MXe Server/MXe/AX/CXi/CXi II Requirements for IP
Networking
LAN Requirements
• A subnet with IP addresses reserved for the following:
- the MXe Server/MXe/AX/CXi/CXi II system
- the internal Layer 2 switch
- the system gateway (router on the LAN or the controller itself)
- static IP addresses or DHCP-assigned addresses for IP phones
(DHCP-assigned addressing is recommended).
• A Dynamic Host Configuration Protocol (DHCP) server within the
Broadcast Domain. The CXi, CXi II, and MXe include a DHCP server.
• Optional:
- a router or firewall on the same subnet as the controller. (Note that
firewall (including NAT) is on by default for incoming connectivity
from the Internet via the WAN port.)
- external Layer 2 switches (unmanaged for a voice only; managed
and VLAN-capable for a voice and data implementation). The CXi
and CXi II supports as many switches as are required but you
cannot exceed the maximum of 100 IP users.
- SMTP server address to support e-mail forwarding
- DNS server address; external DHCP server information;
- one PC per IP phone (phones must be dual-port models); PCs
must have 10/100BaseTx Ethernet cards.
Tip: IP phones/IP devices should only be served by one DHCP server.
Tip: Layer 2 switches should only be connected to Port 17 on the CXi and
CXi II, the left Gigabit port on the CX, CX II, MXe and MXe Server. This rule
lessens the chance of spanning tree issues (loops in the network). Either
port will work when connecting to the AX.
Tip: IP trunks cannot work through the WAN port.
