* CH: patch H3C broken node-vlan mapping
see https://github.com/netdisco/snmp-info/issues/218
--+ qb_fw_vlan
qb_fw_vlan is called to figure out in which vlan a mac is located.
fetch qb_fw_port. This is a hash
fdb_id.mac => fdb_port
for each key split of fdb_id
try to look it up in qb_fdb_ids to translate it to vlan
otherwise use it directly as vlan.
--+ qb_fw_port
qb_fw_port fetchs snmp dot1qTpFdbPort, oid 1.3.6.1.2.1.17.7.1.2.2.1.2
This snmp table returns
fdb_id.mac => fdb_port
as an example data fetched from a HP switch (Layer2::HP)
SNMPv2-SMI::mib-2.17.7.1.2.2.1.2.3.52.20.95.80.231.59 = INTEGER: 9
fdb_id: 3
mac: 34:14:5f:50:e7:3b
fdb_port: 9
and an expample for a H3C (Layer3::H3C)
SNMPv2-SMI::mib-2.17.7.1.2.2.1.2.1.0.17.17.117.83.217 = INTEGER: 891
fdb_id: 1
mac: 0:11:11:75:53:d9
fdb_port: 891
snmp looks got. Verified with netdisco
/opt/netdisco/bin/netdisco-do show -d <SWITCH> -e Layer3::H3C::qb_fw_port
/opt/netdisco/bin/netdisco-do show -d <SWITCH> -e Layer2::HP::qb_fw_port
result looks good.
--+ qb_fdb_index
qb_fdb_index fetches snmp dot1qVlanFdbId which is oid 1.3.6.1.2.1.17.7.1.4.2.1.3
This snmp table returns
timestamp.vlan => fdb_id
netdisco will strip the timestamp and build a hash
fdb_id => vlan
for a HP switch i get snmp data
SNMPv2-SMI::mib-2.17.7.1.4.2.1.3.0.64 = Gauge32: 6
vlan: 64
fdb_id: 6
for a H3C i get
SNMPv2-SMI::mib-2.17.7.1.4.2.1.3.3330.64 = Gauge32: 1
vlan: 64
fdb_id: 1
and there are the issues.
not all vlans are listed
every line has fdb_id 1
as in all H3C switches i checked, the fdb_id is equal to the vlan i patched out
qb_fdb_index to return an empty hash.
* CH: H3C fix pod caverage test
Co-authored-by: Christoph Handel <c.handel@gsi.de>
* ident
* remove $Id$ tags from rcs software which has been retired
* make an effort to sync required mib docs with actual code
* sync even more docs with what code actually does
* some whitespace nits
* fixup example to use snmpv2 for all but the most ancient devices
* remove blurb to find more specific snmp::info classes for classes
which alrdy are as specific as they can get (eg snmp::info::layer3::vmware
doesn't need info on to find a specific module since there ain't none)
* rename all sub {vendor} strings to lowercase vendor, if cisco, juniper
and arista can be lowercase, so can be all the rest.
* fix tests
* spread some use warnings around
* use $ instead of @
* remove defines that are included via parent classes
* use strict + warnings
* remove alrdy included modules
* add comma after last list item
* typos
* mibs are found in our mib repo, not on the cisco site
* documentation fixes
