This chapter explains the function and syntax of the NCIA client/server commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Cisco IOS Bridging and IBM Networking Command Reference, Volume 1, Release 12.1.
To drop a specified NCIA circuit, use the clear ncia circuit privileged EXEC command.
clear ncia circuit [id-number]
Syntax Description
id-number (Optional) Number assigned to identify the circuit. If no circuit ID number is specified, the command drops all circuits.
To terminate a specified active client connection, use the clear ncia client privileged EXEC command.
clear ncia client [ip-address]
Syntax Description
ip-address (Optional) IP address of the client. If no IP address is specified in the command, the command terminates all active client connections.
To release the control block of a specified registered client after terminating the active connection to it, use the clear ncia client registered privileged EXEC command.
clear ncia client registered [ip-address]
Syntax Description
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.
To stop and start an NCIA server, use the ncia privileged EXEC command.
ncia {start | stop}
Syntax Description
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.
To configure an NCIA client on a Cisco router, use the ncia client global configuration command. Use the no form of this command to remove the configuration.
ncia client server-number client-ip-address virtual-mac-address [sna | all]
Syntax Description
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.
To configure an RSRB ring to associate with an NCIA server on a Cisco router, use the ncia rsrb global configuration command. 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
Syntax Description
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.
To configure an NCIA server on a Cisco router, use the ncia server global configuration command. 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]
Syntax Description
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 outgoing 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 outgoing 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.
To display the state of all circuits involving this MAC address as a source and destination, use the show ncia circuits privileged EXEC command.
show ncia circuits [id-number]
Syntax Description
id-number (Optional) Number assigned to identify the circuit. If no ID number is specified, the command lists information for all circuits.
To display the status of the NCIA client, use the show ncia client EXEC command.
show ncia client [sap-list] [ip-address]
Syntax Description
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.
To display the state of the NCIA server, use the show ncia server EXEC command.
show ncia server [server-number]
Syntax Description
server-number (Optional) NCIA server number. If no server number is specified, the command lists information for all servers.
