Setting Unknown Unicast Storm Thresholds

You can protect your network from excess unknown unicast traffic by setting
thresholds for each port. Any multicast packets exceeding the specified threshold
will then be dropped.

(Range: 1-28 on iES4028F/iES4028FP, 1-24 on iES4024GP)
• Type – Indicates the port type. (1000BASE-T or 1000BASE-SFP)
• Protect Status – Enables or disables unknown unicast storm control.
(Default: Disabled)
• Threshold – Threshold as percentage of port bandwidth. (Range: 64-100000
kilobits per second for Fast Ethernet ports; 64-1000000 kilobits per second for
Gigabit ports; Default: 64 kilobits per second)
• Trunk – Shows if port is a trunk member.
Web – Click Configuration, Port, Port Unknown Unicast Control or Trunk Unknown
