Configuring the Number of Ping Packets
By default, the DHCP server pings a pool address twice before assigning the address to a requesting client. If the ping is unanswered, the DHCP server assumes (with a high probability) that the address is not in use and assigns the address to the requesting client. To change the number of ping packets the DHCP server should send to the pool address before assigning the address, use the following command in global configuration mode:
Command
Purpose
Router(config)# ip dhcp ping packets number
Specifies the number of ping packets the DHCP server sends to a pool address before assigning the address to a requesting client. The default is two packets.
بالنسبة لل gratuitous ARP فهى Broadcast packet بيرسلها Host بالايبى بتاعه لكل destination كى يتأكد ان ما فى حد معاه بنفس الايبى بتاعه .
وبالتوفيق ان شاء ،،،
