Parameters
peer ip-address: Displays information about PW labels advertised by a peer PE through LDP. The ip-address argument specifies the LSR ID of the peer PE. If you do not specify a peer PE, this command displays information about LDP PW labels advertised by all peer PEs.
pw-id pw-id: Displays FEC 128 LDP PW label information for a PW. The pw-id argument specifies the PW ID in the range of 1 to 4294967295. If you specify the peer ip-address option without the pw-id pw-id option, this command displays all LDP PW label information advertised by the specified peer PE.
vpls-id vpls-id: Displays FEC 129 LDP PW label information for a VPLS instance. The vpls-id argument specifies the VPLS instance ID, a string of 3 to 21 characters. You can specify a VPLS ID in one of the following formats:
· 16-bit AS number:32-bit user-defined number. For example, 101:3.
· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.
vsi vsi-name: Displays LDP PW label information for a VSI. The vsi-name argument specifies the VSI name, a case-sensitive string of 1 to 31 characters. If you do not specify a VSI, this command displays LDP PW label information for all VSIs.
verbose: Displays detailed information. If you do not specify this keyword, the command displays brief information.
Usage guidelines
LDP advertises FEC-to-PW label bindings in the following ways:
· After you specify a remote PE with the peer command, LDP advertises an FEC 128-to-PW label binding to the remote PE.
· After BGP discovers a remote PE, LDP advertises an FEC 129-to-PW label binding to the remote PE.
This command can display PW labels as follows:
· If you specify the pw-id pw-id option, this command displays PW labels for FEC 128.
· If you specify the vpls-id vpls-id option, this command displays PW labels for FEC 129.
· If you do not specify pw-id pw-id or vpls-id vpls-id, this command displays PW labels for both FEC 128 and FEC 129.

Predefined user roles
network-admin
Parameters
s-vid vlan-id: Matches packets with the specified outer VLAN IDs and the specified inner VLAN IDs. The vlan-id argument specifies a VLAN ID in the range of 1 to 4094.
untagged: Matches any packets that do not have a VLAN tag.
Usage guidelines
An Ethernet service instance can contain only one match criterion. To modify the match criterion, execute the undo encapsulation command to remove the criterion and then execute the encapsulation command. When you remove the match criterion in an Ethernet service instance, the mapping between the Ethernet service instance and the VSI is removed automatically.

Parameters
ip-address: Specifies the LSR ID of the peer PE.
pw-id pw-id: Specifies a PW ID for the PW, in the range of 1 to 4294967295.
in-label label-value: Specifies the incoming label of the PW in the range of 16 to 1023.
out-label label-value: Specifies the outgoing label of the PW, in the range of 16 to 1048575.
Usage guidelines
To create a static PW, you must specify the incoming and outgoing labels. To enter VSI static PW view of an existing static PW, you do not need to specify the incoming and outgoing labels.
The PW ID for a PW must be the same on the PEs at the ends of the PW.
On a PE, the LSR ID of the peer PE and the PW ID uniquely identify a PW. The peer LSR ID and PW ID combination of a PW must be unique among all VPLS PWs and cross-connect PWs.
If both the default PW ID in the default-pw-id command and a PW ID in the peer command are configured, the PW ID in the peer command is used. If only the default PW ID is configured, the default PW ID is used. If no default PW ID is configured, you must provide a PW ID in the peer command.
A static PW must have a different incoming label than an existing static LSP, static CRLSP, or static SRLSP. If they are the same, the static PW is not available, even if you change the incoming label of the static LSP, static CRLSP, or static SRLSP. To make the static PW available, delete the static PW, and reconfigure it with an unused incoming label.

Parameters
vpls-id: Specifies a VPLS ID, a string of 3 to 21 characters. You can specify a VPLS ID in one of the following formats:
· 16-bit AS number:32-bit user-defined number. For example, 101:3.
· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.
Usage guidelines
A VPLS ID uniquely identifies a VPLS instance. Two PEs must have the same VPLS ID to establish a PW.
VPLS IDs are used in the scenarios where BGP is used to find remote PEs and where FEC 129 LDP is used to establish PWs to the remote PEs.
The local PE advertises a BGP update that includes the configured VPLS ID as an extended community attribute to the remote PE. The remote PE compares the received VPLS ID with its own VPLS ID. If the two VPLS IDs are identical, the two PEs use FEC 129 LDP to establish a PW. If not, the PEs do not establish a PW.
To change a VPLS ID, execute the undo vpls-id command to remove the VPLS ID and then execute the vpls-id command.
Examples
# Configure the VPLS ID 100:1 for VSI aaa.

Predefined user roles
network-admin
Parameters
vpn-target&<1-8>: Specifies a space-separated list of a maximum of eight route targets.
A route target is a string of 3 to 21 characters in one of the following formats:
· 16-bit AS number:32-bit user-defined number. For example, 101:3.
· 32-bit IP address:16-bit user-defined number. For example, 192.168.122.15:1.
· 32-bit AS number:16-bit user-defined number, where the AS number must be equal to or greater than 65536. For example, 65536:1.
both: Uses the specified route targets as both import targets and export targets. The both keyword is used when you do not specify any of both, export-extcommunity, and import-extcommunity.
export-extcommunity: Uses the specified route targets as export targets.
import-extcommunity: Uses the specified route targets as import targets.
all: Removes all route targets.
Usage guidelines
A local PE sets the route targets as export targets in BGP update messages when it advertises L2VPN information through the update messages to a remote peer. The peer uses its import targets to match the received export targets. If a match is found, the peer accepts the L2VPN information.
