IPv6 uses multicast-based NDP.ĭoes the switch internally keep track of IP addresses matching the MAC addresses? Initially when computer A only knows about the computer B's IP address?įor IPv4, broadcast-based ARP is used to resolve an IP address to its corresponding MAC address (for MAC-based networks): A broadcasts an ARP request with B's IP address, B replies with its interface MAC address.

However, you can use the management software to configure more advanced features that can improve switch efficiency and overall network performance. The NETGEAR switch functions as a simple switch without the management software. If no frame has been sent from a node, its MAC is initially unknown and the switch needs to mimick a repeater hub by flooding the unknown frame to all its ports but the source port. The NETGEAR switch contains an embedded web server and management software for managing and monitoring switch functions. If so, how does it know the destination MAC address initially?Ī switch ("multiport MAC bridge") learns locations of MAC nodes from the source addresses they use in the frames they send. This switch can act as a DHCP server for an isolated network. It is fine to use DHCP (e.g., from the switch, or from a Crestron server), Static/Manual addressing, or Self-Assigned addresses. This article only applies to Netgear M4250-series switches. Whether higher layers use IPv4, IPv6 or anything else doesn't concern the switch. Ensure that you have a Netgear M4250-series switch. A basic switch forwards frames by destination MAC address only. When computer A on a local network wants to communicate with computer B for example through the unmanaged switch, does the switch simply just forward the Ethernet frames to computer B? 元 switches use IP addresses for 元 forwarding = routing as well.
Some L2 switches also support limited 元/IP functionality like ACLs. An unmanaged switch doesn't use/care for/understand IP addresses at all.Ī managed L2 switch uses IP addresses for management only.
