1.1 ! root 1: Help for Cisco 7200 simulator (dynamips-0.2.3) ! 2: ============================================== ! 3: Authors: Fabien Devaux, Christophe Fillot, MtvE ! 4: ! 5: Emulated hardware ! 6: ***************** ! 7: ! 8: By default, a NPE-200 is emulated. 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: The Serial driver (PA-4T+) is not working at all (the interfaces are only ! 17: "seen" by IOS). ! 18: ! 19: ! 20: Command Line Options overview ! 21: ***************************** ! 22: ! 23: -r <ram_size> : Set the virtual RAM size (default is 256 Mb) ! 24: -o <rom_size> : Set the virtual ROM size (default is 4 Mb) ! 25: -n <nvram_size> : Set the NVRAM size (default is 128 Kb) ! 26: -l <log_file> : Set logging file (default is pred_log0.txt) ! 27: -C <cfg_file> : Import an IOS configuration file into NVRAM ! 28: -R <rom_file> : Load an alternate ROM (default is embedded) ! 29: -s <sym_file> : Load symbol file ! 30: -c <conf_reg> : Set the configuration register (default is 0x2102) ! 31: -m <mac_addr> : Set the MAC address of the chassis (IOS chooses default) ! 32: -k <clock_div> : Set the clock divisor (default is 2) ! 33: -T <port> : Console is on TCP <port> (default is on the terminal) ! 34: -A <port> : AUX is on TCP <port> (default is no AUX port) ! 35: -i : Instruction block trace, very slow ! 36: -j : Disable the JIT compiler, very slow ! 37: -t <npe_type> : Select NPE type ! 38: -M <midplane> : Select Midplane ("std" or "vxr") ! 39: -p <pa_desc> : Define a Port Adapter ! 40: -a <cfg_file> : Virtual ATM switch configuration file ! 41: -b <cfg_file> : Virtual bridge configuration file ! 42: ! 43: ! 44: Command Line Options details ! 45: **************************** ! 46: ! 47: <clock_div> : ! 48: ! 49: Specify the clock divider (integer) based on the host clock. ! 50: Alter the value to match the CISCO clock with the real time. ! 51: The command "show clock" at the IOS' CLI will help you set this value. ! 52: ! 53: <pa_desc> : ! 54: ! 55: Format: slot:pa_driver:netio_type[:netio_parameters] ! 56: ! 57: slot : the number of the physical slot (starts from 0) ! 58: ! 59: pa_driver : the name of a port adapter driver in: ! 60: - C7200-IO-FE (FastEthernet, slot 0 only) ! 61: - PA-FE-TX (FastEthernet, slots 1 to 6) ! 62: - PA-4T+ (Serial, NOT WORKING) ! 63: - PA-A1 (ATM) ! 64: ! 65: netio_type : host interface for communication ! 66: ! 67: unix:<local_sock>:<remote_sock> ! 68: Use unix sockets for local communication. ! 69: <local_sock> is created and represents the local NIC. ! 70: <remote_sock> is the file used by the other interface. ! 71: (ex. "/tmp/local:/tmp/remote") ! 72: ! 73: tap:<tap_name> ! 74: Use a virtual ethernet device for communication. ! 75: <tap_name> is the name of the tap device (ex. "tap0") ! 76: ! 77: linux_eth:<dev_name> ! 78: Use a real ethernet device for communication (Linux specific). ! 79: <dev_name> is the name of the Ethernet device (ex. "eth0") ! 80: ! 81: udp:<local_port>:<remote_host>:<remote_port> ! 82: Use an UDP socket for connection between remote instances. ! 83: <local_port> is the port we listen to. ! 84: <remote_host> is the host listening the port you want to connect to. ! 85: <remote_port> is the port you want to connect to. ! 86: (ex.

The use of this virtual switch is not mandatory, you ! 155: can directly connect emulator instances for point-to-point ATM connections. ! 156: Please note that only basic VP/VC switching is supported, there is no ! 157: support for ILMI/QSAAL/... or other specific ATM protocols. ! 158: ! 159: Any emulator instance can act as a virtual ATM switch. ! 160: ! 161: Example of configuration file (specified by the "-a" option): ! 162: ! 163: # Virtual Interface List ! 164: IF:A0:udp:10001:127.0.0.1:10000 ! 165: IF:A1:udp:10002:127.0.0.1:10003 ! 166: IF:A2:udp:10004:127.0.0.1:10005 ! 167: ! 168: # VP connection between I0 and I1 ! 169: VP:A0:10:A1:20 ! 170: VP:A1:20:A0:10 ! 171: ! 172: # VP connection between I0 and I2 ! 173: VP:A0:11:A2:30 ! 174: VP:A2:30:A0:11 ! 175: ! 176: # VC connection between I1 and I2 ! 177: VC:A1:5:2:A2:7:3 ! 178: VC:A2:7:3:A1:5:2 ! 179: ! 180: In this example, we have 3 virtual interfaces, A0, A1 and A2.
