config traffic control
| latter of which will now provide shutdown, recovery and trap |
| notification functions for the Switch. |
Parameters | <portlist> − Used to specify a range of ports to be configured for |
| traffic control. This is specified by listing the lowest switch number |
| and the beginning port number on that switch, separated by a |
| colon. Then the highest switch number, and the highest port |
| number of the range (also separated by a colon) are specified. |
| The beginning and end of the port list range are separated by a |
| dash. For example, 1:3 specifies switch number 1, port 3. 2:4 |
| specifies switch number 2, port 4. |
| between switch 1, port 3 and switch 2, port 4 − in numerical order. |
| all − Specifies all ports are to be configured for traffic control on |
| the Switch. |
| broadcast [enabled disabled] − Enables or disables broadcast |
| storm control. |
| multicast [enabled disabled] − Enables or disables multicast |
| storm control. |
| dlf [enabled disabled] − Enables or disables dlf traffic control. |
| action – Used to configure the action taken when a storm control |
| has been detected on the Switch. The user has two options: |
| • drop - Utilizes the hardware Traffic Control mechanism, |
| which means the Switch’s hardware will determine the |
| Packet Storm based on the Threshold value stated and drop |
| packets until the issue is resolved. |
| • shutdown - Utilizes the Switch’s software Traffic Control |
| mechanism to determine the Packet Storm occurring. Once |
| detected, the port will deny all incoming traffic to the port |
| except STP BPDU packets, which are essential in keeping |
| the Spanning Tree operational on the Switch. If the |
| countdown timer has expired and yet the Packet Storm |
| continues, the port will be placed in Shutdown Forever mode |
| and is no longer operational until the user manually resets |
| the port using the config traffic control_recover command. |
| Choosing this option obligates the user to configure the |
| time_interval field as well, which will provide packet count |
| samplings from the Switch’s chip to determine if a Packet |
| Storm is occurring. |
| threshold <value |
| specified traffic control is switched on. The <value> is the number |
| of broadcast/multicast/dlf packets, in kilopackets per second |
| (Kpps), received by the Switch that will trigger the storm traffic |
| control measures. |
| countdown - The countdown timer is set to determine the amount |
| of time, in minutes, that the Switch will wait before shutting down |
| the port that is experiencing a traffic storm. This parameter is only |
| useful for ports configured as shutdown in the action field of this |
| command and therefore will not operate for Hardware based |
| Traffic Control implementations. |
| • value 0 - 0 is the default setting for this field and 0 will |
| denote that the port will never shutdown. |
| • value |
| Switch will wait before shutting down. Once this time expires |
