SMI-1110-SFP Managed 10/100/1000 SFP Media Converter Features

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.
SFP Speed Sensing Automatically detects whether a gigabit or Fast Ethernet fiber SFP has been inserted and adjusts accordingly.
Configuration Mode selection Select whether to use the on-board DIP switches or the management software for mode selection
Auto-MDIX Can manually set Auto or MDIX on the copper port via on-board strap or via the management software. 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.

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 a 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.

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 Capable of performing a loopback on the 1000Base-X fiber interface.

Auto-Negotiation (802.3u) Enabled (Default) – The media converter uses 802.3u Auto-negotiation on the 10/100/1000Base-T interface. It is set to advertise full duplex, half duplex, pause and remote fault capabilities.

Disabled – The media converter sets the port according to the position of the speed and duplex switches.

Link Mode Link Mode provides a transparency to the state of the copper link allowing for simplified trouble shooting from the devices connected to the media converter.

Normal (Default – Up)
With Fiber Auto Negotiation enabled when the copper link goes down the 1000Base-X link is brought down. The 1000Base-X link will advertise Remote Fault (Link Fault).

With Fiber Auto Negotiation disabled the state of the copper link has no effect on the 1000Base-X link.

Smart Link Pass Through (Down)
With Fiber Auto Negotiation enabled the behavior is as follows. When the copper link goes down the 1000Base-X link is brought down. The 1000Base-X link will advertise Remote Fault (Link Fault). When Remote Fault (Link Fault) is received on the 1000Base-X interface the copper transmitter will be turned off. When the copper receiver is off the 1000Base-X transmitter will be turned off. When the 1000Base-X receiver goes off the copper transmitter will be turned off.

With Fiber Auto-Negotiation disabled the behavior is as follows. When the copper receiver is off the 1000Base-X transmitter will be turned off. When the 1000Base-X receiver goes off the copper transmitter will be turned off.

Fiber Fault Alert The Fiber Fault Alert switch has meaning when Auto-Negotiation is disabled

Enabled (Default – Up)
When the 1000Base-X receiver is off the 1000Base-X transmitter is turned off. Periodically the 1000Base-X receiver will be turned on for a short period to allow the condition to clear if the 1000Base-X link partner is using a similar feature.

Disabled (Down)

Remote Loopback The media converter can perform a loopback on the 1000Base-X fiber interface.

Disabled (Default – Up)

Enabled – The 1000Base-X receiver is looped to the 1000Base-X transmitter. The copper transmitter is taken off the interface.

Auto-MDIX (Strap) If Auto-Negotiation (802.3u) is enabled, the media converter determines the current cable pinout to use on the copper interface. If Auto-Negotiation (802.3u) is disabled the Media converter will use the RX Energy method on the copper interface to set the port MDI or MDIX whichever is appropriate.

Enabled (Default) – Either a straight-through or crossover type cable can be used to connect the media converter to the device on the other end of the cable.

Disabled – If the partner device on the other end of the cable does not have the Auto-MDIX feature a specific cable, either a straight-through or crossover will be required to ensure that the media converter’s transmitter and the partner devices transmitter are connected to the others receiver. The Media converter’s 100Base-TX port is configured as MDI-X with this switch setting.
