Configure IP Isolation Mode with IPV4 or Dual Stack Mode with IPV6

• To configure IP Isolation mode in CC-SG:

1. Choose Administration > Configuration.
2. Click the Network Setup tab.
3. Type the CC-SG hostname in the Host name field. See Terminology/Acronyms for hostname rules. When you click Update Configuration to save the configuration, the Host name field will be updated to reflect the Fully-Qualified Domain Name (FQDN) if a DNS and domain suffix have been configured.
4. To use IPV4 only, complete only the IPV4 section, and make sure the IPV6 checkbox is not selected. To use dual stack mode, select the IPV6 checkbox, and complete both IPV4 and IPV6 sections. When you change between IPV4 and dual stack mode, CC-SG must reboot. You will be prompted to reboot now or later, and must enter password, broadcast message, and timing for reboot. Verify that you do not have any services depending on the mode you disable.
5. Select IP Isolation mode.
6. Configure the Primary LAN in the left column, and the Secondary LAN in the right column.
7. In the IPV4 configuration section, select DHCP or Static in the Configuration drop-down list.

   DHCP:

   • If you choose DHCP, the Primary DNS, Secondary DNS, Domain Suffix, IP address, Subnet mask, and Default gateway fields will be automatically populated (if your DHCP server is configured to provide this information), once you save this network setup and restart CC-SG.
   • With the information the DHCP server provides, CC-SG registers itself dynamically with the DNS server if it accepts dynamic updates.
   • See Recommended DHCP Configurations for CC-SG.

   Static:

   • If you choose Static, type Primary DNS, Secondary DNS, Domain Suffix, IP address, and Subnet mask in the appropriate fields.
   • Specify only one Default gateway, not both.
8. To run in dual stack mode, complete the IPV6 configuration section. Skip this step to use IPV4 only.
   1. Select the Enable IPV6 checkbox.
   2. Select Router Discovery or Static in the Configuration drop-down list.
9. If you choose Router Discovery, some fields are automatically populated: Global/Unique Local IPV6 Address, Prefix Length, Default Gateway IPV6 Address, and Link-Local IPV6 Address and Zone ID.
10. If you choose Static, enter the Global/Unique Local IPV6 Address, Prefix Length, and Default Gateway IPV6 Address.
11. Click the Adapter Speed drop-down arrow and select a line speed from the list. Make sure your selection agrees with your switch's adapter port setting. If your switch uses 1 Gig line speed, select Auto.
12. If you selected Auto in the Adapter Speed field, the Adapter Mode field is disabled, with Full Duplex selected automatically. If you specified an Adapter Speed other than Auto, click the Adapter Mode drop-down arrow and select a duplex mode from the list.
13. Click Update Configuration to save your changes. CC-SG reboots.
