Management Plane Access Control (MPAC) policies can be
applied to sub-interfaces, to interfaces, or globally to filter packets
destined for the CPU.
Usage Scenario
MPAC can be configured to
filter packets destined for the CPU, thereby helping protect network
devices against Denial of Service (DoS) attacks.
Pre-configuration Tasks
Before configuring
MPAC, configure link layer protocol parameters and IP addresses for
interfaces to ensure that the link layer protocol on the interfaces
is in the Up state.
