Hello,
I am currently working on 6360-P48H switches and would appreciate some advice on the settings to use to prevent broadcast and non-unicast storms.
Please note that I do not know in advance the auto-negotiation speed of the user ports.
For the moment, I have applied the following configuration, but I am not entirely confident about its effectiveness:
interfaces 1/1/1-48 flood-limit bcast rate cap% 5 low-threshold 3
interfaces 1/1/1-48 flood-limit uucast rate cap% 10
I look forward to your expert advice.
laetitia.
Are you asking is that a valid configuration? Absolutely!
Are you asking will that address the problem you are trying to solve? No one will be able to say without any context. Maybe what you need is IPMS instead?
Again, what’s the origin for the ‘need’ for these commands?
In fact, we are currently in the process of setting up a new network infrastructure, and the client has asked us to implement protection mechanisms against broadcast or unknown unicast storms.
I have already implemented the following:
- The equivalent of Spanning Tree PortFast (spantree cist port 1/1/1-48 admin-edge enable)
- Loopback detection :
loopback-detection enable;
loopback-detection port 1/1/1-48 enable)
- BPDU filtering :
qos user-port filter bpdu user-port shutdown bpdu
policy port group UserPorts 1/1/1-48
qos apply
So I saw in the documentation that you can fine-tune settings at the port level, but maybe that isn’t necessary?
