Configuring Virtual Servers
to a particular virtual server by using the VIP connection watermarks feature. With this feature, you may
set limits on each virtual server, allowing a fair distribution of connection resources among all virtual
servers.
You can configure a single virtual server to operate at either Level 4 or Level 7. To configure a virtual
Note
server to operate at Level 4, specify the server farm (default policy) as part of the virtual server
configuration. (See Step 3 in the following task table.) To configure a virtual server to operate at Level 7,
add SLB policies in the configuration of the virtual server. (See Step 7 in the following task table.)
The CSM can load-balance traffic from any IP protocol. When you configure a virtual server in virtual
server submode, you must define the IP protocol that the virtual server will accept.
Although all IP protocols have a protocol number, the CSM allows you to specify TCP or UDP by name
Note
instead of requiring you to enter their numbers.
Configure the virtual server in the virtual server configuration submode.
To configure virtual servers, perform this task:

Chapter 6 Configuring Virtual Servers, Maps, and Policies
Purpose
Restricts access to virtual servers to a specific owner
object.
Identifies the virtual server and enters the virtual
server configuration mode
Sets the owner object name for this virtual server.
Sets the IP address for the virtual server optional port
number or name and the connection coupling and
2
type . The protocol value is tcp, udp, Any (no port
number is required), or a number value (no port
number is required).
Associates the default server farm with the virtual
2 3
server . Only one server farm is allowed. If the server
farm is not specified, all the requests not matching any
other policies will be discarded.
(Optional) Configures connections from the client to
2 3
use the same real server
(Optional) Ensures that the CSM changes connections
in the appropriate direction back to the same source.
(Optional) Restricts which clients are allowed to use
2 3
the virtual server .
(Optional) Associates one or more content switching
policies with a virtual server

. The default is sticky off.
