IPv4 Device Access Policy Definition

Version:

The control plane of Cisco WAN Edge devices process the data traffic for local services like, SSH and SNMP, from a set of sources. It is important to protect the CPU from device access traffic by applying the filter to avoid malicious traffic.

Access policies define the rules that traffic must meet to pass through an interface.
