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
