trace mpls vpls
Sends MPLS echo request packets with successively higher TTL values to the specified VPLS instance. Discovers the path MPLS packets follow to the destination. There is no no version.

- vrfName—Name of the VRF context
- vplsName—Name of a VPLS instance created with the bridge vpls transport-virtual-router command
- senderSiteId—Numerical identifier for the site sending the MPLS echo request packet; must be an unsigned 16-bit integer greater than zero that is unique across the VPLS domain
- remoteSiteId—Numerical identifier for the site receiving the MPLS echo request packet; must be an unsigned 16-bit integer greater than zero that is unique across the VPLS domain
- startIpAddress—First IP address within the 127.0.0.0/8 destination range
- endIpAddress—Last IP address within the 127.0.0.0/8 destination range
- increment—Number in the range 0–255 that specifies the increment between addresses in the destination address range
- sourceAddr—IP address used as the packet source address
- ttlValue—Hop count specified by setting the time-to-live field in the header, in the range 1–255; default value is 32
- timeOutVal—Number of seconds in the range 1–32 to wait for an MPLS echo reply packet before the connection attempt times out
- reply mode—Specifies the reply mode for the echo request packet
- ipv4-udp—Specifies that the echo request packet is an IPv4 UDP packet
- ipv4-udp-with-router-alert—Specifies that the echo request packet is an IPv4 UDP packet with the router alert bit set in the header so all routers examine this packet more closely to determine whether further processing is necessary
- reply pad-tlv—Requests sender of an echo reply to send a pad TLV
- trafficClass—Number in the range 0–255 that represents the value of the traffic class that the sender of an echo reply is requested to set
- bitValue—Value of the EXP bits in the range 0–7 included in the MPLS echo request packet
- bottomLabelTtl—Time-to-live value of the bottom label in the stack
- detail—Displays detailed information about MPLS echo request sent and echo replies received
