IP-Less Management in HOST/REMOTE configurations
A proprietary, secure management communication channel is supported whenever
the Giga-AccessEtherLinX-II unit is connected directly to an iMcV-GigaFiberLinX-II
unit over the Fiber Uplink. This secure communication channel does not require any
pre-configuration or IP address assignment. It automatically establishes an integrated
Host-Remote management connection between these units, allowing them to be
managed as a single unit, as long as the iMcV-Giga-FiberLinX-II unit is set to a unit via
the DIP Switch setting.

Priority Queuing and Flow Control
The unit supports two different priority queuing schemes. In all modes that do not
allow frame qualification, Priority Queuing is set globally for all ports as a Unit
Control Setting. For modes supporting Qualification, high priority is set individually
per port by the Qualification setting. Frames qualified as high priority will be given
preference over low priority frames to egress the unit.

preference over low priority frames to egress the unit.
When internal congestion occurs and the unit is low on internal buffer space, only
high priority frames will be allowed to enter the unit. If Flow Control is enabled,
PAUSE frames will be sent to all ports causing the congestion. If PAUSE frames are
received on a port, that port will not transmit frames until the PAUSE condition has
expired.

Auto Negotiation, Duplex Mode and Speed
The twisted pair ports on the Giga-AccessEtherLinX-II Auto Negotiate for speed and
duplex mode. This device can also selectively advertise or force the speed and
duplex mode. If the device has a fiber Uplink port, it always operates at 1000 Mbps
full-duplex and supports Auto Negotiation on the fiber segment.

Forcing the Speed and Duplex Mode
The twisted pair Downlink Ports on the Giga-AccessEtherLinX-II can also be manually
set for 10, 100, or 1000 Mbps operation and for half- or full-duplex mode (note:
1000 Mbps only supported in full duplex).

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 mode is desired, use Selective Advertising, rather
than a Force Mode, when connecting to devices that ONLY auto negotiate.

Bandwidth Control
The Giga-AccessEtherLinX-II includes bandwidth control functionality. A maximum
bandwidth can be set independently on each port for both receive and transmit
directions.
