(see sprotoRip).

6.1.14 Traceroute
An implementation of traceroute was added in order to add the ability to orginate a traceroute request from the ELS10-26. The request can be started from LCM, or from SNMP. If the request is originated from the LCM, the results are printed out on the LCM console.
The LCM command is as follows: traceroute [-m max_ttl] [-q nqueries] [-w wait] host_IP
[data_size]
The traceroute MIB has a variable which indicates the amount of time the results of a traceroute request is accessible from SNMP. It also has a table, indexed by NMS IP address, ping destination IP address, hop count, and probe count which is used to start the traceroute request and fetch the results. Each entry in the table will contain the round trip time and state of each particular probe in each hop.
