4.1.2 Full duplex Ethernet
The IP 400 Ethernet controller can be set to full-duplex operating mode. Normally
the IP 400 is operated in half-duplex mode.
For full-duplex operation:
• Go to
IP Interfaces > Ethernet Interface
in the configuration applet.
• Check
Full duplex
on the
Ethernet Interface
form.
• Set your Ethernet switch to always run in full duplex mode, for the port to
which the IP 400 is connected. This is necessary, as the operating mode of
the IP 400 is not negotiated. Faults will occur if the IP 400 settings do not
correspond to those of the Ethernet switch.
4.1.3 Priority on Ethernet
The Ethernet packets sent by the equipment can be prioritised, at level 2, in the
switch. To do this, the packets must be marked accordingly, during transmission.
This function must be supported by the switch used.
• Select
IP Interfaces > Ethernet Interface
in the configuration applet.
• Tick
Use 802.1p for Quality of Service
to mark the packets sent with
VLAN ID 0 and priority 7.
• The VLAN ID with the value 0 switches QoS off, following 802.1Q. The value 0
is assumed if the
802.1 Q VLAN ID
field is empty. If your switch port, con-
nected to the innovaphone gateway, is configured to a different VLAN ID, you
have to use the same value here, to enable the prioritisation of the Ethernet
packets.
innovaphone equipment can access the VLAN ID and the VLAN priority using
DHCP. See Appendix D: “The innovaphone DHCP Client” from page 152 for more
information on the DHCP client, the VLAN ID and the VLAN priority.
Caution
Note the configuration of the switch, before setting the
VLAN ID
.
