need to use, L2TP doesn't works. (QinQ services)

       Due the limited "QinQ", I need to keep CPE at customers to deal with QinQ/L2TP services.

Att.

I'm using Q-in-Q as a tap aggregation function. Port mirrors and/or optical taps from other devices are connected to QFX5100 ports which encapsulate the foreign traffic with Q-in-Q, then flood the traffic to all ports in the same outer VLAN. Analyzers are connected to the output ports. It may be that L2 protocols like PVST+ are not passing through, but that doesn't matter much for my use case: set interfaces xe-0/0/0 description "MIRROR1 INPUT from device foo" set interfaces xe-0/0/0 flexible-vlan-tagging set interfaces xe-0/0/0 native-vlan-id 2 set interfaces xe-0/0/0 mtu 9216 set interfaces xe-0/0/0 encapsulation extended-vlan-bridge set interfaces xe-0/0/0 unit 2 vlan-id-list 1-4094 set interfaces xe-0/0/0 unit 2 input-vlan-map push set interfaces xe-0/0/0 unit 2 input-vlan-map vlan-id 2 set interfaces xe-0/0/0 unit 2 output-vlan-map pop set interfaces xe-0/0/0 unit 2 family ethernet-switching filter output DISCARD set interfaces xe-0/0/24 description "MIRROR1 OUTPUT to analyzer bar" set interfaces xe-0/0/24 flexible-vlan-tagging set interfaces xe-0/0/24 mtu 9216 set interfaces xe-0/0/24 encapsulation extended-vlan-bridge set interfaces xe-0/0/24 unit 2 vlan-id-list 1-4094 set interfaces xe-0/0/24 unit 2 input-vlan-map push set interfaces xe-0/0/24 unit 2 input-vlan-map vlan-id 2 set interfaces xe-0/0/24 unit 2 output-vlan-map pop set interfaces xe-0/0/24 unit 2 family ethernet-switching filter input DISCARD set vlans MIRROR1 interface xe-0/0/0.2 set vlans MIRROR1 interface xe-0/0/24.2 set vlans MIRROR1 switch-options no-mac-learning On Sat, Mar 25, 2017 at 12:22:40AM +0000, Alexandre Guimaraes wrote: > Chuck, > > > Could you please share portion of your QinQ configuration?
