Configuring the Cajun P550 Switch (Layer 2 & Layer 3)

 

 

 

 

 

 

 

Table 3-4.Gigabit Port Parameters (Continued)

 

 

 

 

 

 

Parameter

 

Definition

 

 

 

 

 

 

 

Flow Control

 

Determines if IEEE 802.3z pause control is used on this port.

 

 

Mode

 

The pause mechanism allows the port to stop a sending station

 

 

 

 

from sending more packets if the receiving port’s buffers are full.

 

 

 

 

This helps prevent lost or dropped packets.

 

 

 

 

This feature is recommended for use primarily on end station

 

 

 

 

connections. Using this feature on trunk ports can cause

 

 

 

 

unnecessary congestion on the network.

 

 

 

 

 

 

 

Port PACE Priority

 

Determines if the port detects 3Com’s copyrighted PACE format

 

 

 

 

as packets pass through the port. PACE allows a packet’s priority

 

 

 

 

(higher priority packets move through the switch faster) to be

 

 

 

 

set at the adapter.

 

 

 

 

 

 

 

Remote Fault

 

Proprietary mechanism to detect remote link errors on Cajun

 

 

Detect

 

gigabit ports. The default value is Disabled.

 

 

 

 

The remote fault detection functionality should be enabled (on

 

 

 

 

both ends of a Cajun to Cajun link) in two cases:

 

 

 

 

•

When two Cajun gigabit ports are connected that do not

 

 

 

 

 

support auto-negotiation.

 

 

 

 

•

When a Cajun gigabit port that does not support

 

 

 

 

 

auto-negotiation is connected to a Cajun gigabit port that

 

 

 

 

 

does support auto-negotiation.

 

 

 

 

 

 

 

Configuring Physical Port Parameters on Fast Ethernet Ports

To configure ports on a Fast Ethernet module:

1.In the System Configuration section of the Web Agent window, select Modules & Ports. The Module Information dialog box opens.

2.In the Ports column, click the number for the module you want to configure (for example, 12 for 100Base-TX). The Physical Port Configuration dialog box opens.

3.Click the Enable check box to enable a port, or if the check box is enabled, click the Enable check box if you want to disable the port.

4.Click APPLY to save your changes, or CANCEL to restore previous settings.

5.In the Name field, click the port name to set additional parameters. The Detailed Physical Port Configuration dialog box opens.

Refer to Table 3-5 for more information on the Fast Ethernet (10/100) parameters.

6.In the Name field, enter a port name.

7.If this is an end-station port, from the Category pull-down menu, select User Port. For trunk ports, select Service Port.
