OID for "output queue drops" ?
Hi All!
We use Zenoss Enterprise to monitor our ~ 3200 Cisco devices. We have successfully been able to use OIDs such as 1.3.6.1.2.1.2.2.1.20 and 1.3.6.1.2.1.2.2.1.14 to keep an eye on ifInErrors and ifOutErrors. However, we need to monitor the transmit output queue drops, i.e. the stat reported via sh int <interface> :
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 405496
Please be gentle with me - I am NOT a SNMP guru. (I think it ought to be called CNMP - Complex Network Management Protocol ;-) . But, a starting point would be an OID that reports that value, even if it is a simple counter, we can take it from there.
Here's a screen shot of the Performance Template that is workin for montitoring other data:
Thanks!

Success! Found it here:

Thanks for being there for me, people - no really, I'm never sarcastic. Sometimes nothing does the trick like a little peer pressure combined with Mr. Google. This is a great forum with a very easy to use engine.
Here are the results from Zenoss:

Hi, i have a phone thats no working fine, it unregister all the time from the sip server.
The port connected to the phone has output queues dropped on queue 1. ¿That's normal? ¿What could be the cause that there drop packet?
Thanks!
I have this configuration for Qos on the switch port:
interface FastEthernet0/15
switchport mode access
switchport voice vlan 15

Refer to this link you need to modify your buffers etc. :http://www.cisco.com/c/en/us/support/docs/switches/catalyst-3750-series-switches/116089-technote-switches-output-drops-qos-00.html

Please rate all helpful posts -
I just recently cleared the counters on this, and I see this below. Customer states the internet is 'slow'. They have a full 100mbs connection no policy added to interface. I have increased the hold queue as you can see, but still have drops. My question is, why isnt the output queue showing any activity? It still shows 0/150 (size/max) even when its dropping. Shouldnt this number be a percentage or atleast a 150/150 when it starts dropping so you can try to figure out where a value should be?
reliability 255/255, txload 10/255, rxload 1/255
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 2828
Queueing strategy: fifo
Output queue: 0/150 (size/max)
30 second input rate 438000 bits/sec, 312 packets/sec
30 second output rate 3925000 bits/sec, 466 packets/secI am still plagued with this problem. Hopefully I will have some real answers next week with whats going on. I have a Cisco rep coming into town and should be able to work at this all week.
It appears to be strictly switch related. Going from a 1GIG interface from the core, down to 10mbs seems to be where the output drops are happening on the customers interface. I have moved a all policing/shaping onto the 1GBS core link, and still get drops. Although it is not as bad as it used to be.... I have also reconfigured the Ethernet interface to be 'auto' rather than hard coded so the customer is free to use whatever port speed they want and its rate shaped off another port.
Does anyone else have problems with this ME3400 line from Cisco? Is anyone else seeing the massive output drops?
If not, would love to see a sample config on an Internet link type of setup and a P2P setup config... -
3560 mls qos - output queues counters?
Hi!
I have WS-C3560G-24TS 15.0(2)SE4.
In gi0/10 we received IPTV multicast traffic only.
interface GigabitEthernet0/10
description IPTV
switchport access vlan 929
switchport mode access
switchport nonegotiate
mls qos trust dscp
channel-protocol lacp
channel-group 3 mode active
service-policy input iptv-cos
end
on port input - 350mbit - output 2000 Bit/s!
Queueing strategy: fifo
5 minute input rate 348797000 bits/sec, 32008 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
Then i send command:
clear counters
clear mlq qos int stat
and
sh mls qos int gi0/10 st
after 5-10 seconds i see:

Question!
Why i have 112066 packets in output queue 3, then bitrate output - 5 minute output rate 0 bits/sec, 0 packets/sec and 7 packets output, 576 bytes after clear.I have any time this bitrate.
a few hours later I see:

I haven't been able to find any documentation on CCo regarding this, but in my searching, I have come across the following MIb Object, which will tell you the input rate on the interface :
.1.3.6.1.4.1.9.2.2.1.1.6
locIfInBitsSec OBJECT-TYPE
-- FROM OLD-CISCO-INTERFACES-MIB
SYNTAX Integer
MAX-ACCESS read-only
STATUS Mandatory
DESCRIPTION "Five minute exponentially-decayed moving average of input bits per second."
There is a similar object locIfOutBitsSec (.1.3.6.1.4.1.9.2.2.1.1.8) for the output rate.
To so rxload = 255 * locIfInBitsSec / (1000000 * ifHighSpeed )
Regards

your queue limit is 20 packets. This can explain the behaviour. If there are 20 packets in the queueing system waiting to be serviced any newly arriving packet will be dropped.
Basically you can have drops in any queue in any queueing system if there is a permanent overload situation. There is no magic trick, if you f.e. permanently send 2 Mbps voip towards a T1. There will be drops.
QoS does not create resources, it just distributes them among your important traffic classes.
Besides this I also would suggest you to use class based queueing based on Modular QoS CLI (MQC). It is more flexible and precise than the old legacy methods like priority queueing, which you are using. On the other hand, if this is sufficient for you, why not.

