Chapter 65 Managing Cisco Catalyst Switches and Cisco 7600 Series Routers
VLANs
Step 8 (Optional) For a Layer 3 VLAN, define a switched virtual interface (SVI):
a. To make the SVI active, select the Enable Interface check box. An SVI enables routing between
VLANs and provides IP host connectivity to the switch. If you do not select this check box, the SVI
is created in shutdown mode.
b. Enter the IP address for the SVI.
c. Enter the SVI subnet mask by typing it, or select a netmask value from the Subnet Mask list.
d. Enter an optional description, if required.
Step 9 Do one or both of the following:
• To associate access ports with the VLAN, enter their names in the Access Ports text box or click
Select to open an interface selector.
• To associate trunk ports with the VLAN, enter their names in the Trunk Ports text box or click Select
to open an interface selector.
See Interface Selector Dialog Box—VLAN ACL Content, page 65-43 for a description of the fields in
the dialog box. For more information about defining ports, see Creating or Editing Ports on Cisco
Catalyst Switches and Cisco 7600 Series Routers, page 65-5.
Step 10 Click OK to save your definitions locally on the client and close the dialog box.
Deleting VLANs
You can delete a VLAN. However, deleting a VLAN does not delete it from any policy that might
reference it. Ensure that your other policies do not use the VLAN before you delete it. When you submit
your changes to the database, Security Manager points out any undefined VLANs that are referenced by
other policies.
