Ethernet Port Equipment and Port Configuration
2. To enable the interface, select checkbox Enable. Ports ETH-{1-4} can be configured in
advance (without need to plug Ethernet cable first).
Prior to enable ports ETH-5 and ETH-6, SFP-1-1 and SFP-1-2 modules should be either
plugged (and then auto-configured) or just configured manually, keeping the option of
pre-provisioning.
3. In the SNMP Alias field, enter an identifiable name for the Ethernet link. Range = up to
32 characters. This description is NOT sent along with SNMP messages such as log
information. The same name will appear via TL1 communication and via SNMP
communication, as “ifAlias” OID in IfXTable MIB.
4. Setting port communication Mode. This parameter is not relevant to HSL ports.
The port communication mode is by default defined as Auto-negotiation, where the
speed and duplex mode are automatically recognized. In some cases, such as assigning
the port to a LAG or for 100BaseFX (fiber) ports, it is required to select the speed and
duplex mode. For example, 100M HD refers to 100Mbps Half Duplex mode (in case of
manual setting, set the Pinout MDI option as well).
NOTE: upon insertion of SFP module to the system (and if Auto-configuration is allowed
per system), ETH-5,6 port is automatically configured with: MODE=AUTO, Flow
Control=OFF
5. If Auto-negotiation is NOT selected, decide on Pinout for ETH-{1-4} 10/100BaseT
ports. If auto-negotiation enabled and link is Up, the MDI mode is automatically detected
(Auto-MDIX)). MDI (Medium Dependent Interface) defines cable connector (pinout)
between the signal transceivers and the link. Select as follows:
MDI - Straight connection. Used when connecting to an MDI-X device such as a
switch.
MDI-X - Crossed connection. Used when connecting to an MDI device such as a PC
NIC. Default for Ethernet COLAN port.
If Auto-negotiation is NOT selected, Set the port Flow Control (not relevant to HSL
ports). Select as follows:
OFF – no Flow Control mechanism is applied.
ON – Flow Control mechanism starts work in both TX and RX directions of the port.
Flow Control is used to pause ingress traffic (regardless of frame priority) when the
egress port is congested.
Flow control on RX direction obeys instructions from the opposite port, to slow down
its own port transmit rate.
Flow control on TX direction instructs the opposite port to slow down its transmit
rate.
Flow Control can be established as a part of Auto-negotiation or can be set manually.
NOTE: In manual setting it is important that both ports are configured in the same way
and in the same MODE, as the Flow control applied in HALF-DUPLEX and in FULL-
DUPLEX modes are incompatible.
