Meaning

Table 98 lists the show vpls connections command output fields.

Table 98: 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
