CLI Commands
4.9 I
● Local, L2 — In this mode, the virtual controller acts as a DHCP server with data center as
the gateway. When Local, L2 DHCP scope is selected, the network address translation
for client IPs is not carried out at the source.
● Local, L3 — In this mode, the Virtual Controller acts as a DHCP server and the gateway,
and assigns an IP address from the local subnet. The AP routes the packets sent by
clients on its uplink. This mode does not provide corporate access through the IPsec
tunnel. This DHCP assignment mode is used with the L3 forwarding mode.
● Centralized, L2 — When a Centralized, L2 DHCP scope is configured, the Virtual
Controller bridges the DHCP traffic to the controller over the VPN/GRE tunnel. The IP
address is obtained from the DHCP server behind the controller serving the VLAN/GRE
of the client. This DHCP assignment mode also allows you to add the DHCP option 82 to
the DHCP traffic forwarded to the controller.
● Centralized, L3 — For Centralized, L3 clients, the Virtual Controller acts as a DHCP relay
agent that forwards the DHCP traffic to the DHCP server located either in the corporate
or local network. The centralized L3 VLAN IP is used as the source IP. The IP address is
obtained from the DHCP server.
Example
The following example configures a Distributed, L2 DHCP scope:
(scalance)(config)# ip dhcp corpNetwork1
(scalance)(DHCP Profile"corpNetwork1")# ip dhcp server-type distributed,l2
(scalance)(DHCP Profile"corpNetwork1")# server-vlan 1
(scalance)(DHCP Profile"corpNetwork1")# subnet 192.0.1.0
(scalance)(DHCP Profile"corpNetwork1")# subnet-mask 255.255.255.0
(scalance)(DHCP Profile"corpNetwork1")# default-router 192.0.1.1
(scalance)(DHCP Profile"corpNetwork1")# client-count 0
(scalance)(DHCP Profile"corpNetwork1")# dns-server 192.0.1.2
(scalance)(DHCP Profile"corpNetwork1")# domain-name www.example.com
(scalance)(DHCP Profile"corpNetwork1")# lease-time 1200
(scalance)(DHCP Profile"corpNetwork1")# ip-range 192.0.1.0 192.0.1.17
(scalance)(DHCP Profile"corpNetwork1")# reserve first 2
(scalance)(DHCP Profile"corpNetwork1")# option 176
"MCIPADD=10.72.80.34,MCPORT=1719,TFTPSRVR=10.80.0.5,L2Q=1,L2QVLAN=2,L2QAUD=5,L2QSIG=3
"
(scalance)(DHCP Profile"corpNetwork1")# end
(scalance)# commit apply
The following example configures a Distributed,L3 DHCP scope:
(scalance)(DHCP Profile <profile-name>)# ip dhcp server-type <Distributed,L3>
(scalance)(DHCP Profile <profile-name>)# server-vlan <vlan-ID>
(scalance)(DHCP Profile <profile-name>)# client-count <number>
