IP SLA—Service Performance Testing

This module describes how to configure the ITU-T Y.1564 Ethernet service performance test methodology that measures the ability of a network device to enable movement of traffic at the configured data rate.

Information About Service Performance Operations

Y.1564 is an Ethernet service activation test methodology and is the standard for turning up, installing, and troubleshooting Ethernet and IP based services. Y.1564 is the only standard test methodology that allows a complete validation of Ethernet service-level agreements (SLAs) in a single test.

Service activation testing (SAT) is designed to measure the ability of a Device Under Test (DUT) or a network under test to properly forward traffic in different states.

Effective with Cisco IOS XE Everest Release 16.5.1, 10 Gigabit (10G) SAT session is supported on Cisco RSP2 and Cisco RSP3 Modules. Any SAT session with a rate-step greater than or equal to 1 Gbps is considered as 10G SAT session.

Cisco implementation of ITU-T Y.1564 has three key objectives:

  • To serve as a network SLA validation tool, ensuring that a service meets its guaranteed performance settings in a controlled test time.

  • To ensure that all services carried by the network meet their SLA objectives at their maximum committed rate, thus proving that under maximum load, network devices and paths can support all traffic as designed.

  • To perform medium-term and long-term service testing, confirming that network elements can properly carry all services while under stress during a soaking period.

The following Key Performance Indicators (KPI) metrics are collected to ensure that the configured SLAs are met for the service or stream. These are service acceptance criteria metrics.

  • Information Rate (IR) or throughput—Measures the maximum rate at which none of the offered frames are dropped by the device under test (DUT). This measurement translates into the available bandwidth of the Ethernet virtual connection (EVC).

  • Frame Transfer Delay (FTD) or latency—Measures the round-trip time (RTT) taken by a test frame to travel through a network device, or across the network and back to the test port.

  • Frame Loss Ratio (FLR)—Measures the number of packets lost from the total number of packets sent. Frame loss can be due to a number of issues such as network congestion or errors during transmissions.

  • Frame Delay Variation (FDV) or jitter—Measures the variations in the time delays between packet deliveries.

The below table presents the KPI support matrix for RSP3 Module:

We always recommend that you use FPGA-based SADT.

Because they interconnect segments, forwarding devices (switches and routers) and network interface units are the basis of any network. If a service is not correctly configured on any one of these devices within the end-to-end path, network performance can be greatly affected, leading to potential service outages and network-wide issues such as congestion and link failures. Service performance testing is designed to measure the ability of DUT or network under test, to correctly forward traffic in different states. The Cisco implementation of ITU-T Y.1564 includes the following service performance tests:

  • Minimum data rate to CIR—Bandwidth is generated from the minimum data rate to the committed information rate (CIR) for the test stream. KPI for Y.1564 are then measured to ensure that the configured service acceptance criteria (SAC) are met.

  • CIR to EIR—Bandwidth is ramped up from the CIR to the excess information rate (EIR) for the test stream. Because EIR is not guaranteed, only the transfer rate is measured to ensure that CIR is the minimum bandwidth up to the maximum EIR. Other KPI is not measured.

Service performance supports four operational modes: two-way statistics collection, one-way statistics collection, passive measurement mode, and traffic generator mode. Statistics are calculated, collected, and reported to the IP SLAs module. The statistics database stores historical statistics pertaining to the operations that have been executed.

  • One-way statistics collection—Both the passive measurement mode and the traffic generator mode are used in conjunction with each other. One device sends traffic as the generator and another device receives traffic in the passive mode and records the statistics. The passive mode is distinct from the two-way mode, where the remote device records statistics instead of looping back the traffic and the sending device records only the transmit statistics.

  • Two-way statistics collection—All the measurements are collected by the sender. The remote target must be in the loopback mode for the two-way statistics to work. Loopback mode enables the traffic from the sender to reach the target and be returned to the sender.

