| retries retry-count | (Optional) Specifies the 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) Specifies the 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) Specifies that the host link will be used for the focal point support. |
Use the sna rsrb interface configuration command to specify the entities that the SNA feature will simulate at the remote source-route bridge. Use the no form of this command to cancel the specification.
sna rsrb local-virtual-ring bridge-number target-virtual-ring virtual-macaddr| 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. |
Use the sna rsrb enable-host global configuration command to enable an RSRB SAP for use by SNA Service Point. Use the no form of this command to disable the RSRB SAP.
sna rsrb enable-host [lsap local-sap]| 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. |
Use the sna rsrb start global configuration command to specify that an attempt will be made to connect to the remote resource defined by host name through the RSRB. Use the no form of this command to cancel the definition.
sna rsrb start host-name| host-name | The name of a host defined in an sna host (Token Ring, Ethernet, FDDI, RSRB, VDLC) or equivalent command. |
Use the sna start interface configuration command to initiate a connection to a remote resource. Use the no form of this command to cancel the connection attempt.
sna start [resource-name]| resource-name | (Optional) Name of a host defined in an sna host command. |
Use the sna vdlc global configuration 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 no form of this command to cancel the definition.
sna vdlc ring-group virtual-mac-address| ring-group | Local virtual ring number identifying SRB ring-group. |
| virtual-mac-address | Virtual MAC address that represents SNA virtual data link control. |
Use the sna vdlc enable-host global configuration command to enable a SAP for use by SNA Service Point. Use the no form of this command to disable the SAP.
sna vdlc enable-host [lsap local-sap]| 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. |
Use the sna vdlc start global configuration command 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 no form of this command to cancel the definition.
sna vdlc start host-name| host-name | The name of a host defined in an sna host (Token Ring, Ethernet, FDDI, RSRB, VDLC) or equivalent command. |
