This setting has no effect on DHCP packets that come from VLANs where the system’s DHCP relay
settings are active. (See Chapter 19 on page 647. The DHCP relay settings take precedence over

This command specifies the VLAN where the domain’s DHCP server is located. The VLAN must
already be in the domain. The MSC forwards subscribers’ DHCP packets to the selected VLAN and
changes the source MAC address to the MSC’s MAC address.
The MSC still adds whatever Option 82 information is specified for the VLAN in the DHCP relay
settings. (See Chapter 19 on page 647.)
In the following example, domain “example3” has its DHCP server in VLAN 401.
