UDP Health Check Parameters
The following tables describe the parameters for UDP health checks. For the hard-coded, out-of-the-box health check, the values are read-only. Unless stated otherwise, each Default in the following table is also the value in the hard-coded, out-of-the-box health check.
 
Health Check — UDP: General Parameters 
Parameter
Description
UDP ID
The identifier of the health check.
Maximum characters for version 31.0.6.0 and later, and version 32.1.0.0 and later: 128, for all other versions: 32
Description
The name for a user-defined health check.
Maximum characters for version 31.0.6.0 and later, and version 32.1.0.0 and later: 128, for all other versions: 32
Destination Port
The destination port.
Values:
*none — The value is taken from rport or the bound element.
*2 – 65,534
Default: none
IP Version
Specifies the type of IP address.
Values: IPv4, IPv6
Default: IPv4
Destination IP Address/Hostname
The destination IP address or hostname.
Default: none
Invert Result
Specifies whether to invert of expected result.
Values: Enabled, Disabled
Default: Disabled
Transparent Health Check
(This parameter is available only in version 30.1 and later)
Specifies whether the health check is performed in transparent mode. A transparent health check sends the request to the health check target via the monitored element (real server). Such health checks are recommended, for example, to test WAN Links servers. The destination address and port must always be specified for a transparent health check. A transparent health check cannot be attached directly to a group or server; it can only be part of a logical expression health check together with a health check that test the availability of the monitored element non-transparently.
Values: Enabled, Disabled
Default: Disabled
 
Health Check — UDP: UDP Parameters 
Parameter
Description
Padding to 64 Bytes
(This parameter is available only in version 30.5 and later)
Enables Alteon to send a UDP packet with no payload for health check purposes in cases where the server does not support a UDP payload.
Values: Enabled, Disabled
Default: Enabled
