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.
