Cisco Switching/Routing :: Output Drops In 7200 Gig Interface
Mar 13, 2012I have too much output drops in my cisco 7206 VxR NPE G1 router. I'm doing dot1Q on this interface and is connected to switch , i changed the router and IOS but still the error is same . What can be the reason . The interface on switch and router are 1000/Full and i changed the cable also . The traffic only comes about max70Mbps and it is really confusing. [code]

Jan 19, 2012we have a core switch 4507RE at the data center and 2 departments that connect to it via 10Gig fiber using X2-LRM modules. Each department has a 3 switch stack and both locations are identical w.r.t type and setup scenario.the stack comprises of 1 x 3750E and 2 x 3750G . uplink is from X2 port tengig3/0/1 from the 3750E switch.
All of a sudden dept B started facing problem , where the ping would break and throughput comes around 6 - 7 mbps from that dept to the server behind the core switch. we also noted CRC error on both sides preodically.
we replaced the multimode fiber patch cords, re did the splicing , which stopped the CRC errors to appear.now since morning the uplink port on the 3750E (3/0/1) would suddenly be in "down" state with (err-disabled) as the status when i run sh int ten 3/0/1
and i can also see CRC errors and input errors on the same interface.. if i do shut / no shut .. the port is up and active again.. but this has happned 3 times today.the core swith side is still OK and no CRC / input / output errors are seen..
now on the 3750E i have swapped the 10gig module from 3/0/1 to 3/0/2 . the port is still up but i can see 400 CRC and 500 Input errrors.the module is also OK as i had replaced it with dept 1's module.
Cisco Switching/Routing :: Giving Out Discard Error On 3750E
Apr 4, 2011We're seeing "OutDiscard" error on a LAN switch connected to newly migrated Cisco IP phones. All the other error counters are clean except for the OutDiscard. (please see attached "show int count err" output.) [URL].
According to the link above, the common cause of such discards can be to free up buffer space.(Am I seeing a switch buffer issue?) How to identify/resolve the cause of the OutDiscard.The switch is 3750-E running c3750e-universalk9-mz.122-44.SE6.bin

Apr 15, 2010I have two 3560G 24 port switches. Each of them connects to some 3560G or 2950 switches. Trunks between 3560G are set as 1000/full. Trunks between 3560G and 2950 are set as 100/full. show int status also shows the interface negotiation is 100/full for trunks between 3560G and 2950. The issue is I keep getting outdiscard errors in trunks between 3560G and 2950. At 2950 switches, I see Recv-errors too. I checked all the trunks traffic. They are totally not high. Only serveal mbps. Most time even lower than 1mbps.
I googled this kind of issue online. I see it could be possibly caused by high volume traffic higher than the capacity. But it appears the traffic there is not high enough to cause this kind of issue. Is there any possiblity that could cause this problem?

Jan 9, 2012today I witnessed a cisco n5k that stopped playing fair. For a yet unkown reason several interfaces started to show output errors all begining within the same second. While i instantly thought this would be a wiring issue I began to ask myself what an output error actually means. Google usually brings up output drops, not regular output errors. So what is it and how can a 10G fiber interface even detect that there is a problem without receiving what it was sending?

The gigabit uplinks arn't even close to fully subscribed and if I'm lucky they run at a peak of 4 - 5 Mb on a 1Gb uplink. Something really funky is going on. The individual switchports seem to have the total output drops and the uplinks at 1Gb do not have any output drops and never peak above 20Mb over a 3 month span on a 1Gb link.

Cisco Switching/Routing :: C3560 Output Drop Without MLS QoS Enabled
Nov 24, 2012We are seeing output drops on a C3560 switchport, this port does not have QoS enabled -- application does not need special qos treatment, as long as packets are not droppd, so I suppose all traffic will share the same queue? then how should I read the output of "show platform port-asic stats drop" which indicates that it is queue 3 weight 2 drop? I am wondering what is the best way to fix this? enable mls QoS and increase queue 3 bandwidth share on this interface or just increase the output queue depth?
switch#sh mls qos interface gi0/1
GigabitEthernet0/1
QoS is disabled. When QoS is enabled, following settings will be applied

Cisco Switching/Routing :: Understanding Mls Qos Queue Set Output With 3750
Apr 16, 2012I've been working on breaking down and understanding the default auto qos configuration on a Cisco 3750 in the hopes of putting together a QoS strategy that will fit our environment. I'm having some difficulty understanding how the "mls qos queue-set output" syntax works.
From another post, at [URL], the author offers the following example and explanation;
mls qos queue-set output <1/2> threshold 2 400 400 100 400thresshold 1: 400%
thresshold 2: 400%
thresshold 3: 100% (implicit, not configurable)
reserved: 100%
max: 400%
However, I'm having trouble understanding what is meant. Here, it looks like it's saying, for example;
mls qos queue-set output 1 threshold 2 400 400 100 400
How come there is syntax stating "threshold 2" when in the succeeding part the 400 refers to thresshold 1 and threshold 2 again? The syntax 400 400 is, apparently, already referring to thresshold 1 and 2, no?

(standard FiFO). As it happens the ports in question are a member of EtherChannel groups which are connected to ESX Hosts.I've also seen this behaviour also unexplained on another 3750X at a different site, however it's a single port and connects to an Upstream firewall.However in both cases neither switch has any QoS or non-standard configuration, literally a couple of VLAN's and some EtherChannel groups.Here's some output from the case involving the ESX servers.
