show interfaces queue

 

Syntax

Release Information

Command introduced in Junos OS Release 15.1X49-D30.

Description

Display class-of-service (CoS) queue information for physical interfaces.

Note

The queue depth information is only available on vSRX and SRX1500, SRX4100, SRX4200 and SRX4600 platforms.

Options

none—Show detailed CoS queue statistics for all physical interfaces.
both-ingress-egress—Display both ingress and egress queue statistics.
egress—Display egress queue statistics.
forwarding-class forwarding-class—(Optional) Forwarding class name for this queue. Show detailed CoS statistics for the queue that is associated with the specified forwarding class.
ingress—Display ingress queue statistics.
interface-name interface-name—(Optional) Show detailed CoS queue statistics for the specified interface.
l2-statistics—(Optional) Display Layer 2 statistics for MLPPP, FRF.15, and FRF.16 bundles.

Output Fields

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

Table 1: show interfaces queue Output Fields

Field Name

Field Description

Physical interface

Name of the physical interface.

Enabled

State of the interface. Possible values are described in the “Enabled Field” section under Common Output Fields Description.

Interface index

Index number of the physical interface. The number reflects the interface’s initialization sequence.

SNMP ifIndex

SNMP index number for the interface.

Forwarding classes supported

Total number of forwarding classes supported on the specified interface.

Forwarding classes in use

Total number of forwarding classes in use on the specified interface.

Egress queues supported

Total number of egress queues supported on the specified interface.

Egress queues in use

Total number of egress queues in use on the specified interface.

The following output fields are applicable to both the interface component and Packet Forwarding Engine component in the show interfaces queue command:

Queue

Queue number.

Forwarding classes

Forwarding class name.

Queued Packets

Number of packets in this queue.

Queued Bytes

Number of bytes in this queue.

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.

Tail-dropped packets

Number of packets dropped because of tail drop.

RL-dropped bytes

Number of bytes dropped because of rate limiting.

RED-dropped packets

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

RED-dropped bytes

Number of bytes dropped because of RED.

  • 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.

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

Current—The maximum number of bytes in this queue, that is currently in use on this queue.

Sample Output

show interfaces queue (vSRX)

 

The following truncated example shows the CoS queue sizes for queues 0, 1, and 3. Queue 1 has a queue buffer size (guaranteed allocated memory) of 9192 bytes.
