SYSTEM VERIFICATION

Verifying Proxy ARP is Operational

3.If the communication between two IP devices across the WAN is successfully established, then the proxy ARP feature is properly working.

4.If the communication can not be established, display the ARP cache on the IP host devices to see what MAC addresses are mapped to the target IP address. On many operating systems, the arp -acommand displays the ARP cache. If the target IP addresses are mapped into the nearest CyberSWITCH’s MAC addresses respectively, for example, on Host A, Host B’s IP address is mapped to the CyberSWITCH A’s MAC address, then the proxy ARP feature is working properly, but basic IP routing may not be operational. Establish the basic IP connectivity first, then try to use the proxy ARP feature. If the target IP addresses are not shown or are mapped to MAC addresses that are not then refer to the Proxy ARP Operation section of the Problem Diagnosis chapter.
