Layer 2 (L2) Switch
Parameter
Description
Default Value
Voice VLAN ID
System-generated, protected field. Shows voice VLAN ID from the System IP Properties form.
Tag VLAN 1 on Trunk Ports
Select Enabled to enable 802.1p/Q VLAN tagging for VLAN 1 on the 10/100/1GB Base-T LAN port). Enable this parameter only if a VLAN-capable expansion switch is connected to the port.
Notes:
This field applies to untagged and VLAN 1 tagged packets only; voice VLAN tagging is always preserved.
Normally, only one VLAN is required, the default VLAN 1, which carries both voice and data traffic. Optionally, the system can be programmed to support a Voice VLAN in addition to the default VLAN. Voice packets from Mitel IP Phones can belong to either the default VLAN or the Voice VLAN.
Disabled (all VLAN tags are removed before being forwarded by the switch).
IGMP Snooping
Select Disabled to disable the IGMP Snooping functionality. IGMP Snooping allows the switch to automatically pass multicast packets to devices that have joined multicast groups. Without this capability, the switch must forward multicast packets to all ports which results in unnecessary overhead traffic on those non-member ports.
Note: IGMP Snooping interferes with the port-mirroring (sniffer) feature. If IGMP Snooping is enabled and port mirroring is subsequently enabled, IGMP will be automatically disabled while port mirroring is in use. When port mirroring is disabled, IGMP will be re-enabled.
Enabled
Data VLAN ID
(CXi and CXi II only)
System-generated, protected field. Shows the data VLAN ID from the System IP Properties form.
L2 Ports
Port
System-generated, protected field. Indicates the number of the port. The default database has 17 entries with default values for the CXi and two entries for the MXe and MXe Server. The first 16 entries for the CXi and CXi II are for the powered 10/100Base-T/TX LAN ports. The 17th entry for the CXi/CXi II and the two for the MXe and MXe Server are for the unpowered 10/100/1GB Base-T LAN ports.
State
Select Disabled to disable the port.
Enabled
Speed
Select the operating speed of the port. Options include Auto (auto-negotiate), 10 Mb, and 100 Mb. For 1000 Mb (Gigabit) speed operation on the 10/100/1GB Base-T LAN port), set the speed to Auto, and it will auto-negotiate for the gigabit speed. Manually select a speed only if auto-negotiation fails.
Auto
Duplex Mode
Select the duplex mode of the port. Alternative to the default setting, you can select "Full DX" (simultaneous transmission in both directions) or "Half DX" (transmission in both directions, but only in one direction at a time). Manually select the duplex mode only if auto-negotiation fails.
Auto. (Duplex mode is negotiated between the two end points automatically.)
Flow Control
Select the flow control mode of the port. The default is "Auto"; the port will attempt to negotiate flow control with the other end. Alternatively, you can select "Enabled" (forces the port to use flow control) or "Disabled" (disables flow control on the port). Manually select flow control only if auto-negotiation fails.
Power over Ethernet
Applies to the CXi and CXi II only. Select Disabled to disable Power over Ethernet (PoE) for the port. PoE can be left enabled even if the connected device does not require PoE support.
Notes:
This setting is not applicable to port 17.
There is a slight delay before configuration updates take effect within the IP Network forms.
Auto. (Enabled for ports 1-16).
Voice VLAN
Select whether the port is a member of the Voice
VLAN configured in the System IP Properties
form by choosing one of the following options:
Tagged: Tag frames on egress
Untagged: Untag frames on egress
No: Not a member of this VLAN
Note: On ingress, any untagged frames are assigned to the designated untagged VLAN (if one is specified in the System IP Properties form).
Tagged
Data VLAN ID
(CXi and CXi
II only)
As per the Voice VLAN ID field but applies to the CXi and CXi II Data VLAN.
