# oz0 node block

> Block nodes: every edge that reaches management refuses their next call on every port within 2 seconds, and ends their control streams.

For: Operators and developers looking up a command.

Block nodes: every edge that reaches management refuses their next call on every port within 2 seconds,
and ends their control streams. The command waits for the edges to apply the block (--wait) and says where it
applied, as in "Block applied on 2 of 3 edges; edge-c behind for 40 s".

## Usage

```bash
oz0 node block <node-id>... [flags]
```
