SELECTIVE ADVERTISING
Selective Advertising, when used in combination with Auto Negotiation,
advertises only the configured speed and duplex mode for the twisted-pair port. If
a specific speed and/or duplex are desired, B+B SmartWorx recommends using
Selective Advertising(rather than Force Mode) when connecting to devices that
only use Auto Negotiation.
BANDW IDTH CONTROL
The iMcV-Giga-FiberLinX-III includes bi-directional bandwidth control
(configurable via iView
2
). This allows the bandwidth limit to be set independently
from the DATA Port to the OPTICS (or UPLINK) Port and vice versa in a single
iMcV-Giga-FiberLinX-III application. In a Host/Remote iMcV-Giga-FiberLinX-III
application, it can be set from the Host unit to the Remote unit and vice versa
(i.e., bandwidth on the DATA ports on both the Host and Remote modules can be
limited independently).
LINK FAULT PASS THROUGH (LFPT)
Link Fault Pass-Through (LFPT) is a diagnostic feature that can be enabled or
disabled. When enabled, it allows the end-user to visually detect that the Link
and the LNK LEDS will extinguish on the front faceplate of the module, when a
fault occurs. LFPT can be enabled through the SNMP software (iView²) or
serial/Telnet.
The iMcV-Giga-FiberLinX-III has three ports: Data, Optics and Ext Management.
LFPT can be enabled between any two ports. For example, if LFPT is configured
as “from” the Optics port “to” the Data port, when a fault occurs on the Optics
port,
both LEDs for those ports will extinguish. The end-user can decide which
port he wants the fault to be reported to, based on which port he wants to be in
control. LFPT allows the fault to be reported down the line, through to the link
partner at the end, such as a switch or a router.
LFPT can be used in addition to setting up SNMP Traps for link up/link down.
LFPT provides a visual way to determine that link is down; and an SNMP Trap
provides a notification of a link down to a designated workstation.
LOOPBACK TESTING
The iMcV-Giga-FiberLinX-III includes Loopback testing functionality. During
loopback testing, management traffic entering the uplink port is still capable of
managing the device. This is selectable form the UNIT screen in a serial/Telnet
session or through iView².
