IMPORTANT:
Only the source IP address/wildcard, destination IP address/wildcard, protocol type,
source port number, destination port number, and VPN instance match criteria are
effective to a virtual service.
Priority
Priority of a virtual server. A higher value represents a higher priority. A virtual service
with a higher priority will be matched first.
Persistence Method
Select a method for associating links with connections that access the same virtual
service.
Using a persistence method can reduce times that an LB device distributes traffic and
services.
• If you do not select a persistence method, no links or connections will be
associated.
• Source IP—Connections that have the same source address will be associated with
the same link.
• Destination IP—Connections that have the same destination address will be
associated with the same link.
• Source Port—Connections that have the same source port will be associated with
the same link.
• Destination Port—Connections that have the same destination port will be
associated with the same link.
• Source IP + Port—Connections that have the same source address and port will be
associated with the same link.
• Destination IP + Port—Connections that have the same destination address and
port will be associated with the same link.
Persistence Timeout
Set the aging time of a persistence entry.
When a persistence method is configured, persistence entries are generated
according to the persistence method. If a persistence entry is not matched within the
persistence timeout time, the persistence entry is aged out.
This option cannot be set if you do not select a persistence method.
Connection Limit Maximum number of concurrent connections of a virtual service.
Logical Link Group Logical link group referenced by a virtual service.
