S Vlan and C VLAN

Hi all,

This is my first email to this great group, I want to as if anybody can help me in designing of the network in terms of S vlan and C vlan, what is differences and what is recommended for what and any useful data.


Wrong list to ask that question. After you have a network you can share your experiences and discuss how to operate it. The "O" in NANOG stands for Operators.

BTW your email was marked as confidential so this response does not exists


"S-TAG" and "C-TAG" are used exclusively for networks that need
double VLAN tagging, where S belongs to the provider and C belongs to
the customer.

Please see IEEE 802.1ad standard, and your network vendor's
documentation regarding their implementation of the standard.

I think it is possible I might have received this message in error.
