Example 3: Protected Inline Bypass Using Combo Modules

Example 3 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/x19and 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.

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.

 

Task	Description	UI Steps

In the Alias field, type InTool2. 23. For Port A, select iT3. 24. For Port B, select iT4. 25. Under Configuration: a. Select Enabled b. Select Enabled Heartbeat and set Profile to hb_custom. 26. Click Save.
5.	Configure the inline tool group and enable it.	1. Select Inline Bypass > Inline Tool Group 27. Click New. 28. In the Alias field, type inToolGroup. 29. For Inline Tools, select InTool1 and InTool2. 30. Under Configuration, select Enabled. 31. Click Save.
6.	Configure map passall, from inline network to inline tool.	1. Select Maps > Maps. 32. Click New. 33. In the Alias field, type InMap. 34. Select Inline for Type and Pass All for Subtype. 35. For Source, select default_inline_net_2_2_1 36. For Destination, select InTool1 37. Click Save.
7.	Configure the path of the traffic to inline tool and disable the physical bypass	1. Select Inline ByPass > Inline Networks. 38. Select the Inline Network default_inline_net_2_2_1 and click Edit 39. Under Configuration, set the Traffic Path field to To Inline Tool. 40. Make sure Physical Bypass is not selected. 41. Click Save.
