You can launch all TrafficDirector executable files and utilities directly from the command line. This chapter lists each executable file and utility, along with a short description. To list the arguments for an executable file or utility, enter its name at the command prompt, followed by a space, and press Enter. TrafficDirector lists the arguments, if any.
Command-line utilities are an alternative way to launch applications, graphs, daemons, and other utilities from outside the TrafficDirector Graphical User Interface (GUI). Most of the command-line utilities in this chapter have a direct counterpart you can use in the GUI. The functionality is the same, whether you launch from the GUI or from a command-line utility.
Keep in mind that each utility has separate arguments that you can use. For more information about exact syntax and arguments to use with a command-line utility, See the on-line man pages.
Command line utilities are useful in many different situations. Table 51-1 lists all command-line utilities in alphabetical order and describes each one.
This table lists all command line utilities in alphabetical order, describes the type of each utility, and directs you to the page where you will find the description. After the table, you will find a brief description of each utility, categorized by function, starting on page 49-4.

Noninteractive utilities are tools that you can use "behind the scenes" of the TrafficDirector GUI to administer database tables, event logs, and perform several advanced functions that do not have a GUI. The following noninteractive utilities are available:
| dvadmin | Maintains the trap destination "admin" table that the specified agent uses to determine which hosts that receive Simple Network Management Protocol (SNMP) trap as the result of a Trap Manager event. Also use dvadmin to add or delete entries or list the contents of this table. |
| dvattach | .Attaches a port or slot as a monitor port for a switch you specify. |
| dvcl | Lists all or some of the contents of the conversation table for the agent and domain you specify. |
| dvclean | Deletes some or all of the Management Information Base (MIB) tables from the agent you specify. You can specify certain types of tables to delete, or not specify any table type to delete all tables (this is the same as a soft reset on the agent). |
| dvdcap | .In the agent, captures packets associated with a given filter, stops data capture, uploads captured packets from the agent to a file, and deletes data capture in an agent. You can also use this utility as part of a shell script that is executed when a Trap Manager-defined alert is received. |
| dvdeins | tDeinstalls some or all MIB tables associated with a specific domain from the agent specified. You can specify certain types of domain tables to delete, or not specify any table type to delete all domain tables. If you deinstall a domain on an Remote Monitoring 2 (RMON2) probe, it frees agent resources without deleting the domain however, if you deinstall a domain on an RMON probe, the domain is deleted. |
| dvdetach | .Detaches a port or slot as a monitor port for the specified switch you. |
| dvdomid | Gets the agent channel number (instance) associated with a specific domain and writes the result to stdout (if the result is 0, the specified domainis not installed). Use this utility to launch non-TrafficDirector applications that might require the instance of tables associated with a specific domain. |
| dvdump | Dumps agent information or agent MIB tables. Use this utility to troubleshoot by looking at the details of the raw agent MIB tables or by looking at agent information, including IP address, IFN, IFTYPE, and MAC address. If you use this utility to dump agent MIB table information, you can specify to dump certain types of MIB tables or all MIB table types. |
| dvevlog | Dumps internal agent event logs associated with a specific domain (event logs usually correspond to alarms the agent sends when a threshold set in Trap Manager is reached or exceeded). |
| dvftp | .Downloads DLCI configuration information into a specified agent. |
| dvfdstn | Manages and monitors the ring station list of Fiber Distributed Daya Interface (FDDI) agent. Use this utility when you need to create or delete a ring station table that a specific FDDI agent maintains. You can also use this utility to list the status for all stations on the ring or get configuration information for an individual station. |
| dvge | tGets and displays the value of a specified SNMP variable. |
| dvhelp | Provides help with the syntax and arguments for any dv command. |
| dvhist | Lists contents of the agent history table for a specified domain. Use this utility to get the segment statistics history that the agent maintains for a specified domain. You can get either long- or short-term history. For Token Ring agents, you can get either the default promiscuous or non-promiscuous, MAC-level history. |
| dvhl | Lists some or all of the contents of the host table for the specified agent and domain. |
| dvinst | Installs domains at a specified agent. This utility can be used instead of the interactive Domain Manager application on TrafficDirector main window. |
| dvlearn | .Autodiscovers complex devices on a network segment, such as ports on a switch and Frame Relay agent DLCI ports. The results of this command line utility may automatically create files, such as the x.swp files (for learned switch ports) and x.frp files (for learned Frame Relay DLCI ports). |
| dvlist | Lists the domains installed at an agent, including the host mode that the domain uses for host and conversation tables, and the yes/no flags that indicate which tables are installed that are associated with the domain. If you redirect the displayed output when you use the dvlist utility to a file, you can use it as the configuration file for the dvinst utility. |
| dvnex | tGets and displays the next SNMP variable defined in the MIB table after the one you specify with the dvnext utility. |
| dvreport | Generates reports noninteractively. Use this utility at the command line or from a script to generate tabular and CSV reports noninteractively. |
| dvset | Sets the value of an SNMP variable you specify to an OID type (-i for integer, -s for string, -h for MAC address, and -o for object identifier) and a corresponding value. Use this utility to change the type and value of an SNMP variable. |
| dvsnap | Provides a snapshot of domain activity for a short-term period. Use this utility to display segment, host, or conversation statistics for a specified interval. |
| dvtime | Converts time intervals to timestamps suitable for use with the dvreport utility. Use this utility to help generate daily, weekly, or monthly reports noninteractively. You can pass the output of dvtime as start time and end time timestamp command-line arguments to the dvreport utility. |
| dvtrsr | Manages and monitors the source routing table aToken Ring agent. Use this utility to create or delete the source routing table maintained by a Token Ring agent. You can also use this utility to list the contents of the table. |
| dvwalk | Gets and displays all SNMP variables defined in an MIB table, starting from a variable you specify. |
