Wrong value from SNMP IF-MIB::ifSpeed

Mon Jun 26, 2017 8:31 pm

Hello.

We use IF-MIB::ifSpeed in zabbix to monitor traffic of interfaces and alert when total bandwidth is above 80% for example. Well, we have one CCR 1036 with ROS 6.37.3 and running a bonding interface with 2 gigabit ports, with means one 2Gbps virtual port right? This is exactly what I get via SNMP.
Code: Select all
IF-MIB::ifDescr.17 = STRING: lagg-uplink
IF-MIB::ifSpeed.17 = Gauge32: 2000000000
But the same is not true when upgrade to ROS 6.39.1, look.
Code: Select all
IF-MIB::ifDescr.16 = STRING: lagg-uplink
IF-MIB::ifSpeed.16 = Gauge32: 1000000000
Is this information right? Or this is a BUG of version 6.39.1?

Mikrotik staff, this is clearly a bug, comments?

No, this is not fixed yet. Just tested on 6.40.3.
Code: Select all
interface bonding print                                                         
Flags: X - disabled, R - running 
 0  R name="bonding1" mtu=1500 mac-address=E4:8D:8C:1B:72:D6 arp=enabled arp-timeout=auto slaves=ether3,ether4 mode=balance-rr primary=none link-monitoring=mii 
      arp-interval=100ms arp-ip-targets="" mii-interval=100ms down-delay=0ms up-delay=0ms lacp-rate=30secs transmit-hash-policy=layer-2 min-links=0
...
Code: Select all
tool snmp-walk version=2c community=public 127.0.0.1 oid=.1.3.6.1.2.1.2.2.1.2   
OID                                                                          TYPE             VALUE
1.3.6.1.2.1.2.2.1.2.23                                                       octet-string     bonding1
...
Code: Select all
tool snmp-walk version=2c community=public 127.0.0.1 oid=.1.3.6.1.2.1.2.2.1.5
OID                                                                          TYPE             VALUE
1.3.6.1.2.1.2.2.1.5.23                                                       gauge            1000000000
As we can see, has two interfaces of 1G on this bonding, but the current speed of the bonding interface related by SNMP is 1G not 2G. This bug was initially found on versions 6.39, any plans to solve this?

This issue is generating a huge number of false positive alarms on our monitoring system.

What's new in 6.41rc38 (2017-Oct-03 11:51):
...
*) snmp - fixed "ifHighSpeed" value of VLAN, VRRP and Bonding interfaces;

Hello,

I just make a test with 6.41.3 (and 6.41 also) and the problem persists.

ifSpeed and ifHighSpeed are not informing the current speed of the Bonding interface, just of one interface on the bonding.

Please, when we can get this solved?

The fix "snmp - fixed "ifHighSpeed" value of VLAN, VRRP and Bonding interfaces;" should be backported to bugfix branch considering that many (W)ISP use this release.
One more suggestion: set ifSpeed and ifHighSpeed for pppoe client interface to tx rate limit (from profile). In this way I can check if some client is saturating the line for more than T time.
Thanks

But even on the current version, this not "fix" anything, we are getting the same wrong value.

Since 6.39 we can not use this counter properly.

It so hard to solve this bug?

We have a similar issue, .
We have two SXT units online, 1 is responding correctly to the SNMP query, the second has the Ether1 & WLAN Interfaces switched:

Both have been ungraded to 6.42.7

*** WORKING ***

IF-MIB::ifIndex.1 = INTEGER: 1
IF-MIB::ifIndex.2 = INTEGER: 2
IF-MIB::ifIndex.3 = INTEGER: 3
IF-MIB::ifDescr.1 = STRING: ether1
IF-MIB::ifDescr.2 = STRING: wlan1
IF-MIB::ifDescr.3 = STRING: SXT_Wlan

*** NOT WORKING ***

IF-MIB::ifIndex.1 = INTEGER: 1
IF-MIB::ifIndex.2 = INTEGER: 2
IF-MIB::ifIndex.3 = INTEGER: 3
IF-MIB::ifDescr.1 = STRING: wlan1
IF-MIB::ifDescr.2 = STRING: SXT_Wlan
IF-MIB::ifDescr.3 = STRING: ether1

No idea why but my reporting is all wrong.

@marcioelias

We are also using Zabbix - would you share how you do the following

IF-MIB::ifSpeed in zabbix to monitor traffic of interfaces and alert when total bandwidth is above 80% for example.

thank you

Hello @tbitech1.

For sure.

I will do better, just created a git repo to put templates, and this one is there.

https://github.com/marcioelias/Zabbix-Templates

All you will need to do is translate hardcoded titles in Portuguese.

To bypass the problem that was exposed at this thread, I have modified the trigger prototype on the Network discovery to the code below.
Code: Select all
(
    {Template Mikrotik - CCR:ifType[{#SNMPVALUE}].last(0)}=6
) and (
    (
        {Template Mikrotik - CCR:ifHighSpeed[{#SNMPVALUE}].last(0)}>0 and 
        {Template Mikrotik - CCR:ifHCInOctets[{#SNMPVALUE}].avg(300)}>{Template Mikrotik - CCR:ifHighSpeed[{#SNMPVALUE}].last(0)}*0.8
    ) or (
        {Template Mikrotik - CCR:ifHighSpeed[{#SNMPVALUE}].last(0)}>0 and (
            {Template Mikrotik - CCR:ifHCOutOctets[{#SNMPVALUE}].avg(300)}
        )>({Template Mikrotik - CCR:ifHighSpeed[{#SNMPVALUE}].last(0)})*0.8
    )
)
Basically, I'm ignoring the interface type 161 (LACP) and monitoring just ethernet-like interface types (6).

I hope that helps, plus this template will discovery all optical modules and monitoring some data.

If you have not yet done, you should send an email to support@mikrotik.com.

I have the same problem with CCR2116-12G-4S+ on ROS 7.15.2. Bonding with two SFP+, but speed in OID 1.3.6.1.2.1.31.1.1.1.15 is 10 gigabit.

I know this in an old post, but i have this issue as well, i know the value can be modified changing the custom multiplier but there must be something that can be done on the mikrotik side as well, i hope there's a solution to this
