Configuring the Content Switching Module

Configuring Virtual Servers

Virtual servers represent groups of real servers and are associated with real server farms through
policies. Configuring virtual servers requires setting the attributes of the virtual server specifying the
default server farm (default policy) and eventually associating other server farms through a list of
policies.
A single virtual server can be configured to operate at either Level 4 or Level 7. For a virtual server
Note
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). For 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).
Configure the virtual server in the virtual server configuration submode.
To configure virtual servers, perform this task:
Command
Step 1
Router(config)# ip slb vserver
virtserver-name
Step 2
Router(config-slb-vserver)# virtual
ip-address tcp port
Step 3
Router(config-slb-vserver)# serverfarm
serverfarm-name
Step 4
Router(config-slb-vserver)# sticky
duration
Step 5
Router(config-slb-vserver)# client
ip-address network-mask [exclude]
Step 6
Router(config-slb-vserver)# slb-policy
policy-name
Step 7
Router(config-slb-vserver)# inservice
Step 8
Router# show ip slb vserver [details]

1, 2
configuration mode .
Set the IP address for the virtual server optional port
number or name and the connection coupling and
2
type .
Before you can associate a server farm with the
Note
virtual server, you must configure the server
farm. See the "Configuring Server Farms"
section on page 24.
Associate the default server farm with the virtual
2
server . The default server farm (default policy) is used
if a request does not match any slb policy or if there are
no policies associated with the virtual server.
(Optional) Configure connections from the client to
2
use the same real server . The default is sticky on.
(Optional) Restrict which clients are allowed to use the
2
virtual server .
(Optional) Associate content switching policies with a
2
virtual server . Policies are processed in the order in
which they are entered in the virtual server
configuration. See the "Configuring Policies" section
on page 26.
