# Configuring Packet Redundancy for Circuits (CTP Menu)

The packet protector feature transmits one-for-one duplicate packets into the IP network, which enables a possible recovery scenario in the event of lost IP packets caused by transmission errors.

You can configure this feature on CTP, SAToP, and CESoPSN bundles.

Before you begin:

- Disable the bundle before you modify the bundle options.

To configure redundancy using the CTP Menu:

1. From the Main Menu, select 1) Bundle Operations.
2. Select the type of bundle that you want to configure.
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 2) Config.
5. Select 10) Advanced Options.
6. Configure option 9) Packet Protector(tm) as described in Table 1.

Field | Function | Your Action
--- | --- | ---
Packet Protector | Specifies whether the CTP device sends and/or receives cloned (duplicated) packets. This option is useful in networks where you expect significant IP packet loss. You need to configure the packet protector so that the setting at one end of the bundle corresponds with the setting at the other end of the bundle. For example, if you configure the local bundle to send cloned packets to the network, configure the remote bundle to expect cloned packets from the network. | Select: Disable packet protector—The CTP device does not send cloned packets over the IP network, and it ignores cloned packets that it receives. Send cloned packets to NET—The CTP device sends duplicated packets over the IP network. Expect cloned packets from NET—The CTP device uses cloned packets that it receives when the IP network drops the original packet. If the device receives both the original and cloned packets, it ignores the cloned packet. Send and expect cloned packets—The CTP device sends duplicated packets over the IP network. The CTP device uses cloned packets that it receives when the IP network drops the original packet. Send delayed cloned packets to NET—The CTP device sends duplicated packets after the interpacket delay of the circuit. Send delayed & expect cloned packets—The CTP device sends duplicated packets after the interpacket delay of the circuit. The CTP device uses cloned packets that it receives when the IP network drops the original packet. Expect cloned XOR packets—The CTP device uses cloned XOR packets that it receives when the IP network drops the original packet to regenerate the missing packet. If the device receives both the original and cloned XOR packets, it ignores the cloned packet. Send & expect cloned XOR packets—The CTP device sends duplicated XOR packets over the IP network. The CTP device uses cloned XOR packets that it receives to regenerate missing packets when the IP network drops the original packet.
