Interface IP
NetMask
Enter the IP address and the number of bits in the subnet mask that define the
range of IP addresses to which this downlink interface applies. If the destination
IP address of a packet is in this range, the IES-1248 tries to forward the frame to
a subscriber in the specified VLAN or PVC. Downlink interfaces in the same
domain cannot have overlapping IP addresses.
VID Enter the VLAN ID the subscriber is in. The IES-1248 uses this VLAN ID when it
forwards frames to the subscriber. It also uses the VLAN ID to identify the
domain the downlink interface is in. You have to add the VLAN ID to an IP
bridge domain before you can enter it here.
Port Select the check box next to this field if you want the IES-1248 to forward
frames to a specific channel in the specified VLAN. Use this drop-down list box
to select the port for the channel.
Note: Make sure you specify a valid IP bridge PVC. Do not
specify PVCs that are not defined in the IPB PVC screen in
Section 39.2 on page 263.
VPI This field is enabled if the check box next to Port is selected. Type the Virtual
Path Identifier for a channel on this port.
VCI This field is enabled if the check box next to Port is selected. Type the Virtual
Circuit Identifier for a channel on this port.
Add Click Add to create the downlink interface. It is then displayed in the summary
table at the bottom of the screen.
Clicking Add saves your changes to the IES-1248’s volatile memory. The IES-
1248 loses these changes if it is turned off or loses power, so use the Config
Save link on the navigation panel to save your changes to the non-volatile
memory when you are done configuring.

Click this to look at all the forwarding information for downstream traffic, whether
learned by snooping DHCP packets or provided manually. (See Section 39.5.1
on page 271.)
The bottom section displays downlink interfaces created manually. It does not show forwarding
information learned by snooping DHCP packets.
Index This field displays the index number of the downlink interface.
Interface IP
NetMask
This field displays the IP address and the number of bits in the subnet mask that
define the range of IP addresses to which this downlink interface applies. If the
destination IP address of a packet is in this range, the IES-1248 tries to forward
the frame to a subscriber in the specified VLAN and PVC, if any.
VID This field displays the VLAN ID the subscriber is in.
Port This field displays the number of the ADSL port to which the IES-1248 forwards
frames. It displays “-” if the IES-1248 looks for the subscriber in the whole VLAN
and not a specific PVC.
VPI/VCI This field displays the Virtual Path Identifier (VPI) and Virtual Circuit Identifier
(VCI), if any. The VPI and VCI identify a channel on this port.
