    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 show Commands in JunosE System Basics Configuration Guide.

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

    The following tasks display information about MLPPP interfaces:

    Monitoring Baseline Statistics for MLPPP Interfaces

    Purpose

    Display baseline statistics for PPP interfaces—including MLPPP interfaces, either individual serial (member link) interfaces or multilink (bundle) interfaces.

    Action

    To display PPP interface (including MLPPP interface) statistics without baselining:

    • 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

    Table 2 lists the show ppp interface mlppp command output fields

    Table 2: show ppp interface mlppp Output Fields

    Field Name

    Field Description

    PPP interface mlppp

    Name and administrative status (up or down) for an MLPPP bundle

    PPP multilink interface

    Interface type, interface specifier, and administrative status (up or down) for an MLPPP member link

    Network interface administrative status

    Indicates whether the interface for the MLPPP bundle is administratively enabled (open), meaning that the no ppp shutdowncommand is operational, or administratively disabled (closed), meaning that the ppp shutdown command is operational

    Configured network protocol

    Network protocol configured on the interface

    Link interface administrative status

    Indicates whether the interface for the member link is administratively enabled (open), meaning that the no ppp shutdown command is operational, or administratively disabled (closed), meaning that the ppp shutdown command is operational

    Link interface fragmentation

    Indicates whether MLPPP fragmentation is enabled or disabled on the link interface

    Link interface fragmentation size

    MLPPP fragment size, in octets, currently in use on the link interface

    Link interface reassembly

    Indicates whether MLPPP reassembly is enabled or disabled on the link interface

    Link interface administrative MRRU

    Administrative MRRU value, in octets, currently in use on the link interface

    Interface statistics

    packets

    Number of packets received (in) and sent (out) on the interface

    octets

    Number of octets received (in) and sent (out) on the interface

    errors

    Number of errors received (in) and sent (out) on the interface

    discards

    Number of packets discarded on receipt (in) or discarded before they were transmitted (out)

    Note: For the LCP, IPCP, and OSINLCP negotiated options, the command displays a value of “none” if the option was not negotiated.

    IPCP protocol configuration

    configured

    IPCP is configured on this interface (true or false)

    administrative- status

    IPCP administrative status (open or closed)

    ip-address

    Address to be used for negotiation of local IP address option

    dns-precedence

    Used to resolve conflicts during DNS address negotiation

    wins-precedence

    Used to resolve conflicts during WINS address negotiation

    max-negotiations

    Maximum number of renegotiation attempts that the router accepts before terminating a PPP session

    IPCP protocol status

    operational- status

    IPCP operational status (up, down, not present, or not present no resources)

    IPCP negotiated options

    ip-address

    Negotiated IP address for the local and remote (peer) side of the link

    primary-dns-address

    Negotiated primary DNS address for the local and remote (peer) side of the link

    secondary-dns-address

    Negotiated secondary DNS address for the local and remote (peer) side of the link

    primary-wins-address

    Negotiated primary WINS address for the local and remote (peer) side of the link

    secondary-wins-address

    Negotiated secondary WINS address 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.

    OSINLCP protocol configurations

    configured

    OSINLCPis configured on this interface (true or false)

    administrative -status

    OSINLCP administrative status (open or closed)

    OSINLCP protocol status

    operational-status

    OSINLCP operational status (up, down, not present, or not present no resources)

    terminate-reason

    Reason for termination of OSINLCP service

    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
    • disabled–MRU option is not to be negotiated
    • a numeric value–MRU value to be negotiated

    authentication

    Controls negotiation of the local authentication option; value can be one of the following:

    • none–Do not negotiate
    • chap–Negotiate CHAP

    • 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
