# Monitoring PPPoE

Use the commands described in this section to display information about PPPoE interfaces and subinterfaces.

You can set a statistics baseline for PPPoE interfaces, subinterfaces, and circuits using the baseline pppoe interface command.

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 chapter Command Line Interface in JUNOSe System Basics Configuration Guide for details.

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

baseline pppoe interface

- Use to set a statistics baseline for PPPoE interfaces, subinterfaces, and circuits.
- 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.
- You cannot set a baseline for groups of interfaces, subinterfaces, or circuits. You must set them one at a time.
- When baselining is requested, the time since the last baseline was set is displayed in hours:minutes:seconds or days/hours format. If a baseline has not been set, the message “No baseline has been set” is displayed instead.
- Use the optional delta keyword with PPPoE show commands to specify that baselined statistics will be shown.
- Examples
  `
  host1#baseline pppoe interface atm 2/0.1.1
  host1#baseline pppoe interface atm 2/0/0.1.1
  `
- There is no no version.
- See baseline pppoe interface.

show radius override

- Use to display the current override settings configured on the RADIUS client (LNS) for the NAS-IP-Address [4], NAS-Port-Id [87], Calling-Station-Id [31], and NAS-Identifier [32] RADIUS attributes.
- Field descriptions
  - nas-ip-addr—Override setting for the NAS-IP-Address attribute
  - nas-port-id—Override setting for the NAS-Port-Id attribute; value is remote-circuit-id if configured with radius override nas-port-id remote-circuit-id command
  - calling-station-id—Override setting for the Calling-Station-Id attribute; value is remote-circuit-id if configured with radius override calling-station-id remote-circuit-id command
  - nas-info—Virtual router that generates the NAS-IP-Address and NAS-Identifier attributes for AAA broadcast accounting packets; current virtual router or authentication virtual router
- Example

      host1#show radius override
      nas-ip-addr:        nas-ip-addr
      nas-port-id:        remote-circuit-id
      calling-station-id: remote-circuit-id
      nas-info:           from current virtual router

- See show radius override.

show radius remote-circuit-id-delimiter

- Use to display the delimiter character configured to set off components in the PPPoE remote circuit ID value captured from a DSLAM.
- The default delimiter character is #.
- Example

      host1#show radius remote-circuit-id-delimiter
      %

- See show radius remote-circuit-id-delimiter.

show radius remote-circuit-id-format

- Use to display the format configured for the PPPoE remote circuit ID value captured from a DSLAM.
- If the PPPoE remote circuit ID value is configured to include any or all of the agent-circuit-id, agent-remote-id, and nas-identifier components, the display lists the components included and the order in which they appear.
- If the PPPoE remote circuit ID value is configured to use the format for the dsl-forum-1 keyword of radius remote-circuit-id-format , the display indicates that this format is in effect.
- The default format is agent-circuit-ID.
- Example

      host1#show radius remote-circuit-id-format
      nas-identifier agent-circuit-id agent-remote-id

- See show radius remote-circuit-id-format.
