Configuring The Mapping Between A Super Vlan And Sub Vlans; Configuring Super Vlan To Support Dhcp Relay - H3C S7500 Series Operation Manual

Operation Manual – Extended VLAN Application
H3C S7500 Series Ethernet Switches
Caution:
The port command is only used to add the Access ports to a sub VLAN. If you want to
add a Trunk port or a Hybrid port to a sub VLAN, you need to execute the port trunk
permit vlan command and the port hybrid vlan command in Ethernet port view. Refer
to the Port part of the manual.
Note that you can add multiple ports (except the uplink port) for a sub VLAN.

3.2.4 Configuring the Mapping between a Super VLAN and Sub VLANs

Follow these steps to configure the mapping between a super VLAN and sub VLAN(s):
Enter system view
Enter VLAN view of the super VLAN
Establish the mapping between the
super VLAN and sub VLAN(s)
Caution:
The sub VLANs must exist before you create mapping between the sub VLANs and
the super VLAN.
When you establish mapping between the super VLAN and the sub VLANs, if a
VLAN interface is configured for the sub VLAN, the system will prompt you to delete
the interface to establish the mapping successfully.
After establishing the mapping between the sub VLANs and the super VLAN, you
can still add (or remove) ports to (from) the sub VLANs.
The system allows for up to 1024 sub VLANs.

3.2.5 Configuring Super VLAN to Support DHCP Relay

With DHCP relay function enabled on the VLAN interface of the super VLAN, the hosts
of all sub VLANs that map with the super VLAN can dynamically obtain IP addresses
from the outside networks.
With the DHCP relay function enabled on the VLAN interface of the super VLAN, the
hosts of the sub VLANs that map the interface and the DHCP server in another network
