# Configuring Bundle Failover Between CTP Devices at Both the Local and Remote Sites (CTP Menu)

To set up Y-cable redundancy at both the local and remote sites, you configure two bundles—a master bundle and a backup bundle. Each bundle follows a different path between the two sites, as shown in Figure 1.

Figure 1: Y-Cable Redundancy at Both the Local and Remote Sites

When you configure Y-cable redundancy, you can use different redundant port numbers if the devices are using the same port on the 100-pin connector. For example, a Y cable 100-pin connector could be attached to ports 0-3 on the first CTP device, with the second connector attached to ports 8-11 on the second device. The redundant ports would be P0/P8, P1/P9, P2/P10, and P3/P11 on the first and second CTP devices, respectively.

Before you begin:

- Disable the bundle before you modify the bundle options.

To configure Y-cable redundancy for CTP bundles by using the CTP Menu:

1. From the Main Menu, select 1) Bundle Operations.
2. Select 1) CTP.
3. Select a bundle from the list.

   If you select an active bundle, you are prompted to disable the bundle before configuring it.

4. Select 3) Port Config.
5. Select 4) Advanced Options.
6. Configure the options as described in Table 1.

Field | Function | Your Action
--- | --- | ---
Y cable redundancy | Specifies whether or not a redundant Y cable is installed on the CTP device. Enable this parameter for both primary and backup bundles. | Select y or n.
Y cable master | Specify whether or not this bundle is the master bundle. | Select y or n.
