Specifying Rule VLAN Matches (NSM Procedure)
If you deploy an IDP Series device in a virtual local area network (VLAN), you can configure rules that require a match of VLAN tag. Table 1 describes VLAN tag settings.
To modify VLAN match settings:
- In the NSM navigation tree, select Policy Manager > Security Policies.
- Select the security policy you want to edit.
- In the security policy pane, click the IDP tab to display the IDP rulebase table.
- Modify VLAN match settings by right-clicking the table cell for the setting and making your selection.
- Click OK to save your changes.
