Advertise Ctrl -
This is the Selective Advertising feature. Selective Advertising is used in
combination with Auto-Negotiation to advertise your selected speed and duplex mode for the
DATA and EXT MGMT ports. This allows you to advertise: all speeds and duplex modes; 10
Mbps Half-Duplex; 10 Mbps Full-Duplex; 100 Mbps Half-Duplex; 100 Mbps Full-Duplex; 10
Mbps Half and Full-Duplex; etc. You must enable Auto-Negotiation for Selective Advertising
to work.
NOTE: When specific speeds and/or duplex modes are desired, Black Box recommends using
Selective Advertising, instead of Force Mode, when connecting to devices that can only auto-
negotiate.
Advertise FlowC and Force FlowCtrl -
These are the Flow Control features.
When you are using Flow Control functionality on any port, you must enable Flow Control
(refer to
Unit Flow Control
for more information). Then configure each port individually:
•
To use Auto-Negotiation and Flow Control:
Advertise FlowC = Advertise Flow, Force FlowCtrl = Flow Auto.
•
To use Auto-Negotiation but not Flow Control
Advertise FlowC = No Flow.
•
To use Flow Control and force the port speed (Port Speed Ctrl)
Advertise FlowC = Advertise Flow, Force FlowCtrl = Frc FlowCt.
All RJ-45 ports feature Flow Control in Full-Duplex and Back Pressure Flow control in Half-
Duplex.
Unit FlowControl -
This allows you to enable or disable Flow Control functionality on the
unit. You must enable this to use Flow Control on any port.
Transparent Mode
The Managed Media Converter can be configured to allow several combinations of VLAN
tagging and management. This manual refers to the most useful combinations as “modes.”
These modes include the following:
•
Default (for initial setup purposes only)
•
Transparent with Untagged Management
•
Transparent with Tagged Management
•
Transparent with Extra Tagging (Q-in-Q)
•
Port VLAN
•
VLAN Filtering
The application of these modes is described in detail in the
Application Examples
section.
NOTE: Default mode is the factory default and is provided as a starting point from which to
configure the Managed Media Converter modules. This mode does not provide adequate
management isolation and is not recommended for normal use.
This section describes the telnet/serial port screens and fields available for configuring the
Managed Media Converter modes.
29
In the above example, management traffic will only pass between the OPTICS (or UPLINK)
port and the EXT MGMT port regardless of the DIP switch settings.
WARNING
Do not leave the Management Vlan VLAN IDs field defined as zero (0). This will disable
management traffic on the Managed Media Converter. You must enter a VLAN ID
between 1 and 4094 (excluding the VLAN IDs used for the Port VLAN or for the Data
VLANs).
Do not use this Management Vlan VLAN ID field when no other VLAN modes are
defined (Transparent mode). This may result in unwanted behavior.
Port VLAN Filter
This parameter allows you to pass traffic with up to 32 separate VLAN IDs between the
OPTICS (or UPLINK) port and the DATA port. To enable the Data Vlans fields, you must
enter Y in the Tags column for both the Optics and Data rows. Enter up to 32 VLAN IDs in
the Data Vlans fields.