  • Passive measurement mode—This mode is enabled by excluding a configured traffic profile. A passive measurement operation does not generate live traffic. The operation collects only statistics for the target configured for the operation.

  • Traffic generator mode—This mode records transmit statistics for the number of packets and bytes sent.

Information About Configuring Y.1564 to Generate and Measure Ethernet Traffic

Y.1564 is an ethernet service activation or performance test methodology for turning up, installing, and troubleshooting ethernet and IP based services. This test methodology allows for complete validation of ethernet service-level agreements (SLAs) in a single test. Using the traffic generator performance profile, you can create the traffic based on your requirements. Network performance indicators like throughput, loss, and availability are analyzed using layer 2 traffic with various bandwidth profiles. Availability is inversely proportional to frame loss ratio.

The figure below shows the Traffic Generator topology describing the traffic flow in the external and internal modes. The traffic is generated at the wire-side of Network-to-Network Interface (NNI) and is transmitted to the responder through the same interface for the external mode. The traffic is generated at the User-to-Network Interface (UNI) and transmitted to the responder through NNI respectively for the internal mode. The external mode is used to measure the throughput and loss at the NNI port whereas internal mode is used to measure the throughput and loss at the UNI port. During traffic generation, traffic at other ports is not affected by the generated traffic and can continue to switch network traffic.

Effective from the Cisco IOS XE 16.12.x release, 10G SAT External is supported on the Cisco Router.

Prerequisites for IP SLA - Service Performance Testing

Ensure that the direction configured for the measurement-type direction {internal | external} and the profile traffic direction {internal | external} commands is the same.

Restrictions for IP SLA - Service Performance Operation

  • The IP SLA sender egress and ingress VLAN should match. Ensure to configure VLAN translation in the same context.

  • IP SLA classification is supported only for the DSCP/TOS marking from IP SLA command.

  • One-way statistics collection is not supported.

  • Layer 2 Color-Aware IP SLA is not supported for external traffic direction.

  • The bridge-domain target type is not supported for external traffic direction.

  • Color-Aware SLA for bridge-domain target type is not supported.

  • Since SAT traffic is intrusive, any other traffic is dropped for a particular EFP.

  • IPv6 address is not supported as a destination address.

  • For two-way mode, the Multicast destination support is not available for IP SLA (layer 3 SLA).

  • IP SLA does not support enabling a signature.

  • SLA on the target with Custom Ethertype encapsulation is not supported.

  • SLA on the target with 802.1ad enabled is not supported.

  • Multiple active sessions are not supported on the same Ethernet EFP.

  • For operations with two-way measurements, any one of the parameters, namely, port, destination MAC address, and encapsulation VLANs, should be different for SLA sessions that are simultaneously active.

  • Scaling is dependent on the availability of the terminal SAT session, terminal loopback session, and egress Span session.

  • For layer 2 virtual forwarding instance (VFI) or Switched Virtual Interface (SVI), only target type EFP and generator or measurement type terminal sessions should be used.

  • For IMIX traffic, packet sizes of 64 bytes, 512 bytes, and 1518 bytes are supported. These packet sizes are forwarded in the ratio 7:4:1.

  • For operations with layer 2 and layer 3 SLA on Trunk EFP, outer VLAN tag of the packet is mandatory.

  • While a SLA session is in progress, dynamic addition of MAC access lists (ACLs) does not affect the SLA traffic.

  • Priority tag SLA in external direction is supported only when the inner tag and outer tag are marked as priority tags.

  • Facility loopback session cannot be started on a port configured as a SPAN source.

  • Terminal SLA session cannot be started on a port configured as a SPAN destination.

  • Facility SLA session cannot be started on a port configured as a SPAN source.

  • Source MAC address should not be configured as multicast or broadcast MAC address.

  • PIM Sparse mode is not supported for traffic generator mode and passive mode.

  • SAT session fails with proper syslog messages for the following reasons:

  • Only interface or service instance is supported for external session.

  • VLAN or Bridge-domain service types are not supported for facility Traffic Generator and Traffic Measurement.

