UCS : monitor interface queue drops via SNMP

[Thijs Van Severen]

Hi all,

I'm trying to find the correct SNMP OID to monitor the interface queues of my 6248UP's

It is easy enough to check the dropped packets in the queue via cli :

KOR-J11-FI4-A(nxos)# sh queuing interface eth1/29
...
Pkts discarded on ingress : 128771804
...

But i need to get this value via SNMP and i just cant find the correct OID

According to this page there is 1 MIB that handles QoS : CISCO-UNIFIED-COMPUTING-EPQOS-MIB

But i just can find anything that links to the queue drop counter ...

Any idea's ?

Greetings.

I skipped through the UCSM related MIBs, and don't think that info is exposed to SNMP.

I think that used to the be case for N7ks, but more recent code seems to have something similar to what you are looking for.  See http://snmp.cloudapps.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.9.166 and http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5500/sw/system_management/7x/b_5500_System_Mgmt_Config_7x/class_based___quality_of_service_mib.html  although this does not help your UCSM request :)

I can file an enhancement request, but frankly I just haven't seen any customer requests for it at UCSM level, which is usually what drives getting the new features/enhancements implemented.

Thanks,

Kirk...

Thanks for the feedback Kirk, i appreciate it !

I have gone tough the info you linked to and there are a couple of interesting objects like these :

CISCO-CLASS-BASED-QOS-MIB::cbQosCMDropPkt64.285212681.285212682 = Counter64: 0
CISCO-CLASS-BASED-QOS-MIB::cbQosCMDropPkt64.285212681.285212686 = Counter64: 0
CISCO-CLASS-BASED-QOS-MIB::cbQosCMDropByte64.285212681.285212682 = Counter64: 0
CISCO-CLASS-BASED-QOS-MIB::cbQosCMDropByte64.285212681.285212686 = Counter64: 0
CISCO-CLASS-BASED-QOS-MIB::cbQosCMDropBitRate.285212681.285212682 = Gauge32: 0 bits per second
CISCO-CLASS-BASED-QOS-MIB::cbQosCMDropBitRate.285212681.285212686 = Gauge32: 0 bits per second

However, none of these work :

If i do a walk on 1.3.6.1.4.1.9.9.166 i get 'object not found'

The 6248UP is based on a Nexus5k, but maybe there is a difference in SNMP capabilities ?

Unfortunately I currently dont have a N5k running so i cant verify

EDIT : just fired up a 5548UP (version 5.2(1)N1(2a)) and tried a walk on 1.3.6.1.4.1.9.9.166 > same result 'object not found'

It looks like this is a general N5k thing, not limited to UCSm

EDIT2 : did the same test on a nexus9k N9K-C9504 (NXOS: version 7.0(3)I4(5)) and here it works

Any ideas ?

I had the same response on my N5548 until I updated to 7.0(5)N1(1)

I am now getting a response and counter output at 1.3.6.1.4.1.9.9.166

I would expect to see this ported to the UCS at somepoint since it is now available in later N5K code.

Thanks,

Thanks for the update Kirk

I guess i'll just have to wait then

Do you know if there is a way that i can track this ?
