Configuring IP Parameters for SAToP Bundles (CTP Menu)

Remote Address

Specifies the name and IP address of the remote CTP device.

Enter the address of the remote CTP device.

Source UDP Port

For SAToP bundles that are using UDP as the transport protocol, specifies the source UDP port.

The source UDP port is used as the circuit identifier; you must configure both circuit endpoints to use the same UDP port. The UDP port must be unique on the CTP device. You will not be able to activate a port if another port is using the same source UDP port number.

Enter a number from 1 through 65535.

Outgoing MPLS Label

For SAToP bundles that are using GRE as the transport protocol, specifies the outgoing MPLS label.

This option appears only if you set the transport protocol to GRE.

The outgoing label must be configured to agree with the remote device. For example, if the outgoing label on the CTP device is 1000001, the incoming label on the remote device must be set to 1000001.

Enter a number from 299776 through 1000001.

Incoming MPLS Label

For SAToP bundles that are using GRE as the transport protocol, specifies the incoming MPLS label.

This option appears only if you set the transport protocol to GRE.

The incoming label must be configured to agree with the remote device. For example, if the outgoing label on the CTP device is 1000002, the outgoing label on the remote device must be set to 1000002.

Enter a number from 299776 through 1048575.

Packet Size

Specifies the size of IP packets that are created from data received at the serial port.

The CTP device makes sure that the combination of packet size and data rate does not result in a packet rate that exceeds 1200 packets per second.

Enter a number from 32 to 1456.

Min Buffer

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 0.001 through 9999.000 ms.

Pkt 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 0.001 through 9999.000 ms.

Max Buffer

Specifies the maximum buffer size. The maximum buffer ensures that the buffer does not become too large due to 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 (if used) or that you configure one port with adaptive clocking.

Enter a number from 0.001 through 9999.000 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 SAToP 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.

Time to Live

Specifies the maximum number of router hops that a packet can traverse. The CTP device sets the TTL value in IP packets that it sends to the IP network. The IP network does not alter or optimize the packet routing based on the TTL setting. You do not need to set the same TTL value on local and remote ports.

Enter a number from 0 through 255.

Transport

Specifies the transport protocol.

Select one:

• GRE

• UDP

Bundle Description

Specifies identifying information about the bundle.

Type a description for the bundle.
