Vlan voice Packet Loss

Dear all,
strange error
configuration
2 vlan
data 10
voice 20
when I ping from the router or from a switch to the voip phone(vlan 20) I'm expereince packet lost
cisco2960x#ping 172.18.10.132 repeat 20
Type escape sequence to abort.
Sending 20, 100-byte ICMP Echos to 172.18.10.132, timeout is 2 seconds:
Success rate is 70 percent (14/20), round-trip min/avg/max = 1/3/14 ms
cisco2960x#
If a ping any other server in the vlan voice everything is working fine, this is happen with all voip phone in vlan voice
interface GigabitEthernet1/0/14
switchport access vlan 10
switchport mode access
switchport voice vlan 20
spanning-tree portfast
please advice...
Thank you

Are you trying to ping the voice servers? If yes, voice servers rate limit the icmp traffic. Try pinging from your PC, it will work fine. The reason being IOS devices transmit ping at a faster rate than the PC.

Packet loss after bonding + vlan

Hi, I am hoping someone may help me with this issue:
I have a motherboard with 2 Intel NICs.
I created a bonding interface, mode = 4 (LACP), and assigned no IP to it.
create one vlan to internet (dhcp)
another vlan to local network (static)
both NICs are connected to the same switch, and LACP configured on the ports
Problem:
ping from this one to any other pingable hosts gave strange result, more or less half of the packets are lost.
when I pulled of one cable, the ping returned to normal...
something is definitively wrong here, tried to connect the ports to two diffrent switches, same result.
other computers using LACP has no such problem in the same network.
If someone has any idea, I will be very greatful. otherwise it seems to be a very time consuming problem to solve. (I have tried to google yesterday without success).
Thanks,

I located the issue of the packet loss. I have a security system that uploads FTP images of the cameras and after the reboot of the network, the only computer that wasn't shut down was the security camera PC.
So I think what happened was after I brought everything back up, it was saturating the outgoing bandwidth, causing packet loss and high latency. Once I determined what it was and shut off the FTP image upload, the pings stabilized and it is working fine now. Trace routes are still not functioning, but I can live without that for now.

Wrong direction of Packet loss

Recently,I capture some RTP packets when user meeting the dialogue jitter and latency.
User A using the 3951 ip phone (IP address is x.x.125.206, and x.x.200.165 is the voice gateway's ip address ) , and user B using a mobile phone.
User A responds to me that she can't hear user B clearly.
This reflect to packets capture result should be packet lost at the in direction.
But the capture result show that packets loss happen at the out direction.
Could any body explain it for me?
Thanks a lot!

Probably you have captured RTP traffic near the voice gateway. Right?
I suppose that you have bidirectional packet loss.
In this case, if you use wireshark near one of the sources you can observe only one direction loss.
You must try to use wireshark in both network segments.
P.S. in the bottom of the your image we can see ip addresses of your net.
Regards.

A strange packet loss in a switching environment.

I have a switching environment with four switches as the diagram showing below. SW1 and SW2 are two Cisco 6509-E switches, SW3 and SW4 are two Cisco 4848E switches, Host 1 and Host 2 are Solaris servers.
The original issue reported was that the SSH session between two servers were not be able to established. Tcpdump result on the servers indicated there was packet loss in the network. Instead of randomly lost some of the packets, only specific packets were lost in the network.
When running ssh server on Host2 and running ssh client on Host1, the Diff-Hellman Key Exchange Reply packet from Host2 to Host1 was lost.
When running ssh server on Host1 and running ssh client on Host2, the Diff-Hellman GEX Init pakcet from Host2 to Host1 was lost.
There are no ACL configured on the switch interfaces.
The packet loss seems targeted for Diff-Hellman related packets, which is really weird. Does any one know why it happened?

I work with the individual reporting this issue and turns out a bad line card on the 6509-E where these 4948e access switches trunk to is the ultimate root cause. I don't believe there were any syslog or other indicators of the failure and it was semi-masked by the fallout being dependent on where the VLAN roots were homed so it wasn't consistent. Ultimately when the VLAN roots were reviewed in-depth, it did make complete sense on the impact being seen on just some access switches and ports and not others.
I believe I've written up all the pertinent facts here or perhaps left a few out and they will be filled in or corrected later.

