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.
