HPE Networking switches support DHCPv4 and DHCPv6 snooping. Configuring both versions helps protect your entire network by blocking unintended or rogue DHCPv4 and DHCPv6 servers. By default, all ports are untrusted. Once configured, DHCP server packets are forwarded only if received on a trusted por...

A DHCP-snooping-capable device monitors DHCP packets and uses information carried in the packets to create a DHCP snooping binding table. This table records hosts' media access control (MAC) addresses, IP addresses, IP address lease time, virtual local area network (VLAN) IDs, and interface ...
