To define a link to an SNA host over Token Ring, Ethernet, FDDI, RSRB, or virtual data-link control connections, use the sna host global configuration command. Use the no form of this command to cancel the definition.
sna host host-name xid-snd xid rmac remote-mac [rsap remote-sap] [lsap local-sap] [interface slot/port] [window window-size] [maxiframe max-iframe] [retries retry-count] [retry-timeout retry-timeout] [focalpoint]
Syntax Description
host-name SNA host. xid-snd xid XID that will be sent to the host during connection establishment. The XID value is 8 hexadecimal digits that include both block and ID numbers. For example, if the XID value is 05D00001, the block number is 05D and the ID number is 00001. rmac remote-mac MAC address of the remote host PU. rsap remote-sap (Optional) SAP address of the remote host PU. The default is 4. lsap local-sap (Optional) Local SAP address used by the SNA Service Point to establish connection with the remote host. The default is 12. interface slot/port (Optional) Slot and port number of the interface. window window-size (Optional) Send and receive window sizes used for the host link. The range is 1 to 127. The default is 7. maxiframe max-iframe (Optional) Send and receive maximum I-frame sizes used for the host link. The range is 64 to 18432. The default is 1472. retries retry-count (Optional) Number of times the SNA Service Point attempts to retry establishing connection with remote host PU. The range is 0 to 255 (0 = no retry attempts, 255 = infinite retry attempts). The default is 255. retry-timeout retry-timeout (Optional) Delay (in seconds) between attempts to retry establishing connection with remote host PU. The range is 1 to 600 seconds. The default is 30 seconds. focalpoint (Optional) Host link to be used for the focal point support.
Syntax Description
local-virtual-ring Local virtual ring number. bridge-number Virtual bridge number. The valid range is 1 to 15. target-virtual-ring Target virtual ring number. virtual-macaddr Virtual MAC address.
To enable an RSRB SAP for use by SNA Service Point, use the sna rsrb enable-host global configuration command. Use the no form of this command to disable the RSRB SAP.
sna rsrb enable-host [lsap local-sap]
Syntax Description
lsap local-sap (Optional) Specifies that the local SAP address will be activated as an upstream SAP for both receiving incoming connections attempts and for starting outgoing connection attempts. The default is 12.
To specify that an attempt will be made to connect to the remote resource defined by host name through the RSRB, use the sna rsrb start global configuration command. Use the no form of this command to cancel the definition.
sna rsrb start host-name
Syntax Description
host-name The name of a host defined in an sna host or equivalent command.
To initiate a connection to a remote resource, use the sna start interface configuration command. Use the no form of this command to cancel the connection attempt.
sna start [resource-name]
Syntax Description
resource-name (Optional) Name of a host defined in an sna host command.
To identify the local virtual ring and virtual MAC address that will be used to establish SNA host connections over DLSw+ using virtual data-link control, use the sna vdlc global configuration command. Use the no form of this command to cancel the definition.
sna vdlc ring-group virtual-mac-address
Syntax Description
ring-group Local virtual ring number identifying the SRB ring group. virtual-mac-address Virtual MAC address that represents the SNA virtual data-link control.
Syntax Description
lsap local-sap (Optional) Specifies that the local SAP address will be activated as an upstream SAP for both receiving incoming connection attempts and for starting outgoing connection attempts. The default is 12.
To specify that an attempt will be made to connect to the remote resource defined by host name through virtual data-link control, use the sna vdlc start global configuration command. Use the no form of this command to cancel the definition.
sna vdlc start host-name
Syntax Description
host-name The name of a host defined in an sna host or equivalent command.
