Installing External Layer 2 Switches - Mitel 3300 Technician's Handbook

3300 ICP Technician's Handbook
on the default VLAN (1), and make sure that it treats packets with
priority 6 as the highest priority. If another VLAN-capable switch is
connected to the first, program it with the same settings.
- On the CXi/CXi II, enable VLAN tagging on the 10/100/1G (port 17)
- On the MXe enable VLAN tagging on both of the 10/100/1G ports.
VLAN tagging is accomplished with the same setting in the ESM Layer
2 (L2) Switch form, "Tag VLAN 1 on Trunk Ports". This setup allows the
VLAN-capable switches to provide the same VLAN prioritization
services as the internal Layer 2 switch on the CXi/CXi II, the MXe and
the AX.
• Router
- If a router is connected to the local internal network, designate it as
the default gateway to the other networks. Program its IP address
as the System Gateway IP on the CXi/CXi II and MXe. If an
external router is present on the LAN, disable the Router Discovery
Protocol on the CXi/CXi II and MXe.

Installing External Layer 2 Switches

Voice Only Networks
The CXi/CXi II provides 16 integrated Ethernet ports that can support up
to 16 IP phones. To increase line size of the CXi to 100 lines (the system
maximum for a CXi/CXi II), connect up to two layer 2 switches.
As a minimum, the L2 switches should support 10/100 BaseT. Because
some programming may be necessary (e.g. port speeds), the L2 switches
require a management interface.
Guidelines:
• When installing the CXi/CXi II, connect a single expansion Layer 2
switch to the 10/100/1G LAN port only. If using two 24-port switches,
connect the second switch to the first in a daisy chain. Do not connect
expansion switches to the 10/100 802.3af LAN ports on the CXi/CXi II.
• Mitel telephones require power, which they can receive from an
adapter or power brick, or from a powered Ethernet connection. The
10/100 802.3af LAN ports of the CXi/CXi II provide Power over
Ethernet (PoE), as do some expansion switches. The 10/ 100/1G LAN
port on the CXi/CXi II does not provide PoE.
