# Monitoring ATM

This section explains how to set a statistics baseline, display bit rate and packet rate statistics for ATM virtual circuits (VCs), and use the show commands to view your ATM configuration and monitor ATM VCs and VPs.

| Note: The E120 and E320 routers output for monitor and show commands is identical to output from other E Series routers, except that the E120 and E320 routers output also includes information about the adapter identifier in the interface specifier (slot/adapter/port).

## Setting Statistics Baselines

You can set a statistics baseline for ATM interfaces, ATM virtual circuits, and ATM virtual paths configured on the router.

baseline atm vp interface

- Use to set a statistics baseline for an ATM virtual path (VP) interface.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
- To set the baseline for an ATM VP, specify the VPI. The numeric range of the VPI depends on the line module capabilities and current configuration.
- To display baseline statistics, use the delta keyword with ATM show commands.
- Examples
  `
  host1#baseline atm vp interface atm 12/0 0
  host1#baseline atm vp interface atm 5/0/0 1
  `
- There is no no version.
- See baseline atm vp interface.

baseline interface atm

- Use to set a statistics baseline for ATM interfaces or a specific virtual circuit.
- The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
- To set the baseline for a circuit, specify a VCD in the range 1–2147483647.
- To set the baseline on an interface, omit the VCD.
- To display baseline statistics, use the delta keyword with ATM show commands.
- Examples
  `
  host1#baseline interface atm 9/1 123
  host1#baseline interface atm 5/0/0 123
  `
- There is no no version.
- See baseline interface.

## Displaying Interface Rate Statistics for ATM VCs and ATM VPs

You can use the following commands to display bit rate and packet rate statistics over a specified time interval for one or more ATM virtual circuits (VCs) or virtual paths (VPs) configured on the router.

- To monitor the data rate for ATM VCs, use the monitor atm vc command.
- To monitor the data rate for ATM VPs, use the monitor atm vp command.

To monitor the data rate for ATM VCs and ATM VPs:

1. Log in to the router by using a local console session or a virtual terminal (vty) session (such as a Telnet session).

   While you use the monitor atm vc command or the monitor atm vp command, you must keep the console or terminal session open. You cannot issue any other commands during the session.

   For information about logging in to the router, see section Accessing the CLI in JUNOSe System Basics Configuration Guide.

2. Access User Exec mode or Privileged Exec mode.

   For information, see section Accessing Command Modes in JUNOSe System Basics Configuration Guide.

3. Specify the interface identifier and VCD (for each ATM VC) or VPI (for each ATM VP) that you want to monitor. For information about specifying an ATM interface, see Interface Types and Specifiers in JUNOSe Command Reference Guide.
   `
   host1#monitor atm vc atm 12/0 1 atm 8/0 1 display-time-of-day
   host1#monitor atm vp atm 12/0 0 atm 12/0 1 load-interval 15 display-time-of-day
   `

   By default, the router uses a 5-second time interval between polls to calculate bit rates and packet rates for each specified VC or VP. Optionally, you can use the load-interval keyword to specify a nondefault time interval in the range 5–30 seconds (for ATM VCs) or 5–300 seconds (for ATM VPs).

   You can also include the optional display-time-of-day keyword to show the time of day at which the router gathers statistics for each interval. Displaying the time of day enables you to monitor when a particular VC or VP is underutilized or overutilized.

4. Review the command output.

   The monitor atm vc command and monitor atm vp command display similar information, except that the monitor atm vc command displays the VCD for each interface and the monitor atm vp command displays the VPI for each interface.

   The router polls the statistics of each VC or VP identified in the command at the specified load interval to calculate and display bit rate and packet rate statistics. The first line of output for each interface always displays 0 (zero) for the number of seconds between polls, and dashes (--/--) in the Input bps/pps and Output bps/pps columns. These values indicate that the router initially takes a baseline for each interface against which to measure subsequent statistics. The router continues to display subsequent lines of output for each interface at the specified load interval until you press Ctrl+c to stop the command.

   For a description of the fields in the command display, see monitor atm vc and monitor atm vp.

5. If you remove an ATM interface or (for VCs) an ATM 1483 subinterface while you are monitoring one or more VCs or VPs that reside on the deleted interface, press Ctrl+c to stop the monitor atm vc command or monitor atm vp command, and then restart the command to ensure accurate interface rate statistics are displayed.

   If you leave the monitor atm vc command or monitor atm vp command running after you remove the interface, the command displays undefined or inaccurate statistics for the VC or VP on the interface that has been removed. The display of undefined or inaccurate statistics can result when you remove the interface by issuing either the no interface atm command or slot erase command, and can continue even after you recreate the interface with the same VC or VP configuration.

