Setting Broadcast Storm Thresholds, 109 | SMC Networks SMC6224M

PORT CONFIGURATION

Setting Broadcast Storm Thresholds

Broadcast storms may occur when a device on your network is malfunctioning, or if application programs are not well designed or properly configured. If there is too much broadcast traffic on your network, performance can be severely degraded or everything can come to complete halt.

You can protect your network from broadcast storms by setting a threshold for broadcast traffic. Any broadcast packets exceeding the specified threshold will then be dropped.

Command Usage

•Broadcast Storm Control is enabled by default.

•Broadcast control does not effect IP multicast traffic.

•The specified threshold applies to all ports on the switch.

Command Attributes

•Port5 – Port number.

•Trunk6 – Trunk number.

•Type – Indicates the port type. (100BASE-TX, 1000BASE-T, or SFP)

•Threshold – Threshold as percentage of port bandwidth. (Range: 64-95232000 octets per second; Default: 32000)

•Protect Status – Shows whether or not broadcast storm control has been enabled. (Default: Enabled)

•Trunk5 – Shows if a port is a trunk member.
