Verifying the MQC Configuration

Verifying the MQC Configuration

Procedure

  • Run the display traffic classifier [ classifier-name ] command to check the traffic classifier configuration.
  • Run the display traffic behavior [ behavior-name ] command to check the traffic behavior configuration on the device.
  • Run the display traffic policy [ policy-name [ classifier classifier-name ] ] command to check the traffic policy configuration.

  • Run the display traffic-policy applied-record [ policy-name ] [ global [ slot slot-id ] | interface interface-type interface-number | vlan vlan-id | vsi vsi-name | vpn-instance vpn-instance-name | qos group group-id | bridge-domain bd-id ] [ inbound | outbound ] command to check the application records of a specified traffic policy.

    NOTE:

    The CE12800E does not support the vsi vsi-name parameter.

  • Run the display system tcam fail-record [ slot slot-id ] command to display TCAM delivery failures.
  • Run the display system tcam service brief [ slot slot-id ] command to display the group index and rule count occupied by different services.
  • Run the display system tcam service { cpcar slot slot-id | service-name slot slot-id [ chip chip-id ] } command to display IDs of entries delivered by services on the specified chip or in the specified slot.
  • Run one of the following commands to display data of a traffic policy that has been applied:
    • display system tcam service traffic-policy { global | vlan vlan-id | interface interface-type interface-number | vsi vsi-name | vpn-instance vpn-instance-name | qos group group-id | bridge-domain bd-id } policy-name { inbound | outbound } [ slot slot-id [ chip chip-id ] ]
      NOTE:

      The CE12800E does not support the vsi vsi-name parameter.

    • display system tcam service traffic-policy slot slot-id policy-name { inbound | outbound } [ chip chip-id ]
  • (For the CE12800) Run the display system tcam match-rules slot slot-id [ [ ingress | egress | group group-id ] | [ chip chip-id ] ] * command to display matched entries.
  • (For the CE12800E) Run the display system tcam match-rules slot slot-id chip chip-id index index-id command to display matched entries.