Packet Loss after Reboot of ASA 5510

Hi all,
I have an ASA and a 2811 behind it and I had to replace a battery on a UPS so I had to take down the network to do it. Before doing it the network ran fine, but I did a WR MEM and a Copy RUNNING to STARTUP config thinking that the configs I had were fine. At some point in the past I must of made a change and never applied it and maybe it is causing the issue, but I am at a loss as to what is the cause. I am getting consistent packet loss from the ASA out. Any address I ping on the inside is clear and quick. Also, I do not know if it is related, but I cannot get results from TRACE ROUTES and I believe I used to.
I have confirmed the PL is related to my network, if I plug the static IP info from the provider in to a laptop, it is clear. I am at my wits end, and I know just enough to be dangerous, so any help would be appreciated.
Here are my configs:

I located the issue of the packet loss. I have a security system that uploads FTP images of the cameras and after the reboot of the network, the only computer that wasn't shut down was the security camera PC.
So I think what happened was after I brought everything back up, it was saturating the outgoing bandwidth, causing packet loss and high latency. Once I determined what it was and shut off the FTP image upload, the pings stabilized and it is working fine now. Trace routes are still not functioning, but I can live without that for now.

Ping Packet Loss across MPLS TE Tunnels

Hello...Please Help,
I have a Single Area OPSF network running across 4 main routers via GigEth Ckts. The OSPF Network is working correctly. I recently implemented MPLS TE creating two Tunnels - One Explicit Path and One Dynamic Path. Two of the Routers also have a T1 Frame Relay Link over which the Explicit path is configured. It is up and woking but I am experiencing 50-60 percent packet loss when pinging between these PE routers. When I force it to the dynamic tunnel it follows the same FR path and experiences the same packet loss. There is no packet loss anywhere else in the network.
This is a Lab environment w/three LAN's Two 7206VXR & Two 3745 routers and Three 3550 Switches - one per LAN
Suggestions?

Thank You for your response. The problem may not be an MPLS TE problem.
But would my "path-option" and "priority" being set the same for the Dynamic and Explicit Tunnels cause one tunnel to come up and the other go down and cease to signal. Right now I have one or the other working when viewed w/the "show mpls traffic-eng tunnels" command. If I take one down the other works.
The IPs are 10.1.101.1 & 2/30 respectively for the FR Link. That was a Typo...I have corrected it.
The FR interfaces are not SubInt's as the Serial Interface holds the IP address. These are strictly Point to Point but I have the "IP OSPF Network Broadcast" command set and OSPF going across them.
I have SubInt's set on the Gi0/3 Interface.
Gi0/3.1 & 3.10 for VLAN's 1 & 10
There are not any drops when pinging from Within the routers "Interface to Interface".
But when I ping the LAN Node to Node or from within the Router "if" I do not specify an "interface source" I receive the drops.
The result is the same from either side of the Network on both of the 7206 Routers.
Thanks, Kevin

3750ME packet loss

Hello,
We have several 3750MEs with the latest IOS 12.2(40)SE. We experience some annoying packet loss (around 1% or less) on any FastEthernet port no meter of its mode (we have almost all standard scenarios - trunk with sever vlans just passing the switch, access ports providing L3 vlan routing) when the traffic on a particular vlan on the port exceeds 20 Mbit/s.
We have checked and rechecked all cabling, configured all ports and machines connected to the switch manually to speed 100, duplex full, switchport nonegotiate etc.
However there is no problem when we do the same with any of the Gig ports (both normal and ES).
Switch resource monitors are as low as unplugged switch (cpu is under 10%, all tcam resources are below 10% too).
I've looked around the forum but didn't find any problem with great similarity to our.
So basically I'm totally out of ideas. Any help will be blessed.
P.S. For the record if I replace the 3750 with simple managed vlan switch (like HP ProCurve) there is no problem - I say this to eliminate questions about cabling and misconfiguration on attached ethernet intefaces.

I've started this conversation in the Network Infrastructure forum, so please if anyone have any ideas about this issue please write there to keep it on one place.
Thanks.

