DHCP VLAN This setting has no effect on DHCP packets that come from VLANs
where the IES-1248-51V’s DHCP relay settings are active. (See
Chapter 28 on page 217. The DHCP relay settings take precedence
over the IP bridge DHCP VLAN setting.)
Select the VLAN where the domain’s DHCP server is located. If you
select a specific VLAN, the IES-1248-51V forwards subscribers’ DHCP
packets to the selected VLAN and changes the source MAC address to
the IES-1248-51V’s MAC address. Select Disabled if there is no DHCP
server for the domain, in which case the IES-1248-51V does not
change the source MAC address in DHCP packets.
Regardless of this setting, the IES-1248-51V still adds whatever
Option 82 information is specified for the VLAN in the DHCP relay
settings. (See Chapter 28 on page 217.)
Apply Click Apply to save the domain settings.
Clicking Apply 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.
Cancel Click Cancel to start configuring the screen again.
Index This field displays the index number of the VLAN in the domain.
VLAN ID This field displays the ID of each VLAN in the domain.

it from the domain.
