Monitoring MLPPP

Use the commands in this section to display information about MLPPP interfaces.

You can set a statistics baseline for MLPPP serial (member link) or bundle (multilink) interfaces using the baseline ppp command. Use the delta keyword with the show commands described below to display statistics with the baseline values subtracted.

After you configure multilink PPP, you can use the show ppp interface commands to display configuration and statistics information about MLPPP and MLPPP fragmentation and reassembly.

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. For details, see section show Commands in JUNOSe System Basics Configuration Guide.

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 ppp interface

Use to set a statistics baseline for PPP interfaces—including MLPPP interfaces, either individual serial (member link) interfaces or multilink (bundle) interfaces.
Use only the serial or mlppp keywords.
For serial interfaces, specify the interface location in the format slot/port:channel/subchannel for CT3 modules.
For MLPPP interfaces, specify the interface location as the name of the MLPPP bundle.
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.
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 was not set, the following message is displayed instead:
```
No baseline has been set
```
Use the optional delta keyword with MLPPP show commands to specify that baselined statistics are to be shown.
Examplehost1#baseline ppp interface serial 2/0:1/1
There is no no version.
See baseline ppp interface.

Sample Display Without Baseline

The following command displays PPP interface (including MLPPP interface) statistics without baselining:

show ppp interface mlppp

Use to display information about MLPPP interfaces.
You can display a great variety of information with this complex command. See the show ppp interface command in Configuring Point-to-Point Protocol, for more detailed information about the display options.
Use the show ppp interface command to display information about all PPP interfaces, including MLPPP interfaces.

    Note: For the LCP, IPCP, and OSINLCP negotiated options, the command displays a value of “none” if the option was not negotiated.
- LCP protocol configuration:
  - max-receive-unit—Controls negotiation of the local MRU option; value can be one of the following:
    - use lower layer—MRU of the layer below PPP defines the MRU to be negotiated

    - chap/pap—Negotiate CHAP, and if it is rejected, negotiate PAP
    - pap/chap—Negotiate PAP, and if it is rejected, negotiate CHAP
  - magic-number—Controls whether the local magic number is negotiated: enabled (negotiate), or disabled (do not negotiate)
  - magic-number-mismatch—Indicates whether the router is configured to ignore the LCP peer magic number and retain the PPP connection when the peer has not negotiated an LCP magic number: ignore (ignore the peer magic number mismatch and retain the PPP connection), or reject (router terminates the PPP connection if it detects a peer magic number mismatch)
  - keepalive-timer—Rate of LCP echo requests, in seconds
  - restart-timer—Retry frequency during LCP, IPCP, and OSINLCP negotiations, in seconds

  - magic-number—Negotiated magic number for the local and remote (peer) side of the link
  - pfc—Negotiated pfc (none or enabled) for the local and remote (peer) side of the link
  - acfc—Negotiated acfc (none or enabled) for the local and remote (peer) side of the link
    
    Note: The command displays a value of “none” for any negotiated option parameters if the option was not negotiated.
- LCP Endpoint Discriminator options:
  - local discriminator class—Endpoint discriminator type, format, and address space for the local system

show ppp interface summary

Use to display a summary of all the multilinked and nonmultilinked PPP interfaces configured on the router.
Field descriptions
- PPP Status—Non-multilinked PPP interfaces
- Configuration status—Indicates the configuration state of the PPP interface, IPCP, IPv6CP , OSINLCP, or MPLS
  - configured—Interface or protocol is configured
  - notConfigured—Interface or protocol is not configured
- Administrative status—Indicates the administrative state of the PPP interface, IPCP, IPv6CP , OSINLCP, or MPLS
  - open—Interface or protocol is administratively enabled
  - closed—Interface or protocol is administratively disabled
- Operational status (Interface)—Indicates the operational state of the PPP interface
  - up—Interface is operational
  - down—Interface is not operational because of a problem in the PPP layer
  - lowerDown—Interface is not operational because a lower layer in the protocol stack is down
  - notPresent—Interface is not operational because the hardware is unavailable
  - passive—Interface is waiting for the peer to send an LCP confReq message
  - tunnel—Interface is being redirected through a tunnel
- Operational status (Ip, Ipv6, Osi, Mpls)—Indicates the operational state of the IPCP, IPv6CP, OSINLCP, or MPLS protocol
  - up—Protocol is operational
  - down—Protocol is not operational because of a problem in the PPP layer
  - notPresent—Protocol is not operational because it does not exist
  - noResources—Protocol is not operational because it does not exist due to a lack of resources
- PPP Multilink Status—Multilinked PPP interfaces
