What each tested switch answers¶

	1920S	1930
Interfaces, 64-bit counters	yes	yes (physical ports and trunks)
Address table	Q-BRIDGE-MIB	Q-BRIDGE-MIB and BRIDGE-MIB
LLDP	yes, port ID is the switch MAC address	yes, port ID is the port name
Trunks	LAG-MIB; trunks are typed `other`	LAG-MIB; trunks typed `ieee8023adLag`
PoE	supplies and port status, no watts per port	no PoE
Neighbour cache	none	IPv6 in `ipNetToPhysicalTable`, IPv4 in `ipNetToMediaTable`
SNMPv3	engine present	engine present, engine ID `0000000001`

HPE 1920S sends LLDP capabilities with the two octets swapped; they are read the other way round when the first octet is empty.
HPE 1920S uses one MAC address as LLDP port ID for all ports, so the LLDP port number is taken as the ifIndex.
HPE Instant On 1930 attaches a port in no trunk to itself in dot3adAggPortAttachedAggID instead of 0.
HPE Instant On 1930: a full SNMP walk takes more than ten minutes (over 300,000 vendor entries); the library walks only the standard tables it needs (about 1.5 seconds).
