addition, exporting packet headers allows a sFlow analyzer to monitor all types of traffic flowing across the switch; Note the ARP and IPV6 traffic displayed in Sflowtrend in addition to the tcp/udp flows. Visibility into Layer 2 traffic are particularly important in switched environments where protocols such as DHCP/BOOTP, STP , LLDP and ARP need to be closely managed. SFlow also provides visibility into networked storage, including Ethernet SAN technologies (e.g. FCoE or AoE), that Typica Lly
