Item Description
Port
Set a port number that is related to the following parameters:
• Health monitoring method for a real service group—If this parameter is
0, the port number of the real service is used for heath monitoring
(except RADIUS and SIP health monitoring). For TCP and UDPNORMAL
health monitoring, if both this parameter and the port number of the real
service are 0, the health monitoring fails.
• Forwarding mode for a virtual service—If the forwarding mode is set to
NAT, the port number is taken as the destination port of a packet after
NAT translation, and the port number must be consistent with that of the
server; if the forwarding mode is set to direct routing or firewall
forwarding, the port number is used only for health monitoring.
Weight
Set the weight to be used in the weighted round robin and weighted least
connections algorithms.
A smaller weight indicates that the real service is less scheduled.
Priority
Specify the priority of the real service when the real service group adopts
the local priority scheduling algorithm. The larger the value, the greater the
priority.
Connection Limit Set the maximum number of concurrent connections of the real service.
Real Service Group Specify the real service group to which the real service belongs.
ACL
ACL specified for a real service. To configure ACL rules, select Security >
ACL.

Configuration
Health
Monitoring
Method
Select one of the following health monitoring methods:
• No Monitoring
• Same As Real Service Group
• Specified—Use the health monitoring method specified by the real
service to perform health monitoring. If you select this option, you must
specify a health monitoring method for the real service (add one or
more items in the Available Health Monitoring Methods field to the
Selected Health Monitoring Methods field), and specify the health
monitoring success criteria.
Health
Monitoring
Success
Criteria
When you select Specified for Health Monitoring Method, you must specify
the health monitoring success criteria.
• If you select All, health monitoring succeeds only when all the selected
health monitoring methods succeed.
• If you select At Least and specify a value, health monitoring succeeds
when the number of succeeded health monitoring methods reaches the
specified value.
Stopping service or enabling slow-offline
To remove the server or network device corresponding to a real service from a cluster, or temporarily stop
a real service, you can stop the service or enable slow-offline:
• If you stop the service, the LB product does not assign any traffic to the real service.
• If you enable slow-offline, the real service continues to process the traffic previously assigned to it,
but the LB product does not assign any new service to the real service. Remove the server or network
device from the cluster after the original services are processed to avoid service interruption.
