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

Description
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.
Enable this option to allow the device to drop packets that have a TCP
header Offset set to 1.
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.
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.
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.
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.
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.
Enable this option to allow the device to drop fragmented ICMP pack-
ets.
