Diagnostics¶
The package installs a command that describes what a switch answers, without any of its values:
aiosnmpswitch-diagnostics 192.0.2.10 # SNMPv2c, asks for the community
aiosnmpswitch-diagnostics 192.0.2.10 --user monitor \
--auth-protocol sha --priv-protocol des # SNMPv3, asks for the keys
Secrets are never taken from the command line; set SNMP_COMMUNITY, SNMP_AUTH_KEY and
SNMP_PRIV_KEY or type them when asked. The output names the model and firmware and counts what
each MIB returns, for example:
model: HPE OfficeConnect Switch 1920S 8G PPoE+ (65W) JL383A, PD.02.22, ...
sysObjectID: 1.3.6.1.4.1.11.2.3.7.11.186
interfaces: 13 by ifType {1: 5, 6: 8}
address table: 39 entries, with VLAN (Q-BRIDGE-MIB)
LLDP: chassis ID subtype 4, local ports 8, port ID subtypes [3], neighbours 2 on 2 mapped ports
trunks: 2 with members, LAG-MIB rows 8
PoE: 1 supplies, 4 ports
It contains no MAC or IP addresses, port names or descriptions. The model line is the
switch's sysDescr as it is: model and firmware on most switches, but some (Linux-based ones in
particular) put their host name or a serial number there. Read the output, then paste it into an
issue.
Recordings for tests¶
--record switch.raw.json writes every value the library reads into a new file that only you
can read (the name must end in .raw.json, an existing file is not overwritten). It contains
your addresses and names: never share it as it is. Maintainers turn recordings into test fixtures with
scripts/anonymize.py (see CONTRIBUTING.md).