ME 3400 PACKET LOSS

e3400 packet loss
I have a me3400 connected as follows:
in port G1 / 0 fiber optic switch connects 7 WS-C2960-24TC-s.
The switches are running vlans 2960 and serves to intervlan ME3400 routing.
All of the GTW vlans are defined in the ME3400, in addition this does dhcp for network VLANs.
In the port f0 / 1 is defined as non-me3400 swichport and create an interconnection network with a firewall that outputs the internet
in ports f0 / 5 f0 / 6 is set up a vlan me3400 additional servers
problem:
When a machine that is in the vlans, located in any switch in 2960, seeking access to the servers connected to the f0 / 5 f0 / 6 has lost and slowly, the same is true if you want to access the internet.
Tests done from a PC on the vlans.
If it pings with size 100 to the servers or the firewall is not a problem.
but if you increase the size of the datagram to 500 or 1000 are lost. \
If ping with size of 1000 from a PC to me3400 no problem.
From me3400 If you ping the router or 100 servers with no loss size, but if it increases to 500 or more lost packets again has all of the above results that both the internet as accceso to this rather slow servers . It is worth mentioning that the vlan voip telephony and servcio not a problem.
Assistant to the configuration of me3400

Security and packet loss problem

Guys,
I'm using WRTP54G-NA and I have 2 problems with it...
First one: is about security, if I access direclty http://192.168.0.1/admin/voice or any other subfolder it doesn't ask me the password...
The other problem is that I can't let my connetion 100%, It always has packet loss, in both way, wired and wireless (more in wireless), I had already tried to fix the Negotiation to 100Mbps Full duplex, changed the MTU values for different values and there is always packet loss...
I tried to plug my pc directly to the cable modem and it works perfectly...
I'm using firmware version 3.1.24, I also tried with 3.1.27, but with 3.1.27 the number of problem increases including now ones...
Any advice ??

I don't think that the rotuer will ask you for username & pasword once you login to setup page ... Only once it will show you the same when you are typing http://192.168.0.1 on the browser address bar ...

Troubleshooting packet loss

From which ouput of the command can I know the packet loss of VoIP is occuring?

The coutners in show interface have included the packets loss of all the data including voice, so I want to find out how I can find the packet loss for voice only. It seems the show active voice command should have these parameters, but I don't know exactly which output of this command is indicating the packet loss of voice.

Packet loss unacceptable?

I have a test setup of a cisco 2106 wlc and a 1231ag access point in lightweight mode. ive been having issues with dropped connectivity trying a lot of different wpa2 setups. i've finally peared it down to a pretty plain config of a wpa2 psk non-broadcast ssid with most of the options turned off under advanced in the wlan config. i have a linux laptop and a windows laptop testing, both located about 10ft from the ap with perfect signal strength.
i can connect fine, and i do a steady ping from the laptops to another (wired ip) for testing. i'll let it go, and then look at the ping statistics. i always have a couple of pings lost. it's usually 0% because its like 3 pings out of 800. but is this acceptable? i thought wifi was supposed to be collision avoidance. is there an easy way to debug this besides putting wireshark inbetween the AP and the WLC, then the WLC and the core switch, etc...

I consider 3 pings lost out of 800 to be entirely normal/acceptable behavior in 802.11. If you look at our design guidelines for VoWLAN (voice being pretty much the "canary in the coal mine"), you will see that we specify no more than 1% packet loss for a voice call, so 0.4% would be considered well under that threshold.
An unlicensed wireless channel is nothing like a Cat5E point to point cable. It's a half duplex channel with very high BER - many many orders of magnitude worse than 1000BASE-T, typically with all kinds of 802.11 and non-802.11 interferers encroaching. To be sure, the 802.11 CSMA/CD works hard to avoid collisions and to keep retransmitting to get its packets through at layer 2 - but when radar or a microwave oven starts stepping all over the physical layer, no upper layer magic is going to get the bits through.
If you don't like 0.4% packet loss and want to troubleshoot it ... then you would typically need something like wireless packet capture on your channel, plus spectrum analysis (like Spectrum Expert) to catch any non-802.11 interference. Maybe you will find that there are 5GHz channels available that are cleaner than the 2.4GHz that you're trying to use now. (Assuming that you are using 2.4GHz, you don't say.)

