Overview of System features Setup Wizard Cluster Management (Cluster Failover) Use this page to specify information for a failover appliance. Table 304 Option definitions Option Definition Address to use for load balancing Specifies the appliance address. Provides a list of all subnets assigned to the appliance. Cluster identifier If you have more than one cluster or McAfee Content Security Blade Server on the same subnet, assign each a different Cluster identifier to ensure the clusters do not conflict. The allowable range is 0-255. Enable scanning on this appliance (Not applicable on Content Security Blade Servers) If not selected, this appliance distributes all scanning workload to the scanning appliances. For a cluster of appliances, if you have only a master and a failover appliance, with both configured to scan traffic, the master will send most connections to the failover appliance for scanning. DNS and Routing Use this page within the Custom Setup Wizard to configure the appliance's use of DNS and routes. Domain Name System (DNS) servers translate or "map" the names of network devices into IP addresses (and the reverse operation). The appliance sends requests to DNS servers in the order that they are listed here. Table 305 Option definitions - DNS Servers Option Server Address Definition Displays the IP addresses of the DNS servers. The first server in the list must be your fastest or most reliable server. If the first server cannot resolve the request, the appliance contacts the second server. If no servers in the list can resolve the request, the appliance forwards the request to the DNS root name servers on the Internet. If your firewall prevents DNS lookup (typically on port 53), specify the IP address of a local device that provides name resolution New Server/ Delete Adds a new server to the list, or removes one when, for example, when you need to Selected Servers decommission a server due to network changes. Only send queries to these servers Selected by default. McAfee recommends that you leave this option selected because it might speed up DNS queries as the appliance sends the queries to the specified DNS servers only. If they don't know the address, they go to the root DNS servers on the Internet. When they get a reply, the appliance receives it and caches the response so that other servers that query that DNS server can get an answer more quickly. If you deselect this option, the appliance first tries to resolve the requests, or might query DNS servers outside your network. Table 306 Option definitions - Routing Option Network Address Mask Gateway Definition Type the network address of the route. Specifies how many hosts are on your network, for example, 255.255.255.0. Specifies the IP address of the router used as the next hop out of the network. The address 0.0.0.0 (IPv4), or :: (IPv6) means that the router has no default gateway.
