Ethernet performance monitoring parameters

Overview

Alcatel-Lucent 1850 TSS-5 SYSCTL circuit pack provides PM capabilities for the Gigabit Ethernet interface on the VLNC50/52/55 circuit pack and Fast Ethernet interfaces on the VLNC35 circuit pack. PM data is collected at the interface for both incoming and outgoing directions and is stored in quarter-hour and day bins. The interface provides a connection to a SONET Virtual Concatenation Group (VCG).

Ethernet interfaces supported by the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs are monitored separately, using the CLI.

TCAs

Provisionable threshold crossing alerts (TCAs) are supported on the Ethernet interfaces.

Monitored parameters

The following table lists the performance parameters that Alcatel-Lucent 1850 TSS-5 monitors for the Ethernet interfaces on the VLNC50/52/55 and VLNC35 circuit packs, including the ranges for the 15-minute and 1-day (24-hour) registers.

Table 5-73: Ethernet performance parameters

Facility	Monitored Parameter	15-Min		1-Day
		Default	Range 1	Default	Range 1
Ethernet	Ethernet dropped frames (errors) (EDFE) 1	70,000	0–7,000,000	900,000	0–90,000,000
	Incoming number of bytes (EINB)	70,000	0–7,000,000	900,000	0–90,000,000
	Incoming number of frames (EINF)	70,000	0–7,000,000	900,000	0–90,000,000
	Outgoing number of bytes (EONB)	70,000	0–7,000,000	900,000	0–90,000,000
	Outgoing number of frames (EONF)	70,000	0–7,000,000	900,000	0–90,000,000

Enabling/disabling

Performance monitoring is enabled/disabled via the WaveStar^® CIT. From the System View menu, select Provision > Prov PM Ports, then navigate to the port.

VLNC50/52/55 and VLNC35 Ethernet parameters

Alcatel-Lucent 1850 TSS-5 monitors several Ethernet parameters.

Ethernet dropped frames (errors) (EDFE)

The EDFE parameter counts the number of incoming Ethernet frames dropped at a LAN/WAN port due to a frame check sequence (FCS) error or another defect in the frame.

Ethernet dropped frames (congestion) (EDFC)

The EDFC parameter counts the number of incoming Ethernet frames dropped at a LAN/WAN port due to congestion on the interface.

VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 Ethernet parameters

The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs are not controlled by the SYSCTL circuit pack and not monitored or managed through the WaveStar^® CIT. The VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs run independently and are managed via a separate CLI. For a detailed description of the Command Line Interface (CLI) messages used to interface with the VLNC40/VLNC42/VLNC42B/VLNC60/VLNC61/VLNC62/VLNC64 circuit packs and general information about using the Command Line Interface (CLI), refer to Alcatel-Lucent 1850 Transport Service Switch (TSS-5) Command Line Interface Guide.

In addition to the total number of packets received and transmitted from an interface, the following parameters can be displayed.

• Packets received without error

• Packets received with error

• Packets transmitted without error

• Transmit packet errors

• Collision frames

• Receive packets discarded

• Transmit packets discarded

PM parameters for VLNC42B Ethernet ports, ETS flows, pseudo-wires and tunnels

When operating in T-MPLS mode (Global Configuration Mode = tmpls), the VLNC42B and VLNC33 support specific performance monitoring parameters.

• The following Ethernet PM Aggregate Counters (through both Enhanced Current data Counters and Enhanced History Data Counters) are supported on UNI ports only:

  • Unicast Aggregate Counters

  • Multicast Aggregate Counters

  • Broadcast Aggregate Counters

• Incoming ETS Flow Counters (through both Enhanced Current data Counters and Enhanced History Data Counters) support counting of green and red packets only for up to 32 incoming ETS flows.

• Pseudowire and tunnel segments support the follow parameters:

  • MPLS Output Number of Packets

  • MPLS Input Number of Packets

  • MPLS Output Number of Bytes

  • MPLS Input Number of Bytes
