Example 2—Unprotected Flexible Inline, Two Collector Maps

Example 2 adds an inline network to Example 1. It has the same five inline tools, and adds a collector map for the second inline network. In the second collector map, two of the five tools are specified, sending traffic through those two tools, the first and the third tools in the sequence. The inline networks share these two tools.

The inline network aliases are n0102 to n0304, based on ports x1 to x4.

For example, the inline tools can be Web Application Firewall (WAF), Intrusion Prevention System (IPS), Advanced Persistent Threat (APT).

The inline tool aliases are t0708 to t1516, based on ports x7 to x16.

1 Example 2 Inline Tool Sharing by Multiple Inline Flows illustrates Example 2. Traffic is only shown in one direction.

Use the following steps to configure Example 2:

Step

Description

Command
1.    

Configure inline network ports, port type (inline-network), and administratively enable inline network ports.

(config) # port 1/3/x1..x4 type inline-network

(config) # port 1/3/x1..x4 params admin enable
2.  

Configure inline networks.

(config) # inline-network alias n0102 pair net-a 1/3/x1 and net-b 1/3/x2

(config) # inline-network alias n0304 pair net-a 1/3/x3 and net-b 1/3/x4
3.  

Configure inline tool ports, port type (inline-tool), and administratively enable inline tool ports.

(config) # port 1/3/x7..x16 type inline-tool

(config) # port 1/3/x7..x16 params admin enable
4.  

Configure inline tools, specify that the inline tool is going to be shared by different sources, and enable them.

(config) # inline-tool alias t0708 pair tool-a 1/3/x7 and tool-b 1/3/x8

(config) # inline-tool alias t0708 shared true

(config) # inline-tool alias t0708 enable

(config) # inline-tool alias t0910 pair tool-a 1/3/x9 and tool-b 1/3/x10

(config) # inline-tool alias t0910 shared true

(config) # inline-tool alias t0910 enable

(config) # inline-tool alias t1112 pair tool-a 1/3/x11 and tool-b 1/3/x12

(config) # inline-tool alias t1112 shared true

(config) # inline-tool alias t1112 enable

(config) # inline-tool alias t1314 pair tool-a 1/3/x13 and tool-b 1/3/x14

(config) # inline-tool alias t1314 shared true

(config) # inline-tool alias t1314 enable

(config) # inline-tool alias t1516 pair tool-a 1/3/x15 and tool-b 1/3/x16

(config) # inline-tool alias t1516 shared true

(config) # inline-tool alias t1516 enable
5.  

Configure collector maps from inline networks to inline tools in both directions, add user-defined tags, and enable maps.

Note:  The tag is optional. The default is auto, which automatically assigns tags.

(config) # map alias FLEX1

(config map alias FLEX1) # type flexInline collector

(config map alias FLEX1) # from n0102

(config map alias FLEX1) # a-to-b t0708,t0910,t1112,t1314,t1516

(config map alias FLEX1) # b-to-a reverse

(config map alias FLEX1) # tag 100

(config map alias FLEX1) # enable

(config map alias FLEX1) # exit

(config) #

(config) # map alias FLEX2

(config map alias FLEX2) # type flexInline collector

(config map alias FLEX2) # from n0304

(config map alias FLEX2) # a-to-b t0708,t1112

(config map alias FLEX2) # b-to-a reverse

(config map alias FLEX2) # tag 200

(config map alias FLEX2) # enable

(config map alias FLEX2) # exit

(config) #
6.  

Configure the path of the traffic to inline tools.

(config) # inline-network alias n0102 traffic-path to-inline-tool

(config) # inline-network alias n0304 traffic-path to-inline-tool
