VOSS (Fabric Engine) VRRP Status SNMP

jeronimo — Mon, 24 Mar 2025 17:49:02 GMT

Neither Rapidcity MIB

.1.3.6.1.4.1.2272.1.73

Nor VRRP MIB

.1.3.6.1.2.1.68

seem to provide any info.

I have specified the proper snmp context (vrf).
It shows more stuff than GlobalRouter (notably routing table etc. so we know it's the correct vrf) but where is the vrrp info?

.1.3.6.1.4.1.2272.1.73.1.1.2 (rcVrrpOperTable)
or
.1.3.6.1.2.1.68.1.3 (vrrpOperTable)
would be useful.
Notably the Master/Backup state.

Thx

(FE 9.0.4)

I am going to assume that you are using VRRP v3 as 1.3.6.1.4.1.2272.1.73 does work for v2. For v3 use rcVrrpv3 (1.3.6.1.4.1.2272.1.206)

My trick to finding mibs is to take a wireshark trace of an EDM session and then look through the payload. You will find clues like this:

command=getTableVariables&userId=admin&vrfId=0&varNames=indexNA%2CrcVrrpTmpOperationsPrimaryIpAddr

Very nice, thanks.

I've never used EDM ... I thought it was used to manage a single switch. Can you connect to remote ones?
Anyway, I could've sniffed XIQ-SE's session or so, but I'd have had to revert back to unencrypted snmp etc. first...

Well, thanks.

EDM is indeed just used for single switch management. I am a CLI guy so pretty much the only time I use it is when I am trying to run down a MIB. I generally run it against a GNS3 VOSS image so I can disable HTTPS and sniff the HTTP connection.

Hi Jeronimo and TokenRingJoe.

I see the same issue, but the OID for "VRRP Operations State" remain empty.

FE: 9.0.4.0
VRF 100
VRRP-Version: 3
SNMP-View: "vrf"

# SNMP V3 MIB VIEW CONFIGURATION
snmp-server view "ALL" 1
snmp-server view "vrf" 1.3.6.1.4.1.2272.1.206

OBJECT: rcVrrpTmpOperationsState=1.3.6.1.4.1.2272.1.206.1.1.7.1.5
This object should return { initialize(1), backup(2), master(3) } but it is empty.

Does your query reply any value?

Do you have any idea whats wrong here?

Thanks in advance
Alex

I got it by myself. You need to add the context string into your query.

1. Login to the switch
2. show snmp-server context ("" = no context, vrf100, vrf200, etc)
3. Check your snmp tool where to add the context string

Now it works
