I once did a Zabbix template for Mimosa B5c and explored several useful SNMP OID/MIB.
First we will enable SNMP in the device, check the connection from Linux and see the available OIDs:
snmpwalk -v2c -c COMMUNITY 192.168.1.2 .1
Let’s look at the list of network interfaces:
snmpwalk -v2c -c COMMUNITY 192.168.1.2 ifDescr
In my case it was displayed:
IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: tqe
IF-MIB::ifDescr.3 = STRING: eth1_emac1
IF-MIB::ifDescr.4 = STRING: wlan0
IF-MIB::ifDescr.5 = STRING: br0
IF-MIB::ifDescr.6 = STRING: br_local
IF-MIB::ifDescr.7 = STRING: br_recovery
IF-MIB::ifDescr.8 = STRING: br1
IF-MIB::ifDescr.9 = STRING: wifi0
IF-MIB::ifDescr.10 = STRING: mon.wlan0
Accordingly, to monitor traffic on the WiFi interface, I used:
ifInOctets.9
ifOutOctets.9
It is also useful to monitor the speed of the RJ-45 port, it should be 1 Gb/s (1000000000), if less, then there is probably a problem with the cable, connector, etc.:
ifSpeed.3
Here is a list of some important OIDs:

An example of viewing MAC addresses of network interfaces:
ifPhysAddress
The state of the interfaces, turned on and active, can be as follows:
ifAdminStatus
ifOperStatus
Other error counters, dropped packets, etc .:
ifInUcastPkts
ifOutUcastPkts
ifInNUcastPkts
ifOutNUcastPkts
ifInDiscards
ifOutDiscards
ifInErrors
ifOutErrors
ifInUnknownProtos
ifOutUnknownProtos
SNMP information:
SNMPv2-MIB::sysContact.0
SNMPv2-MIB::sysName.0
SNMPv2-MIB::sysLocation.0