  • EFP or Trunk EFP or bridge-domain is shut.

  • The following table shows the supported egress and ingress QOS on the sender side core interface for Ethernet and IP target SLA.

    Not supported

  • Service Activation layer 3 Loopback is not supported with the target interface belonging to ASIC 1 in RSP2.

  • Generation of burst traffic is not supported; therefore, configuration of CBS and EBS is not supported.

  • IP SLAs configured with start-time now keyword need to be restarted after reload.

  • PPS mode is not supported with IMIX packet size.

  • IP SLA V2 (RFC 6812) and V3 are not supported on RSP3.

  • For the color aware SADT to work as expected, rewrite EFP should be present.

Restrictions on the Cisco RSP2 Module

  • Only DSCP-based marking is supported for IP Target operations.

  • The session duration is limited to multiples of 10; user input is rounded down to the nearest multiple of 10.

  • Quality of Service (QOS) on any target type with IP SLA is not supported on layer 2 and layer 3 routers.

  • Layer 3 IP SLA is not supported on external traffic direction.

  • Layer 3 SLA Loopback is not supported for labelled incoming packets.

  • For layer 3 Loopback, if the target type is service instance, the core and access side EFP should have the same encapsulation.

  • For layer 3 Loopback, if the target type is VRF, only encapsulation untagged is supported. The loopback session is not supported for the VRF target types even for same encapsulation on access and core EFPs.

  • For layer 3 Loopback, if the target type is bridge domain, only encapsulation untagged is supported. The loopback session is not supported for the bridge domain target types, even for the same encapsulation on access and core EFPs.

  • For operations with passive measurement mode and target type EFP, the same destination MAC address cannot be used for any other traffic on a port as the loopback MAC Address Tables (CAM) tables contain the channel numbers and the destination MAC address. As a result, multiple SLAs with the same destination MAC address, on the same port active at the same time, are not supported for passive measurement mode.

  • For operations with EFP using XConnect, only the target type EFP and terminal sessions for Tx and Rx statistics are supported.

  • For layer 2 internal sessions with Rx statistics, either only four non-color-aware sessions, or one color-aware session and one non-color-aware session are supported.

  • Port channel is not supported.

  • When the source MAC address is not configured on layer 2 SLA, any one system reserved MAC of 16 MAC addresses is used.

  • For operations with SLA in PPS mode, an additional packet is forwarded.

  • The minimum supported value for rate step is 1024 pps.

  • While running SADT, the packet that matches the SLA profile source MAC, VLAN or untagged, is counted in the RX. For example, if you schedule an SLA and start PING in the same time frame, PING fails, since the ping acknowledgement packet is accounted in SLA RX packet. Similarly, the LL discovery packet from the responder is accounted in SLA RX. So, there is one extra packet and the same packet is not accounted in the LL discovery counter.

Restrictions for 10G SAT

  • The IP SLA packets are generated and forwarded in ratio of 1:1:1:1:1 from UNI or NNI port based on your configuration.

  • 10G service activation test (SAT) is supported only for Layer 2 traffic in external and internal direction.

  • 10G SAT is not supported in internal direction for releases prior to 16.12.x.

  • Only color blind configurations are supported. CIR, EIR, and other color aware parameters is not supported.

  • 10G SAT can only run in two-way mode.

  • With 10G SAT, only throughput and frame loss can be measured. Delay and jitter measurements are not supported.

  • Effective from Cisco IOS XE Gibraltar 16.12.1, Delay, and Jitter measurements are supported.

  • 10G SAT target type that is supported is only on access EFP.

  • A combination of 1G and 10G SAT sessions cannot be run in parallel. Also, two 10G SAT sessions cannot be run in parallel.

  • At SLA run time, SAT statistics may not match. Statistics must be validated only after SLA completes. While SAT SLA is running, there might be instances where Rx might be greater than Tx. This is because of slow retrieval of statistics from the hardware. Statistics should be verified only after SAT operation is complete.

