# PacketFrequency

Config path: `checks.net.packetfrequency`\
Permission (bypass): `nocheatplus.checks.net.packetfrequency`\
Exemption: `NET_PACKETFREQUENCY`\
Depends on: `ProtocolLib (plugin)`

This check limits the overall amount of packets a player can send in one time-frame.

| Option         | Description                                                                            |
| -------------- | -------------------------------------------------------------------------------------- |
| limitpersecond | Maximum amount of packets that NCP will accept in one second                           |
| seconds        | Seconds that the check will use in its internals to determine how long it should last. |

{% hint style="danger" %}
As of MC 1.9, it shouldn't be possible to crash/harm servers by flodding them with packets, but if you notice further packet-based exploits in newer versions, then force-enabling this check might be useful.
{% endhint %}
