DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide traceroute mpls ipv4 NETWORK-PREFIX/PREFIX-LENGTH [timeout SECONDS] Parameters NETWORKPREFIX/PREFIX-LENGTH timeout SECONDS Specifies the IPv4 prefix FEC whose LSP connectivity will be checked. Specifies the interval in seconds to send the MPLS request packet. This value must be between 1 and 99 seconds. The default value is 2 seconds. Default None. Command Mode User/Privileged EXEC Mode. Command Default Level Level: 1. Usage Guideline This command is used for hop-by-hop fault localization as well as path tracing the LSP of the specified FEC. If there is no LSP for the specified FEC, the 'Destination unreachable' message will be displayed. Otherwise, MPLS echo request messages will be sent out to the LSP of the specified FEC. The TTL in the outmost label of the MPLS echo requests is set successively to increasing numbers, so that it forces the echo request to expire at each successive LSR along the LSP. The LSR returns an MPLS echo reply. If the sender does not receive a reply before the timeout, the traceroute will stop. Example This example shows how to trace route the LSP for network 192.1.1.0/24. Switch# traceroute mpls ipv4 192.1.1.0/24 Reply from 170.1.1.1, time
