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.

Hi All,
I have been trying to diagnose a issue we have been having with packet loss on video calls (which I think we may have now resolved as the problem lay elsewhere), but in the process we have trailed some equipment from PathView and this seems to have created a new problem.
We have a standalone 3560G switch which connects into a providers 3750G as part of an MPLS network. There is a single uplink to the 3750 from the 3560 (@ 1Gbps) and whilst I can manage the 3560, I have no access to the providers switch. Our 3560 has a fairly vanilla config on it with no QoS enabled.
There are only a few ports used on the 3560, mainly for Cisco VCS (Video Conferencing Servers) and a PathView traffic analysis device.The VCS devices are used to funnel videoconferencing traffic across the MPLS network into another institutions network.The PathView device can be used to send traffic bursts (albeit relatively small compared with the Bandwidth that is available) across the same route as the VC traffic to an opposing device, however, I have also disabled all of these paths for the moment.
I can run multiple VC calls which utilise the VCS devices so traffic is routing into the relevant organisations and everything is good. In fact, I have 5 x 2Mb calls in progress now and there are 0 (or very, very few) errors.
However, I have actually shut-down the port (Gi0/3) connected to the PathView device for the moment. If I re-enable it I start to see a lot of errors on the VC calls, and the Total Output Drops on the UPLINK interface (Gi0/23) starts rising rapidly. As soon as I shut-down the PathView port again (Gi0/3), the error stop and all returns to normal.
I have read that issues on the Output queue are often attributed to a congested network/interface, but I don't believe that this is the case in this instance. My 5 VC calls would only come in at 10Mbps so is a way short of the 1000Mpbs available. Even the PathView device only issue burst up to 2Mbps, and with the Paths actually disabled even this shouldn't be happening, so only a small amount of management traffic should be flowing. Still, as soon as I enable the port, problems start.
So, is it possible that either the port on the switch, cable or PathView device is actually faulty and cause such errors? Has anyone seen anything like this?
Cheers
Chris"As far as I know, such drops shouldn't be caused by faulty hardware, but if the hardware is really faulty, you would need to involve TAC."
Ok, thanks.
"BTW, all the other interfaces, which have the low bandwidth rates you describe, are physically running at low bandwidth settings on the interface, e.g. 10 Mbps? If not, you can have short transient micros bursts which can cause drops. This can happen even when average bandwidth utilization is low. (NB: if these other ports average utilization is so low, if not already doing so, you could run the ports at 10 Mbps too.)"
No. All ports on the switch connect to devices with 1Gb capable interfaces. They have been left to auto negotiate and have negotiated at 1000/full. The bandwidth described is more with regard to the actual data throughput of a call. Technically, the VCS devices are licence to handle 50 simultaneous call of up to 4Mbps so potentially could require a bandwidth of 200Mbps, although it is unlikely that we will see this amount of traffic.
"Also, even if you have physically low bandwidth ingress, with a high bandwidth egress, and even if the egress's bandwidth is more than the aggregate of all the ingress, you can still have drops caused by concurrent arrivals."
In general, the ingress and the egress should be similar. Think of this as a stub network - one path in and out (via Gi0/23). The VCS act as a kind or proxy/router for video traffic, simply terminating inbound legs, and generating a next hop outbound leg. The traffic coming in to the VCS should be the same as the traffic go out.
There will of course be certain management traffic, but this will be relatively low volume, and of course the PathView traffic analyser can generate a burst of UDP packets to simulate voice traffic.
"Some other "gotchas" include, you mention you don't have QoS configured, but you're sure QoS is disabled too?"
Yes.
switch#show mls qos
QoS is disabled
QoS ip packet dscp rewrite is enabled
I can't see a lot of point enabling QoS on this particular switch. Pretty much all of the traffic passing through it will be QoS tagged at the same level. Therefore it ALL prioritised.
Indeed running a test overnight with these multiple calls live and the PathView port shutdown, resulted in 0 Total Output Drops.Each leg did suffer a handful of dropped packets end-to-end, but I think I can live with 100 packets dropped in 10 million during a 12 hour period (and this, I suspect, will be somewhere else on the network).
"Lastly, Cisco has documented, at least for the 3750X, that uplink ports have the same buffer RAM resources as 24 copper edge ports. Assuming the earlier series are similar, there might be benefit to moving your uplink, now on g0/23, to an uplink port (if your 3650G has them)."
Unfortunately, no can do. we are limited to the built in ports on the switch as we have no SFP modules installed.
Apologies about the formatting - this is yet another thing that has been broken in these new forums. I looks a lok better in the Reply window than it looks in this normal view. -

