Hi team!
I test broadcast/multicast/unknown-unicast limits on ICX7250 and ICX7150 (hw ver. 8.0.9).
I've configured ports as:
    interface ethernet 1/1/1
     spanning-tree 802-1w admin-edge-port
     broadcast limit 96 kbps
     multicast limit 400 kbps
     unknown-unicast limit 96 kbps
     stp-bpdu-guard
But, nothing happens! I genarate broadcast traffic, but port works normally in this moment.
Can anyone come across this problem?

Hello Nik kul,

Is this a standalone, stack or SPX environment ? BUM rate limiting is not supported on PE ports in an SPX environment but do support on CB ports.

Do u see the configured values under show rate-limit broadcast/multicast/unknown-unicast output ?

Hi Jijo,

I tested on stack of two ICX7250 and standalone ICX7150.
What's mean PE and CB ports?

Output from console:
   7250#show rate-limit broadcast 
   Broadcast Limit Settings:
   Port               Limit   Packets/Kbps
   1/1/1                 96           Kbps
   1/1/2                 96           Kbps
   1/1/3                 96           Kbps
   2/1/1                 96           Kbps
   2/1/2                 96           Kbps

Hi Nik Kul,

Thanks , PE and CB are terminologies in campus fabric, reference link below.

http://docs.ruckuswireless.com/fastiron/08.0.60/fastiron-08060-switchstackingguide/GUID-B2FA4C26-4F2F-4AA8-AF69-2379202BBE6D.html

It seems the config is applied correctly, would you be able to open a tac case for debugging your environment ? There are some shell commands to check if the HW registers are correctly set and need remote access.

Unfortunately, I can't open tac case.
This equipment was got from provider for testing by short period. It doesn't have support licenses.

Hello Nik kul,

Understood, The commands are bit complex and not straightforward.
Could you also test the same on 08.0.70e code ?
