Usage Guidelines
• The statistics show the cumulative totals since the last time the switch was powered on or since the last
reset of the switch was executed.
• Packets received on a port that is a member of the UserPorts group are dropped if they contain a source
IP network address that does not match the IP subnet for the port. This is done to block spoofed IP traf-
fic. If the UserPorts group function is active and spoofed traffic was detected and blocked, the output
display of this command will include statistics regarding the spoofed traffic.
fic. If the UserPorts group function is active and spoofed traffic was detected and blocked, the output
display of this command will include statistics regarding the spoofed traffic.
• Note that the presence of spoofing event statistics in the output display of this command indicates that
an attack was prevented, not that the switch is currently under attack.
• If statistics for spoofed traffic are not displayed, then a spoofing attempt has not occurred since the last
time this command was issued.
