Q-in-Q Tag Removal.
When a packet enters a Trunk port, the 3202 will check the packet TPID value against
the TPID value configured in the 3202. If there is no match, when the packet Egresses from an Access port,
the packet will remain intact.
Figure 23. Unmatched VLAN Tag
Alternatively, if the packet TPID and the TPID configured in the 3202 match, then the 3202 will remove that
packet when it egresses from an Access port.

Quality of Service (QoS)
Quality of Service (QoS)
refers to both a network's ability to deliver data with minimum delay, and the net-
working methods used to control the use of bandwidth. Without QoS, all traffic date is equally likely to be
dropped when the network is congested. This can cause a reduction in network performance and mark the net-
work inadequate for time-critical application such as video-on-demand.

QoS (Quality of Service) is used to decide which devices can get priorities to pass though the Model 3202 once
the bandwidth is exhausted or fully saturated.
