Title

The Cisco ACI must be configured to protect against or limit the effects of denial-of-service (DoS) attacks by employing control plane protection.

Description

<VulnDiscussion>The route processor (RP) is critical to all network operations because it is the component used to build all forwarding paths for the data plane via control plane processes. It is also instrumental in ongoing network management functions that keep the routers and links available for providing network services. Any disruption to the RP or the control and management planes can result in mission-critical network outages. A DoS attack targeting the RP can result in excessive CPU and...

Fix Text (Documentation Requirement)

Protect against known types of DoS attacks on the route processor by implementing a CoPP policy. To meet this requirement, configure the COPP policy on each device, QOS to ensure the correct traffic is being dropped, and verify all l3 outs have the correct contracts applied to them. These policies must be applied to the Leaf and or interface policies accordingly. CoPP Policy: Fabric >> Access Policies >> Policies >> Switch >> CoPP Pre-Filter for Leaf / CoPP Leaf Fabric >> Access Policies >> Policies >> Interface >> CoPP Interface QOS: Since there are so many locations and settings required for this aspect, reference the QOS documentation to access these settings: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/kb/Cisco-APIC-and-QoS.html Configure L3Out contrac...
