B. Choose Active/Active mode if you have special network conditions; particularly if you have
two networks where routing may not exist. If network security is important and if you are
using proxy-type deployments, you also should choose this mode.
Figure 153 Active/Active Network
In this mode, CC-SG acts as a “router” or “traffic cop” between two separate IP domains;
particularly when Proxy mode is being used. (Please refer to Connection Mode, later in this
chapter, for additional information). In Proxy mode, Active/Active mode is required so CC-
SG routes proxied PC client sessions to their respective nodes. It is recommended that
Raritan-controlled devices be connected to LAN1 while proxied PC client connections are
connected to LAN2. Both NICs should be on separate sub-networks
⎯however, if you are
using DHCP, this may not be possible and therefore it would not be a supported configuration.
While configuring both NICs, specify a default gateway address for only one NIC and leave
the other blank.
When a NIC fails, CC-SG attempts to route the packet from the other NIC based on the
current IP routing table. This routing may not be successful, especially if firewalls are
involved. If additional routes are needed, they can be added in Diagnostic Console. Please
refer to Editing Static Routes (Network Interfaces), later in this chapter, for additional
information.
Note: Clustering cannot be configured when using Active/Active mode.
5. Click the Configuration drop-down arrow and select either DHCP or Static from the list. If
you choose DHCP, make sure your DHCP server has been configured correctly, and then
type a hostname. The DNS information, the domain suffix, IP address, default gateway and
subnet mask, will be automatically populated once Update Configuration is selected. With
this information, CC-SG registers itself dynamically with the DNS server if it accepts
dynamic updates. After a successful registration, CC-SG can be accessed via the hostname
since the IP address may not be known when using DHCP.
If you choose Static, type an IP address, subnet mask, default gateway, Primary DNS and
Secondary DNS information in the appropriate fields. Also, type a string for your domain
setup in domain suffix.
6. Click the Adapter Speed drop-down arrow and select a line speed from the list.
7. 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,
available, click the Adapter Mode drop-down arrow and select a duplex mode from the list.
