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).

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.

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)

123: Virtual Bridge
124: **************
125:
126: The virtual bridge is used to emulate a shared network between emulator
127: instances.
128:
129: Any emulator instance can ast as a virtual bridge.
130:
131: The configuration file (specified by the "-b" option) contains a list of
132: NetIO descriptors, which the following syntax: netio_type[:netio_parameters]
133:
134: Example:
135:
136: # Connection to instance "I0"
137: udp:10000:127.0.0.1:10001
138:
139: # Connection to instance "I1"
140: udp:10002:127.0.0.1:10003
141:
142: # Connection to instance "I2"
143: udp:10004:127.0.0.1:10005
144:
145: The "I0" would be launched with the following parameters:
146:
147: dynamips ios.bin -p 1:PA-FE-TX:udp:10001:127.0.0.1:10000

150: Virtual ATM switch
151: ******************
152:
153: The virtual ATM switch fabric is used to emulate an ATM backbone between
154: emulator instances. 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. The syntax
181: for interface definition is similar to Port Adapters:
182:
183: IF:interface_name:netio_type[:netio_parameters]
184:
185: You can do VP switching or VC switching:
186:
187: 1) VP switching
188:
189: syntax: VP:input_if:input_vpi:output_if:output_vpi
190:
191: 2) VC switching
192:
193: syntax: VC:input_if:input_vpi:input_vci:output_if:output_vpi:output_vci
194:

204: # a0/vpi=1/vci=100 connects to a1/vpi=2/vci=200
