Gigamon Protected Inline Bypass Using Bypass Combo Modules

Example 4 is a protected inline bypass solution using bypass combo modules on GigaVUE-HC2. It also configures heartbeat and negative heartbeat profiles.

Protected inline networks are based on the pairs of ports associated with the physical protection switches located on the bypass combo modules. Unlike the unprotected examples, you do not need to configure inline network ports because they are created automatically. On GigaVUE-HC2, the port pairs are numbered for example: 2/2/x17 and 2/2/x18, 2/2/x19 and 2/2/x20, 2/2/x21 and 2/2/x22, 2/2/x23 and 2/2/x24.

You do not need to configure inline networks because they are also created automatically on bypass combo modules. The aliases of the default inline networks are: default_inline_net_2_2_1, default_inline_net_2_2_2, default_inline_net_2_2_3, default_inline_net_2_2_4.

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. It can also be configured 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. For an example, refer to Example to Configure Inline Bypass on H Series Nodes.

Note: The default value of the physical-bypass attribute of protected inline networks is set to enable, which means that the fibers attached to ports net-a and net-b of the inline network are optically coupled and the traffic is exchanged between end nodes without coming to the switching fabric of the GigaVUE node. As shown in Example 4, after configuring the inline tool and the map passall, the physical-bypass attribute is set to disable in order to activate the inline-bypass solution.

Step

Description

Command

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

(config) # port 2/2/x11 alias iT1
(config) # port iT1 type inline-tool
(config) # port iT1 params admin enable

(config) # port 2/2/x12 alias iT2
(config) # port iT2 type inline-tool
(config) # port iT2 params admin enable

2. Configure heartbeat profile alias.

(config) # hb-profile alias hb2
(config hb-profile alias hb2) # exit
(config) #

3. Configure negative heartbeat profile alias and PCAP file.

(config) # nhb-profile alias nhb1
(config nhb-profile alias nhb1) # custom-packet http://remote/home/hnb.pcap
(config nhb-profile alias nhb1) # exit
(config) #

4. Configure inline tool. Also specify the heartbeat profile, the negative heartbeat profile, enable heartbeat and negative heartbeat, and also enable inline tool.

(config) # inline-tool alias inTool1
(config inline-tool alias inTool1) # pair tool-a iT1 and tool-b iT2
(config inline-tool alias inTool1) # hb-profile hb2
(config inline-tool alias inTool1) # nhb-profile nhb1
(config inline-tool alias inTool1) # heart-beat
(config inline-tool alias inTool1) # negative-heart-beat
(config inline-tool alias inTool1) # enable
(config inline-tool alias inTool1) # exit
(config) #

5. Configure map passall, from inline network to inline tool.

(config) # map-passall alias inMap1
(config map-passall alias inMap1) # from default_inline_net_2_2_1
(config map-passall alias inMap1) # to inTool1
(config map-passall alias inMap1) # exit
(config) #

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

(config) # inline-network alias default_inline_net_2_2_1 traffic-path to-inline-tool

7. Disable physical bypass on the default inline network alias.

(config) # inline-network alias default_inline_net_2_2_1 physical-bypass disable

8. Display the configuration for this example.

(config) # show port
(config) # show inline-network
(config) # show inline-tool
(config) # show map
(config) # show hb-profile
(config) # show nhb-profile