6. When you are finished monitoring, press Ctrl+c to stop the monitor atm vc command or monitor atm vp command.

- See show atm ping.

show atm subinterface

- Use to display the current state of all ATM subinterfaces, all ATM subinterfaces configured on a specified ATM physical interface, or a specific ATM subinterface.
- To specify an ATM subinterface for ERX7xx models, ERX14xx models, and ERX310 router, use the slot/port.subinterface format.
  - slot—Number of the chassis slot
  - port—Port number on the I/O module
  - subinterface—Number of the subinterface in the range 1–2147483647
- To specify an ATM subinterface for the E120 and E320 routers, use the slot/adapter/port.subinterface format.
  - slot—Number of the chassis slot
  - adapter—Identifier for the IOA within the E320 chassis, either 0 or 1, where:
    - 0 indicates that the IOA is installed in the right IOA bay (E120 router) or the upper IOA bay (E320 router).
    - 1 indicates that the IOA is installed in the left IOA bay (E120 router) or the lower IOA bay (E320 router).
  - port—Port number on the IOA
  - subinterface—Number of the subinterface in the range 1–2147483647
- To display brief summary information for all ATM subinterfaces, or for ATM subinterfaces configured on a specified ATM physical interface, use the summary keyword.
- To display status information only for ATM subinterfaces with a specific operating status, use the status keyword with one of the following status values. (See the Status field description for an explanation of these values.)
  - dormant
  - dormantLockout
  - down
  - lowerLayerDown
  - notPresent
  - up
- To display the current state of an ATM subinterface created on the PVC with the specified VPI and VCI values, use the atm slot/port/vpi/vci format (for ERX7xx models, ERX14xx models, and ERX310 router) or the slot/adapter/port/vpi/vci format (for E120 and E320 routers) to identify the ATM subinterface (Example 5).

  | Note: You can use the atm slot/port/vpi/vci format as an alternative to the atm slot/port.subinterface format with the specific show interface and show subinterface commands to monitor all ATM 1483 subinterfaces (except NBMA interfaces) as well as the upper-layer interfaces configured over an ATM 1483 subinterface. You cannot, however, use the atm slot/port/vpi/vci format to create or modify an ATM 1483 subinterface. These guidelines also apply to E120 and E320 routers when you use the atm slot/adapter/port/vpi/vci format as an alternative to the atm slot/adapter/port.subinterface format.

- For more information, see Creating a Basic Configuration.
- Field descriptions
  - Interface—Interface identifier
  - ATM-Prot—One of the following ATM protocol types:
    - RFC-1483—Multiprotocol encapsulation over AAL5
    - NBMA—Nonbroadcast multiaccess interface

  - Circuit Type—Type of circuit: PVC
  - Encap—Administered encapsulation method based on what was configured with the atm pvc command
  - MTU—Maximum transmission unit size for the interface
  - Status—One of the following ATM 1483 subinterface states:
    - absent—Represents the notPresent state and indicates that, although the SRP detects the ATM 1483 subinterface, the module on which the subinterface resides has not completed booting up, has failed, or is disabled.
    - dormant—Indicates that the ATM 1483 subinterface is performing autodetection of one or more upper-layer encapsulation types and is waiting to receive a packet of that type on a lower-layer interface. An ATM 1483 subinterface transitions from the dormant state to the up state when the router receives a valid packet of the specified encapsulation type on the interface.
    - dormantLockout—Indicates that a dormant ATM 1483 subinterface has one or more upper-layer encapsulation types currently undergoing encapsulation type lockout. An ATM 1483 subinterface transitions from the dormantLockout state to the dormant state when the lockout time expires for all upper-layer encapsulation types undergoing lockout. An ATM 1483 subinterface transitions from the dormantLockout state to the up state when the router receives a valid packet for an encapsulation type that is configured for autodetection but is not undergoing lockout.
    - down—Indicates that the ATM 1483 subinterface is administratively disabled or has a circuit that is down or not configured.
    - lowerLayerDown—Indicates that a lower-layer interface below the ATM 1483 subinterface is down.
    - up—Indicates that the ATM 1483 subinterface is up and able to transfer data. For an ATM 1483 subinterface that supports one or more dynamic upper-layer interfaces, indicates that the router has created the dynamic upper-layer interface or is in the process of creating it.
  - Interface Type—Type of ATM 1483 subinterface: dynamic or static
  - Auto configure status—Setting of the autoconfiguration feature
    - dynamic—Autodetection is on; the router automatically detects the next upper interface
    - static—Autodetection is off
  - Auto configure interface(s)—Types of dynamic upper interfaces configured with the auto-configure command: bridged Ethernet, IP, PPP, or PPPoE
  - Detected 1483 encapsulation—If the encapsulation type is set to aal5autoconfig, displays the 1483 encapsulation type detected on the subinterface (displays AUTO until a packet is detected)
  - Detected dynamic interface—Type of dynamic upper interface detected during autoconfiguration: bridged Ethernet, IP, PPP, PPPoE, or (if no packet has been received) none
  - Interface types in lockout—Encapsulation types currently experiencing lockout: bridged Ethernet, IP, PPP, PPPoE, or none
  - Lockout state (seconds)—Settings of encapsulation type lockout for the upper-layer encapsulation type indicated
    - Min—Minimum lockout time, in seconds
    - Max—Maximum lockout time, in seconds
    - Current—Current lockout time, in seconds; displays 0 (zero) if lockout is not occurring
    - Elapsed—Time elapsed into the lockout time, in seconds; displays 0 (zero) if lockout is not occurring
    - Next—Lockout time for the router to use for the next lockout event, in seconds
  - Assigned profile—For each dynamic interface type, indicates whether or not a profile is assigned and, if assigned, displays the profile name
