Configuring TCS

• You must apply an IP policy to redirect Internet traffic to the cache servers. You can apply a

global or local policy. A global policy takes effect on all ports as soon as you configure the

policy. A local policy does not take effect until it is assigned to an interface. If you assign a local

policy, assign it to the output port connected to the Internet. The policy sends all HTTP traffic

addressed as output traffic to the port to the CPU instead for processing and forwarding.

• Although TCS can be concurrently be configured for cache servers with either IPv4 or IPv6

addresses, IPv4 traffic can only be directed to an IPv4 cache server and IPv6 traffic can only

be directed to an IPv6 cache server.

Defining a cache server

Once you have enabled TCS on the ServerIron ADX, assign a name and IP address to each cache

server. Once you have assigned the name and IP address, you can reference the server in CLI

commands by either the server’s name or its IP address.

To assign the names and IP addresses to the cache servers shown in Figure 9 on page 34, enter

commands such as the following.

For IPv4

ServerIronADX(config)# server cache-name server3 192.168.1.1

ServerIronADX(config-rs-server3)# server cache-name server4 192.168.1.2

ServerIronADX(config-rs-server4)# end

ServerIronADX# write memory

For IPv6

ServerIronADX(config)# server cache-name server1 2001:db8::1

ServerIronADX(config-rs-server1)# server cache-name server2 2001:db8::2

ServerIronADX(config-rs-server2)# end

ServerIronADX# write memory

Syntax: [no] server cache-name <text> { <ipv4-addr> | <ipv6-addr> }

The <text> variable specifies a name for the server. It can be any alphanumeric string of up to 42

characters.

The <ipv4-addr> variable specifies the IPv4 address of the web cache server.

The <ipv6-addr> variable specifies the IPv6 address of the web cache server.

Identify application ports for caching

For each defined cache server you must specify the ports whose traffic you want to cache. The

following example configures the previously named “server1” cache server to cache traffic from the

port: “http”, “ssl” and port number “8080”.

ServerIronADX(config)# server cache-name server1

ServerIronADX(config-rs-server1)# port http

ServerIronADX(config-rs-server1)# port ssl

ServerIronADX(config-rs-server1)# port 8080

Syntax: [no] port <portname or portnum>

NOTE

A maximum of 256 non-well-known ports (port number >1024) can be configured.
