BOOTP/DHCP Relay

BOOTP and DHCP allow stations to obtain boot and TCP/IP information dynamically. The relay agent allows them to obtain this information when the BOOTP/DHCP server is not on the same IP interface as the end station. You can configure the switch so that the messages are forwarded from one interface to the appropriate server on another interface.

DNS Relay

The Domain Name System (DNS) is used to map names to IP addresses. DNS relay enables the switch to act as a DNS cache or proxy. It forwards DNS requests to DNS servers only if it can’t resolve the name from its cache.

If you enable DNS relay on the switch, you can specify a primary and secondary DNS server to forward requests that the switch cannot resolve. You can also specify that requests destined for specific DNS servers should be first serviced by looking in the switch’s table.

Packet Forwarding

The switch maintains a forwarding table. This table contains the relationship between a destination MAC or IP address and the Ethernet port or gateway router the destination resides on. This information is used to forward packets. This reduces the traffic congestion on the network, because packets, instead of being transmitted to all ports, are transmitted to the destination port only. For example, if Port 1 receives a packet destined for a station on Port 2, the switch transmits that packet through Port 2 only, and transmits nothing through the other ports. This process is referred to as “learning” the network topology.
