By default libreNMS used the ifIndex to associate ports just found via SNMP
with ports discoverd/polled before and stored in the database. On Linux boxes
this is a problem as ifIndexes are rather likely to be unstable between reboots
or (re)configuration of tunnel interfaces (think: GRE/OpenVPN/Tinc/...), bridges,
Vlan interfaces, Bonding interfaces, etc.
This patch adds a »port association mode« configuration option per device which
allows to map discovered and known ports by their ifIndex, ifName, ifDescr, or
maybe other means in the future.
The default port association mode still is ifIndex for compatibility reasons.
As port RRD files were stored by their ifIndex before, they are now identified
by their unique and stable port_id to ensure a stable and unique mapping and
allow future port association modes to be added without requireing any further
internal changes. Existing RRD files are renamend accordingly in discovery and
poller tools to ensure stability of port associations in both modules as we
don't know which might run first after an update.

DESCRIPTION
"The version number of IEEE 802.1Q that this device
supports. Reported as 1 by VLAN Bridges that support
only SST operation, and reported as 2 by VLAN Bridges
that support MST operation."
REFERENCE "12.10.1.1"
::= { ieee8021QBridgeEntry 2 }
Implements the CISCO-OTV-MIB to retrieve OTV counters from Cisco devices.
This collects information on the configured Overlays and Adjacencies
Statistics are collected for the amount of VLAN's on each overlay and the amount of MAC addresses available over each OTV endpoint.
OTV alerts are collected and generated if the appropriate alerting rules exist.
Data is displayed under routing at both the global and device level.
Includes function snmpwalk_array_num, which performs a numeric SNMPWalk and returns an array containing $count indexes
One Index:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27.18']['655360'] = 0
Two Indexes:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27']['18']['655360'] = 0
And so on...
