Configuring Ethernet Interfaces
Configure VLAN Support
Figure 3-4. Routing VLAN Traffic Between Layer 2 Switches
If your company is using Layer 2 switches, you may want to enable VLAN
support on the ProCurve Secure Router and configure it to route the VLAN
traffic on your internal network.
You may also want to enable VLAN support on the ProCurve Secure Router
so that you can use VLANs to apply network access controls. By using VLANs,
you can tailor access controls for the users who are members of different
VLANs. For example, you can apply different access controls to the marketing
department, which is part of VLAN12, than the access controls you apply to
the executives of your company, which are part of VLAN 20. (For more
information about access controls on router interfaces, see the Advanced
Management and Configuration Guide, Chapter 5: Applying Access Control
to Router Interfaces.)
You can also use VLANs to grant groups of users access to VPNs. (For more
information about VPNs, see the Advanced Management and Configuration
Guide, Chapter 10: Virtual Private Networks.)
Configuring VLAN Support
Configuring VLAN support on the ProCurve Secure Router involves four steps:
1. Enable the ProCurve Secure Router to read IEEE 802.1Q tags.
2. Create Ethernet subinterfaces.
3. Associate each Ethernet subinterface with a VLAN ID.
4. Assign the Ethernet subinterfaces an IP address.
