netdisco-do - Run any Netdisco job from the command-line.


 ~/bin/netdisco-do <action> [-DISQR] [--enqueue] [--force] [--quiet] [-d <device> [-p <port>] [-e <extra>]]


This program allows you to run any Netdisco poller job from the command-line.


Note that some jobs (discoverall, macwalk, arpwalk, nbtwalk) simply add entries to the Netdisco job queue for other jobs, so won't seem to do much when you trigger them. Everything else happens in real-time.

However the "--enqueue" option will force the queueing of the job, regardless of type. This may be useful for cron-driven actions, or for actions working across large IP spaces. Netdisco will refuse to queue more than 512 jobs at once unless you also add the "--force" option.

For any action, if you wish to run one of its individual worker stages, then pass action::stage as the first argument to netdisco-do, for example discover::neighbors.

Any action taking a device parameter can be passed either a hostname or IP address of any interface of a known or unknown device, or an IP prefix (subnet) which will cause netdisco-do to run the action on all addresses in that range.

The device parameter may be passed multiple times. In this case, all addresses (after expanding IP Prefixes) will be handled one by one.


Run a discover on the device (specified with -d).

 ~/bin/netdisco-do discover -d

Run a discover on two different devices (specified with -d).

 ~/bin/netdisco-do discover -d -d


Queue a discover for all known devices.


Run a macsuck on the device (specified with -d).

 ~/bin/netdisco-do macsuck -d

Submit macsuck results directly to Netdisco by putting the JSON data in a file and using the -p option (see API web docs for data format example):

 ~/bin/netdisco-do macsuck -d -p /tmp/mac-address-table.json


Queue a macsuck for all known devices.


Run an arpnip on the device (specified with -d).

 ~/bin/netdisco-do arpnip -d

Submit arpnip results directly to Netdisco by putting the JSON data in a file and using the -p option (see API web docs for data format example):

 ~/bin/netdisco-do arpnip -d -p /tmp/arp-table.json


Queue an arpnip for all known devices.


Delete a device (specified with -d). Pass a log message for the action in the -e parameter. Optionally request for associated nodes to be archived (rather than deleted) by setting the -p parameter to "yes" (mnemonic: preserve).

 ~/bin/netdisco-do delete -d
 ~/bin/netdisco-do delete -d -e 'older than the sun'
 ~/bin/netdisco-do delete -d -e 'older than the sun' -p yes


Change the canonical IP address of a device (specified with -d). Pass the new IP address in the -e parameter. All related records such as topology, log and node information will also be updated to refer to the new device.

Note that no check is made as to whether the new IP is reachable for future polling.

 ~/bin/netdisco-do renumber -d -e


Run an nbtstat on the node (specified with -d).

 ~/bin/netdisco-do nbtstat -d


Queue an nbtstat for all known nodes.


Run Device and Node expiry actions according to configuration.


Archive nodes on the specified device. If you want to delete nodes, set the -e parameter to "no" (mnemonic: expire). If you want to perform the action on a specific port, set the -p parameter.

 ~/bin/netdisco-do expirenodes -d
 ~/bin/netdisco-do expirenodes -d -p FastEthernet0/1 -e no


Generate GraphViz graphs for the largest cluster of devices.

You'll need to install the Graph::Undirected and GraphViz Perl modules, and possibly also the graphviz utility for your operating system. Also create a directory for the output files.

 mkdir ~/graph
 ~/bin/localenv cpanm Graph::Undirected
 ~/bin/localenv cpanm GraphViz


Dump the content of an SNMP MIB Object or an SNMP::Info method, useful for diagnostics and troubleshooting.

You should provide the "-e" option which is the name of the method or object, such as interfaces or uptime or ifDescr.

If you wish to specify the SNMP MIB to load and find the Object in, then you can qualify the "-e" parameter, such as IF-MIB::ifDescr.

If you wish to test with a specific SNMP::Info device class other than the one discovered, pass this in the "-p" parameter, such as Layer3 or SNMP::Info::Layer3 (the SNMP::Info prefix is optional).

All "-e" parameters are case sensitive.

 ~/bin/netdisco-do show -d -e interfaces
 ~/bin/netdisco-do show -d -e IF-MIB::ifDescr
 ~/bin/netdisco-do show -d -e interfaces -p SNMP::Info::Layer2::HP
 ~/bin/netdisco-do show -d -e ifName -p Layer3::Arista

The "-e" parameter specify will show the used configuration for the specified device.

 ~/bin/netdisco-do show -d -e specify

This command works well with the "-I" debug flag on SNMP::Info (or "-II").


