You can choose the NPE type with the 9: "-t" option. It is possible to select "npe-100", "npe-150", "npe-175", 10: "npe-200", "npe-225", "npe-300" and "npe-400". The "npe-g1" is not working. 11: 12: Please note that you must use the C7200-IO-FE PA driver as IO card if you 13: want a FastEthernet interface in slot 0. For other slots, you must use 14: the PA-FE-TX driver. 15: 16: 17: Command Line Options overview 18: ***************************** 19: 20: -r <ram_size> : Set the virtual RAM size (default is 256 Mb) 21: -o <rom_size> : Set the virtual ROM size (default is 4 Mb) 22: -n <nvram_size> : Set the NVRAM size (default is 128 Kb) 23: -l <log_file> : Set logging file (default is pred_log0.txt) 24: -C <cfg_file> : Import an IOS configuration file into NVRAM 1.1.1.3 ! root 25: -X : Do not use a file to simulate RAM (faster) 1.1 root 26: -R <rom_file> : Load an alternate ROM (default is embedded) 1.1.1.3 ! root 27: -S <sym_file> : Load a symbol file 1.1 root 28: -c <conf_reg> : Set the configuration register (default is 0x2102) 29: -m <mac_addr> : Set the MAC address of the chassis (IOS chooses default) 30: -k <clock_div> : Set the clock divisor (default is 2) 31: -T <port> : Console is on TCP <port> (default is on the terminal) 32: -A <port> : AUX is on TCP <port> (default is no AUX port) 33: -i : Instruction block trace, very slow 34: -j : Disable the JIT compiler, very slow 35: -t <npe_type> : Select NPE type 36: -M <midplane> : Select Midplane ("std" or "vxr") 37: -p <pa_desc> : Define a Port Adapter 1.1.1.3 ! root 38: -s <pa_nio> : Bind a Network IO interface to a Port Adapter 1.1 root 39: -a <cfg_file> : Virtual ATM switch configuration file 1.1.1.3 ! root 40: -f <cfg_file> : Virtual Frame relay switch configuration file 1.1 root 41: -b <cfg_file> : Virtual bridge configuration file 1.1.1.3 ! root 42: -e : Show network device list of the host machine 1.1 root 43: 44: 45: Command Line Options details 46: **************************** 47: 48: <clock_div> : 49: 50: Specify the clock divider (integer) based on the host clock. 51: Alter the value to match the CISCO clock with the real time. 52: The command "show clock" at the IOS' CLI will help you set this value. 53: 54: <pa_desc> : 55: 56: Format: slot:pa_driver:netio_type[:netio_parameters] 57: 58: slot : the number of the physical slot (starts from 0) 59: 60: pa_driver : the name of a port adapter driver in: 61: - C7200-IO-FE (FastEthernet, slot 0 only) 62: - PA-FE-TX (FastEthernet, slots 1 to 6) 1.1.1.3 ! root 63: - PA-4T+ (Serial, 4 ports) ! 64: - PA-8T (Serial, 8 ports) 1.1 root 65: - PA-A1 (ATM) 66: 1.1.1.3 ! root 67: <pa_nio> : ! 68: ! 69: Format: slot:port:netio_type[:netio_parameters] ! 70: ! 71: slot : the number of the physical slot (starts from 0) ! 72: port : the port in the specified slot (starts from 0) ! 73: 1.1 root 74: netio_type : host interface for communication 75: 76: unix:<local_sock>:<remote_sock> 77: Use unix sockets for local communication. 78: <local_sock> is created and represents the local NIC. 79: <remote_sock> is the file used by the other interface. 80: (ex.
