Network requirements
As shown in Figure 8 , the company’s enterprise network interconnects all departments through Device.
The network is described as follows:
• The marketing department connects to GigabitEthernet 1/0/1 of Device, which sets the 802.1p
priority of traffic from the marketing department to 3.
• The R&D department connects to GigabitEthernet 1/0/2 of Device, which sets the 802.1p priority
of traffic from the R&D department to 4.
• The management department connects to GigabitEthernet 1/0/3 of Device, which sets the 802.1p
priority of traffic from the management department to 5.
Configure port priority, 802.1p-to-local mapping table, and priority marking to implement the plan as
described in
Table 3 .