High Packet Loss on Media Gateway and Mediation Server leg

Hello,
We have recently begun to receive SCOM alerts showing a high percentage of poor voice quality on calls that are being sent to voicemail. QoE Reports show an extremely high packet loss on the Media Gateway and Mediation Server leg of the call.
The SCOM alerts are similar to this:
Alert: Media quality alert for gateway and Mediation Server leg
Source: Microsoft.LS.2010.QoE.Metric.AudioQuality.GatewayMS
Path: MonServer01;10.1.1.1 - FESERVER01;10.1.1.1 - FESERVER01 Last modified by: System Last modified time: 9/13/2013 9:16:17 AM Alert description:
Following are the details for this media quality alert:
Media quality alert for: Gateway and Mediation Server leg "10.1.1.1 - FESERVER01"
Total calls = 51
Poor quality calls = 12
Poor quality call percentage (%) = 23.53
Following are the average values for call classification metrics:
Average network degradation = 0.08
Average jitter (ms) = 1.86
Average packet loss (%) = 3.71
Average round trip time (ms) = 0.00
Average concealed metric (%) = 16.33
Average stretched metric (%) = 0.57
Average compressed metric (%) = 0.92
These alerts did not seem to be popping up until we enabled Media Bypass and CAC. The call setup looks like this:
MEDIANT 3000 -> MEDIATION SERVER -> UM SERVER
We have had our networking team take a look at all legs of the network between subnets and they do not find any dropped packets.
Any ideas what might be causing this to happen ONLY on calls that are transferred to voicemail?
Thanks.

Please try to disable Media Bypass and CAC to check if still have the issue.
Try to enable Media Bypass and CAC one at a time to check which cause the packet loss.
Tyr to use Lync Logging Tool to collect trace file on Lync Mediation Server.

Hi Lisa,
I Turned off CAC and left Media Bypass on. I received 87% packet loss, although when listening to the voicemail, I heard no drops at all. Here are the stats:
Audio Stream (Caller -> Callee)

Then I turned on CAC and turned off Media Bypass. Left a message. 0% Packet Loss. Voicemail sounded perfect once again. Here are the stats:

    Audio FEC: False Bandwidth estimates: 0 Kbps

    Avg. network MOS degradation: 0.15 Max. network MOS degradation: 0.18
    NMOS degradation (jitter): 0.00 % NMOS degradation (packet loss): 0.00 %
The kicker is, with media bybass enabled, the call going to Voicemail (Exchange UM) is not a media bypass call. The Lync Mediation server is handling the call in both instances (Media Bypass ON or OFF).
I'm thinking it's a problem with the reporting feature since no visible/physical packet loss can be seen or heard. Our issue also lies with the fact that it's throwing of our call quality stats for the day because of the amount of "poor calls" going
to voicemail.
I would really love to figure this out. Any thoughts?

I've just spent a fustrating 15 minutes with Bt Support chat who just seemed want to pass me on to the BT Business team, so I thought I'd post here, for a more informed response.

Hi Jane, Thanks for the reply. I have now purchased an AEBS(n) to try to overcome this problem. The Apple site says it is compatible with all versions of Airport card so I thought it would solve the problem. My new problem is to be found here: http://discussions.apple.com/thread.jspa?threadID=1087292&tstart=0
However to answer your questions, The OS is 10.4.10 and I have run every updater I can find for all Macs concerned. hope this helps.

These are the results of a test I ran, but I don't know how to solve the problem. The game is unplayable because of the amount of packet loss. I know it is an issue of connection between the game and my router, so should I get a new router if mine is old?

