Port Select the check box next to this field if you want the IES-1248-51V 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 38.2 on page 278.

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-1248-51V’s volatile

memory. The IES-1248-51V 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.

Show Current

Interfaces

Click this to look at all the forwarding information for downstream

traffic, whether learned by snooping DHCP packets or provided

manually. (See Section 38.5.1 on page 288.)

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-1248-51V 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-

1248-51V forwards frames. It displays “-” if the IES-1248-51V 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.
