ATM Interface Operational Mode Commands

[Contents] [Prev] [Next] [Index] [Report an Error]

Table 78 summarizes the command-line interface (CLI) commands you can use to monitor and troubleshoot Asynchronous Transfer Mode (ATM) interfaces on M-series and T-series routing platforms, and ATM-over-asymmetrical digital subscriber line (ADSL) and ATM-over-symmetric high-speed digital subscriber line (SHDSL) interfaces on the J-series routing platform. An ATM-over-ADSL interface and an ATM-over-SHDSL interface is configured over an underlying ATM interface.

Table 78: ATM Interface Operational Mode Commands

Task	Command
Display status information about ATM interfaces.	show interfaces (ATM)
Display status information about ATM-over-ADSL interfaces.	show interfaces (ATM-over-ADSL)
Display status information about ATM-over-SHDSL interfaces.	show interfaces (ATM-over-SHDSL)

ATM-over-ADSL interfaces are used to transport Point-to-Point Protocol over Ethernet (PPPoE) frames or Point-to-Point Protocol over ATM (PPPoA) frames over an ADSL loop and a digital subscriber line access multiplexer (DSLAM). Both PPPoE and PPPoA connect multiple hosts on an Ethernet LAN to a remote site through the J-series Services Router. The hosts share a common digital subscriber line (DSL), a cable modem, or a wireless connection to the Internet.

ATM-over-SHDSL interfaces are used to transport network traffic through a point-to-point connection to a DSL access multiplexer (DSLAM).

Note: For information about monitoring and troubleshooting PPPoE interfaces (pp0), which are used in conjunction with ATM-over-ADSL interfaces, see PPPoE Interface Operational Mode Commands For more information about monitoring and troubleshooting ATM interfaces, see “Investigate ATM Interfaces” in the JUNOS Interfaces Network Operations Guide.
