Configuring buffer allocation profiles for subinterfaces

Configure a buffer allocation profile for a subinterface

--{ candidate shared default }--[ ]--
# info with-context qos buffer-management buffer-allocation-profile subinterface-buffer-profile
    qos {
        buffer-management {
            buffer-allocation-profile subinterface-buffer-profile {
                queues {
                    queue af1 {
                        maximum-burst-size 256000
                    }
                    queue af2 {
                        maximum-burst-size 256000
                    }
                    queue best-effort {
                        maximum-burst-size 512000
                    }
                    queue expedited {
                        maximum-burst-size 128000
                    }
                    queue nc {
                        maximum-burst-size 28000
                    }
                }
            }
        }
    }

Configure subinterface queues and forwarding classes

The following example shows additional configuration for subinterface queues and forwarding classes associated with the preceding buffer allocation profile.

--{ candidate shared default }--[  ]--
# info with-context qos queues
    qos {
        queues {
            queue af1 {
                queue-index 1
            }
            queue af2 {
                queue-index 2
            }
            queue best-effort {
                queue-index 0
            }
            queue expedited {
                queue-index 6
            }
            queue nc {
                queue-index 7
            }
        }
    }

--{ candidate shared default }--[ qos forwarding-classes ]--
# info with-context qos forwarding-classes
    qos {
        forwarding-classes {
            forwarding-class af1 {
                output {
                    unicast-queue af1
                }
            }
            forwarding-class af2 {
                output {
                    unicast-queue af2
                }
            }
            forwarding-class be {
                output {
                    unicast-queue best-effort
                }
            }
            forwarding-class ef {
                output {
                    unicast-queue expedited
                }
            }
            forwarding-class nc {
                output {
                    unicast-queue nc
                }
            }
        }
    }
