**STORM CONTROL**

Overview

1. We suggest you to apply storm-control on edge port on access switch and Don't apply storm-control on uplink port.

2. If access switch doesn't support storm-control , we suggest you to apply storm-control on distribution switch.

3. The limitation of 100 pps to 300 pps for unknown unicast/broadcast/multicast packets is proper.

 

**I. Configuration Steps**

To configure storm control on a port with keyword level, perform this task:

Ruijie>enable

Ruijie#configure termina

Ruijie(config)#interface gigabitEthernet 0/1  

Ruijie(config-if-GigabitEthernet 0/1)#**storm-control broadcast level 1**    ------>storm-control limits the number of broadcast packets to 1% of the bandwidth that is 1G*1%=10M

Ruijie(config-if-GigabitEthernet 0/1)#**storm-control unicast level 1**         ------>storm-control limites the number of unknown unicast packets to 1% of the bandwidth that is 1G*1% =10M

Ruijie(config-if-GigabitEthernet 0/1)#**storm-control multicast level 1**    

 

To configure storm control on a port with keyword pps, perform this task:

Ruijie>enable

Ruijie#configure termina

Ruijie(config)#interface gigabitEthernet 0/1  

Ruijie(config-if-GigabitEthernet 0/1)#**storm-control broadcast pps 3000**    ------>storm-control limits the number of broadcast packets to 200 packets per seconds

Ruijie(config-if-GigabitEthernet 0/1)#**storm-control unicast pps 200**      ------>storm-control limits the number of unknown unicast packets to 200 packets per seconds

Ruijie(config-if-GigabitEthernet 0/1)#**storm-control multicast 200**

Ruijie(config-if-GigabitEthernet 0/1)#end

 

**II. Verification**

Ruijie#**show storm-control**