Start an interactive terminal with the Netdisco PostgreSQL database. If you pass an SQL statement in the -e option then it will be executed.

 ~/bin/netdisco-do psql
 ~/bin/netdisco-do psql -e 'SELECT ip, dns FROM device'
 ~/bin/netdisco-do psql -e 'COPY (SELECT ip, dns FROM device) TO STDOUT WITH CSV HEADER'


Updates Netdisco's statistics on number of devices, nodes, etc, for today.


Set the SNMP location field on the device (specified with -d). Pass the location string in the -e extra parameter.

 ~/bin/netdisco-do location -d -e 'wiring closet'


Set the SNMP contact field on the device (specified with -d). Pass the contact name in the -e extra parameter.

 ~/bin/netdisco-do contact -d -e 'tel: 555-2453'


Set the description on a device port. Requires the -d parameter (device), -p parameter (port), and -e parameter (description).

 ~/bin/netdisco-do portname -d -p FastEthernet0/1 -e 'Web Server'


Set the up/down status on a device port. Requires the -d parameter (device), -p parameter (port), and -e parameter ("up" or "down").

 ~/bin/netdisco-do portcontrol -d -p FastEthernet0/1 -e up
 ~/bin/netdisco-do portcontrol -d -p FastEthernet0/1 -e down


Set the native VLAN on a device port. Requires the -d parameter (device), -p parameter (port), and -e parameter (VLAN number).

 ~/bin/netdisco-do vlan -d -p FastEthernet0/1 -e 102


Set the PoE on/off status on a device port. Requires the -d parameter (device), -p parameter (port), and -e parameter ("on" or "off").

 ~/bin/netdisco-do power -d -p FastEthernet0/1 -e on
 ~/bin/netdisco-do power -d -p FastEthernet0/1 -e off


Generates rancid configuration for known devices. See App::Netdisco::Worker::Plugin::MakeRancidConf for configuration needs.

 ~/bin/netdisco-do makerancidconf


Generates an API key for the supplied username. See the API doc for further information.

 ~/bin/netdisco-do getapikey -e the_username 


Will dump the loaded and parsed configuration for the application. Pass a specific configuration setting name to the -e parameter to dump only that.

Some configuration items like device_auth are evaluated against the ACL first. Pass a device in -d to display them:

 ~/bin/netdisco-do dumpconfig -d -e device_auth


A requirement for web browsing of SNMP data (see snapshot command), run this to load Netdisco MIBs into the database. It only needs to be done once.


Builds and saves a data structure which Netdisco can use to mimic the device (if shared) and also browse the SNMP Objects in the web.

By default the command will gather Objects for web browsing. Use the -p parameter (mnemonic: persist) to save the cache at "logs/snapshots/IP" in NETDISCO_HOME (where IP is the canonical IP of the device). You can share the file and it can be used to create a realistic pseudo device in another installation.

 ~/bin/netdisco-do snapshot -d -p file

Optionally use the -e parameter to request MIB Objects other than the defaults. This parameter takes a comma-separated list and supports three types of item: MIB names (the file name in netdisco-mibs), MIB vendor (in netdisco-mibs, will load all the MIBs within), or SNMP::Info class (loads all MIBs needed).

 ~/bin/nedisco-do snapshot -d -e SNMP::Info::Layer3::Arista
 ~/bin/nedisco-do snapshot -d -e PICA-PRIVATE-MIB
 ~/bin/nedisco-do snapshot -d -e cisco,net-snmp
 ~/bin/nedisco-do snapshot -d -e SNMP::Info::Layer3,PICA-PRIVATE-MIB,net-snmp

Note that to web browse the gathered SNMP data, you also first need to run the loadmibs command.


Adds a Pseudo Device which can be used to connect together unconnected parts of your network or to gather ARP via CLI/API when SNMP is not available.

Pass the Pseudo Device IP in the -d parameter. Pass the Pseudo Device name in the -e parameter. Pass the number of ports (one or more) in the -p parameter. All parameters are required. For example:

 ~/bin/netdisco-do addpseudodevice -d -e fakerouter -p 10


The flag "-R" will cause any changes to the database to be rolled back at the end of the action.

The flags "-DISQ" can be specified, multiple times, and enable the following items in order:


Netdisco debug log level.

-I or -II

SNMP::Info trace level (1 or 2).

-S or -SS or -SSS

SNMP (net-snmp) trace level (1, 2 or 3).


DBIx::Class trace enabled.

In case of issues with the colored output, setting the environment variable ANSI_COLORS_DISABLED can be used to suppress it.
