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
