[c-nsp] QinQ Layer2 QoS - 3550?

[Rolf Mendelsohn]

Hi Guys,

We have a number of Cisco 3550's doing QinQ on a Metro-E network.

I was wondering whether anybody is succesfully copying the 802.1P info from 
the Inner Tag, to the Outer Tag.

From the following doc:
http://www.cisco.mn/en/US/docs/switches/lan/catalyst3550/software/release/12.2_44_se/configuration/guide/swtunnel.html

The priority field on the metro tag is set to the interface class of service 
(CoS) priority configured on the tunnel port (the default is zero if none is 
configured).

IEEE 802.1Q Tunneling and Other Features 
 Although IEEE 802.1Q tunneling works well for Layer 2 packet switching, there 
are incompatibilities between some Layer 2 features and Layer 3 switching. 
 •Tunnel ports do not support IP access control lists (ACLs). 
 •Layer 3 quality of service (QoS) ACLs and other QoS features related to 
Layer 3 information are not supported on tunnel ports. MAC-based QoS is 
supported on tunnel ports. 

What does one need to support Layer-2 QoS on QinQ, newer Juniper EX switches? 
Cisco 3750's?

Thanks,
Rolf