  • Duration time is rounded off in multiples of 10.

  • Layer 3 packets for Layer 2 facility SAT 10G session is not supported.

    • Only Layer 2 related parameters (SRC, MAC, VLAN, COS) should be configured while constructing the packet profile.

    • Ethertype of IPv4 or IPv6 is not supported.

    • Layer 3 packet headers should not be used in profile packet.

  • Overall throughput in the system is slightly lesser than the rate-step mentioned value.

  • Multiple rate-steps that are mentioned in a single command can only be mentioned in incremental order.

  • With 10G SAT running in external mode, while QoS egress shaper policy is applied on the same SAT interface, SAT traffic generation is being affected based on the shaper value. SAT rate-step is adjusted by shaper policy. However, when policer based policy is applied inbound, there is no impact with regards to SAT traffic being policed. Despite the policer value configured, no policing happens for the return traffic on SAT interface. This is due to the configured internal ACL to handle the SAT statistics.

  • Broadcast and multicast destination MAC is not supported.

  • If a 10G SAT session is running (with a rate-step greater than or equal to 1 Gbps), a second 1G or 10G SAT session should not be run. That is, parallel execution is not supported with 10G SAT.

  • The SAT rate-step upper limits should be defined in such a way that BFD has some bandwidth for itself and ensures that the OSPF flaps do not occur. The upper limit for FPGA traffic generation for SAT is same in both SAT 1G and 10G. So, the upper limit of SAT 1G x 10 are applicable for SAT 10G to avoid the OSPF flaps.

  • OIR and SSO are not supported with SAT. SLA is to be stopped and re-started manually after these triggers.

  • SADT session and Ethernet loopback (ELB) on the same service instance of an interface is not supported.

  • 10G SAT with 802.1ad is not supported.

  • A delay of 10 seconds is recommended between two 10G SAT iterations or between two SLA runs (serial run).

  • A combination of untagged and default should never be configured on an interface for launching 10G SLA session. 10G SAT on encapsulation default does not work when encapsulation untagged is configured on the interface.

  • Even with 10G SAT, maximum FPGA available is 1G. 10G SAT rate is achieved by generating the packets in FPGA (upto 1 Gbps) and multiplying it by 10 on the hardware. Hence, a maximum of 1G FPGA is only available for all processes including BFD, SAT, NetFlow, and so on So, crossing the 1G cumulative threshold in FPGA causes flaps on the various interfaces that involve FPGA.

  • 10G SAT is not supported over VRF and Port-Channel interfaces.

  • SADT 10G session uses a shadow session with given MAC + 1 (0011.1111.2222 to 0011.1111.2223).

  • As 10G internal loopback is not supported, the router should have the external ELB (loopback) enabled.

  • 10G SADT internal is supports only Xconnect EFP and Plain EFP.

  • 10G SADT is not supported on L2VFI (Virtual Forwarding Interface) and local connect.

  • 10G SADT Color-aware configurations are not supported.

Restrictions for SAT Two-Way Sessions on EFP Xconnect on the Cisco RSP2 Module

  • For operations with EFP using XConnect, the rewrite ingress tag pop 1 symmetric command is not supported for two-way sessions when Class of Service (COS) value is a part of the packet profile.

  • For operations with EFP using XConnect, the rewrite command is not supported when Class of Service (COS) value is configured for the SLA.

  • For EVC with XConnect targets, CoS marking based on color for the color-aware cases is performed on the outer layer 2 header VLAN tags (if applicable). As a result, this marking should be retained across the network so that it is available on the packet, which is received at the remote end (passive measurement mode) or the same end after loopback at the remote end (two-way mode). If this CoS marking is not retained, there is no way identifying the color of the different packets and perform color-aware measurement.

  • Color-aware two-way sessions measurement is not supported for the restrictions listed above.

Restrictions on Cisco RSP3 Module for ASIC Based SAT

The following restrictions are applicable only for Cisco RSP3 Module:

  • The Tx and Rx counters are not synchronized during aggregation interval.

