Cisco Systems 6000 manual Configuring Client NAT Pools

Configuring the Content Switching Module

	Command	Purpose
Step 5
	Router(config-redirect-v)# idle duration	Set the CSM connection idle timer for the redirect
		virtual server2.
Step 6
	Router(config-redirect-v)# client	Configure the combination of the ip-addressand
	ip-address network-mask [exclude]	network-maskused to restrict which clients are
		allowed to access the redirect virtual server2.
Step 7
	Router(config-redirect-v)# inservice	Enable the redirect virtual server and begin
		advertisements2.
Step 8
	Router# show ip slb vserver redirect	Show all redirect servers configured.
	[detail]

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.

This example shows how to configure redirect virtual servers to specify virtual servers to real servers in a server farm:

Router (config)# ip slb serverfarm FARM1

Router (config-slb-sfarm)# redirect-vserver REDIR_1

Router (config-slb-redirect-)# webhost relocation relo 301

Router (config-slb-redirect-)# virtual 172.1.2.30 tcp www

Router (config-slb-redirect-)# inservice

Router (config-slb-redirect-)# exit

Router (config-slb-sfarm)# redirect-vserver REDIR_2

Router (config-slb-redirect-)# webhost relocation relo 301

Router (config-slb-redirect-)# virtual 172.1.2.31 tcp www

Router (config-slb-redirect-)# inservice

Router (config-slb-redirect-)# exit

Router (config-slb-sfarm)# real 10.8.0.8

Router (config-slb-real)# redirect-vserver REDIR_1

Router (config-slb-real)# inservice

Router (config-slb-sfarm)# real 10.8.0.9

Router (config-slb-real)# redirect-vserver REDIR_2

Router (config-slb-real)# inservice

Router (config-slb-real)# end

Router# show ip slb serverfarm detail

Configuring Client NAT Pools

When you configure client Network Address Translation (NAT) pools, NAT converts the source IP address of the client requests into an IP address on the server-side VLAN. Use the NAT pool name in the server farm submode, using the nat command, to specify which connections need to be client NATed.

To configure client NAT pools, perform this task:

	Command	Purpose
Step 1
	Router(config)# ip slb natpool pool-name	Configure a content switching NAT. You must
	start-ip end-ip netmask mask	create at least one client address pool to use this
		command1, 2.
Step 2	Router(config)# ip slb serverfarm	Enter the server farm submode to apply the
	serverfarm-name	client NAT.
