Monitoring ATM
This section shows how to assign text descriptions to ATM interfaces and virtual paths, 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 an alias to an interface, which allows that information to be displayed by other show commands.
atm aal5 description
- Use to assign a text description or alias to an ATM AAL5 interface.
- Use the show atm aal5 interface command 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.
- The description can be a maximum of 255 characters.
- Use the show atm subinterface command 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 ATM interface.
- The description can be a maximum of 255 characters and can include the # (pound sign) character.
- The first 32 characters of the ATM description are pushed out to RADIUS during authentication and accounting.
- Use the show atm interface command to display the description.
- Use the no version to remove the description or alias.
Assigning Descriptions to Virtual Paths
You can use the atm vp-description command to assign a text description to an individual VP on an ATM interface. The description that you configure for a specified VPI appears in the RADIUS Calling-Station-ID (CLID) attribute. As a result, the VP description can provide a convenient way to identify or group broadband access subscribers. (For more information about RADIUS and the CLID attribute, see JUNOSe Broadband Access Configuration Guide, Chapter 2, Configuring RADIUS Attributes.)
The VP description does not affect any existing descriptions configured for the ATM interface or ATM 1483 subinterface on which the VP resides. However, if you delete the ATM interface, the descriptions of all VPs residing on that interface are also deleted. In addition, if you decrease the VPI range by issuing the atm vc-per-vp command, the router deletes the descriptions of any VPs that are removed.
You can display the VP description by issuing the show atm vp-description command, as described in ATM show Commands later in this chapter. Although you need not configure a VP tunnel to specify a VP description, the router also displays the VP description in the output of the show atm vp-tunnel command.
atm vp-description
- Use to assign a text description to an individual VP on an ATM interface or subinterface.
- You must specify the VPI of the VP to which you want to assign the description.
- The description string can be a maximum of 32 characters.
- The VP description is stored in NVS and persists after a reboot.
- Use the show atm vp-description command to display the text description.
- Example
host1(config-if)#atm vp-description 2 vpi2Subscribers
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 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 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
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-description
- 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 JUNOSe System Basics Configuration Guide, Chapter 2, Command Line Interface.
