# Configuring IP Parameters for VComp Bundles (CTPView)

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

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 IP parameters for VComp bundles 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 Bundle Options, configure the parameters described in Table 1, and click Click to Submit Bundle AND Port Changes.

Table 1: VComp Bundle IP Parameter Settings in CTPView

Field | Function | Your Action
--- | --- | ---
Bundle Description | Specifies identifying information about the bundle. | Type a description for the bundle.
State | Specifies whether the bundle is active or disabled. | Select DISABLED or ACTIVE.
Remote Address | Specifies the name and IP address of the remote CTP device. | In the first field, select the CTP device. In the second field, select an interface on the 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.
Min Buffer | Specifies the minimum average buffer size. Use a value that is greater than the expected jitter and less than the 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. | Select a number from 10 to 80 ms.
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. | Select a number from 20 through 90 ms.
Max Buffer | 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. | Select a number from 30 through 100 ms.
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.
Calculated Packet Size | VComp packet size is calculated automatically depending on the number of DS0s and channels in the VComp bundle. |
