Interfaces Implemented

Notifiers

cell-change

Notifier that is triggered after the object's cell was changed.

object-delete

Notifier that is triggered just before Simics object is deleted.

queue-change

Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.

Commands for this class

• info – print information about the object
• packet-rate – set or display the packets per second rate
• packet-size – set or display the packet size
• start – start generating traffic
• status – print status of the object
• stop – stop generating traffic

Attributes

start_count

Optional attribute; read/write access; type: i
The number of packets to send after starting traffic generator, intended to be used by start signal.Zero value means an unlimited number of packets.

led_enabled_target

Optional attribute; read/write access; type: n|o|[os]
Enabled status LED, signal target.

countdown_target

Optional attribute; read/write access; type: n|o|[os]
Packets left to send (countdown), signal target.

crc_errors_target

Optional attribute; read/write access; type: n|o|[os]
The number of CRC errors seen, signal target.

link

Optional attribute; read/write access; type: o|n
The network link that this service node Ethernet device is attached to.

link_state

Optional attribute; read/write access; type: o|n
The network link that this service node Ethernet device is attached to (for checkpointing).

mac_address

Optional attribute; read/write access; type: s
Ethernet (MAC) address of the network interface.

ip

Required attribute; read/write access; type: s
IP address assigned to the device.

netmask

Required attribute; read/write access; type: s|i
Netmask defining the subnet for the device.

dst_ip

Required attribute; read/write access; type: s
IP address to send packets to.

gateway

Optional attribute; read/write access; type: s|n
IP address of gateway.

port

Optional attribute; read/write access; type: i
The port to send packets to and receive packets on.

pps

Optional attribute; read/write access; type: i
Number of packets per second to send.

packet_size

Optional attribute; read/write access; type: i
The size of data packets to send.

count

Optional attribute; read/write access; type: i|n
The number of packets left to send until traffic generation stops. A nil value means an unlimited number of packets.

state

Optional attribute; read/write access; type: i
Current state of traffic generator.

enabled

Optional attribute; read/write access; type: i
Set to 1 to enable traffic generation.

probe

Optional attribute; read/write access; type: b
Probe the connection with ICMP ECHO before generating traffic. This might help fill ARP caches in routers on the way to reduce the risk of dropping the first real packet.

model_crc

Optional attribute; read/write access; type: b
If set to true, the device will calculate and include an Ethernet CRC on all transmitted frames, and check the CRC on received frames.

ip_id

Optional attribute; read/write access; type: i
Internal state.

receive_stats

Optional attribute; read/write access; type: i
Internal state.

rx_packets

Optional attribute; read/write access; type: i
Internal state.

rx_bytes

Optional attribute; read/write access; type: i
Internal state.

neighbors

Optional attribute; read/write access; type: D
Internal state.

total_rx_packets

Optional attribute; read/write access; type: i
Total number of UDP packets received on the test port.

total_tx_packets

Optional attribute; read/write access; type: i
Total number of UDP packets transmitted on the test port.

crc_errors

Optional attribute; read/write access; type: i
The number of CRC errors seen.
