App::Netdisco::Util::SNMP
DESCRIPTION
Helper functions for SNMP::Info instances.
There are no default exports, however the :all
tag will export all subroutines.
EXPORT_OK
sortable_oid( $oid, $seglen? )
Take an OID and return a version of it which is sortable using cmp
operator. Works by zero-padding the numeric parts all to be length $seglen
, which defaults to 6.
get_communities( $device, $mode )
Takes the current device_auth
setting and pushes onto the front of the list the last known good SNMP settings used for this mode (read
or write
).
snmp_comm_reindex( $snmp, $device, $vlan )
Takes an established SNMP::Info instance and makes a fresh connection using community indexing, with the given $vlan
ID. Works for all SNMP versions.
Inherits the vtp_version
from the previous SNMP::Info instance.
Passing VLAN "0
" (zero) will reset the indexing to the basic v2 community or v3 empty context.
decode_and_munge( $method, $data )
Takes some data from SNMP::Info cache that has been Base64 encoded and frozen with Storable, decodes it and then munge to handle data format, before finally pretty render in JSON format.