  • Traffic generation and measurement on target Bridge-domain, layer 3 interfaces, MPLS PWs, and BDI are not supported.

  • A maximum of four concurrent sessions are supported.

  • Each session should run on a different bridge-domain with unique packet VLAN parameters.

  • Color aware statistics are not supported.

  • EFP port-channel is not supported.

  • On target type EFP, bridge-domain specific features like L2PT, CEM, CFM, G.8032, STP, RSTP, and MSTP are not supported.

  • Target type EFP should not have any ingress or egress QoS applied on it. No port level QoS should be present.

  • Delay and jitter are not supported.

  • IMIX packet type is not supported, if configured, it will generate 64 bytes of packets.

  • Maximum traffic generation/measurement time is 11 hours.

  • If SPAN is configured, there is double Rx counters in statistics for external mode and double Tx counters in statistics for internal mode.

  • Traffic is not generated for priority tag (VLAN 0).

  • On test EFP/interface Shutdown, the test packets do not egress out of any interface on the device, and after unshut, the traffic does not resume to egress. The test has to be restarted.

  • Test on TEFP is not supported.

  • Double tag packet with outer and inner COS and rewrite POP1 is not supported.

  • Double tag packet with outer and inner COS and EFP with two VLAN and rewrite POP2 is not supported.

  • Only half of the line-rate (interface rate) is supported on a two-way session in internal mode. This limitation is not applicable for passive measurement and generator only sessions.

  • The service instance statistics on EFP, on which the internal session runs, has double the actual output packet count (synthetic packets are accounted twice.)

  • For higher step rate (1G,10G) Tx and Rx counters may not be accurate. A maximum of 10 Gbps is supported.

  • Configured step rate will not be the same as overall throughput, it varies based on the configured packet size.

  • Tx and Rx bytes may not be the same in show ip sla <> statistics CLI, though Tx and Rx packet are same.

  • There is no check if the destination MAC address is configured as all zero (0000.0000.0000) in IP SLA session.

Restrictions on Cisco RSP3 Module for FPGA Based SAT

The following restrictions ae applicable only for Cisco RSP3 Module:

  • For two-way sessions, source MAC address (last 2 bytes) of configured IP SLA sessions should be unique.

  • For passive measurement sessions, destination MAC address (last 2 bytes) of configured IP SLA sessions should be unique.

  • If a source MAC address is not confgured and if free unique MAC addresses are not available in the MAC pool on the node then the IP SLA schedule/restart CLI will stop with proper console logs and the IP SLA session with unique source mac specified by IP SLA configuration has to be initiated.

  • PPS may not match exactly.

  • FPGA supports a minimum of 16 Kbps and a maximum of 10 Gbps. FPGA cannot generate traffic with 100 percent accuracy. There may be a little difference between configured bandwidth and actual bandwidth.

  • For external direction SADT session, Rx and Tx packet count are same but Rx bytes and Tx bytes may not match exactly if the target EFP is configured with a rewrite action.

  • In some scenarios, SLA statistics collection is delayed by 1 second. This may impact the overall throughput.

  • Color aware statistics do not work if BDI is present for the bridge domain.

  • Dynamic modification is not supported while the session is running.

  • VLAN should be configured at the target interface in the SLA session. If the VLAN is not part of the interface configuration, packets are not handled properly.

  • If the outer VLAN is not specified but the inner VLAN is specified for the target EFP, by default the outer VLAN is 4095, the outer COS is 7, and the CFI is 1. If both the outer and the inner VLAN is not specified, the VLAN tags are fetched from the EFP.

  • The outer VLAN is required for the target TEFP.

  • Color-aware SADT is not supported on Cisco RSP3-200 module.

  • SADT supports only two rate three color policy.

  • Starting with Cisco IOS XE Release 16.6.1, for Cisco NCS 4216 routers, do not use any IM on slot 14 with FS or default mode. For Cisco NCS 4206 routers, do not use 8X10 Gigabit on slot 2 with SADT.

