General Policy Group (Networking)
The General policy group contains the following policies for networking. You can modify policy parameter values by double-clicking a policy to display the Setting Properties dialog.
Specifies which IP address family should be requested first in cases where DNS resolution is performed directly. The default is to ask for IPv4 A-type records and then IPv6 AAAA-type records. Enter the value as a comma delimited string.
Default: ipv4,ipv6
Defines the order of name lookups using the primary routes of DNS and NETBIOS. Enter the value as a comma delimited string.
Note: This parameter is not currently used.
Default: dns,netbios
When resolving addresses, this centrally managed parameter specifies what precedence should be applied to each address family. The default is to order IPv4 addresses before IPv6 addresses to maintain maximum interoperability. Enter the value as a comma delimited string.
Note: In a network where the majority of computers can only be reached by ipv6, it is recommended that the value be changed to ipv6,ipv4.
Default: ipv4,ipv6
Specifies the maximum number of buffers that will be stored in the dispatch pool. The dispatch pool is used to reduce the overhead of dynamic memory allocations when transmitting data over the network. Setting this value to a larger count may reduce CPU usage marginally at the expense of increased memory usage.
Default: 64
Specifies the maximum size in bytes of each buffer in the dispatch pool. The dispatch pool is used to reduce the overhead of dynamic memory allocations when transmitting data over the network. Setting this value to a larger size may reduce CPU usage marginally at the expense of increased memory usage.
Default: 8192
Controls whether end nodes should return IPv4 addresses from the lower-level name resolution functions. This parameter is only a placeholder in the current version of the software, and therefore end nodes will ignore the setting and always support IPv4 resolution.
Default: True
Controls whether end nodes should return IPv6 addresses from the lower-level name resolutions functions. The default is True, allowing IPv6 addresses to be returned. If disabled (False), the resolver removes any IPv6 addresses from the name resolution results.
Note: This parameter is honored by end nodes, as opposed to the mirror IPv4 control.
Default: True
Specifies the time in seconds between sending keep-alive messages. Keep-alive messages are sent when the network connection is idle to prevent automatic disconnection.
Default: 60
Specifies the maximum number of concurrent connections pending encryption negotiation in order to guard against “Denial of Service” attacks.
Default: 8
Specifies the maximum time in seconds within which a new connection must complete encryption negotiation. If encryption negotiation does not complete in the allotted time, the connection is refused. This setting is used in conjunction with the Maximum pending connections policy to guard against “Denial of Service” attacks.
Default: 10
Indicates whether periodic stream flushing is enabled. Periodic stream flushing reduces the bandwidth usage slightly at the expense of increased connection latency. If the connection speed is limited, enabling this setting may improve performance.
Default: False
Specifies the maximum number of buffers that will be stored in the receive pool. The receive pool is used to reduce the overhead of dynamic memory allocations when receiving data from the network. Setting this value to a larger count may reduce CPU usage marginally at the expense of increased memory usage.
Default: 50
Specifies the maximum size in bytes of each buffer in the receive pool. The receive pool is used to reduce the overhead of dynamic memory allocations when receiving data from the network. Setting this value to a larger size may reduce CPU usage marginally at the expense of increased memory usage.
Default: 8192
Controls which databases should be used when live name to address resolution fails. By default, if an address cannot be resolved through the primary routes of DNS (or NETBIOS), then certain infrastructure nodes will try to query the name to address lookup through a manager's MDB database or a server's database. The default fallback option should be left as is in most cases and only changed if requested by CA technical support personnel.
Valid values are as follows:
Default: 1
Indicates whether NETBIOS short names are used as a fallback if the fully-qualified name (FQN) lookup fails.
Default: True
Indicates whether host short names are used as a fallback if the fully-qualified name (FQN) lookup fails. If this policy is set to True, the domain portion of the FQN is stripped and lookup is attempted by the host name only. This is useful in situations where DNS resolution is not reliable and use of WINS/NETBIOS resolution can be useful.
Default: True
