Q-in-Q Tagging.
If a packet enters an Access port with a single tag or double tag, the 3202 will check the
packet TPID value against the TPID value configured in the 3202. If the TPID values do not match, the
3202 will add another VLAN tag when this packet egresses from a Trunk port (see
figure 22
). If the TPID
does match, no additional VLAN tag is added.
