Gigamon OOB Maps Originating from Inline Network Group

Example 15 expands on Example 14 by combining out-of-band (OOB) maps with a map passall originating from an inline network group on GigaVUE-HC2.

When the source port of an OOB map is associated with an inline network group, only one port is supported in the port list. In this case, multiple OOB maps are needed because each OOB map only accepts one inline network port as the input (the from argument of the map command).

A protected inline network (which uses bypass combo modules) is included in Example 15. You do not need to configure inline network ports or the inline networks because they are created automatically. The port pairs in Example 15 are
1/1/x17 and 1/1/x18, as well as 1/1/x19 and 1/1/x20. The aliases of the default inline networks in Example 15 are default_inline_net_1_1_1 and default_inline_net_1_1_2.

In Example 15, two OOB maps send traffic from each inline network port (associated with default_inline_net_1_1_1) to the OOB tool. Two more maps would be needed to send traffic from each inline network port (associated with default_inline_net_1_1_2) to the OOB tool, but this is not included in Example 15.

On GigaVUE-HC3, protected inline bypass can be configured on the bypass combo module on ports c1..c4.

On GigaVUE-HC1, protected inline bypass can be configured on the bypass combo module, or on the TAP-HC1-G10040 module placed in either bay 2 or bay 3, so the ports will be 1/2/g1..g8 or 1/3/g1..g8. On the TAP module, you will need to configure inline network ports and the inline network because they are not created automatically (as they are on bypass combo modules).

Step

Description

Command

1. Configure an inline network group consisting of two protected inline networks.

(config) # inline-network-group alias inNetGroup
(config inline-network-group alias inNetGroup) # network-list default_inline_net_1_1_1,default_inline_net_1_1_2
(config inline-network-group alias inNetGroup) # exit
(config) #

2. Configure a regular tool port of port type (tool) and administratively enable it. This is the OOB tool.

(config) # port 1/1/x12 type tool
(config) # port 1/1/x12 params admin enable

3. Configure two inline tool ports of port type (inline-tool) and administratively enable them.

(config) # port 1/2/x23 type inline-tool
(config) # port 1/2/x23 params admin enable

(config) # port 1/2/x24 type inline-tool
(config) # port 1/2/x24 params admin enable

4. Configure inline tool and enable it. Also, specify that the inline tool is going to be shared by different sources. When shared is enabled (true), the inline tool can receive traffic from multiple sources (the inline networks in the inline network group).

(config) # inline-tool alias inTool1 pair tool-a 1/2/x23 and tool-b 1/2/x24
(config) # inline-tool alias inTool1 enable
(config) # inline-tool alias inTool1 shared true

5. Configure a map passall, from the inline network group to the inline tool. This sends all the traffic to the inline tool.

(config) # map-passall alias inline_map1
(config map-passall alias inline_map1) # from inNetGroup
(config map-passall alias inline_map1) # to inTool1
(config map-passall alias inline_map1) # exit
(config) #

6. Configure the first rule-based map. This is an OOB map from one inline network port (associated with default_inline_net_1_1_1) to the OOB tool.

(config) # map alias OoB_map1
(config map alias OoB_map1) # type regular byRule
(config map alias OoB_map1) # rule add pass ipver 4
(config map alias OoB_map1) # to 1/1/x12
(config map alias OoB_map1) # from 1/1/x17
(config map alias OoB_map1) # exit
(config) #

7. Configure a second rule-based map. This is an OOB map from the other inline network port (associated with default_inline_net_1_1_1) to the OOB tool.

(config) # map alias OoB_map2
(config map alias OoB_map2) # type regular byRule
(config map alias OoB_map2) # rule add pass ipver 4
(config map alias OoB_map2) # to 1/1/x12
(config map alias OoB_map2) # from 1/1/x18
(config map alias OoB_map2) # exit
(config) #

8. Configure a third rule-based map. This is an OOB map from a single inline tool port to the OOB tool.

(config) # map alias OoB_map3
(config map alias OoB_map3) # type inline byRule
(config map alias OoB_map3) # rule add pass ipver 4
(config map alias OoB_map3) # to 1/1/x12
(config map alias OoB_map3) # from 1/2/x23
(config map alias OoB_map3) # exit
(config) #

9. Configure the path of the traffic to inline tool.

(config) # inline-network alias default_inline_net_1_1_1 traffic-path to-inline-tool
(config) # inline-network alias default_inline_net_1_1_2 traffic-path to-inline-tool

10. Disable physical bypass on the default inline network aliases.

(config) # inline-network alias default_inline_net_1_1_1 physical-bypass disable
(config) # inline-network alias default_inline_net_1_1_2 physical-bypass disable

11. Display the configuration and statistics for this example.

(config) # show inline-network
(config) # show inline-network-group
(config) # show inline-tool
(config) # show map
