IPB Domain
LABEL DESCRIPTION
Name Enter the name of the domain you want to create. You can use 1-31 printable English
keyboard characters, except for right angle brackets (>). Spaces are not allowed.
DHCP VLAN Select the VLAN where the domain’s DHCP server is located. If you select a specific VLAN, the
MSC forwards subscribers’ DHCP packets to the selected VLAN and changes the source MAC
address to the MSC’s MAC address. Select
Disabled if there is no DHCP server for the
domain, in which case the MSC does not change the source MAC address in DHCP packets.
This setting has no effect on DHCP packets that come from VLANs where the MSC’s DHCP
relay settings are active. See
Chapter 15 on page 591 . The DHCP relay settings take
precedence over the IP bridge DHCP VLAN setting. The MSC also still adds whatever Option 82
information is specified for the VLAN in the DHCP relay settings.
Apply Click Apply to create the domain. 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.
Add VLAN Enter the ID of the VLAN you want to add to the domain.

your changes to the non-volatile memory when you are done configuring.
