Description
This article will explain the
storm-control support on QFX5K with the SP (Service Provider) style interface configuration. It also applies to the EVPN/VxLAN use case.
Symptoms
There will be unexpected behaviours like non-working storm-control or storm-control working on different parameters when the below-mentioned guidelines are not followed with the SP (Service Provider) style interface configuration.
Solution
Storm control is supported only on a single IFL in SP style interface.
It applied to the whole IFD when applied to any IFL due to Hardware limitations.
When the storm is seen on the configured IFD, the log of the single IFL where this "storm-control" is configured will be seen, but this storm can be triggered by any IFL under this IFD.
Caution:
It is not supported when storm control is configured on multiple IFLs of SP style IFD.
Example Config:
=================================================================================
set interfaces xe-0/0/0 flexible-vlan-tagging
set interfaces xe-0/0/0 encapsulation extended-vlan-bridge
set interfaces xe-0/0/0 unit 500 vlan-id 500

set interfaces xe-0/0/0 unit 600 vlan-id 600
set interfaces xe-0/0/0 unit 700 vlan-id 700
!
set vlans vlan_500 interface xe-0/0/2.500
set vlans vlan_600 interface xe-0/0/2.600
set vlans vlan_700 interface xe-0/0/2.700
!
set forwarding-options storm-control-profiles STORM-10M-SHUTDOWN all bandwidth-level 10000
set forwarding-options storm-control-profiles STORM-10M-SHUTDOWN action-shutdown
Note:
This storm control profile can be applied to any single IFL.
