6-6 Port Setup

Table 6-4 VDSL Edit Port Setup

LABEL DESCRIPTION

Port Number This read-only field displays the port index number you are now configuring.

Name Choose a descriptive name for identification purposes.

Default Priority This priority value is added to incoming frames without a (802.1p) priority tag (this is not the

same as port priority talked about below).

Limiting Number

of MAC Address

Use this field to limit the number of (dynamic) MAC addresses that may be learned on a

VDSL port. For example, if you set this to “5” on port 2, then only the devices with these

five learned MAC addresses may access port 2 at any one time. A sixth device would have

to wait until one of the five learned MAC addresses aged out. MAC-address aging out time

can be set in menu 2. The valid range is from 0 to 254.

Active The factory default of all VDSL ports is disabled. A port must be enabled for data

transmission to occur. Select Active to enable the port.

Type This read-only field displays the type of port you are currently configuring.

Mode VDSL mode can be configured per port. Choose from 10BaseS, ETSI Plan 997,

ANSI/ETSI Plan 998, or Special-mode.

Rate Adaption Select the check box to enable rate adaption.

Up Stream Select the upstream speeds from the drop-down list box. Speeds available depend on the

VDSL mode you select in the Mode field.

Down Stream Select the downstream speeds available for the VDSL mode you select in the Mode field.

Static MAC

Address Filtering

A static MAC address entry is an address that you manually enter into the MAC address

learning table. Static MAC addresses do not age out. This may reduce unicast flooding.

The devices with MAC addresses on this list can only receive traffic on this port on the

VES.

Number This is the ID number of the device entry.

Active Select this check box to turn on static MAC address forwarding for this entry’s MAC

address. The device with this entry’s MAC address can only receive traffic on this port on

the VES.

Clear this check box to turn off static MAC address forwarding for this entry’s MAC

address. The device with this entry’s MAC address can only receive traffic on this port on

the VES.

Static MAC

Address

Enter the MAC address in valid MAC address format, that is six hexadecimal character

pairs.

Spanning Tree

Protocol

Select the check box to use STP on this port.

Priority Configure the priority for each port here. Priority decides which port should be disabled

when more than one port form a loop in a switch. Ports with a higher numeric priority value

are disabled first. The allowed range is between 0 and 255 and the default value is 128.

Path Cost Path cost is the cost of transmitting a frame onto a LAN through that port. It is assigned

according to the speed of the media. The slower the media, the higher the cost.

VLAN These fields are available when you enable IEEE 802.1 VLAN on the VES.

Default VLAN ID Default VLAN ID is the PVID (Port VLAN ID) assigned to untagged frames or priority

frames (0 VID) received on this port.
