### Blacklist Source and Destination Ports
By default, the network experiments disrupt traffic for all the source and destination ports. The specific ports can be blacklisted via `SOURCE_PORTS` and `DESTINATION_PORTS` ENV.
- `SOURCE_PORTS`: Provide the comma separated source ports preceded by `!`, that you'd like to blacklist from the chaos.
- `DESTINATION_PORTS`: Provide the comma separated destination ports preceded by `!` , that you'd like to blacklist from the chaos.
Use the following example to tune this:
[embedmd]:# (pod-network-corruption/blacklist-source-and-destination-ports.yaml yaml)
```yaml
# blacklist the source and destination ports
apiVersion: litmuschaos.io/v1alpha1
kind: ChaosEngine
metadata:
name: engine-nginx
spec:
engineState: "active"
annotationCheck: "false"
appinfo:
appns: "default"
applabel: "app=nginx"
appkind: "deployment"
chaosServiceAccount: pod-network-corruption-sa
experiments:
- name: pod-network-corruption
spec:
components:
env:
# it will blacklist 80 and 8080 source ports
- name: SOURCE_PORTS
value: '!80,8080'
# it will blacklist 8080 and 9000 destination ports
- name: DESTINATION_PORTS
value: '!8080,9000'
- name: TOTAL_CHAOS_DURATION
value: '60'
```
### Network Interface
The defined name of the ethernet interface, which is considered for shaping traffic. It can be tuned via `NETWORK_INTERFACE` ENV. Its default value is `eth0`.
