Control Plane ACL

Mô tả

A default control plane ACL is provided and applied to the system control-plane. The default control-place ACL is read-only, but you can create and assign a different ACL to the system control-plane if customization is needed. However, it is strongly recommended to use the default control-plane ACL as a template for any custom ACL that you may apply to ensure protocol and management operations function correctly. The default control plane ACL filters all IP traffic inbound and outbound on any management interface. SSH, Telnet, NTP, SNMP, IP protocols, and logging/matching on management traffic are done by this ACL. CIS assessment: Manual. Reported as SKIP with review instructions.
