4.3.2.7 sFlow
Agent
The sFlow Agent Summary page shows information about the sFlow agent on the
device. sFlow is an industry standard technology for monitoring high-speed switched
and routed networks. The sFlow agent can monitor network traffic on each port and
generate sFlow data to send to a centralized sFlow receiver (also known as a collec-
tor).
To access this page, click System > Advanced Configuration > sFlow > Agent.

The following table describes the items in the previous figure.
Receiver
Use the sFlow Receiver Configuration page to view and to edit the sFlow receiver

TCP Fragment Enable this option to allow the device to drop packets that have a TCP
payload where the IP payload length minus the IP header size is less
than the minimum allowed TCP header size.
TCP Offset Enable this option to allow the device to drop packets that have a TCP
header Offset set to 1.
Min TCP Hdr Size The minimum TCP header size allowed. If First Fragment DoS pre-
vention is enabled, the device will drop packets that have a TCP
header smaller than this configured value.
ICMP Settings
ICMP Enable this option to allow the device to drop ICMP packets that have
a type set to ECHO_REQ (ping) and a payload size greater than the
ICMP payload size configured in the Max ICMPv4 Size field.
Max ICMPv4 Size The maximum allowed ICMPv4 packet size. If ICMP DoS prevention
is enabled, the device will drop ICMPv4 ping packets that have a size
greater then this configured maximum ICMPv4 packet size.
ICMPv6 Enable this option to allow the device to drop ICMP packets that have
a type set to ECHO_REQ (ping) and a payload size greater than the
ICMP payload size configured in the Max ICMPv6 Size field.
Max ICMPv6 Size The maximum allowed IPv6 ICMP packet size. If ICMP DoS preven-
tion is enabled, the switch will drop IPv6 ICMP ping packets that have
a size greater than this configured maximum ICMPv6 packet size.
ICMP Fragment Enable this option to allow the device to drop fragmented ICMP pack-
ets.
