Create 'access-list' for use with 'line vty'

높음레벨 1수동 검토cisco-ios

설명

Access lists control the transmission of packets on an interface, control Virtual Terminal Line (VTY) access, and restrict the contents of routing updates. The Cisco IOS software stops checking the extended access list after a match occurs. VTY ACLs control what addresses may attempt to log in to the router. Configuring VTY lines to use an ACL, restricts the sources where a user can manage the device. CIS assessment: Manual. Reported as SKIP with review instructions.
