4 VLAN Networks and NetFlow IEEE 802.1Q also known as VLAN tagging. Multiple bridged networks share the same physical link. Default NetFlow record doesn t contain VLAN tag field. We need to add VLAN tag information to the flow record. Physical Line VLAN 1203 VLAN 1202 VLAN 1201 (4B1h) Ethernet Frame 00:0C:29:11:79:C3 Destination MAC 00:0C:29:62:C7:EC Source MAC B Q Header C0 A Src IP C0 A Dst IP Payload NetFlow Record extended with VLAN field Duration TCP :2545 Proto Src IP : Port :80 Dst IP : Port.A.R.. Flags 9240 Packets 220 Bytes 1201 VLAN Krmíček, Čeleda, Novotný NfSen Plugin Supporting The Virtual Network Monitoring 4 / 24
5 NetFlow VLAN Support in FEDERICA Project NetFlow VLAN Issues NetFlow version 5 doesn t support VLAN tags. NetFlow version 9 defines VLAN tags (see RFC 3954). Routers and probes doesn t support VLAN export. NetFlow collectors doesn t support VLAN handling. Proposed Solution Dedicated FlowMon probes with VLAN support. We have added VLAN tag information as DST_AS field. Flow start Duration Proto Src IP Addr:Port Dst IP Addr:Port Packets Bytes Intf VLAN 06:49: ICMP :0 -> : M :49: ICMP :0 -> : M :51: ICMP :0 -> : M :51: ICMP :0 -> : M :51: ICMP :0 -> : M :51: ICMP :0 -> : M VLAN tag information is crucial for virtual circuits monitoring!
