Ethernet service management
Overview
The Ethernet services are managed by provisioning the following:
For detailed information about provisionable parameters and their values, see Performance monitoring.
Tagging (VLAN) modes
Alcatel-Lucent 1665 DMX supports the Private Line, transparent, and 802.1Q tagging modes. Tagging modes are provisioned on a circuit pack basis. Changing tagging modes will impact service. For detailed information about the tagging modes, see Tagging Modes and the WaveStar® CIT online help.
Cross-connections
The following types of cross-connections are used with Ethernet circuit packs.
For detailed information about supported cross-connections refer Cross-connections in Chapter 6, System planning and engineering and the WaveStar® CIT online help.
Cross-connections with SONET layer protection
All SONET protected services are implemented using 1way or 1wayPR cross-connections. They are used to form a pair of bidirectional links between a VCG port and one side of a SONET tributary. 1way or 1wayPR cross-connection use two VCGs on LNW66 Ethernet circuit packs and one VCG on all other Ethernet circuit packs (LNW63, LNW64, LNW73, LNW73C, LNW74, LNW87, LNW170). 1way or 1wayPR cross-connections are described in Protected tributaries. The use of VCG ports is summarized in VCG (WAN) ports.
Cross-connections without SONET layer protection
Services that are not protected by the SONET layer are provisioned using either 1way or 1way unswitched cross-connections.
1way cross-connections can be used to provide unprotected services on BLSRs, only if the tributary (time slot) is provisioned to carry non-preemptible unprotected traffic (NUT). The BLSR tributary(s) must be provisioned for NUT before the cross-connection is established or protected services are provided. A packet ring bandwidth could be split between working and protection (extra traffic) freeing up protected working bandwidth for other TDM services. 1way cross-connections can be used to provide unprotected services over BLSR w/ NUT, but they are less efficient than 1way unswitched cross-connections.
1way unswitched cross-connections can be used to provision unprotected traffic on UPSRs. One cross-connection can be made between a VCG port and one side of the SONET ring, and the other can be made between the paired VCG and the other side of the SONET ring.
Unprotected cross-connections (1way unswitched) to UPSRs and BLSRs w/ NUT are all provisioned independently per VCG.
This pairing of VCG ports and USPR unprotected cross-connections is described in Unprotected tributaries. The use of VCG ports is summarized in VCG (WAN) ports.
Cross-connection types and supported configurations
The number of Private Line Services and Packet Rings an Ethernet circuit pack can support is dependent on the type of cross-connection used and whether SONET layer protection is used.
The following table shows the cross-connection types and supported services.

Notes:
A mix of VT1.5, STS-1, & STS-3c connections allowed; Max of 336 VT1.5 (12 STS-1s) of VT1.5 cross connect capacity.
When using small or medium fabric MAINs, the small value reflects the capacity for function groups A, B, & C. Values for function groups D & G are represented by the larger value. When using all large fabric MAINs, ALL function groups support the larger value.
SONET protection is provided if NUT is not provisioned, and disabled if NUT is provisioned.

LAN ports
All LAN ports have characteristics that must be the same on both 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, see Ethernet/SAN circuit packs.
The Configuration → Provision Equipment WaveStar® CIT command is used to provision LAN ports. For more information about the Configuration → Provision Equipment command and LAN port provisioning, see the WaveStar® CIT online help.
VCG (WAN) ports
The Configuration → Provision Equipment WaveStar® CIT command is used to provision VCG (WAN) ports. For more information about the Configuration → Provision Equipment command and VCG (WAN) port provisioning, see the WaveStar® CIT online help.
The following table shows the available VCG (WAN) ports available on Ethernet circuit packs.

Notes:
All 24 VCGs are available only when unswitched cross-connections are used. Only 12 VCGs are available if protected cross-connections are used.
Only VCG1 is available when protected cross-connection is used.
VCG2 is not available when protected cross-connection is used on VCG1. VCG4 is not available when protected cross-connection is used on VCG3
Although the LNW74 can be used in slot G1, only the optical ports are functional. When mixing an LNW74 with an optical only pack, all 24 ports (16 electrical and 8 SFP) ports on the LNW74 are available. When pairing the LNW74 with another LNW74, ONLY the 8 SFP ports on each pack are usable, for a total of 16 SFP ports per function group
When a VLF Main pack (LNW59, LNW82, or LNW504) is used, Alcatel-Lucent 1665 DMX allows Ethernet packs to be installed in Slot 1 and/or 2 of a function unit or growth slot. Certain circuit pack/slot equipage restrictions apply. For more information see Very large fabric (VLF) engineering rules. When VLF Mains are not used, Ethernet packs, except for the LNW170 in protected mode, can only be installed in Slot 1 of a function unit or growth slot. When it is in protected mode, the LNW170 can occupy both slots with VLF or non-VLF Mains installed.
Virtual switch
A virtual switch is a logical grouping of LAN ports and VCG ports that share interconnect and share a common set of properties. A virtual switch may support one or more spanning trees; a spanning tree can only belong to one virtual switch.
A port (LAN or VCG) can only be assigned to one virtual switch at a time. On the LNW66 packs VLANs (802.1Q mode) and port tags (transparent mode) that are assigned to a virtual switch cannot be assigned to another virtual switch on the same circuit pack.
The LNW170 circuit packs can support a maximum of 16 virtual switches on each circuit pack (LNW66 support 2).
The following WaveStar® CIT commands support virtual switch provisioning:
For more information about provisioning virtual switches and the WaveStar® CIT commands, see the WaveStar® CIT online help.
Quality of service (QoS)
The following Quality of Service (QoS) parameters are provisionable using the WaveStar® CIT.
-
Peak information rate (PIR) is provisioned on a VLAN/port TAG or on a LAN port basis for protected Private Line.
-
Credit interval for adding tokens to the token buckets used by the PIR
For more information about Quality of Service, see Quality of Service and QoS services (LNW170). For more information about the provisionable QoS parameters, see the WaveStar® CIT online help.
Performance monitoring
Each Ethernet port has associated performance monitoring parameters and counters. The counters are provided for incoming and outgoing frames. For detailed information about Ethernet performance monitoring parameters, see Performance monitoring.
Remote Client Fail Reverse Defect Indication
This parameter is used to enable/disable the reverse direction of two-way Auto Link Shutdown (ALS) using GFP RDI control frames and may have one of the following values:
This parameter applies to both FE and GE interfaces on the LNW63, LNW64, LNW70, LNW74, LNW87, and LNW170.
This parameter is significant when both Remote Client Fail and Remote Client Fail Link Shutdown are enabled.
