Solved: Re: QinQ - VLAN injection

jan.klicka · ‎09-26-2005

Hello,

we need to inject some traffic to QinQ tunnel carrying customers' traffic. I haven't found any paper describing this situation, so I was thinking about how to do it:

- customer has SP VLAN ID 100, encapsulation dot1q on SP backbone.

- when I configure some aceess port with VLAN 100, it will be member of customers' native VLAN

- when I do "cable loopback" between two interfaces of SP box like this, I'll be able to inject VLAN 200 and 300 to customers' QinQ tunnel:

interface FastEthernet0/23

switchport access vlan 100

switchport mode dot1q-tunnel

switchport nonegotiate

no cdp enable

!

interface FastEthernet0/24

switchport trunk encapsulation dot1q

switchport trunk allowed vlan 200,300

switchport mode trunk

switchport nonegotiate

no cdp enable

I'm not sore about correctness of approach. Is there any other way how to do it?

Thanks for comment. Honza Klicka

Hello,

that's exactly, what I meant. The only problem is, that I need this kind of features on Cat 3750 or 6506.

Thank you

The Catalyst 3750 added QinQ (or 802.1q tunneling) support as of IOS 12.2(25)SE (released ca. November 2004). See http://www.cisco.com/en/US/partner/products/sw/iosswrel/ps5012/prod_bulletin0900aecd801bfd43.html for the announcement. A configuration guide is at http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3750m/12225ey/3750mscg/swtunnel.htm (for 3750 Metro) or http://www.cisco.com/univercd/cc/td/doc/product/lan/cat3750/12225se/3750scg/swtunnel.htm (for non-Metro 3750).

The 6500 series also suports QinQ. see http://www.cisco.com/en/US/partner/products/hw/switches/ps708/products_qanda_item09186a00801eb824.shtml. A configuration guide is at http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/122sx/swcg/dot1qtnl.htm.
