Inline Bypass Solution Examples

The following sections provide examples of inline bypass solutions. The solutions are presented in an order from simple to complex. Refer to the following:

■   Example 1: Unprotected Inline Bypass with an Inline Tool Group
■   Example 2: Unprotected Inline Bypass with Default Heartbeat
■   Example 3: Protected Inline Bypass Using Combo Modules

 

Example 1: Unprotected Inline Bypass with an Inline Tool Group

Example 1 is a simple, unprotected inline bypass solution. In the example, aliases are used for inline network ports (iN1 and iN2), inline tool ports (iT1 and iT2), inline network (inNet), inline tool (inTool), and inline map (inMap).

On GigaVUE‑HC3, an unprotected inline bypass solution can be configured on the bypass combo module with the inline networks and inline tools on ports 1/1/x1..x16 or on ports c1..c4, or on any other module on the GigaVUE‑HC3 node.

On GigaVUE‑HC1-Plus, an unprotected inline bypass solution can be configured with the inline networks and inline tools on ports 1/1/x1..x16 or on ports x17..x24, or on any other module on the GigaVUE‑HC1-Plus node. Refer to 1 Logical Bypass Without Bypass Combo Module which shows a GigaVUE‑HC1-Plus.

1 Logical Bypass Without Bypass Combo Module

On GigaVUE‑HC1-Plus, an unprotected inline bypass solution can be configured on the base module, with the inline networks and inline tools on ports 1/1/x1..x12 and 1/1/g1..g4, or on the bypass combo module on ports x1..x4.

Example 3: Protected Inline Bypass Using Combo Modules

Example 3 is a protected inline bypass solution using bypass combo modules on GigaVUE‑HC3. 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‑HC3, 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.
