Deactivating rules

You can deactivate rules that enable cross-VLAN routing in the Trusted Firewall feature.

Because the rules are deactivated in the Virtual I/O Server > (VIOS ) interface, additional information about the commands and process are available in the VIOS topic collection in the Power Systems Hardware Information Center.

To deactivate a rule, complete the following steps:

Open the VIOS command-line interface.
To display all active filter rules, enter the following command:
```
lsvfilt -a
```
You can omit the -a flag to display all of the filter rules stored in the Object Data Manager.
Note the identification number for the filter rule that you are deactivating. For this example, the identification number of the filter rule is 23.
Deactivate filter rule 23 when it is active in the kernel by entering the following command:
```
rmvfilt -n 23
```
To deactivate all of the filter rules in the kernel, enter the following command:
```
rmvfilt -n all
```
