Ethernet service management

Overview

The Ethernet services are managed by provisioning the following:

• Cross-connections

• LAN ports

• VCG (WAN) ports

• Performance monitoring.

• Class of service

For detailed information about available parameters and their values, refer to Ethernet performance monitoring parameters in Chapter 5, Operations, administration, maintenance, and provisioning.

Cross-connections

The following types of cross-connections are support on Ethernet ports on the VLNC35 and VLNC50/52/55 circuit packs.

• 2wayPR

• 2way

For detailed information about supported cross-connections refer to Chapter 6, System planning and engineering in this document.

Cross-connection types and supported configurations

The following table shows the cross-connection types and supported services.

Notes:

1. The VLNC35 circuit packs supports a total bandwidth of 8 STS1/TUG3 when used with VLNC50/52/55 circuit pack.

2. The WaveStar^® CIT provides a backplane utilization report and on-demand backplane utilization optimization.

LAN ports

All LAN ports have characteristics that must be the same on all sides of a link. Some characteristics are strictly physical in nature. They can only be changed by using different equipment. Some examples of these characteristics are cable type (for example, twisted pair, fiber) and optical type (short reach, long reach). For more information about the Ethernet circuit packs, refer to Chapter 4, Product description.

The Configuration → Equipment WaveStar^® CIT command is used to provision LAN ports.

VCG (WAN) ports

The Configuration → Equipment WaveStar^® CIT command is used to provision VCG (WAN) ports.

The VLNC50/52/55 circuit pack has a single private-line LAN port with a single associated VCG. The VLNC35 circuit pack has a 6 private-line LAN ports, each with a single associated VCG. Once the first cross-connection is established to a VCG, all subsequent cross-connections must be of the same rate.

Performance monitoring

Each Ethernet port has associated performance monitoring parameters and counters. The counters are provided for incoming and outgoing frames. For more information, refer to Ethernet performance monitoring parameters in Chapter 5, Operations, administration, maintenance, and provisioning.