Thanks for the input. If the radio is sending out the packet but client did not receive, not output drop should be seen since packet is sent out, right?
From my understanding, output drop is related to congested interface. Outgoing interface cannot take the rate packets coming in and thus droping it. What I don't understand is input and output rate has not reached limit yet. Also input queue is seeing drop of packet as well even though input queue is empty.
Any idea? -

Cisco 2911 router interface hangs
dears,
Please note that the LAN interface (GigabitEthernet0/2) on our 2911 router is hanging. the interface stays up/up but is not reachable and stops passing traffic. the issue is temporary resolved after putting the interface in default configuration and reapplying back the configuration.
shut/no shut and router reload does not resolve the issue.

Hi,
i want to ask. My ASA5520 is generating some packet drops constantly and we have some problems with server aplication that a proccessing of tasks from client to server take a long time (sometime about 15 seconds). Our client application is accessing a server throught IPSec VPN tunnel terminated on two ASA`s. Our connectivity is about 20Mbit/s to internet and responses to ping about 5 ms and our internet load is about 20% on both sides - so i think this parameters are not bad. MTU is configured for 1500 for all interfaces. If this apllication is on local network its is working with no problems. Long responses are only throught VPN tunnel.
Can someone help me where to search for possible reasons? - is a drop rate about 2-4pkts/sec a normal behavior on Outside and Inside interface?

Hi,
Our customer took 30Mbps metro link from us. Even at 17Mbps link utilization they are facing packet drops. Our side policer is implemented for 30Mbps. There are no errors on customer or our interfaces. But I can see exceed packets under 'show policy-map interface' . Used maximum Bc. Does customer required to implement shaping his end with same CIR and Bc.
Regards
Siva KHi Siva,
It is not a mandatory rule that Customer should also have the same CIR configured with shaping.
When Customer have 30 Mbps circuit SLA with Service Provider, he may be able to pump ta line rate from CE side. But on PE side, it will be policied and excess traffic will be dropped.
To avoid Customer's traffic getting dropped at PE, It is advisible to configure shaping at CE side so that the traffic SLA will be maintained without or with less number of packet loss.
Can you post your config and show policy-map interface output with traffic?.
Regards,

I applied an access list to a VLAN interface and also added IP accounting output-packets and ip accounting access-violations. Interestingly, the devices that are allowed off the subnet can the ones that should be blocked are blocked by the ACL and show up in the show IP accounting access-v command. What I don't understand is why the show IP accounting doesn't show any packets. Also why a show access-list doesn't show any hits on the list. Is it because I'm using a VLAN interface? I would think I should see output packets and hits on the ACL. I do see dropped packets on the ACL for the violators.
Hello,
On certain platforms (hw/sw) packets are switched in hardware and not software. The RP doesn't have to make a forwarding decision. The ip accounting output-packets tracks statistics for packets via the RP. Applying a an ACL to a VLAN would typically breaks the flow of hardware switching and forces those packets to be further interrogated.
More granular traffic flows and statistics can be recorded with netflow switching. This does work on an SVI.
I hope this helps.

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
priority-queue out
mls qos trust cos
spanning-tree portfast
sh mls qos int fa0/15 st

RX Invalid nwid packets on my wifi interface
Hello,
I've got a problem with my WIFI connection using Madwifi :
When I'm under Linux, I can activate my connection with :
#ifconfig ath0 up
#iwconfig ath0 essid myAP
#iwcomfig ath0 key my:wep:64:bits:key
#dhclient ath0
And it usually works but I recieve a very large ammount of "rx invalids
nwid" packets, and so my connection is always unstable and very slow.
At the beginnin I thought that the problem was the distance between me
and the a.p. , but then I tryed to connect under windows (with the
default connection manager), and it works perfectly.
Does anyone know what could be the problem ?
Thanks a lotHello,
Here are some new informations I got ... If somebody can find what's wrong, it'd help me very much. I compare my params under windows (where the connection works very well) with the params under arch(where the connection is unstable)

