Output Fields

Table 1 lists the output fields for the show vpls connections command. Output fields are listed in the approximate order in which they appear.

Table 1: show vpls connections Output Fields

Field Name	Field Description
Instance	Name of the VPLS instance.
Local site	Name of the local site.
VPLS-id	Idenitfier for the VPLS site.
Number of local interfaces	Number of interfaces configured for the local site.
Number of local interfaces up	Number of interfaces configured for the local site that are currently up.
IRB interface present	Indicates whether or not an integrated routing and bridging (IRB) interface is present (yes or no).
Intf	List of all of the interfaces configured for the local site. The types of interfaces can include VPLS virtual loopback tunnel interfaces and label-switched interfaces. Any interface that supports VPLS could be listed here. Virtual loopback tunnel interfaces are displayed using the vt-fpc/pic/port.nnnnn format. Label-switched interfaces are displayed using the lsi.nnnnn format. In both cases, nnnnn is a dynamically generated virtual port used to transport and receive packets from other provider edge (PE) routers in the VPLS domain. Each interface might include the following information: Identification as a VPLS interface Name of the associated VPLS routing instance Local site number Remote site number VPLS neighbor address VPLS identifier
Interface flags	Flag associated with the interface. Can include the following: VC-Down—The virtual circuit associated with this interface is down.
Label-base	First label in a block of labels. A remote PE router uses this first label when sending traffic toward the advertising PE router.
Offset	Displays the VPLS Edge (VE) block offset in the Layer 2 VPN NLRI. The VE block offset is used to identify a label block from which a particular label value is selected to setup a pseduowire for a remote site. The block offset value itself indicates the starting VE ID that maps to the label base contained in the VPLS NLRI advertisement.
Size	Label block size.
Range	Label block range.
Preference	Preference value advertised for a VPLS site. When multiple PE routers are assigned the same VE ID for multihoming, you might need to specify that a particular PE router acts as the designated forwarder by configuring the site preference value. The site preference indicates the degree of preference for a particular customer site. The site preference is one of the tie-breaking criteria used in a designated forwarder election.
status-vector	Bit vector advertising the state of local PE-CE circuits to remote PE routers. A bit value of 0 indicates that the local circuit and LSP tunnel to the remote PE router are up, whereas a value of 1 indicates either one or both are down.
connection-site	Name of the connection site.
Neighbor	IP address and VPLS identifier for the VPLS neighbor.
Type	Type of connection: loc (local) or rmt (remote).
St	Status of the VPLS connection: EI—The local VPLS interface is configured with an encapsulation that is not supported. EM—The encapsulation type received on this VPLS connection from the neighbor does not match the local VPLS connection interface encapsulation type. VC-Dn—The virtual circuit is currently down. CM—The two routers do not agree on a control word, which causes a control word mismatch. CN—The virtual circuit is not provisioned properly. OR—The label associated with the virtual circuit is out of range. OL—No advertisement has been received for this virtual circuit from the neighbor. There is no outgoing label available for use by this virtual circuit. LD—The connection to the local site is signaled down, because the CE-facing interface to the local site is down. RD—The remote neighbor is down. It has signaled a problem using the pseudowire status code. LN—The local site has not been designated. RN—The remote site has not been designated. XX—The VPLS connection is down for an unknown reason. This is a programming error. MM—The MTU for the local site and the remote site do not match. BK—The router is using a backup connection. PF—Profile parse failure. RS—The remote site is in a standby state. NC—The interface encapsulation is not configured as an appropriate CCC, TCC, or VPLS encapsulation. WE—The encapsulation configured for the interface does not match the encapsulation configured for the associated connection within the VPLS routing instance. NP—The router detects that interface hardware is not present. The hardware might be offline, a PIC might not be of the desired type, or the interface might be configured in a different routing instance. ->—Only the outbound connection is up. <-—Only the inbound connection is up. Up—The VPLS connection is operational. Dn—The VPLS connection is down. CF—The router cannot find enough bandwidth to the remote router to satisfy the VPLS connection bandwidth requirement. SC—The local site identifier matches the remote site identifier. You should configure different values for the local and remote site identifiers. LM—The local site identifier is not the minimum designated, meaning it is not the lowest. The local site identifier is not being used to establish pseudowires and is also not being used to distribute VPLS label blocks. This is not an error state. Traffic continues to be forwarded to the PE router interfaces connected to the local sites when the local sites are in this state. RM—The remote site identifier is not the minimum designated, meaning it is not the lowest. The remote site identifier is not being used to establish pseudowires and is not being used to distribute VPLS label blocks. This is not an error state. Traffic continues to be forwarded to the PE router interfaces connected to the remote sites when the remote sites are in this state. IL—The incoming packets for the VPLS connection have no MPLS label. MI—The configured mesh group identifier is in use by another system in the network. ST—The router has switched to a standby connection. PB—Profile busy. SN—The VPLS neighbor is static.
Time last up	Time connection was last in the Up condition.
# Up trans	Number of transitions from Down to Up condition.
Status	Status of the (local or remote circuit) local interface: Up—Operational Dn—Down NP—Not present DS—Disabled WE—Wrong encapsulation UN—Uninitialized
Encapsulation	Type of encapsulation: VPLS.
Remote PE	Address of the remote provider edge router.
Negotiated control-word	Whether a control word has been negotiated: Yes or No.
Incoming label	Name of the incoming label.
Outgoing label	Name of the outgoing label.
Negotiated PW status TLV	Indicates whether or not the pseudowire status TLV has been negotiated for the VPLS connection.
Local interface	Provides the following information about the local interface configured for the VPLS neighbor: Name of the local interface Status—Interface status (Up or Down) Encapsulation—Interface encapsulation (for example, ETHERNET) Description—Includes the VPLS instance name, the VPLS neighbor address, and the VPLS identifier
Time	Date and time of VPLS connection event.
Event	Type of event.
Interface/Lbl/PE	Interface, label, or PE router.
Connection History	Each entry can include the date, time, year, and the connection event. Connection events include any of a variety of events related to VPLS connections, such as route changes, label updates, and interfaces going down or coming up.
