    Meaning

    Table 1 lists the show vpls connections command output fields.

    Table 1: show vpls connections Output Fields

    Field Name

    Field Description

    BridgeGroup

    Name of the VPLS instance for which information is displayed

    Bridge Mode

    Bridging capability currently enabled; for a VPLS instance, this field always displays default

    Aging Time

    Length of time, in seconds, that a MAC address entry can remain in the forwarding table before expiring

    Learning

    Whether acquisition of dynamically learned MAC addresses is enabled or disabled

    Max Learn

    Maximum number of dynamic MAC addresses that the VPLS instance can learn

    Link Status Snmp Traps

    Whether SNMP link status processing is enabled or disabled

    Subscriber Policy

    Name of the subscriber policy currently in effect

    Port Count

    Number of ports currently configured for the VPLS instance, including network interfaces and the VPLS virtual core interface

    Interface Count

    Number of network interfaces currently configured for the VPLS instance

    Transport Virtual Rtr

    Name of the transport virtual router configured for the VPLS instance

    Route Distinguisher

    Unique route distinguisher configured for the VPLS instance

    SiteName

    Site name configured for the VPLS instance

    Transport Virtual Rtr

    Identifier for the PE router that acts as the transport virtual router for the VPLS instance

    Multihomed priority

    Priority of the VPLS instance to serve as the backup PE router for the CE device in the event of a network failure in the multihomed configuration; indicates also that the site is multihomed

    SiteId

    Numerical site identifier configured for the VPLS instance

    SiteRange

    Maximum number of sites that can participate in the VPLS domain associated with the VPLS instance

    VPLS Route Targets

    Extended community identifiers, also known as route targets, for each VPLS instance configured on the router

    Flood Next Hop

    Index number of the MPLS next hop to which the router floods packets with unknown destination addresses. For more information about displaying MPLS next hops and any available next-hop statistics, see Monitoring MPLS Next Hops.

    Interface

    Type and specifier of the network interfaces and VPLS virtual core interface associated with the VPLS instance; vpls vplsName in this field identifies the VPLS virtual core interface

    Port

    Port number of the module on which the network interface or VPLS virtual core interface resides

    Status

    Operational status of the physical interface: Up, Down, LowerLayerDown, NotPresent

    Connections status code

    Possible status codes for the VPLS connection that appear in the State field

    Site

    Remote site identifier

    State

    Status of the connection with the remote VPLS instance; possible values for this field appear in the Connections status code legend in the command display

    Remote PE

    IP address of the remote VPLS edge (VE) router, which is analogous to the remote provider edge (PE) router in a BGP/MPLS VPN configuration

    In-label

    Incoming MPLS label from the remote site

    Out-label

    Outgoing MPLS label used to reach the remote site

    MPLS NH Idx

    MPLS next-hop index number that corresponds to the outgoing MPLS label

    Up-down Time

    Time since the last state change for this VPLS connection