Packet drops on v490 production server..help us
Hello...
We have v490 server with ce0 interface configured.. It gets down frequently & after some packet drops it makes itself up...
Can anybody tell me what could be the reason behind this problem...
I have checked switch & router by changing interface cables, still problem persists...no message on /var/adm/messages.
Thanks in advance
gmrajtry a "snoop -d ce0" and verify messages
also, perhaps the NIC is broken
also, perhaps the duplex/speed of the NIC isn't set correctly (autoneg, forced, fullduplex, halfduplex etc.) and you have to define it with a "ndd -set " -
Router Interface (7304 NSE100) QoS Input Scheduling
Guys,
I had great feedback on the Switch input scheduling question last week. Many thx to all online (and my colleagues at work) :)
If you can apply input scheduling on a switch port, ie the SP or default queues, can you apply input scheduling on a router interface?
switch
input-q----------PFC----------output-q
router
input-int---------cef-or-rp----------output-int
At the moment, most QoS for a router is done (in my expreience) on outbound scheduling, ie setting a CBWFQ bandwidth or priority and setting this policy-map outbound on the router egress interface
Should we be doing it inbound for traffic coming into a router interface before the packet gets cef switched (or sent to the RP for process or fast switching)?
So if two packets come into the router interface at the same time, based on a DSCP value, we should schedule a voice packet to be processed by CEF switching (or the RP) before an email packet?
I am just applying the switch methodology that I learned about last week to a router device. I know all routers have different archetectures, so will probably be spefific to a platform. I am using NSE100s (PXF based) on a 7304 platform.
Kindest regards,
KenJust to add i picked this from some site
GSR:
Engine 0: (Quad STM-1 POS/ATM, single STM-4 POS/ATM and others)
Engine 1: (single GEth, 8 FEth, DPT 2XSTM-4)
Engine 0 and 1 support CAR in sw; MDRR: in Engine 0 in sw
Engine 2: STM-16, Enhanced Quad OC-12/STM-4 Packet-over-SONET/SDH - 4 ports, MPLS-capable -, 8 and 16 STM-1, 3 GEth, Enhanced OC-48/STM-16 Packet-over-SONET/SDH.
no support of CAR, PIRC in hw instead; WRED in hw; MDRR in hw
(See also Quad OC-12/STM-4; Rel. Notes 12.0 S )
Engine 4: speed greater than 2.5 Gbps,
CAR, WRED, MDRR in hw
Note: no class-based shaping on GSR
But it supports DTS

Packet drops and High CPU on Cisco 3845 Switch
Hello Experts,
We are facing a lot of packet drops in our LAN.
When we try to ping one of the access switches from the CE router, we get the follwoing output:
pdel1799#ping 10.132.136.17 so 10.132.164.1 si 100 re 500
Type escape sequence to abort.
Sending 500, 100-byte ICMP Echos to 10.132.136.17, timeout is 2 seconds:
Packet sent with a source address of 10.132.164.1
Success rate is 98 percent (491/500), round-trip min/avg/max = 1/9/44 ms

I have also attached a diagram but the only router''s IP address is correct in the diagram while IP address of switches in the diagram are incorrect. Here are the correct IPs of the switches:

Access Switches:

CBWFQ: Question about the output of "show policy-map interface" command
Hi everyone,
I have a question about the output of "show policy-map interface" command.
The following is the output of this command and lower side of the output shows
(total queued/total drops/no-buffer drops) 0/342/0
If the packets drop occur due to the situation of no enough buffer,
"no-buffer drops" counted up. But "no-buffer drops" has not been counted up.
The "no-buffer drops" is 0 (zero) but "total drops" are counted as 342.
I guess there are other factors except "no-buffer drops" to add "total drops".
But I can not find any information about "other factors".
So I would like to know the "other factors" added to "total drops".

we have leased line between two sites.
one side we have 2800 series router with fastethernet port and other side we have firewall with giga
port.
Replication is done from router to firewall.
When the replication starts packet is droping when we ping to firewall outside interface.
Lease line is of 10Mbps linkWhat type of replication?
where do you see packet drop?
Do you see some sylogs?
Please provide some more information on this
