Field Description
Name Either accept the automatically incremented value in this field, or enter a
unique name for this server. Valid entries are unquoted text strings with no
spaces and a maximum of 64 characters.
Type Select the type of server:
• Host—Indicates that this is a typical real server that provides content
and services to clients.
• Redirect—Indicates that this server is used to redirect traffic to a new
location.
State Select the state of this real server:
• In Service—The real server is in service.
• Out Of Service—The real server is out of service.

alphanumeric text strings with no spaces and a maximum of 240 characters.
IP Address Type These selections appear for only real servers specified as hosts.
Select the IP address type of this real server:
• IPv6—The real server has an IPv6 address.
• IPv4—The real server has an IPv4 address.
IPv6/IPv4 Address This field appears for only real servers specified as hosts.
Enter a unique IP address as indicated by the IP Address Type field. The IP
address cannot be of an existing virtual IP address (VIP), real server or
interface in the context.
Fail-On-All This field appears only for real servers identified as host servers.
By default, real servers with multiple probes configured for them have an
OR logic associated with them. This means that if one of the real server
probes fails, the real server fails and enters the PROBE-FAILED state.
Click this check box to configure a real server to remain in the
OPERATIONAL state unless all probes associated with it fail (AND logic).
The Fail-On-All function is applicable to all probe types.
Min. Connections Enter the minimum number of connections to be allowed on this server
before the ACE appliance starts sending connections again after it has
exceeded the Max. Connections limit. This value must be less than or equal
to the Max. Connections value. By default, this value is equal to the Max.
Connections value. Valid entries are integers from 1 to 4000000.
Max. Connections Enter the maximum number of active connections allowed on this server.
When the number of connections exceeds this value, the ACE appliance
stops sending connections to this server until the number of connections falls
below the Min. Connections value. Valid entries are integers from 1 to
4000000, and the default is 4000000.
