Q-in-Q pass-through

[pwenger]

Hi,

can someone tell me what this mean "Q-in-Q pass-through". Is there a document for this feature on CCO or somewhere else?

Best regards

Hi,

I think that might be Cisco 802.1Q Tunneling (also called Cisco 802.1Q-in-Q).

See http://www.cisco.com/en/US/customer/about/ac123/ac114/ac173/ac224/about_cisco_packet_technology0900aecd800b19a7.html

and

http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/sft_6_1/configgd/dot1qtnl.pdf

for details.

Regards,

Milan

Milan,

thanks for the answer, but what does "pass-through" mean?

Hi,

where did it came from?

If you mean the Cisco Catalyst 4500 Series Supervisor Engine II-Plus Data Sheet http://www.cisco.com/en/US/customer/products/hw/switches/ps4324/products_data_sheet09186a0080197424.html,

I'd think it just says the module supports 802.1Q-in-Q.
