Cisco AVC Rule Configuration

C.

When configuring Cisco Application Visibility and Control (AVC) on a Cisco Wireless LAN Controller (WLC), the engineer can prioritize certain types of traffic such as Cisco IP cameras that use the wireless network. To achieve this, the engineer must create a rule and configure certain elements within that rule.

The element that the engineer would configure in a rule to prioritize Cisco IP cameras that use the wireless network is the "mark". This is because marking allows the engineer to specify a value that is assigned to packets that match the criteria of the rule. This value can then be used by other features such as Quality of Service (QoS) to prioritize traffic.

To configure marking for Cisco IP cameras, the engineer would need to follow these steps:

1. Create an application group that includes the specific applications used by Cisco IP cameras.
2. Create a class map that matches traffic from the IP address range of the Cisco IP cameras and assigns it to the application group created in step 1.
3. Create a policy map that uses the class map created in step 2 and sets the mark value to a specific value, such as 60.
4. Apply the policy map to the WLAN or WLANs where the Cisco IP cameras are used.

By following these steps, the engineer can prioritize traffic from Cisco IP cameras that use the wireless network by marking the packets with a specific value. Other features such as QoS can then use this value to prioritize the traffic accordingly.

Therefore, the correct answer to the question is C. mark.
