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.
