Monitoring ATM

This section shows how to assign text descriptions to ATM interfaces, set a statistics baseline, and use the show commands to view your ATM configuration and monitor ATM interfaces.

Assigning Descriptions to Interfaces

You can use the description commands to assign a text description or alias to an interface, which allows that information to be picked up by other show commands.

    atm aal5 description

• Use to assign a text description or alias to an aal5 interface.
• Use the show atm aal5 interface to display the text description.
• Use the no version to remove the text description or alias.

    atm atm1483 description

• Use to assign a text description or alias to an ATM 1483 subinterface.
• Use the show atm subinterface to display the text description.
• Use the no version to remove the text description or alias.

    atm description

• Use to assign a text description or alias to the interface.
• Use the show atm interface command to display the text description.
• The first 32 characters of the ATM description are pushed out to RADIUS during authentication and accounting.
• Use the no version to remove the text description or alias.

Setting Statistics Baselines

You can set a statistics baseline for ATM interfaces or circuits using the baseline interface atm command.

    baseline interface atm

• Use to set a statistics baseline for ATM interfaces or a specific virtual circuit.
• The system 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 specify that baseline statistics are to be shown, use the delta keyword with ATM show commands.
• Example

host1#baseline atm interface atm 9/1 123

• There is no no version.

ATM show Commands

Use the following versions of the show atm command to view your ATM configuration and monitor ATM interfaces:

• show atm aal5 interface
• show atm interface
• show atm map
• show atm oam
• show atm ping
• show atm subinterface
• show atm vc
• show atm vc atm
• show atm vp-tunnel
• show mpls cross-connects atm
• show nbma arp

You can use the output filtering feature of the show command to include or exclude lines of output based on a text string you specify. See show Commands in ERX System Basics Configuration Guide, Chapter 2, Command Line Interface.

    show atm aal5 interface

• Use to display a configured ATM AAL5 interface.
• Field descriptions
