Network requirements
As shown in Figure 6 , a company uses a switch named Device to interconnect all its departments. 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 priority mapping table, and priority marking to implement the
plan in Table 4 .
