Procedure 11-38.2: Create LAG on new LNW170 circuit packs (protected)

- Overview

Use this procedure to create LAG groups on new LNW170 circuit packs.

If an LNW170 is already installed/in-service in one of the function/growth slots, use Procedure 11-38.4: Create LAG, one slot already equipped with LNW170 circuit pack with VLF Mains or Procedure 11-38.5: Create LAG, one slot already equipped with LNW170 circuit pack with non-VLF Mains to create the LAG group.

Provisioning LAG groups on protected LNW170 circuit packs differs from provisioning LAG groups on unprotected LNW70/170 circuit packs. LAG groups on protected LNW170 circuit packs are automatically created by setting the Slot Protection State parameter to PROT on the pair of LNW170 circuit packs.

The general rules in provisioning a protected LNW170 service are:

  • Equipping both slots in the Function/Growth group with LNW170 cards.

  • Provisioning the VLAN Tagging Mode parameter (vlantagmd) to Switched.

  • Provisioning the Ethernet Cross Connect Mode paramenter (eccmode) the same on both circuit packs.

  • Provisioning the Port Configuration parameter (enetmd) the same on both circuit packs.

  • Provisioning the Transmission Audit parameter (taudit) the same on both circuit packs.

  • Provisioning the circuit pack Slot Protection State parameter (prot_state) to Protected (PROT).

Important!

It is recommended that cables associated with members of a LAG not be connected until the group is defined, else a loop may be formed.

- Privilege level

You must login at least as a General user to complete this procedure.

- Before you begin

Prior to performing this procedure, refer to Before you begin and Required equipment in this chapter and you must have complete work instructions for this procedure that detail:

  • The shelf slots, circuit packs, ports being provisioned.

  • The LAN ports and LAG group parameters being assigned.

Steps

Use the following procedure to create a link aggregation group on protected LNW170 circuit packs.

 
1

Use the WaveStar® CIT to log in to the Alcatel-Lucent 1665 DMXtend shelf.

Reference:

Procedure 14-2: Connect Personal Computer (PC) and establish WaveStar® CIT session

2

Install a LNW170 into function/growth slot 1.

Reference:

Procedure 4-14: Install Gigabit Ethernet circuit packs

3

From the System View, select Configuration → Equipment, select the installed LNW170 100/1G FXS circuit pack in slot 1, then click Select. Provision the Slot Protection State to PROT, VLAN Tagging Mode to SWITCHED, Ethernet Cross Connect Mode, Transmission Audit, and Port Configuration from your work instructions. Provision other parameters as required.

Result:

The LAG protection groups 1–4 are created and slot 1 Switch State becomes Active-WAN.

The unequipped slot becomes provisioned for a LNW170. The unequipped slot is also provisioned for VLAN Tagging Mode (vlantagmd) of SWITCHED, and for the same values of Ethernet Cross Connect Mode (eccmode), Port Configuration (enetmd), Transmission Audit (taudit) and VCG parameters as the installed LNW170 circuit pack.

4

Install a LNW170 into companion function/growth slot 2.

5

If required, use the TL1 ed-eport command to provision the LAG member LAN ports and LAG port parameters, or select Configuration → Equipment from the System View menu. Expand the details for the circuit pack, select the LAG group or expand the details for the LAG group, highlight the member LAN port, then click Select. Provision the parameters as required.

Reference:

Procedure 11-8: Provision Ethernet LAN port parameters

6

If required, use the TL1 ent-erate command to provision the LAG related QoS parameters, or select Configuration → Data → Provision QoS Service from the System View menu. Expand the details for the circuit pack, highlight the LAG port, then click Select. Provision the parameters as required.

Reference:

Procedure 11-23: Provision Ethernet quality of service (QoS) - LNW70/LNW170

7

If required, use the TL1 ed-lagrp command to modify the LAG, or select Configuration → Data → Create/Modify/Delete LA Group from the System View menu. Select (highlight) the circuit pack, then click Select.

Modifying a LAG consists of changing the hashtype, or changing the protocol parameter.

  • Hash Type

    The basis for assigning a conversation to a link.

    . Valid values are:

    • MAC - Use Source Address/Destination Address (SA/DA) (initial value)

    • IP - Use Source IP Address/Destination IP Address (SIP/DIP). This may allow better load distribution when connected to a router where the MAC SA/DA are constant or nearly constant and the traffic is IP.

  • Protocol.

    The protocol used for Link Aggregation.

    Valid values:

    • LACP - IEEE Std 802.3™-2002 Link Aggregation Control Protocol (initial value).

    • NONE - Aggregation among members is forced. Any Link Aggregation protocol messages received are ignored and none are sent.

8

Click twice in the Hash Type or Protocol box. Select the Hash Type or Protocol value, as required. Click Apply, read the warning message then click Yes to execute the command. Click Close to exit.

9

As required, complete other L2 provisioning (for example, virtual switch, vlan, spanning tree groups, cross-connections) using the procedures in this chapter.

10

A default port tag (Virtual LAN tagging mode Transparent) or default VLAN (Virtual LAN tagging mode 802.1 Tag) must be provisioned for the LAG group in order to pass any untagged frames.

Perform one of the following as required:

  • Virtual LAN tagging mode — 802.1 Tag: Use the TL1 ent-vlan command or Configuration → Data → Create VLAN command from the System View menu to create the default VLAN for untagged traffic for the selected LAG group.

  • Virtual LAN tagging mode — Transparent: Use the TL1 ed-eport command or Configuration → Data → Create Port Tag command from the System View menu to create the default Port Tag for untagged traffic for the selected LAG group.
