Configuring Circuit Startup Parameters for CTP Bundles (CTP Menu)

 

This topic describes how to configure advanced options that are related to circuit startup. Set these parameters to the same values on the local and remote CTP devices.

Before you begin:

  • Disable the bundle before you modify the bundle options.

To configure circuit startup parameters using the CTP Menu:

  1. From the CTP 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 2) Config.
  5. Select 10) Advanced Options.
  6. Configure options 4, 5, 6, 7, and 8 as described in Table 1.

FieldFunctionYour Action

Consecutive pkts loss to starve

Specifies how many consecutive circuit packets the IP network must drop before the CTP device restarts the circuit.

We recommend that you set the parameter to a larger value when the IP network uses packet-encrypting devices. These devices cause momentary interruption in packet flows when encryption keys are updated.

Enter a number from 1 through 64.

In sequence pkts after starve

Specifies the number of in-sequence packets the CTP device must receive after a starvation before the circuit transitions from in-sync to running.

Enter a number from 1 through 64.

OAM Chan Rate (pkt/sec)

Specifies the number of OAM packets per second that the circuit sends to the remote CTP device.

Enter a number from 1 through 255.

OAM pkts for Sync

Specifies the number of OAM packets that the circuit must receive before the state moves from no synchronization to in synchronization.

Enter a number from 1 through 255.

OAM pkts for Sync Loss

Specifies the number of received OAM packets that the CTP device misses before the state of the circuit moves from in synchronization to no synchronization.

Enter a number from 1 through 255.
