QOS ( Quality of Service )
|
- Bandwidth Allocation via rate limiting
- IEEE 802.1P tagged frame priority control
- IEEE 802.1P priority tag remapping
- IP TOS ( Type of Service ) priority for IPV4 Diffserv or IPV6 traffic class frames
- Congestion Service Policy through WQF ( Weighted Fair Queuing ) or Strict Priority Queuing ( default )
|
|
VLAN Tagging
|
- Default – Transparent to VLAN frames
- Enable discarding of tagged frames
- Enable discarding of untagged frames
- Untag – Removes any existing tag
- Insert Tag – Insert (if original
frame is untagged) or replace (if original frame is tagged) the VLAN ID
and priority with the configured default VLAN ID and priority tag.
- Insert Double tag (Q in Q) – Append an additional tag using the configured default VLAN ID and priority.

|
Unknown Multicast Frame filtering
|
When enabled, Multicast frames with an unknown destination address are not allowed to egress the port
|
|
Unknown Unicast Frame filtering
|
When enabled, Unicast frames with an unknown destination address are not allowed to egress the port
|
|
Unidirectional Ethernet
|
When enabled, provides the ability to
restrict port to one-way traffic flow. Used in applications such as
unidirectional video broadcasting as well as providing security for
ethernet connections in accessible public areas
|
|
Configuration Mode selection
|
Select whether the module is to use the on-board DIP switches or enable the management module in the chassis to manage
|
|
Auto-MDIX
|
Can manually set Auto or MDIX on the
copper port via on-board strap or via the management card. Auto-MDIX
(automatic medium-dependant interface crossover) detects the signaling
on the copper ethernet interface to determine the type of cable
connected (straight-through or crossover) and automatically configures
the connection when enabled. The media converter can also correct for
wires swapped within a pair.
The media converter will adjust for up
to 120ns of delay skew between the 1000Base-T pairs.
|
|
Module Information
|
- Chassis slot number that the module is in
- Media converter model and serial number
- User configurable media converter module name
- User configurable fiber port name
- User configurable copper port name
- Copper Downshift status
- Hardware revision number
- Firmware version number

|
Selectable Max Packet Size
|
Set max packet size to 1522 / 2048 or 10,240 ( default )
|
|
10BaseT Extended Distance
|
Normal/extended – default Normal. By
configuring as “extended”, the 10baseT receiver sensitivity is increased
providing the possibility of an 10BaseT connection greater than 100m.
|
|
Auto Copper downshift
|
automatically detects a 2-pair cable
environment and downshifts operation of the link to 100 Mb/s. Configure
the number of times ( 0-8 ) that the PHY will attempt to establish a
successful Gigabit link before attempting to “downshift” as an
auto-negotiating 10/100 device. Setting # of attempts to 0 ( default )
disables the feature.
|
|
Virtual Cable Test
|
A test that enables the detection of
potential copper cabling issues such as pair polarity pair swaps and
excessive pair skew as well as any opens, shorts or any impedance
mismatch. Will report the distance in the cable to the open or short.
|
|
Port Control
|
Enable or disable individual fiber or copper port on the module
|
|

- Fiber Loopback mode (On/Off)
|
|
Module Control
|
- Reset card
- Reset to factory default
- Reset Statistical counters
- Phy specific commands such write/read config, read dip switches
- Update firmware
- Fiber Loopback mode. (On/Off)
- Virtual Cable Test. (On/Off)
- Upload/download configuration
|
|
Backup and Restore
|
Provides fast and easy module
replacement. Management module will always save a copy of the media
converter configuration and will restore this configuration
automatically to the media module when it is detected in the slot
|
|
Detailed port statistics
|
To assist in troubleshooting copper
and fiber links, an extensive list of ingress and egress counters for
both copper and fiber ports are available. These statistics can be
viewed locally via the management module or from a central SNMP NMS on
the network
|
|
Auto-Negotiation (802.3u)
|
The media converter supports auto
negotiation. The 1000Base-X fiber interface negotiates according to
802.3 clause 37. The 10/100/1000Base-T negotiates according to 802.3
clause 28 and 40. The 1000Base-X will link up with its partner after the
highest common denominator (HCD) is reached and the copper has linked
up with its partner. The 1000Base-X will continue to cycle through
negotiation transmitting a remote fault of offline (provided this is
enabled through the switch setting) until the copper is linked up and
the HCDs match.
The media converter supports
auto-negotiation of full duplex, half duplex, remote fault, full duplex
pause, asymmetric pause and Auto MDI-X.
|
|
Smart Link Pass-Through
|
When the Link Mode switch is placed
into Smart Link Pass-Through mode, the copper ethernet port will reflect
the state of the 1000Base-X media converter port. This feature can be
used whether fiber auto-negotiation is enabled or disabled.
|
|
Fiber Fault Alert
|
With Fiber Fault Alert the state of
the 1000Base-X receiver is passed to the 1000Base-X transmitter. This
provides fault notification to the partner device attached to the
1000Base-X interface of the media converter. If the 1000Base-X
transmitter is off as a result of this fault it will be turned on
periodically to allow the condition to clear should the partner device
on the 1000Base-X be using a similar technique. This eliminates the
possibility of lockouts that occur with some media converters. Applies
only when fiber auto-negotiation is disabled.
|
|
Pause (IEEE 802.3xy)
|
Pause signaling is an IEEE feature
that temporarily suspends data transmission between two devices in the
event that one of the devices becomes overwhelmed. The media converter
supports pause negotiation on the 10/100/1000Base-T connection and
1000Base-X fiber connection.
|
|
Duplex
|
Full and half duplex operation supported.
|
|
Jumbo Packets
|
Transparent to jumbo packets up to 10KB.
|
|
Remote Loopback
|
