Configuring Y-Cable Redundancy for the Bundle (CTPView)
A CTP series device provides two types of Y-cable redundancy.
Redundancy by using a hardware link that uses a special Y cable—A hardware link requires a special Y cable that connects the CTP devices and is supported only on serial ports. The functioning of a hardware link is similar to the default operation of the redundancy feature in CTPOS Release 6.5 and earlier. A hardware link is supported only on serial ports.
Redundancy by using a software link that does not depend on a signaling hardware like the Y cable—A software link does not require a special signaling hardware. Y-cable port pairs can maintain contact with each other by means of OAM packets instead of a hardware signaling path. Because of this, Y-cable redundancy is supported on T1E1 ports as well as serial ports with a special Y cable. Redundancy by means of a software link is supported on both serial and T1/E1 ports on CTP150 and CTP2000 devices.
When you configure Y-cable redundancy that uses a hardware link, 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:
- In the side pane, select Bundle > Configuration.
- Run your mouse over the Display and Select an Existing Bundle bar.
- In the table of bundles, select the bundle that you want to modify.
- 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.
- Click Click to Submit Bundle AND Port Changes.
- Configure AutoSwitch settings for bundle failover. See Configuring Bundle Failover Between CTP Devices at Alternate Sites (CTPView).
Table 1: Y-Cable Settings in CTPView
Field | Function | Your Action |
---|---|---|
Redundancy Mode | Displays a list of supported redundancy modes. See Redundancy Features Overview for a list of supported Y-cable redundancy configuration settings. | Select one:
|
Primary/Secondary | Specifies the primary and backup bundles. | Configure a primary and a backup bundle. When the software link is enabled and link partners are specified, the software verifies that there is a matched primary and backup pair. |
Pri/Sec Link Type | Specifies the link types for primary and back up bundle. | Select one.
|
IP Address | Specifies an IP address for the other port of the redundant primary and backup pair. | Specify an IP address. |
Card Number | Specifies a card number for the other port of the redundant primary and backup pair. | Specify a card number in the range 0 through 6. |
Port Number | Specifies a port number for the other port of the redundant primary and backup pair. | Specify a port number in the range 0 through 23. |
Fast switch | Allows fast switching in case of a failover. This feature is supported only on serial ports. Fast switch is supported only in Hot standby in Revert redundancy mode and is valid only for a hardware link. | Select ENABLED or DISABLED. |