Note

The scale limit with the combination of Color-Aware and Color Blind IP SLA depends on the number of TCAM entries that the combination of SAT sessions consume. The Color-Aware session takes 3 entries for each session and the Color Blind consumes 1 entry for each session. Hence, the maximum scale for Color-Aware sessions is 15 ( 3 * 5 = 15 entries) and that for the Color Blind sessions is 15 (15 * 1 = 15 entries). Combination of Color-Aware and Color Blind depends on the number of TCAM entries consumed by the SAT profile and it is limited to entries.


Note

If a 10G SADT session is running then no other 1G or 10G session can be started on the Cisco RSP2 Module.

SADT Overhead Accounting

FPGA measures the following parameters for SADT:

  • Throughput

  • Frame Loss

  • Jitter

  • Delay

FPGA has the capability to generate and measure only 1Gbps traffic rate and hence maximum throughput cannot be achieved.

The following table shows the packet size and the maximum rate that can be achieved.

To overcome this limitation, use the platform y1564 shadow-session-enable command to replicate the packets 10 times in FPGA.

Restrictions

  • The platform y1564 shadow-session-enable command does not work in HA setup.

  • While using platform y1564 shadow-session-enable command, SADT session uses a shadow session with the given MAC + 1 (for example, 0011.1111.2222 to 0011.1111.2223). Hence source MAC and destination MAC must not be in consecutive numbers.

  • Use external Ethernet data plane loopback (ELB) for this feature as 1G internal loopback is not supported.

  • 1G internal SADT only supports EFP cross connect EFP.

  • 1G SADT is not supported on local connect and layer 2 VFI.

  • Color-aware configurations are not supported on 1G SADT.

  • 1G SADT can only be configured in two-way mode.

  • 1G SADT target type is only supported on access EFP.

  • A combination of 1G and 10G SADT sessions cannot be performed in parallel. Also, two 10G SADT sessions cannot be performed in parallel.

  • SADT statistics can only be validated after SADT operation is complete.

  • Layer 3 packets are not supported when SADT overhead accounting is enabled.

  • You should configure the parameters that are only related to layer 2 for a packet profile.

  • Overall throughput value slightly differs the rate step value.

  • Multiple rate steps of a single command should be added in an incremental order.

  • While QoS egress shaper policy is applied on the same SAT interface with 1G SADT, SAT traffic generation is affected based on the shaper value. There is no effect on the traffic when inbound policer-based policy is applied on the same SAT interface.

  • Broadcast and multicast destination MAC are not supported.

  • You should define the rate-steps upper limits of SADT to provide bandwidth to BFD and avoid the OSPF flaps.

  • Online Insertion and Removal (OIR) and Stateful Switchover (SSO) are not supported. SLA session must be stopped and re-started manually after these triggers are generated.

  • SADT SLA session and ELB on the same service instance of an interface are not supported.

  • 1G SADT on encapsulation default does not work when untagged encapsulation is configured on the interface.

  • 1G SADT is not supported on VRF and Port-Channel interfaces.

Configuring SADT Overhead Accounting

To configure SADT Overhead Accounting:
enable
configure terminal
platform y1564 shadow-session-enable
To remove the configuration:
enable
configure terminal
no platform y1564 shadow-session-enable

Configurable EMIX Packet Size

EMIX patterns are to be specified by the size designator for each frame in the repeating pattern. The following table is an example of the EMIX test profile.

Starting with Cisco IOS XE Release 16.12.4, EMIX packet size (default abceg pattern) is supported. For EMIX traffic, ITU-T Rec. Y.1564 packet sizes of 64, 128, 256, 1024, and 1518 bytes are supported.

The following table shows the configurable packet size patterns. You must specify the EMIX patterns using the size designator for each frame in the repeating pattern. For example, in the above table, you can specify an eight-frame repeating pattern as follows:
