Subnet Mask
A subnet allows the flow of network traffic between hosts to be segregated based on a
network configuration.
Gateway IP Address
The IP address of a computer / router on the current network that acts as a gateway.
Use VLAN For Management Interfaces
This controls use of VLAN tags at the management interfaces
(WWW/SNMP/SMTP/SNTP). See LAN configuration page for VLAN on
page 6-45.
Ethernet Auto Negotiation
This enables the Ethernet configuration to be forced rather than auto negotiated.
CAUTION
The IEEE802.3 specification recommends enabling Auto Negotiation. The
configuration should only be forced if you are having problems with auto
negotiation. You must ensure that you configure both this unit and the
Ethernet port to which it is connected identically. If you force a fixed
Ethernet Configuration on the PTP 600 Series then you MUST also force the
same fixed configuration on the equipment to which it is connected. If you
fail to force the configuration of the connected equipment, its automatic
configuration mechanisms will normally cause a duplex mismatch, and you
will receive greatly reduced throughput!
When Ethernet Auto Negotiation is Disabled, the format of the LAN configuration page
changes see LAN Configuration Page – Manual Ethernet Configuration on
page 6-48.
Auto Neg Advertisement
This controls the rates that the auto negotiation mechanism will advertise as available.
CAUTION
Over the air throughput will be capped to the rate of the Ethernet interface
at the receiving end of the link.
Ethernet Auto Mdix
This enables/disables the Auto Medium Dependent Interface (MDI)/Medium Dependent
Interface Crossover (MDIX) capability. Default is “Enabled”.
