Q1. How long is the interval and what number of hit is it?
ex. if it repeated x times in y mins, block for Z sec.

Q2. If someone was blocked for 30 seconds, does it show under block client list like below?

I couldn't find documents about it anywhere.

Please let me know about it.

Thanks in advance.

Hi Jeronimo,

If this capability is activated, any clients that repeatedly fail in attempting authentication will be temporarily blocked for a period of time (10~1200 seconds, default is 30). Clients temporarily blocked by the Intrusion Prevention feature are not added to the Blocked Clients list on the Services & Profiles > Access Control page, Blocked Clients section.

For repeated authentication failure blocking feature, if ZD detects station authentication failures more than 5 times, there will be an event log entry. If it is more than 10 times and if the temp block is enabled, this station will be blocked for 30 seconds. After the block is lifted, the counter is reset. Auth failure includes failed shared key auth failure, 802.1x/WPA auth failures.

This info is available in ZD User Guide and in Knowledgebase article

Hello Pradeep.

Thanks for prompt reply very much.

I didn't still have an answer about a interval form your reply.

But from a document, it seems that interval is 300sec.
