Monitoring Port Errors via snmp

SwOS
1

Is ist possible to monitor the error statistics per port shown in the GUI via snmp (e.g. tx pause)?

Is there a special MIB / OID trees for that?

snmpwalk -v2c -c public does not show any OIDs concerning port errors.

I also tried a dedicated snmpwalk for the following OID trees:

1.3.6.1.2.1.2 (ifTable / IF-MIB)
1.3.6.1.2.1.31 (ifXTable / IFX-MIB)
1.3.6.1.2.1.17 (bridge / BRIDGE‑MIB)
1.3.6.1.4.1.14988 (MikroTik Enterprise OIDs)

You should see tx and rx pause here in the Mikrotik MIB

$ snmpwalk -v2c -c community -m ALL -M /mibs 192.168.88.1 .1.3.6.1.4.1.14988.1.1.14.1.1.43
MIKROTIK-MIB::mtxrInterfaceStatsRxPause.1 = Counter64: 0
MIKROTIK-MIB::mtxrInterfaceStatsRxPause.2 = Counter64: 0
MIKROTIK-MIB::mtxrInterfaceStatsRxPause.3 = Counter64: 0
MIKROTIK-MIB::mtxrInterfaceStatsRxPause.4 = Counter64: 0
MIKROTIK-MIB::mtxrInterfaceStatsRxPause.5 = Counter64: 0

 $ snmpwalk -v2c -c community -m ALL -M  /mibs 192.168.88.1 .1.3.6.1.4.1.14988.1.1.14.1.1.73
 MIKROTIK-MIB::mtxrInterfaceStatsTxPause.1 = Counter64: 0
 MIKROTIK-MIB::mtxrInterfaceStatsTxPause.2 = Counter64: 0
 MIKROTIK-MIB::mtxrInterfaceStatsTxPause.3 = Counter64: 0
 MIKROTIK-MIB::mtxrInterfaceStatsTxPause.4 = Counter64: 0
 MIKROTIK-MIB::mtxrInterfaceStatsTxPause.5 = Counter64: 0

Edit: I didnt see this was posted under SWOS; I assumed RouterOS. What kind of device are you using? Im not sure what MIBs SWOS provides.

thanks, but if I try this, I get

iso.3.6.1.4.1.14988.1.1.14.1.1.73 = No Such Object available on this agent at this OID

Are they really available on switchOS or only on routerOS?

Sorry, I dont have any experience with SWOS, and you haven’t told us what kind of device you have. You can look these things up on the product site.

For instance I checked the user manual for CRS3xxx SWOS and it says

SwOS supports SNMP v1 and v2c (the Response for GetRequest, GetNextRequest and GetBulkRequest) and uses IF-MIB, SNMPv2-MIB, BRIDGE-MIB and MIKROTIK-MIB (only for health, PoE-out and SFP diagnostics

Thanks for checking the user manual.

I have a Mikrotik CSS326-24G-2S+ switch. It seems that my switch does not support error statistics via snmp, unfortunately.

Is there a way to send this as a feature requests to Mikrotik?

Im sure there is, but I dont know it. Maybe through support. Perhaps someone here knows a better answer.

Based on past experience here I would be skeptical this would be implemented soon.
