Disable Proxy ARP on all Layer 3 Interfaces
Opis
Proxy ARP is the technique in which one host, usually a router, answers ARP requests intended for another machine on a different network segment (vlan or subnet). By faking its identity, the router accepts responsibility for routing packets to the real destination. Audited against the output of 'show running-config' (run 'terminal length 0' first; do not use 'show running-config all', which adds default values).

Kako se ispravlja
Metod ispravke: Smernica ili zakrpa infrastrukture
! Proxy ARP is disabled on all interfaces by default, and that configuration does not appear in the running or saved configuration. Proxy ARP only appears in the configuration if it is enabled (which is not desired in most cases). To disable this on an interface if it is enabled: no ip proxy-arp for instance: int vlan 9 no ip proxy-arp
