Program the uplink port of the expansion switches to send and receive
tagged packets on the default VLAN (1), and make sure that the expansion
switches treat packets with priority value 6 as highest priority (this is the
default setting on most switches).
Program the CXi/CXi II/MXe/AX to tag packets on their 10/100/1G LAN
port(s).
Note:This assumes that the data VLAN is 1, and this is not always the case.
You have to use untagged native to change this.
Guidelines
1. When connecting an expansion L2 switch to the CXi/CXi II, ensure
that the switch is only connected to the 10/100/1G LAN port. If using
two 24-port switches, connect the second switch to the first in a daisy
chain.
2. When connecting expansion L2 switches to the CXi/CXi II, ensure that
VLAN tagging is enabled on all trunk links that connect the expansion
switches together. For two expansion switches, you need to enable
VLAN tags for VLAN 1 on:
- 10/100/1G LAN port of CXi/CXi II (port 17)
- Switch port on first expansion switch; connects to port 17
- Switch port on first expansion switch; connects to second switch
- Switch port on first expansion switch; connects to first switch.
3. When connecting L2 switches to the MXe or AX, ensure that VLAN
tagging is enabled on all trunk links that are used to connect L2
switches together. Enable VLAN tags for VLAN 1 on the LAN ports of
the MXe/AX and the switch ports on the L2 switches that connect to
the MXe/AX.
4. Connect the port(s) to the highest speed port on the first expansion
switch, preferably a 1G port.
5. By default, all ports of the internal Layer 2 switch are on the default
VLAN (1). This setting cannot be changed except on a CXi running
Release 9.0 or later and on a CXi II.
6. Connect IP devices (PCs) to the voice and data network directly
through a switch or indirectly through a dual-port IP phone. Servers
must be connected to the network directly via a switch.
7. Dual-port phones use the same port speed as the connected PCs. For
this reason, PCs with 100 Mbps Ethernet cards are recommended.
