The following table describes the labels in this screen.
Table 123
IPB Interface
LABEL DESCRIPTION
Use the top section to create downlink interfaces manually.
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 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.
VID 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.
PVC, Slot, Port 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 9.19 on page 273 .
VPI/VCI 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.
Apply 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.
New Click New to set the screen to configure a new entry.
Cancel 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.
Index This field displays the index number of the downlink interface.
Domain This field displays the name of the domain to which the edge router belongs.
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 MSC 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.
