Configuring VLACP for specific ports using EDM

Use the following procedure to configure VLACP for a single port or multiple ports.

Procedure steps


Step Action

1

From the navigation tree, double-click Edit.

2

In the Edit tree, double-click Chassis.

3

In the Chassis tree, double-click Ports.

4

Click the VLACP tab.

5

To select a port to edit, click rcPortIndex row.

6

In the port row, double-click the cell in the AdminEnable column.

7

Select a value from the list—true to enable VLACP for the port, or false to disable VLACP for the port.

8

In the port row, double-click the cell in the FastPeriodicTimer column.

9

Type a value in the dialog box.

10

In the port row, double-click the cell in the SlowPeriodicTimer column.

11

Type a value in the dialog box.

12

In the port row, double-click the cell in the Timeout column.

13

Select a value from the list.

14

In the port row, double-click the cell in the TimeoutScale column.

15

Type a value in the dialog box.

16

In the port row, double-click the cell in the EtherType column.

17

Type a value in the dialog box.

18

In the port row, double-click the cell in the EtherMacAddress column.

19

Type a value in the dialog box.

20

You can repeat steps 4 through 19 to configure VLACP for additional ports as required.

21

Click Apply.

Variable Definitions

Use the data in this table to edit the VLACP configuration for individual ports.

Variable Value
rcPortIndex Specifies the switch and port number.
AdminEnable Indicates whether VLACP is enabled (true) or disabled (false) on ports. The default value is disabled.
OperEnable Indicates whether VLACP is operationally enabled or disabled. This is a read-only cell.
Attention

VLACP is only operational when OperEnable is true and PortState is up.

FastPeriodicTimer Specifies the number of milliseconds between periodic transmissions using short timeouts. Valid values range from 400-20000 with a default of 500.
SlowPeriodicTimer Specifies the number of milliseconds between periodic transmissions using long timeouts. Valid values range from 10000-30000 with a default of 30000.
Timeout Specifies whether the timeout control value is a short or long timeout.
TimeoutScale

Specifies the scale value used to calculate timeout from periodic time. Values range from 1–10. The default is 3.

With VLACP, a short interval exists between a port transmitting a VLACPDU and the partner port receiving the same VLACPDU. If the timeout-scale is set to 1, the port timeout value does not take into account the normal travel time of the VLACPDU. The port expects to receive a VLACPDU at the same moment the partner port sends it. Therefore, the delayed VLACPDU results in the link being blocked, and then enabled again when the packet arrives.
Nortel recommends that you set the timeout scale to a value larger than 1.

EtherType Specifies VLACP protocol identification. The value can be entered as a numerical value ranging from 33025–33279 or a hexadecimal equivalent (8101–81ff). The default is 8103. Use the prefix 0x to type a hexadecimal value in the dialog box. Only hexadecimal values display in the EtherType column of the VLACP work area.
EtherMacAddress

Specifies the MAC address of the switch or stack to which a port is sending VLACPDUs. The default value is 00:00:00:00:00:00. It cannot be configured as a multicast MAC.

VLACP uses only the multicast MAC address configured when VLACP is enabled globally. This is the Layer 2 destination address used for the VLACPDUs.
If you do not type a value for the EtherMACAddress, the first VLACP-enabled switch that receives the PDUs from a sending port becomes the intended recipient and processes the PDUs.

If you want an intermediate switch to drop VLACP packets, configure EtherMACAddress with the desired destination MAC address. With EtherMACAddress configured, the intermediate switches do not misinterpret the VLACP packets.

PortState Indicates whether the VLACP port state is up or down. This is a read-only cell.
Attention

VLACP is only operational when OperEnable is true and PortState is up.
