To generate traffic using Y.1564, complete the following tasks:
• Configure EVC on the interface path such that the Layer 2/L2VPN path should be complete between
transmitter and receiver.
• Configure Traffic Generator on the transmitter.
• Configure ethernet loopback on the receiver. For information on Ethernet loopback, see
Understanding Ethernet Loopback, page 10-51.
• Start the IP SLA session.
Note Using traffic generator, a maximum traffic of 1GB is generated.
Restrictions
• A single traffic session is generated.
• Traffic generation will not be supported on VLAN interface.
• One-way traffic generation and passive measurement features are not supported.
• Payload signature verification is not supported.
• The QoS functions like classification and policing are supported on the ingress EVC.
• Internal mode traffic generation cannot be configured on port channel interfaces.
• Maximum throughput rate is 1GB.
