    11  ### Examples
    12  
    13  ```
    14    # Isolate all pods network under the default namespace from the outside world, including the k8s internal network.
    15    kbcli fault network partition
    16    
    17    # The specified pod is isolated from the k8s external network "kubeblocks.io".
    18    kbcli fault network partition mycluster-mysql-1 --external-targets=kubeblocks.io
    19    
    20    # Isolate the network between two pods.
    21    kbcli fault network partition mycluster-mysql-1 --target-label=statefulset.kubernetes.io/pod-name=mycluster-mysql-2
    22    
    23    // Like the partition command, the target can be specified through --target-label or --external-targets. The pod only has obstacles in communicating with this target. If the target is not specified, all communication will be blocked.
    24    # Block all pod communication under the default namespace, resulting in a 50% packet loss rate.
    25    kbcli fault network loss --loss=50
    26    
    27    # Block the specified pod communication, so that the packet loss rate is 50%.
    28    kbcli fault network loss mysql-cluster-mysql-2 --loss=50
    29    
    30    kbcli fault network corrupt --corrupt=50
    31    
    32    # Blocks specified pod communication with a 50% packet corruption rate.
    33    kbcli fault network corrupt mysql-cluster-mysql-2 --corrupt=50
    34    
    35    kbcli fault network duplicate --duplicate=50
    36    
    37    # Block specified pod communication so that the packet repetition rate is 50%.
    38    kbcli fault network duplicate mysql-cluster-mysql-2 --duplicate=50
    39    
    40    kbcli fault network delay --latency=10s
    41    
    42    # Block the communication of the specified pod, causing its network delay for 10s.
    43    kbcli fault network delay mysql-cluster-mysql-2 --latency=10s
    44    
    45    # Limit the communication bandwidth between mysql-cluster-mysql-2 and the outside.
    46    kbcli fault network bandwidth mysql-cluster-mysql-2 --rate=1kbps --duration=1m
