DESCRIPTION
Use the top section to create downlink interfaces manually.
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 MSC 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.
Enter the VLAN ID the subscriber is in. The MSC 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.
Select the PVC check box if you want the MSC to forward frames to a specific
channel in the specified VLAN. Use the Slot and Port drop-down list boxes to
select the line card and port for the channel.
Note: Make sure you specify a valid IP bridge PVC. Do not
specify PVCs that are not defined in the IPBPVC screen in
Section 11.19 on page
These fields apply if you select the PVC check box. Type the Virtual Path
Identifier and Virtual Circuit Identifier for a channel on this port.
Click Apply to create the downlink interface. It is then displayed in the summary
table at the bottom of the screen.
Clicking Apply saves your changes to the MSC's volatile memory. The MSC
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 New to set the screen to configure a new entry.
Click Cancel to start configuring this section of the screen again.
The bottom section displays downlink interfaces created manually. It does not
show forwarding information learned by snooping DHCP packets.
This field displays the index number of the downlink interface.
This field displays the name of the domain to which the edge router belongs.
