  • Bundle Failover Between CTP Devices at the Same Site Overview
 

Configuring Bundle Failover Between CTP Devices at the Same Site

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.

  1. Configuring Y-Cable Redundancy for the Bundle (CTPView)
  2. Configuring Y-Cable Redundancy for the Bundle (CTP Menu)
  3. AutoSwitch for Bundle Failover (CTPView)

Configuring Y-Cable Redundancy for the Bundle (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:

  • Log in to the CTPView software at least at the Net_Admin level.
  • Connect the CTPView server to the CTP device for which you want to configure bundles.
  • Disable the bundle before you modify the bundle options.

To configure Y-cable redundancy by using CTPView:

  1. In the side pane, select Bundle > Configuration.
  2. Run your mouse over the Display and Select an Existing Bundle bar.
  3. In the table of bundles, select the bundle that you want to modify.
  4. Under Port Options, place a check mark in the Advanced Options Show check box to display advanced parameters, and configure the parameters described in Table 1.

  5. Click Click to Submit Bundle AND Port Changes.
  6. Configure AutoSwitch settings for bundle failover. See Configuring Bundle Failover Between CTP Devices at Alternate Sites (CTPView).

Table 1: Y-Cable Settings in CTPView

FieldFunctionYour Action

Y Cable Redundancy

Specifies whether or not a redundant Y cable is installed on the CTP device.

Select ENABLED or DISABLED.

Configuring Y-Cable Redundancy for the Bundle (CTP Menu)

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 2.
  7. Configure AutoSwitch settings for bundle failover. See Configuring Bundle Failover Between CTP Devices at Alternate Sites (CTPView).

Table 2: Y-Cable Settings in the CTP Menu

FieldFunctionYour Action

Y cable redundancy

Specifies whether or not a redundant Y cable is installed on the CTP device.

Select y or n.

AutoSwitch for Bundle Failover (CTPView)

This topic describes how to configure AutoSwitch for bundle failover. You can configure the AutoSwitch feature only with CTPView.

Before you begin:

  • Log in to the CTPView software at least at the Net_Admin level.
  • Connect the CTPView server to the CTP device for which you want to configure this feature.

To configure AutoSwitch by using CTPView:

  1. In the side pane, select System > Configuration.
  2. Set the AutoSwitch Daemon parameter to Enabled.
  3. Click Autoswitch.
  4. (Optional) You can update the network interface device (NID) information for all CTP devices that are reachable in the network. To do so, click Update NID info in the Remote Host Settings row.
  5. Configure the parameters under AutoSwitch Bundle Failover Settings as described in Table 3, and click Submit Settings.

Table 3: AutoSwitch Parameter Settings in CTPView

FieldFunctionYour Action

Status

Specifies whether the AutoSwitch feature is enabled or disabled on the bundle.

Select one:

  • Disabled—AutoSwitch is disabled for this bundle.
  • Enabled—AutoSwitch is enabled for this bundle.

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:

  1. Click the box under AutoSwitch Primary, and select a group.

    A list of CTP devices within the group appears.

  2. Select a CTP device.

    A list of the circuit IDs configured on the CTP device appears.

  3. Select a circuit ID.

    A list of interfaces configured with the circuit ID appears.

  4. Select an interface.

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:

  1. Click the box under AutoSwitch Primary, and select a group.

    A list of CTP devices within the group appears.

  2. Select a CTP device.

    A list of the circuit IDs configured on the CTP device appears.

  3. Select a circuit ID.

    A list of interfaces configured with the circuit ID appears.

  4. Select an interface.

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:

  • Disabled—The CTP device does not check the connectivity to the primary device.
  • Enabled—The CTP device checks the connectivity to the primary CTP device after a switchover. If the primary device becomes available, the CTP device reconnects to the primary CTP device.