Hi guys I am having lot of input queue drops on one of our remote router which has got an ipsec protected gre tunnel towards our main branch
Input queue: 0/75/168173/8 (size/max/drops/flushes); Total output drops: 0
Throttle count 37
Drops RP 1770332 SP 0
This is the output of an interface connecting to ISP
The other thing I would like to mention here is we have some users who connects via cisco vpn client to other sites over an already established ipsec/gre tunnel so would that be a reason of having drops?
Do I need to alter the mtu for an additional gre overhead of second tunnel
Currently tunnel interface settings are
ip mtu 1476
ip tcp adjust-mss 1380

Input queue drops can be an indication of process switching (which is unable to keep up with what's offered).
If it's just short bursts, increasing the input queue value might mitigate.
Have you reviewed Cisco's documents for troubleshooting this?
BTW, if your GRE tunnel is "protected", the MTU is likely too large as might also be your MSS adjust.
If you're just doing GRE, your MSS adjust is too small. -
We have started to install ME2600X as access switch for FTTH
Trunk ports are configured with rep and service instances
These interfaces are facing Cat 4500X switches with rep edge ports. Northbound is a 6880X VSS and this is connected to the legacy network consisting of a couple of Cat6500 + loads of Catalyst switches
We see loads of input queue drops in ME 2600X on the trunk interfaces. Even if I limit the allowed vlans out from the 4500X to the ME2600X the amount of dropped packets are still about half of the number of packets received on the interface.
Captured traffic going out of the Cat4500X towards the ME 2600X showed mostly what I suspect is REP traffic. "Show mac traffic interface" show that all packers dropped are destined for "RP".
We do not have clients on any ports yet so all traffic are inbound to the switch
I need info and help troubleshooting this. What are the criteria for drops and how do I find what is dropped on this model?Config of REP port except the service instances

Output packets drops on Router interface
Hi,
As shown in attached diagram we have connected DC and site with two ISP.
RTR1 and RTR2 are in HSRP mode and RTR2 is active router for site
We are seeing packet drops on DC RTR2 interfece connected to Sprint MPLS.
We have a site with two isp (Sprint MPLS and P2P link). Site is running on Sprint ISP.
We are seeing out put errors on DC RTR2 Sprint interface, when we failover site to P2P link from sprint.
And when fail over back to Sprint at site we are not seeing any output packets drops on DC RTR2 sprint link.

Snmp oids for the command "show counters interface intx/y delta"
Hello,
I have a question about SNMP OIDs for the command "show counters interface intx/y delta" on Catalyst6500. The customer wants to create graphs for the following values:Overruns, qos0Outlost, InErrors, OutErrors, InDiscards, OutDiscards etc..
Is possible to get these values using SNMP??
Thank you
RomanThank you, Dan. These OIDs are for the output from the command "show interface int x/y". But I think, that these OIDs are not for the command "show interface int x/y delta".

Oid for active isdn calls on cisco 3825
Hello,
we need a snmp oid for monitoring active isdn calls on a cisco 3825 running 12.4(15)T7 with VWIC2-2MFT-T1/E1 modules. OID cpmISDNCfgBChannelsInUse doesn't work, we get always 0 even if there are active calls.
Andréjclarke wrote:The CISCO-POP-MGMT-MIB has many caveats with the MAR/ISR platforms. It was designed only for the AS5xxx platforms. As a workaround for cpmISDNCfgBChannelsInUse, you can count the number of instances of isdnBearerOperStatus that return the status of active (integer 4).
Hi Joseph,
You appear to know more than most about this issue, so I will dump my query below from another string in the forums:
Please note in the output below that your suggested use of the "isdnBearerOperStatus" variable does not work in my two routers as shown. There were most definitely active channels at the time that the query was run, yet the response is always the same - status: idle (1) so I remain unable to get these stats successfully across both routers.
Any suggestions ?
I am running into exactly the same issue and have tried everything I can find to get these individual PRI (count of channels/lines in use) statistics.
Just for the record, here are some of the SNMP OIDs that I have tried (the ISRs do respond to them, only thing is, the data they send back is mostly rubbish...) the output below is from two separate routers, with different versions of IOS running (which is shown in the sysdescr response):
Note that the query in red in the second router was responded to with a valid response in the FIRST router...
All of these OIDs have been suggested at various sites online as useable SNMP OIDs for the ISR, but at other sites, they are suggested to be faulty. I have found no definitive statement for ways to get these stats successfully on the ISR platform (which amazes me.) Output below is using net-snmp to collect the stats.
I welcome any suggestions as to how this can be done reliably for the ISR, and what IOS versions WILL work. (since I am getting way different reponses to the same OIDs on the two versions below).
You'll see that for the second (DC) router below, the values are always Zero.
Yet I can guarantee that the ACTUAL stats are NEVER zero during the time period queried.
