Configuring the Ingress Node

Configuring the Ingress Node

Context

In the IOAM system, OAM information or actions about the local hop need to be configured on the ingress, transit, and egress nodes. This section describes how to configure the ingress node.

NOTE:

The CE8850-64CQ-EI can function only as a transit node but not an ingress or egress node.

The same value of header header-value must be configured on the ingress, transit, and egress nodes. Otherwise, IOAM traffic fails to be forwarded.

Procedure

  1. Enable the IOAM function to collect and copy service packets.
    1. Run system-view

      The system view is displayed.

    2. Run traffic classifier classifier-name [ type { and | or } ]

      A traffic classifier is created and the traffic classifier view is displayed, or the view of an existing traffic classifier is displayed.

    3. Run if-match

      Matching rules are defined for the traffic classifier.

      For details about matching rules in a traffic classifier, see "Configuring a Traffic Classifier" in "MQC Configuration" of the CloudEngine 8800, 7800, 6800, and 5800 Series Switches QoS Configuration Guide.

    4. Run quit

      Exit from the traffic classifier view.

    5. Run traffic behavior behavior-name

      A traffic behavior is created and the traffic behavior view is displayed, or the view of an existing traffic behavior is displayed.

    6. Run ioam enable [ sampling-rate sampling-rate ]

      IOAM is enabled to collect and copy service packets.

      The default value of sampling-rate is 1, indicating that all matched packets are collected and copied. If sampling-rate is specified in the command, packets are collected and copied at the specified sampling rate.

      When the CE6865EI acts as an ingress node, the IOAM function needs to be enabled. The IOAM function and the interface split function of 100GEx/0/3 (x indicates the stack ID of the switch) are mutually exclusive and cannot be configured together. When you configure the IOAM function after canceling the interface split function of 100GEx/0/3, restart the switch for the IOAM function to take effect.

      When the CE8868EI or CE8861EI acts as an ingress node, the IOAM function needs to be enabled. The IOAM function and the interface split function of some interfaces are mutually exclusive and cannot be configured together. When you configure the IOAM function after canceling the interface split function of these interfaces, restart the switch for the IOAM function to take effect. The involved interfaces include 100GEx/1/2 of the CE88-D24S2CQ or CE88-D24S2CQ-U, 100GEx/1/1 of the CE88-D24T2CQ, 100GEx/1/8 of the CE88-D8CQ, and 40GEx/1/13 and 40GEx/1/14 of the CE88-D16Q.

    7. Run quit

      Exit from the traffic behavior view.

    8. Run traffic policy policy-name

      A traffic policy is created and the traffic policy view is displayed, or the view of an existing traffic policy is displayed.

    9. Run classifier classifier-name behavior behavior-name [ precedence precedence-value ]

      A traffic behavior is bound to a traffic classifier in a traffic policy.

    10. Run quit

      Exit from the traffic policy view.

    11. Run display traffic-policy pre-state { global [ slot slot-id ] | interface { interface-type interface-number } | vlan vlan-id | bridge-domain bd-id } policy-name { inbound | outbound }

      The resources occupied by the traffic policy to be applied are displayed to check whether the corresponding traffic policy can be successfully applied after the configuration is committed.

    12. Apply a traffic policy to a physical interface, an Eth-Trunk, or the system.

      • Apply a traffic policy to a physical interface or an Eth-Trunk.
        1. Run interface interface-type interface-number

          The interface view is displayed.

        2. Run traffic-policy policy-name { inbound | outbound }

          A traffic policy is applied to the interface.

        3. Run quit

          Exit from the interface view.

      • Apply a traffic policy to the system.
        1. Run traffic-policy policy-name global [ slot slot-id ] { inbound | outbound }

          A traffic policy is applied to the system.

  2. Run ioam [ header header-value ] [ device-id { number | ip-address } ] add-metadata

    OAM information about the local hop is configured.

  3. (Optional) Configure specified interfaces to drop outgoing IOAM packets.
    1. Run interface interface-type interface-number

      The interface view is displayed.

    2. Run ioam [ header header-value ] drop

      The interface is configured to drop outgoing IOAM packets.

      On an interface that does not need to transmit IOAM packets, you can configure the interface to drop IOAM packets to prevent IOAM packets from being incorrectly forwarded or flooded.

    3. Run quit

      Exit from the interface view.

  4. Run commit

    The configuration is committed.
