To configure bundle failover between CTP devices at the same site that are connected by a Y cable, perform the tasks below. You can configure Y-cable redundancy for the bundle with either CTPView or CTP Menu. You can configure AutoSwitch only with CTPView.
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:
To configure Y-cable redundancy by using CTPView:
Table 1: Y-Cable Settings in CTPView
Field | Function | Your Action |
---|---|---|
Y Cable Redundancy | Specifies whether or not a redundant Y cable is installed on the CTP device. | Select ENABLED or DISABLED. |

To configure Y-cable redundancy for CTP bundles by using the CTP Menu:
If you select an active bundle, you are prompted to disable the bundle before configuring it.
Table 2: Y-Cable Settings in the CTP Menu
Field | Function | Your Action |
---|---|---|
Y cable redundancy | Specifies whether or not a redundant Y cable is installed on the CTP device. | Select y or n. |
This topic describes how to configure AutoSwitch for bundle failover. You can configure the AutoSwitch feature only with CTPView.
Before you begin:
To configure AutoSwitch by using CTPView:
Table 3: AutoSwitch Parameter Settings in CTPView
Field | Function | Your Action |
---|---|---|
Status | Specifies whether the AutoSwitch feature is enabled or disabled on the bundle. | Select one:
|
Switch Count | Specifies how many consecutive checks are required without a circuit being established before the circuit is switched over to an alternate circuit. The combination of the switch count value and the check period value determines the rate of the switchover. | Select the number of checks. We recommend that you configure the Switch Count and Check Period to values that prevent the circuit from switching in the event of a short transient outage. |
Check Period | Specifies the time between the checking of ports to determine the circuit status. The combination of the switch count value and the check period value determines the rate of the switchover. | Select the number of seconds. We recommend that you configure the Switch Count and Check Period to values that prevent the circuit from switching in the event of a short transient outage. |
AutoSwitch Primary | Specifies the CTP device that is used as the primary device to fail over to. Also specifies the circuit ID and interface that are used on the device. | To specify the primary device:
|
AutoSwitch Secondary | Specifies the CTP device that is used as the secondary device to fail over to. Also specifies the circuit ID and interface that are used on the device. | To specify the secondary device:
|
Secondary Revert | Specifies whether or not the CTP device periodically checks the connectivity to the AutoSwitch primary device after a switchover to the secondary device. | Select one:
