show rsvp interface

Syntax

Syntax (EX Series Switches)

Description

Display the status of Resource Reservation Protocol (RSVP)-enabled interfaces and packet statistics. The RSVP input/input module collects statistics for certain events on a per-interface basis. Most of these events were tracked on a routing-instance basis in Junos OS releases earlier than Release 17.2. The show rsvp interface detail command displays these event counters under the Events section of the output only when the values of these fields are higher than zero. These statistics are also maintained at the global level (per routing-instance) and are also displayed in the output of the show rsvp statistics command.

Options

none

Display standard information about the status of RSVP-enabled interfaces and packet statistics.

brief | detail | extensive | link-management

(Optional) Display the specified level of output.

instance instance-name

(Optional) Display RSVP status information for the specified instance. If instance-name is omitted, RSVP status information is displayed for the master instance.

link-management

(Optional) Use the link-management option to display the control peers and corresponding TE-link information created by the Link Management Protocol (LMP).

logical-system (all | logical-system-name)

(Optional) Perform this operation on all logical systems or on a particular logical system.

Output Fields

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

Table 1: show rsvp interface Output Fields

Field Name

Field Description

Level of Output

RSVP interface

Number of interfaces on which RSVP is active. Each interface has one line of output.

All levels

Interface

Name of the interface.

All levels

Index

Index of the interface.

detail

State

State of the interface.

  • Disabled—No traffic engineering information is displayed.

  • Down—Interface is not operational.

  • Enabled—Displays traffic engineering information.

  • Up—Interface is operational.

All levels

NoAuthentication

Interface does not support RSVP authentication.

detail

NoAggregate

Interface does not support refresh reduction.

detail

NoReliable

Interface does not support refresh reduction message ID extension.

detail

NoLinkProtection

Interface does not support link protection.

detail

HelloInterval

Frequency at which RSVP hellos are sent on this interface (in seconds).

Prior to Junos OS Release 18.2R2, when the no-interface-hello statement is configured under the [edit protocols rsvp] hierarchy, and there is no interface-specific configuration for the hello interval, the HelloInteval output field displayed the default hello interval time of 9 seconds. Starting in Junos OS Release 18.2R2, with a similar configuration, the HelloInterval output field displays 0 as the hello interval.

detail

Address

IP address of the local interface.

detail

Active control channel

Next-hop link address to transmit messages.

None specified

TElink

Traffic-engineered links that are managed by the peer they are associated with.

None specified

Active resv

Number of reservations that are actively reserving bandwidth on the interface.

All levels

PreemptionCnt

Number of times an RSVP session was preempted on this interface.

detail

Update threshold

Percentage change in reserved bandwidth to trigger an IGP update.

detail

Subscription

User-configured subscription factor.

All levels

Actual

Available RSVP bandwidth that is recalculated after considering SPRING bandwidth utilization.

extensive

bc number

Bandwidth allocated for the specified bandwidth constraint.

extensive

ct number

Bandwidth allocated for the specified class type.

extensive

Static BW

Total interface bandwidth, in bps.

All levels

Available BW

Amount of bandwidth that RSVP is allowed to reserve, in bps. It is equal to (static bandwidth * subscription factor).

al levels

Reserved BW

Currently reserved bandwidth, in bps.

All levels

SoftPreemptionCnt

Number of times a soft preemption occurred on this interface. This number is not included in the PreemptionCnt value.

detail

Overbooked BW

Currently overbooked bandwidth, in bps, by class type (ct0 through ct3).

detail

Highwater mark

Highest bandwidth that has ever been reserved on this interface, in bps.

brief

PacketType

Type of RSVP packet.

detail

Total Sent

Total number of packets sent.

detail

Total Received

Total number of packets received since RSVP was enabled.

detail

Last 5 seconds Sent

Number of packets sent in the last 5 seconds.

detail

Last 5 seconds Received

Number of packets received in the last 5 seconds.

detail

Path

Statistics about Path messages, which are sent from the RSVP sender along the data paths and store path state information in each node along the path.

detail

PathErr

Statistics about PathErr messages, which are advisory messages that are sent upstream to the sender.

detail

PathTear

Statistics about PathTear messages, which remove path states and dependent reservation states in any routers along a path.

detail

Resv

Statistics about Resv messages, which are sent from the RSVP receiver along the data paths and store reservation state information in each node along the path.

detail

ResvErr

Statistics about ResvErr messages, which are advisory messages that are sent when an attempt to establish a reservation fails.

detail

ResvTear

Statistics about ResvTear messages, which remove reservation states along a path.

detail

Hello

Number of RSVP hello packets that have been sent to and received from the neighbor.

detail

Ack

Acknowledge message for refresh reductions.

detail

Srefresh

Summary refresh messages.

detail

EndtoEnd RSVP

Statistics for the number of end-to-end RSVP messages sent.

detail

Queue

CoS transmit queue number and its associated forwarding class designation.

extensive

TxRate

Configured bandwidth in Mbps and configured bandwidth as a percentage of the specified queue.

extensive

Priority

Weight of the queue relative to other configured queues, in percentage.

extensive

queue-priority-value

Low, High, None, or Exact. None indicates no rate limiting. Exact indicates the queue transmits at the configured rate only.

extensive

subscriptionpriority percentage

Indicates per-priority subscription percentage.
