Disable Duplicate STE

This option disables the creation of duplicate frames present in mixed bridging environments. When the SR-TB bridging feature is enabled on an 802.5 interface (with source routing and transparent bridging enabled), there are inconsistencies created when bridging frames to an unknown (or multicast) destination. It is not known to the bridge whether the destination is behind a source routing (only) or transparent bridge.

To remedy this situation, the bridge sends out duplicates of these frames (by default). One frame has source routing fields present (a spanning tree explorer RIF) and the other is formatted for transparent bridging (no RIF is present). Normally, you would want both types of frames sent out when in a mixed bridging environment.

However, if you do not want both frame types, Disable duplicate STE lets you eliminate this duplication by disabling the creation of STE frames. In this case, the bridge sends only Transparent Spanning Frames (TSFs) for the transparent bridging environment.

Enter the port number that should not generate STE frames.

Select the Submit button.


Disable Duplicate TSF

Disables the creation of duplicate frames present in mixed bridging environments. When the SR-TB bridging feature is enabled on an 802.5 interface (with source routing and transparent bridging enabled), there are inconsistencies created when bridging frames to an unknown (or multicast) destination. It is not known to the bridge whether the destination is behind a source routing (only) or transparent bridge.

To remedy this situation, the bridge sends out duplicates of these frames (by default). One frame has source routing fields present (a spanning tree explorer RIF) and the other is formatted for transparent bridging (no RIF is present). Normally, you would want both types of frames sent out when in a mixed bridging environment.

However, if you do not want both frame types, Disable duplicate TSF lets you eliminate this duplication by allowing you to disable the creation of TSFs. In this case, the bridge sends only STE frames for the source route bridging environment.

Enter the port number that should not generate TSF frames.

Select the Submit button.


Disable Ethertype-IBMRT-PD

This option disables translation of SNA frames to Ethernet Type 2 format as used by IBM RTs running OS/2 EE.

Enter the port number to which this disable option applies.

Select the Submit button.


Disable Spanning-Tree-Explorer

Select the Submit button.


Enable Ethertype-IBMRT-PD

This option enables translation of SNA frames to Ethernet Type 2 as used by IBM PC RTs running OS/2 EE. Using this option will result in SNA frames being duplicated into both 802.3/802.2 and IBM-RT formats to unknown hosts on an Ethernet.

Enter the port number that should have this translation enabled.

Select the Submit button.


Enable Spanning-Tree-Explorer

This option enables the port to allow propagation of spanning tree explorer frames if source routing is enabled. This is valid on token-ring ports only. This feature is enabled by default when source routing is configured on the port.

Enter the port number that should propagate STE frames.

Select the Submit button.


Enable Source Routing

This option enables source routing for a given port. This option is typically used when source routing on part of the bridge is desired. If source routing is the only feature desired, transparent bridging on the interface should be disabled.

The bridge number must be entered only in the first Enable Source-Routing command. If you enter the bridge number on subsequent Enable Source-Routing commands, it will be ignored.

Enter the following information:

  1. Enter the Port Number of a valid port participating in the bridge configuration.

  2. Enter the Segment Number that is used to represent the entire transparent (Ethernet) bridging domain. This number is required to enable the bridge to convert source-routed frames to transparent frames and transparent frames to source-routed frames.

    Source routing to transparent bridging conversion must be enabled.

    Valid Values: X'0' to X'FFF'

    Default Value: 1

    Select the Submit button.

  3. Enter the Bridge Number that is unique among all the bridges attached to the same LAN.

    This value is required when source routing is enabled on the first interface. For later interfaces, this input is optional. The bridge number is used to construct and inspect the Source-Route RI field.

    Valid Values: X'0' to X'F'

    Default Value: 1

Select the Submit button.


Enable SR-TB Conversion

This parameter enables the conversion of a source-routed frame to a transparent frame and vice-versa.

This conversion allows for compatibility between Source Routing and Transparent Bridging domains. When this feature is enabled, the bridge lets source-routed frames be accepted into a transparent domain by stripping off the router information field (RIF) and converting them into transparent frames.

The bridge also gathers routing information concerning source routing stations from the passing source-routing frames. This is obtained from the RIF. This RIF information is then used to convert a transparent frame to a source-routed frame. If a RIF is not available for a station, then the frame is sent out as a spanning tree explorer frame in the source routing domain.

In order for the conversion function to operate properly, the transparent bridging domain must be given a segment number. All SR-TB bridges that are connected to this domain should also be configured with the same segment number.

  1. Enter the (Transparent Bridge) TB-Domain Segment Number.

    This parameter specifies the number, in 4-digit hexadecimal, that represents the LAN to which the media is attached. All the media on other bridges attached to this LAN must be configured with the same value for source routing to operate correctly.

    Valid Values: X'1' - X'FFF'

    Default Value: 1

  2. Enter the TB-Domain's MTU (in bytes).

    The maximum transmission unit (MTU) is the number of octets per frame of data that can be transferred across a given physical network. When an IP datagram travels from one host to another, it can cross different physical networks. Some physical networks may have this set MTU which will not allow long IP datagrams to be placed in on physical frame. Fragmentation will occur when you attempt to transmit frames larger than that which the physical network can handle.

    Valid Values: 576 to 18000 bytes

    Default Value: 2048
