netdisco-do - Run any Netdisco job from the command-line.
~/bin/netdisco-do <action> [-DISQ] [-d <device> [-p <port>] [-e <extra>]]
This program allows you to run any Netdisco poller job from the command-line.
The -d option will accept a hostname (that can be resolved to an IP with DNS), an IP address, or IP prefix (subnets in CIDR format). It can be any interface on the device known to Netdisco.
-d
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.
discoverall
macwalk
arpwalk
nbtwalk
Run a discover on the device (specified with -d).
~netdisco/bin/netdisco-do discover -d 192.0.2.1
Run a discover for all known devices.
Run a macsuck on the device (specified with -d).
~netdisco/bin/netdisco-do macsuck -d 192.0.2.1
Run a macsuck for all known devices.
Run an arpnip on the device (specified with -d).
~netdisco/bin/netdisco-do arpnip -d 192.0.2.1
Run 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).
-e
-p
yes
~netdisco/bin/netdisco-do delete -d 192.0.2.1 ~netdisco/bin/netdisco-do delete -d 192.0.2.1 -e 'older than the sun' ~netdisco/bin/netdisco-do delete -d 192.0.2.1 -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.
~netdisco/bin/netdisco-do renumber -d 192.0.2.1 -e 192.0.2.254
Run an nbtstat on the node (specified with -d).
~netdisco/bin/netdisco-do nbtstat -d 192.0.2.2
Run 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.
no
~netdisco/bin/netdisco-do expirenodes -d 192.0.2.1 ~netdisco/bin/netdisco-do expirenodes -d 192.0.2.1 -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.
graphviz
mkdir ~netdisco/graph ~netdisco/bin/localenv cpanm Graph::Undirected ~netdisco/bin/localenv cpanm GraphViz
Dump the content of an SNMP MIB leaf, which is useful for diagnostics and troubleshooting. You should provide the "-e" option which is the name of the leaf (such as interfaces or uptime).
interfaces
uptime
If you wish to test with a device class other than that discovered, prefix the leaf with the class short name, for example "Layer3::C3550::interfaces" or "Layer2::HP::uptime".
Layer3::C3550::interfaces
Layer2::HP::uptime
~netdisco/bin/netdisco-do show -d 192.0.2.1 -e interfaces ~netdisco/bin/netdisco-do show -d 192.0.2.1 -e Layer2::HP::interfaces
A paramter may be passed to the SNMP::Info method in the -p parameter:
SNMP::Info
~netdisco/bin/netdisco-do show -d 192.0.2.1 -e has_layer -p 3
Start an interactive terminal with the Netdisco PostgreSQL database. If you pass an SQL statement in the -e option then it will be executed.
~netdisco/bin/netdisco-do psql ~netdisco/bin/netdisco-do psql -e 'SELECT ip, dns FROM device' ~netdisco/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.
~netdisco/bin/netdisco-do location -d 192.0.2.1 -e 'wiring closet'
Set the SNMP contact field on the device (specified with -d). Pass the contact name in the -e extra parameter.
~netdisco/bin/netdisco-do contact -d 192.0.2.1 -e 'tel: 555-2453'
Set the description on a device port. Requires the -d parameter (device), -p parameter (port), and -e parameter (description).
~netdisco/bin/netdisco-do portname -d 192.0.2.1 -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").
~netdisco/bin/netdisco-do portcontrol -d 192.0.2.1 -p FastEthernet0/1 -e up ~netdisco/bin/netdisco-do portcontrol -d 192.0.2.1 -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).
~netdisco/bin/netdisco-do vlan -d 192.0.2.1 -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").
~netdisco/bin/netdisco-do power -d 192.0.2.1 -p FastEthernet0/1 -e on ~netdisco/bin/netdisco-do power -d 192.0.2.1 -p FastEthernet0/1 -e off

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