Monitoring Upper-Layer Dynamic Interfaces and Profiles

You can use the show commands described in this section to monitor configurations created with dynamic interfaces and profiles.

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).

See show atm aal5 interface.

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 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 in Configuring ATM .
Field descriptions

  - 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.
