This chapter describes the function and displays the syntax of each SDLLC and QLLC command. For more information about defaults and usage guidelines, see the corresponding chapter of the Router Products Command Reference publication.

[no] qllc largest-packet virtual-mac-addr max-size

Use the qllc largest-packet interface configuration command to indicate the maximum size of the SNA packet that can be sent or received on an X.25 interface configured for QLLC conversion. Use the no form of this command to restore the default largest packet size.

virtual-mac-addr	Virtual MAC address associated with the remote X.25 device, as defined using the x25 map or x25 pvc commands. This address is written as a dotted triple of four-digit hexadecimal numbers.
max-size	Maximum size, in bytes, of the SNA packet that can be sent or received on the X.25 interface configured for QLLC conversion. This value agrees with the value configured in the remote SNA device. The valid range is 0 through 1024.

[no] qllc partner virtual-mac-addr mac-addr

Use the qllc partner interface configuration command to enable a router configured for QLLC conversion to open a connection to the local Token Ring device on behalf of the remote X.25 device when an incoming call is received. Use the no form of this command to disable this capability.

virtual-mac-addr	Virtual MAC address associated with the remote X.25 device, as defined using the x25 map or x25 pvc command. This address is written as a dotted triple of four-digit hexadecimal numbers.
mac-addr	48-bit MAC address of the Token Ring host that will communicate with the remote X.25 device.

[no] qllc sap virtual-mac-addr ssap dsap

Use the qllc sap interface configuration command to associate a SAP value other than the default SAP value with a serial interface configured for X.25 communication and QLLC conversion. The no form of this command returns this SAP value to its default state.

virtual-mac-addr	Virtual MAC address associated with the remote X.25 device, as defined using the x25 map or x25 pvc command.
ssap	Source SAP value. It can be a decimal number in the range 2 through 254.
dsap	Destination SAP value. It can be a decimal number in the range 2 through 254.

[no] qllc srb virtual-mac-addr srn trn

Use the qllc srb interface configuration command to enable the use of QLLC conversion on a serial interface configured for X.25 communication. The no form of this command disables QLLC conversion on the interface.

virtual-mac-addr	Virtual MAC address associated with the remote X.25 device, as defined using the x25 map or x25 pvc command. It can be 1 to 15 digits long.
srn	Source ring number. This value defines a virtual ring for all of the remote X.25 devices attached to the QLLC interface. Any number of QLLC conversion connections using the same X.25 serial interface can share a common source ring. However, this source ring must be a unique hexadecimal ring number within the source-bridged network.
trn	Target ring number. It must be a virtual ring group that has been defined with the source-bridge ring-group command. If the router has only one Token Ring interface and is bridging from the remote X.25 devices to this interface, then trn is the number of the ring on that Token Ring interface. If the router has several Token Ring interfaces and interconnects them by means of the source-bridge ring-group command, then trn is the number of that virtual ring group, as assigned using the source-bridge ring-group global configuration command.

[no] sdllc partner mac-address sdlc-address

Use the sdllc partner interface configuration command to enable device-initiated connections for SDLLC. This command must be specified for the serial interface that links to the serial line device. Use the no form of this command to cancel the original instruction.