The router I would imagine to be okay for the first bit, but for the sake of things, reboot the router and also try giving your ONT a reboot by unplugging it from AC power and then disconnecting the battery. Re-connect it after 30 seconds by connecting the battery and then plugging it back into AC power.
Also, see if the packet loss takes place during specific times of the day. If your router has a WAN connection over Coax (rather than an Ethernet connection) to your ONT, also consider checking your MoCa speeds based on this FAQ. Poor MoCa speeds can suggest shoddy coaxial causing some issues, too: https://secure.dslreports.com/faq/verizonfios/3.2_MOCA#16569

WIFI Packet Loss/Jitter MacBook Air 11 & LION OSX 10.7.1

I started using computers more than 30 years ago when I was 5, I had my first IBM PC at the age of 10 and have never had any interest in paying over the odds for an Apple mac mainly because I saw the Mac as a kind of "Can't open nothing", one mouse buttoned retard of the computer world.
That is, until now.
I set up an online business 3 years ago and rented a dedicated server and set the whole business up in a cloud, so to speak. Having done that, all I needed a laptop for was a remote desktop connection and to run a SIP phone (Internet phone).
My PC based laptops had almost nothing installed on them, and I wasn't using software on the laptop itself, I was using remote desktop, so - why not try a MAC? The new Macbook Air 11 is small, light and made of metal and glass so should be robust enough to travel with me.
I have to say, this was the worst move I've ever made.
I opened the new shiny macbook and the first thing I noticed was that the internet seemed hit and miss. Moving around the room I managed to find a spot whereby pages woud load quickly. Strange, my £200 acer laptop was sh.t fast everywhere in the house. No matter, I packed it back away and carried on working on the Windows machine.
I've come to Newquay this week, and i've started to try and use the Macbook again in a hotel. The wireless signal in the room is low, and speedtest shows about 1 meg down and 3/4 meg up. That may sound bad to you, but remote desktop uses about 5k/sec (modem dial up speed) and the softphone, well, my Asterisk VOIP setup is confugured to use the GSM codec so that's 8k/sec each way + overheads.
This whole setup was deliberately designed to be "thin" so I can travel with ease and work on bad connections like USB internet sticks.
Anyhow, the Macbook was unable to hold a stable connection to the remote desktop or SIP phone, even though the speed test showed a whopping 1 meg up and down. What you may not be aware of is that there is more to a connection than the speed, there is the quality as well. How many packets are lost / how much "jitter" is on the line.
Anyhow, we're not living in the 3rd world, I ran a PINGTEST and it showed a small amount of jitter but told me the line was class B, online games may suffer but voip should be fine.
I unpacked the Acer, placed it in exactly the same spot as the Apple had sat in and it worked beautifully with 1 bar of wireless signal, all day long. Phone calls were clear.
So you know now what I'm thinking. I'm sitting here with my £200 acer because I can't use the £1500 macbook air 11. I paid nearly sixteen hundred pounds for this piece of .... and it doesn't ...... work. Time to contact Apple support.
2nd Mistake!
Representitive 1: - Told me that I can't compare the Macbook Air to the Acer, the Acer has Google Chrome and everybody knows Google Chrome is the fastest browser. I was told there was nothing more he could do, its probably a bad line at the hotel. When I explained the Acer works fine for voip I was told well, maybe it is getting a better signal. I explained the Acer has the cheapest possible parts inside it and paid 1500 for this macbook, expecting it to have quality parts inside and was told I'd paid for the size, because its so small but its not considered "powerful". Apple do you train your staff? Clearly not.
Thank god I wasn't paying to talk to this moron.
Representitive 2: - Had no idea what packet loss or Jitter was, got me to do a speedtest and said that looks fine. Then he got me to remove the WIFI adapter and re add it in the network settings.
Guess what, nothing changed, its still the same hardware and software.
Representitive 3: - Still not really understanding "quality" issues with the networking interface, I was asked to install the latest Java client. I did it, only because I wanted to comply with Apples wishes so they'd help me, but they weren't helping and Java has nothing to do with the network adapter, so that was useless advice too.
Apple seem to have no idea there is a problem, even though Google has pages and pages of people saying the same as me, and their own discussion forums have thousands of people complaining https://discussions.apple.com/thread/2664670?start=0&tstart=0
Finally, late yesterday whilst speaking to d.ck head number 3 at Apple support, we found a forum post talking about a fix, 10.7.1 update. I told d. head number 3 about the update and he suggested I applied it. So I did and everything looked great, for a whole evening.
This morning, I switched on again and the same thing, slow remote desktop, choppy unusable phone. Remember the phone needs less than 20k for a conversation, thats 0.2 meg. Speedtest again showing a whole meg both ways.
I called apple support again, this time being a little forceful, and I've asked for this to be escalated, but the bottom line is - they have no fix, they don't aknowledge this as a problem and I was told LION is new, so maybe it's got a bug..
I told the guy on the phone this is a network driver issue, the intermittency of the problem shows that and the Apple's lack of settings for the network adapter means the unit is autonegotiating with the router and choosing speed and duplex settings on its own. Sometimes it does that correctly, other times not and the connection although fast has a lot of noise / packet loss / corruption.
I've found a workaround, you put the unit to sleep and wake it up again and it runs fast until the next shutdown. Not really acceptable seeing as I was paying for "the cream of the crop".
I will definately not be recommending Apple products, and i'll certainly not be replacing the Windows laptops in my business with Apple's toytown system- i'd go out of business if I had to rely on this.
All there is left now, is to look at Boot camp and see if I can wipe this waste of space linux hack from the unit and install Windows 7.

