NAME
App::Netdisco::Util::Device
DESCRIPTION
A set of helper subroutines to support parts of the Netdisco application.
There are no default exports, however the :all
tag will export all subroutines.
EXPORT_OK
get_device( $ip )
Given an IP address, returns a DBIx::Class::Row object for the Device in the Netdisco database. The IP can be for any interface on the device.
If for any reason $ip
is already a DBIx::Class
Device object, then it is simply returned.
If the device or interface IP is not known to Netdisco a new Device object is created for the IP, and returned. This object is in-memory only and not yet stored to the database.
delete_device( $ip, $archive? )
Given an IP address, deletes the device from Netdisco, including all related data such as logs and nodes. If the $archive
parameter is true, then nodes will be maintained in an archive state.
Returns true if the transaction completes, else returns false.
renumber_device( $current_ip, $new_ip )
Will update all records in Netdisco referring to the device with $current_ip
to use $new_ip
instead, followed by renumbering the device itself.
Returns true if the transaction completes, else returns false.
match_to_setting( $type, $setting_name )
Given a $type
(which may be any text value), returns true if any of the list of regular expressions in $setting_name
is matched, otherwise returns false.
is_discoverable( $ip, [$device_type, \@device_capabilities]? )
Given an IP address, returns true
if Netdisco on this host is permitted by the local configuration to discover the device.
The configuration items discover_no
and discover_only
are checked against the given IP.
If $device_type
is also given, then discover_no_type
will be checked. Also respects discover_phones
and discover_waps
if either are set to false.
Also checks if the device is a pseudo device and no offline cache exists.
Returns false if the host is not permitted to discover the target device.
is_discoverable_now( $ip, $device_type? )
Same as is_discoverable
, but also compares the last_discover
field of the device
to the discover_min_age
configuration.
Returns false if the host is not permitted to discover the target device.
is_arpnipable( $ip )
Given an IP address, returns true
if Netdisco on this host is permitted by the local configuration to arpnip the device.
The configuration items arpnip_no
and arpnip_only
are checked against the given IP.
Also checks if the device reports layer 3 capability, or matches force_arpnip
or ignore_layers
.
Returns false if the host is not permitted to arpnip the target device.
is_arpnipable_now( $ip )
Same as is_arpnipable
, but also compares the last_arpnip
field of the device
to the arpnip_min_age
configuration.
Returns false if the host is not permitted to arpnip the target device.
is_macsuckable( $ip )
Given an IP address, returns true
if Netdisco on this host is permitted by the local configuration to macsuck the device.
The configuration items macsuck_no
and macsuck_only
are checked against the given IP.
Also checks if the device reports layer 2 capability, or matches force_macsuck
or ignore_layers
.
Returns false if the host is not permitted to macsuck the target device.
is_macsuckable_now( $ip )
Same as is_macsuckable
, but also compares the last_macsuck
field of the device
to the macsuck_min_age
configuration.
Returns false if the host is not permitted to macsuck the target device.
get_denied_actions( $device )
Checks configured ACLs for the device on this backend and returns list of actions which are denied.
