Configuring IP Parameters for VComp Bundles (CTP Menu)

The CTP software uses the IP parameters to create IP packets.

Before you begin:

  • Disable the bundle before you modify the bundle options.

To configure IP parameters for VComp bundles using the CTP Menu:

  1. From the Main Menu, select 1) Bundle Operations.
  2. Select 4) VCOMP.
  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 to configure the bundle.
  5. Configure the options as described in Table 5.

Table 5: VComp Bundle IP Parameter Settings in the CTP Menu

FieldFunctionYour Action

Destination IP

Specifies the IP address of the remote CTP device.

Enter the address of the remote CTP device.

Circuit ID

Specifies the bundle on the local CTP device.

You must use the same circuit ID for the VComp bundle at the remote CTP device.

Enter a number from 1 through 249.

Buffer Min

Specifies the minimum average buffer size. Use a value that is greater than the expected jitter and less than the Pkt Buffer Set parameter.

The minimum buffer ensures that the buffer does not become too small because of timing variances between the local and remote serial interfaces.

The entire buffer is available for accommodating and smoothing packet delay jitter, regardless of the minimum buffer setting.

Enter a number from 10 through 100 ms in increments of 10.

None of the buffer settings can be the same.

Buffer Set

Specifies the buffer size when the circuit enters a running state. This value must be large enough to accommodate the anticipated packet delay, and it must be set to a value greater than the minimum buffer size and lower than the maximum buffer size.

Enter a number from 20 through 100 ms in increments of 10.

None of the buffer settings can be the same.

Buffer Max

Specifies the maximum buffer size. The maximum buffer ensures that the buffer does not become too large because of timing variances between the local and remote serial interfaces. If the buffer size exceeds the maximum buffer size, the buffer is recentered to the Buffer Set value.

Periodic buffer recenters are not expected. If you notice recenters, we recommend that you verify the reference to the CTP device (if used) or that you configure one port with adaptive clocking.

Enter a number from 30 through 100 ms in increments of 10.

None of the buffer settings can be the same.

Service Type

Specifies the ToS byte to be used in the IP headers of packets sent from the CTP device to the IP network.

For a mapping of ToS byte values to DSCP classes and settings, see Providing QoS for VComp Bundles by Using Service Type Overview.

You do not need to set the ToS value to the same value on local and remote bundles.

Enter a number from 0 through 255.

Bundle Description

Specifies identifying information about the bundle.

Type a description for the bundle.
