SDLC sessions are always locally acknowledged. The default is , but that can be overridden with larger values. As part of the SDLLC configuration on the router’s serial interface, the largest frame size the two media will support should be selected. Figure shows a router configuration when the router directly connects the Token Ring and the serial line. In addition, you must perform one of the sets of tasks in the following sections: Task Command Define a ring group.

Enable QLLC local acknowledgment for remote source-route-bridged connections. This is only possible for a device that is attached through a PVC, although most devices that are connected through X.
To configure them, perform the following task in interface configuration mode: The tasks you perform differ somewhat depending on the type of virtual circuit you plan to support on the interface. QLLC conversion can run on ubm router with at least one serial interface configured for X.
Moreover, there is no reassembly on receiving ibj on the X. Specify the largest packet that can be sent or received on the X. To enable QLLC conversion, you must perform the first of the following tasks.
DLSw and Logical Link Control 2 (LLC2)
The same router is configured for translational bridging, which translates Ethernet packets into Token Ring packets and passes them across the WAN to Router B connected to the 3×74 cluster controller via a serial line.
Initiate Connection to Token Ring Host. To define the XID value associated with an X. You can increase the data transfer rate by increasing the SDLC line speed on the serial interface. The following configuration file configures the Router B in Figure To specify the largest packet that can be sent or received on the X.
As part of the SDLLC configuration on the router’s serial interface, the largest frame size the two media will support should be selected. To define XID on the router, perform the following task in interface configuration mode: The Token Ring host is always kept in a state ready to accept a connection from the remote serial device.
A route is then established between the Token Ring host and the router. These represent control block space in the NCP simulating switched line as described earlier.
A router connects the Token Ring network to the X. IDNUM is any five hexidecimal digit combination. In addition, you must perform one of the sets of tasks in the following sections:. The notes in the sample configuration files refer to the ” Notes ” section at the end of this chapter. The examples describe four increasingly complex QLLC conversion topologies and possible router configurations for each.
The following sample configuration files describe the network shown in Figure This packet can be several thousand bytes long and the typical size for X. After the Token Ring FEP has been configured to send the largest possible I-frame, it is best to configure the router to support the same maximum I-frame size.
Task Command Define a ring group. To enable the router to open a connection to the local Token Ring device, perform the following task in interface configuration mode: The router is configured with source-route bridging SRB.

After the router ib, the appropriate frame conversion, it uses this route to forward frames to this serial device. Note the additional information in the section ” Other Customizing Considerations ” later in this chapter. Since this is a real bridge, we have to define the way it! SDLC sessions are always locally acknowledged.
