This chapter describes the function and displays the syntax for Native Client Interface Architecture (NCIA) server commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Bridging and IBM Networking Command Reference.
Use the clear ncia circuit privileged EXEC command to drop a specified NCIA circuit.
clear ncia circuit [id-number]| id-number | (Optional) Number assigned to identify the circuit. If no circuit ID number is specified, the command drops all circuits. |
Use the clear ncia client privileged EXEC command to terminate a specified active client connection.
clear ncia client [ip-address]| ip-address | (Optional) IP address of the client. If no IP address is specified in the command, the command terminates all active client connections. |
Use the clear ncia client registered privileged EXEC command to release the control block of a specified registered client after terminating the active connection to it.
clear ncia client registered [ip-address]| ip-address | (Optional) IP address of the registered client. If no IP address is specified in the command, the command releases the control blocks of all registered clients after terminating any active connections to them. |
Use the ncia privileged EXEC command to stop and start an NCIA server.
ncia {start | stop}| start | Starts the NCIA server when it has been stopped using the ncia stop command. |
| stop | Stops the NCIA server. When the server is stopped, all clients are disconnected, all circuits are dropped, and no clients can connect to the server. |
Use the ncia client global configuration command to configure an NCIA client on a Cisco router. Use the no form of this command to remove the configuration.
ncia client server-number client-ip-address virtual-mac-address [sna | all]| server-number | Number assigned to identify the server. Currently, the server number must be configured with a value of 1. |
| client-ip-address | IP address of the client. |
| virtual-mac-address | Virtual MAC address of the client. |
| sna | (Optional) NCIA client only supports SNA traffic. |
| all | (Optional) NCIA client supports all types of traffic. If you do not specify all as the supported traffic type when you configure an NCIA client, the client only supports SNA traffic. |
Use the ncia rsrb global configuration command to configure an RSRB ring to associate with an NCIA server on a Cisco router. Use the no form of this command to remove the configuration.
ncia rsrb virtual-ring local-bridge local-ring ncia-bridge ncia-ring virtual-mac-address| virtual-ring | RSRB ring group number. This number corresponds to the ring-number parameter defined by a source-bridge ring-group command. |
| local-bridge | Number of the bridge connecting the virtual ring and the local ring. |
| local-ring | Number of the virtual ring connecting the virtual ring and the NCIA ring. |
| ncia-bridge | Number of the bridge connecting the local ring and the NCIA ring. |
| ncia-ring | NCIA ring group number. This number corresponds to the ring-number parameter defined by a source-bridge ring-group command. |
| virtual-mac-address | Local ring virtual MAC address. |
Use the ncia server global configuration command to configure an NCIA server on a Cisco router. Use the no form of this command to remove the configuration.
ncia server server-number server-ip-address server-virtual-mac-address virtual-mac-address virtual-mac-range [inbound-only] [keepalive seconds] [tcp_keepalive minutes]| server-number | Number assigned to identify the server. Currently, the server number must be configured with a value of 1. |
| server-ip-address | IP address used to accept the incoming connection, or to make an out-going connection. |
| server-virtual-mac-address | MAC address of the server. |
| virtual-mac-address | The first MAC address of the virtual MAC address pool. |
| virtual-mac-range | The range of virtual MAC addresses that can be assigned to the client. The valid range is 1 to 4095. This number sets the upper limit on the number of contiguous MAC addresses that make up the MAC address pool. |
| inbound-only | (Optional) When inbound-only is configured, the NCIA server cannot make an out-going connection. |
| keepalive seconds | (Optional) Keepalive interval in seconds. The valid range is 0 to 1200. Setting the value to 0 turns the keepalive off. |
| tcp_keepalive minutes | (Optional) TCP keepalive processing interval in minutes. The valid range is 0 to 99 minutes. Setting the value to 0 stops TCP from sending keepalive packets when an NCIA client is idle. If no tcp_keepalive value is set, the default waiting period for TCP keepalive packets is 20 minutes. |
Use the show ncia circuits privileged EXEC command to display the state of all circuits involving this MAC address as a source and destination.
show ncia circuits [id-number]| id-number | (Optional) Number assigned to identify the circuit. If no ID number is specified, the command lists information for all circuits. |
Use the show ncia client EXEC command to display the status of the NCIA client.
show ncia client [sap-list] [ip-address]| sap-list | (Optional) Display the SAPs supported by the client. If the sap-list option is not specified, the command does not display SAP list information. |
| ip-address | (Optional) Client IP address. If no IP address is specified, the command lists information for all clients. |
Use the show ncia server EXEC command to display the state of the NCIA server.
show ncia server [server-number]| server-number | (Optional) NCIA server number. If no server number is specified, the command lists information for all servers. |
