Table 20 Configuration items
Item Description
Virtual Device ID Enter a VD ID that is globally unique.
Virtual Device
Name
Enter a VD name that is globally unique.
Max. Sessions
Set the maximum number of concurrent sessions that can be established on the VD.
Limiting the maximum number of concurrent sessions helps protect the device against
potential attacks, such as SYN flood attacks.
Max. LB Real
Service Groups Set the maximum number of real service groups for load balancing, including IPv4 and
IPv6 real service groups for server load balancing.
Max. LB Real
Services Set the maximum number of real services for load balancing, including IPv4 real
services and IPv6 real services for load balancing.
Max. LB Virtual
Services Set the maximum number of virtual services for load balancing, including IPv4 virtual
services and IPv6 virtual services for load balancing.
On the VD list page, you can click the Max. Sessions link, the Max. LB Real Service Groups link, the Max.
LB Real Services link, or the Max. LB Virtual Services link of a VD (except the root VD) to modify its value.
The sum of the Max. Sessions of all VDs is the maximum number of sessions supported by the physical
device. The maximum number of sessions of the root VD is the remaining number of sessions of the
physical device. This rule also applies to the Max. LB Real Service Groups, the Max. LB Real Services,
and the Max. LB Virtual Services.
When you change the value of the Max. LB Real Service Groups, the Max. LB Real Services, or the Max.
LB Virtual Services, the target value must be larger than the number of existing real service groups for
load balancing, the number of existing real services for load balancing, or the number of virtual services
for load balancing.
For more information about the load balancing feature, see Load Balancing Configuration Guide.
