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.

Note A single virtual server can be configured to operate at either Level 4 or Level 7. For a virtual 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). 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	Purpose
Step 1
	Router(config)# ip slb vserver	Identify the virtual server and enter the virtual server
	virtserver-name	configuration mode1, 2.
Step 2
	Router(config-slb-vserver)# virtual	Set the IP address for the virtual server optional port
	ip-address tcp port	number or name and the connection coupling and
		type2.
Step 3
	Router(config-slb-vserver)# serverfarm	Note	Before you can associate a server farm with the
	serverfarm-name		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
		server2. 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.
Step 4
	Router(config-slb-vserver)# sticky	(Optional) Configure connections from the client to
	duration	use the same real server2. The default is sticky on.
Step 5	Router(config-slb-vserver)# client	(Optional) Restrict which clients are allowed to use the
	ip-address network-mask [exclude]	virtual server2.
Step 6	Router(config-slb-vserver)# slb-policy	(Optional) Associate content switching policies with a
	policy-name	virtual server2. Policies are processed in the order in
		which they are entered in the virtual server
		configuration. See the “Configuring Policies” section
		on page 26.
Step 7	Router(config-slb-vserver)# inservice	Enable the virtual server for use by the CSM2.
Step 8	Router# show ip slb vserver [details]	Display information for virtual servers defined for
		Content Switching.

1.Enter the exit command to leave a mode or submode. Enter the end command to return to the menu’s top level.

2.The no form of this command restores the defaults.
