Configuring Single-ended Frame Loss Measurement in VLAN Networking

In VLAN networking, CFM is enabled. CCMs are not used to monitor link connectivity, preventing them from using a lot of network bandwidth resources. If frame loss measurement needs to be performed for a link, single-ended frame loss measurement can be configured to monitor the quality of the link.

Single-ended frame loss measurement in VLAN networking can be either on-demand or proactive. On-demand single-ended frame loss measurement is manually initiated for diagnosis of frame loss in a limited time. It can be singular or periodic measurement. Proactive single-ended frame loss measurement is performed continuously to permit proactive reporting of frame loss or performance results.

Configuring Single-ended SLM in VLAN Networking

This section describes how to configure single-ended synthetic loss measurement (SLM) in virtual local area network (VLAN) networking. To collect performance statistics for frame loss on point-to-multipoint or multipoint-to-multipoint links, deploy single-ended SLM, which helps monitor link quality.

Context

In VLAN networking, single-ended SLM includes on-demand and proactive SLM functions. On-demand SLM collects single-ended frame loss statistics at one or more specific times for diagnosis.

Configuring the ETH-Test Function for a VLAN

The ETH-test function is short for Ethernet test signal. ETH-test instances are performed for a unidirectional on-demand service or during an on-demand-service interruption to calculate parameters, including the maximum bandwidth, frame loss ratio, and bit error rate.

Context

In Figure 6-45, MEP1 is configured on an AC interface of PE1, and MEP2 is configured on an AC interface of PE2. MEP1 initiates an ETH-test and sends test packets with a specified size and code type at a specified rate and interval. Then check the number of packets MEP1 sends and the number of packets MEP2 receives. If MEP1 sends more packets than MEP2 receives, some packets have been dropped. Then MEP1 is configured to use the bisection method to continue the test and send test packets at a lower rate. The bisection method is used to send test packets at different rates between the upper and lower rate thresholds. The test process repeats until a maximum bandwidth is found when no packets are dropped in a test. In addition, check for bit errors on MEP2 that receives test packets.

Procedure

  1. Perform the following steps on PEs:

    1. Run system-view

      The system view is displayed.

    2. Run cfm enable

      CFM is enabled globally.

    3. Run cfm md md-name

      The MD view is displayed.

    4. Run ma ma-name

      The MA view is displayed.

    5. Run map vlan vlan-id

      The MA is associated with a VLAN.

    6. Run mep mep-id

      A MEP is configured.

    7. Run remote mep mep-id mep-id

      A RMEP is configured.

    8. Run eth-test enable mep mep-id

      The ETH-test function is enabled.

    9. Run eth-test start mep mep-id { mac mac-address | remote-mep mep-id } rate rate-value [ [ timeout timeout-value ] | [ pattern { zero-no-crc | zero-crc } ] | [ 8021p 8021p-value ] | [ packet-size packet-size-value ] | out-of-service { lck-level level-value } ] *

      The MEP is enabled to send test packets. The rate at which Eth-Test packets are sent is the L2 rate.

    10. (Optional) Run eth-test stop mep mep-id

      The MEP is disabled from sending test packets.

    11. Run commit

      The configuration is committed.

Configuring AIS

Configuring AIS prohibits a MEP in an MD of a higher level from sending the same alarm as that sent by a MEP in an MD of a lower level to the NMS.

Context

As shown in Figure 6-46, the MEPs configured on the access interfaces of CE1 and CE2 reside in level-6 MD1. The MEPs configured on PE1 and PE2 reside in level-3 MD2. When a fault occurs, a MEP in level-3 MD2 first detects the fault and sends an alarm to the NMS. After a certain period, a MEP in level-6 MD1 also detects the fault and sends the same alarm to the NMS. Therefore, the AIS function needs to be configured on the PEs to prohibit the MEP in the MD of a higher level from sending alarms to the NMS.
Figure 6-46 Networking diagram of configuring AIS in VLAN networking

Procedure

  1. Perform the following steps on a PE:

    1. Run system-view

      The system view is displayed.

    2. Run cfm md md-name

      The MD view is displayed.

    3. Run ma ma-name

      The MA view is displayed.

    4. Run map vlan vlan-id

      The MA is bound to the current VLAN.

    5. Run ais enable

      AIS is enabled for the current MA.

    6. (Optional) Run ais link-status

      AIS is configured to monitor interfaces in the current MA.

    7. (Optional) Run ais interval interval-value

      The interval at which AIS packets are sent is set.

      If the range of VLANs to which AIS packets are to be sent is set, setting the interval at which AIS packets are sent to 60s is recommended.

    8. Run ais level level-value

      The level of AIS packets to be sent is set.

    9. Run ais vlan { pe-vid pe-vid ce-vid { low-ce-vid [ to hig-ce-vid ] } &<1-10> | vid { low-vid [ to high-vid ] } &<1-10>} mep mep-id

      The range of VLANs to which AIS packets are to be sent is set.

  2. Perform the following steps on a CE:

    1. Run system-view

      The system view is displayed.

    2. Run cfm md md-name

      The MD view is displayed.

    3. Run ma ma-name

      The MA view is displayed.

    4. Run map vlan vlan-id

      The MA is bound to the current VLAN.

    5. Run ais enable

      AIS is enabled for the current MA.

    6. Run ais suppress-alarm

      Alarm suppression is enabled for the current MA.

      In an MD nesting scenario, if alarm suppression is enabled for the MD of a high level, a MEP in this MD does not send alarms that a MEP in an MD of a low level has sent to the NMS after receiving an AIS packet.

    7. Run mep alarm disable

      Disables the alarm reporting function of a specific alarm indication signal (AIS).

  3. Run commit

    The configuration is committed.

Checking the Configurations

  • Run the display cfm ma command on a PE to check information about MAs.

    The command output shows when the device receives the right AIS packets then the Sending Ais Packet field is displayed as Yes.

  • Run the display cfm ma command on a CE to check information about MAs.

    The command output shows that the Suppressing Alarms field is displayed as Yes.

Enabling the ETH-BN Receiving Function for a VLAN

When routing devices connect to microwave devices, enable the ETH-BN receiving function to implement association with the microwave bandwidth.

Context

On the network shown in Figure 6-47, the RTN links form a single chain and no intermediate services are on the chain.

Interface1 in this example is GE 0/1/0.


When planning ETH-BN, you must check that the service burst traffic is consistent with a device's buffer capability.
