Chapter 37: Configuring RFC 2544-Based Benchmarking Tests
and the other end or the destination device to reflect the received frames back to the
initiator.
RFC 2544 generator and reflector are supported with testing bandwidth up to 1 Gbps.
ACX5048 and ACX5096 routers supports test bandwidth of up to 40 Gbps.
The test session is supported in out-of-service mode for the underlying service. You
must not transmit any traffic to the UNI port, configured as a generator or a reflector,
that is being tested during the duration of the test. However, other services that are
not configured for the testing session are not impacted.
Devices embedded with benchmarking test capabilities (generators and reflectors)
interoperate with other Juniper Networks devices that support the RFC 2544-based
generator or reflector functionality.
RFC 2544 generator traffic undergoes the same traffic classifier and policer or shaper
processing as the ingress customer traffic from the UNI port.
RFC 2544 generator produces a report with clear details of pass or fail for each critical
testing metric, based on the configured thresholds.
The testing packets can be configured and the format of the packet depends on the
underlying service on which the test is configured. For IP-based service, the IP or port
values can be configured. For Ethernet-based service, unicast untagged or VLAN
ID-tagged dot1p formats (IEEE 802.1p or packet classification Layer 2 headers) are
supported. The Ethernet destination address and source address that you configured
are used.
You can run RFC 2544 benchmarking inet tests on Layer 3 VPN or virtual router.
For an service, each test session needs to use a unique UDP port. On the initiator
inet
device, the source UDP port that you specify by using the source-udp-port statement
must be unique and not used by other UDP services that terminate at the initiator. On
the reflector device, the UDP port of the destination to be used in the UDP header for
the generated frames by using the statement must be unique
destination-udp-port
and not used by other UDP services that terminate at the reflector.
You must start the test on the router that operates as the reflector before you start
the test on router that functions as the initiator.
You must configure the size of the test packet based on the configured MTU of the
packets.
For computation of the test results for a user-to-network interface (UNI) or ingress
direction of an Ethernet pseudowire service, the customer edge (CE) device that is
configured as a reflector for must have the reflected destination address resolved
inet
using ARP or a statically configured route must be present on the CE device to connect
to the initiator.
For benchmarking tests on the UNI direction of an Ethernet pseudowire service, if
reflection mode is configured, you must configure a static ARP entry. Otherwise, the
tests fail when test frames on the UNI interface are reflected. ARP resolution does not
enable a successful reflection of test frames for UNI interfaces.
