show user-plane interfaces queue

Syntax

Description

Lists queue information for the specified BNG User Plane subscriber's interface name.

Options

none

Show detailed queue statistics for all physical interfaces.

forwarding class forwarding-class-name (Optional) Forwarding class name for this queue. Shows detailed statistics for the queue associated with the specified forwarding class.

Required Privilege Level

root

Output Fields

Table 1 lists the output fields for the show user-plane interfaces queue command. Output fields are listed in the approximate order in which they appear.

Table 1: show user-plane interfaces queue Output Fields

Field Name

Field Description

Queue

Queue number.

Forwarding classes

Forwarding class name.

Queued Packets

Number of packets queued to this queue.

For rate-limited interfaces hosted on MICs or MPCs only, this statistic does not include traffic dropped due to rate limiting. For more information, see Additional Information.

Queued Bytes

Number of bytes queued to this queue. The byte counts vary by interface hardware. For more information, see ../../../../../../junos/cli-reference/topics/ref/command/show-interfaces-queue.html#byte-count-by-pic-type-table.

For rate-limited interfaces hosted on MICs or MPCs only, this statistic does not include traffic dropped due to rate limiting. For more information, see Additional Information.

Transmitted Packets

Number of packets transmitted by this queue. When fragmentation occurs on the egress interface, the first set of packet counters shows the postfragmentation values. The second set of packet counters (displayed under the Packet Forwarding Engine Chassis Queues field) shows the prefragmentation values.

Transmitted Bytes

Number of bytes transmitted by this queue. The byte counts vary by interface hardware. .

Note:

On MX Series routers, this number can be inaccurate when you issue the command for a physical interface repeatedly and in quick succession, because the statistics for the child nodes are collected infrequently. Wait ten seconds between successive iterations to avoid this situation.

Note:

For Layer 2 statistics, see Additional Information

Tail-dropped packets

Number of packets dropped because of tail drop.

RL-dropped packets

Number of packets dropped due to rate limiting.

For rate-limited interfaces hosted on MICs, MPCs, and Enhanced Queuing DPCs only, this statistic is not included in the queued traffic statistics. For more information, see Additional Information.

RL-dropped bytes

Number of bytes dropped due to rate limiting.

For rate-limited interfaces hosted on MICs, MPCs, and Enhanced Queuing DPCs only, this statistic is not included in the queued traffic statistics. For more information, see Additional Information.

RED-dropped packets

Number of packets dropped because of random early detection (RED).

  • The output classifies dropped packets into the following categories:

    • Low—Number of low-loss priority packets dropped because of RED.

    • Medium-low—Number of medium-low loss priority packets dropped because of RED.

    • Medium-high—Number of medium-high loss priority packets dropped because of RED.

    • High—Number of high-loss priority packets dropped because of RED.

RED-dropped bytes

Number of bytes dropped because of RED. The byte counts vary by interface hardware. For more information, see .

  • The output classifies dropped bytes into the following categories:

    • Low, non-TCP—Number of low-loss priority non-TCP bytes dropped because of RED.

    • Low, TCP—Number of low-loss priority TCP bytes dropped because of RED.

    • High, non-TCP—Number of high-loss priority non-TCP bytes dropped because of RED.

    • High, TCP—Number of high-loss priority TCP bytes dropped because of RED.

ECN-CE packets

The number of packets that experienced congestion, either on a specific queue or on another device prior to being received.

ECN-CE bytes

The number of bytes that experienced congestion, either on a specific queue or on another device prior to being received.

Queue Buffer Usage:

  • Reserved buffer—The size of the memory buffer that is allocated for storing packets

  • Current—The amount of buffer memory that is currently in use on this queue.

Queue-depth bytes

Displays the amount of queue buffer that is in occupation at this instance. This is an indicator of the amount of data that is present in a queue at that point in time. The amount of data present is in the units of bytes.

Peak

Diplays the peak buffer occupancy for the queue while buffer-monitor-enable is enabled at the [edit chassis fpc slot-number traffic-manager] hierarchy level.

Last-packet enqueued

If packet-timestamp is enabled for an FPC, shows the day, date, time, and year in the format day-of-the-week month day-date hh:mm:ss yyyy when a packet was enqueued in the CoS queue. When the timestamp is aggregated across all active Packet Forwarding Engines, the latest timestamp for each CoS queue is reported.