I unpacked the Acer, placed it in exactly the same spot as the Apple had sat in and it worked beautifully with 1 bar of wireless signal, all day long. Phone calls were clear.
So you know now what I'm thinking. I'm sitting here with my £200 acer because I can't use the £1500 macbook air 11. I paid nearly sixteen hundred pounds for this piece of .... and it doesn't ...... work. Time to contact Apple support.
2nd Mistake!
Representitive 1: - Told me that I can't compare the Macbook Air to the Acer, the Acer has Google Chrome and everybody knows Google Chrome is the fastest browser. I was told there was nothing more he could do, its probably a bad line at the hotel. When I explained the Acer works fine for voip I was told well, maybe it is getting a better signal. I explained the Acer has the cheapest possible parts inside it and paid 1500 for this macbook, expecting it to have quality parts inside and was told I'd paid for the size, because its so small but its not considered "powerful". Apple do you train your staff? Clearly not.
Thank god I wasn't paying to talk to this moron.
Representitive 2: - Had no idea what packet loss or Jitter was, got me to do a speedtest and said that looks fine. Then he got me to remove the WIFI adapter and re add it in the network settings.
Guess what, nothing changed, its still the same hardware and software.
Representitive 3: - Still not really understanding "quality" issues with the networking interface, I was asked to install the latest Java client. I did it, only because I wanted to comply with Apples wishes so they'd help me, but they weren't helping and Java has nothing to do with the network adapter, so that was useless advice too.
Apple seem to have no idea there is a problem, even though Google has pages and pages of people saying the same as me, and their own discussion forums have thousands of people complaining https://discussions.apple.com/thread/2664670?start=0&tstart=0
Finally, late yesterday whilst speaking to d.ck head number 3 at Apple support, we found a forum post talking about a fix, 10.7.1 update. I told d. head number 3 about the update and he suggested I applied it. So I did and everything looked great, for a whole evening.
This morning, I switched on again and the same thing, slow remote desktop, choppy unusable phone. Remember the phone needs less than 20k for a conversation, thats 0.2 meg. Speedtest again showing a whole meg both ways.
I called apple support again, this time being a little forceful, and I've asked for this to be escalated, but the bottom line is - they have no fix, they don't aknowledge this as a problem and I was told LION is new, so maybe it's got a bug..
I told the guy on the phone this is a network driver issue, the intermittency of the problem shows that and the Apple's lack of settings for the network adapter means the unit is autonegotiating with the router and choosing speed and duplex settings on its own. Sometimes it does that correctly, other times not and the connection although fast has a lot of noise / packet loss / corruption.
I've found a workaround, you put the unit to sleep and wake it up again and it runs fast until the next shutdown. Not really acceptable seeing as I was paying for "the cream of the crop".
I will definately not be recommending Apple products, and i'll certainly not be replacing the Windows laptops in my business with Apple's toytown system- i'd go out of business if I had to rely on this.
All there is left now, is to look at Boot camp and see if I can wipe this waste of space linux hack from the unit and install Windows 7.
