El Capitan Dropping packets

• Drop Packet BOUNCING

  Whenever ESXi is powered on, a switch of gigabyte or a FastEthernet switch... I have drop packet. Take a look at the picture so see what I mean.

  Here's the scenario:

  Cable Modem - > 2821 Gi0/0 - > 3550 Gi0/0 - Port-Channel 1

  -Gi0/2 and Gi0/3-> ESXi Server (with IP hash)

  -> host: DNS/DHCP Win2008 Vlan 40

  -> VMkernel: 10.10.80.5

  Before being on a purchase order, the ESXi server was plugged into a regular trunk port.

  If I use a laptop computer plugged into a port on the switch... I get an IP address and the DNS works well.

  HERE'S THE PROBLEM:

  

  I have NO IDEA why she did this. The iOS are more recent. The server is updated to the latest version. WinServ2008/DNS/DHCP uses a network card VMnet3 and not E1000.

  ESXi is 5.5.

  I did the configuration of VMware with this tutorial:

  VMware KB: Example configuration of EtherChannel / control protocol LACP (Link Aggregation) with ESXi/ESX and Cisco/H...

  ANOTHER FACT: when the port Gi0/2 and Gi 0/3 are closed, no more problems.

  The router config and Switch is below.

  Can someone help me?

  PROBLEM SOLVED!

  I can't find the article, but he was right. In this article, they said that the decline of the package could be the cause of the Vkernel interface in the same vswitch as virtual machines.

  So I vmnic1, configured as a switchport access vlan 80.

  Then, I changed the ip address of the interface vlan 255.255.255.252 80 to 10.10.80.6.

  (my vcenter server is already set up to the communication of the esxi via 10.10.80.5).

  

  Here is the final result that now works. MORE NO PACKET DROP.

  Thank you all!

• ASR9K | drop packets when ping provider of next hop.

  Hello guys,.

  I have an ASR9k and one of its interface connected to BT supplier multiple subinterface and corresponding VRF is configured on this 10G link.

  The question is: when I ping the next hop (BT ip address) with meter 1000 and the 1500 mtu size, I get a success to drop and 98% patterns. This decline of 2% packet affects traffic voice on it.

  My MTU configured as 8900 and mtu configured as 9058 BT and as it is not more traffic so I don't think that the configured Qos policy is applied on the movement.

  UserEnd to ping server is fine but still I'm down 2% on a point to clicking on supplier link, can you please give some idea about this to solve?

  Hello

  I think that what is expected. Since it is a drop of water to grounds, this indicates that there is traffic is limited in rate or some sort of CoPP in game.

  In IOS XR, LPT plays this role. Maybe it's rate limiting of traffic from the ping packets are destined to the CPU.

  Please refer to the below document Xander:

  https://supportforums.Cisco.com/document/93456/asr9000xr-local-packet-tr...

  Hope that clarifies

• S2S vpn pings go but watch drop packet tracer

  Hi guys,.

  Thanks for a great forum!

  I have a vpn tunnel of work implemented between 2 ASAs, that I use the tunnel daily for management purposes. When I simulate the traffic entering the tunnel at tracers package one end shows a drop of water...

  The flow rate is gcoutside inside the shared_vpn_inside interface.

  Packet-trace entry tcp gcoutside 192.168.77.109 10000 192.168.70.10 80 retail

  It gives the following:

  Phase: 8

  Type: VPN

  Subtype: ipsec-tunnel-flow

  Result: DECLINE

  Config:

  Additional information:

  Direct flow from returns search rule:

  ID = 0x744b44f0, priority = 69 = ipsec-tunnel-flow area, deny = false

  hits = 32062, user_data = 0xb2f965c, cs_id = 0 x 0, reverse, flags = 0 x 0 = 0 protocol

  Hide ip src/id =192.168.77.0, = 255.255.255.0, port = 0, = 0 tag

  IP/ID=192.168.70.0 DST, mask is 255.255.255.0, port = 0, tag = dscp 0 = 0 x 0

  input_ifc = gcoutside, output_ifc = any

  And just to point out, all through the tunnel works... I can't find any errors anywhere... Not in the newspapers, nowhere.

  Why is it when everything seems to work?

  See you soon

  Hello

  I guess I could have remembered as bad. I tend not to use the "packet-tracer" to test the management VPN remote connections to the Local level. I tend to use to begin the negotiation of VPN when I don't have access to equipment that can use the VPN L2L connection.

  So it would be nice if you can not just simply test connectivity to the subject of connection that are supposed to be coming through a VPN connection. Even if this VPN connection is currently on the rise.

  I actually tested with earlier with a couple of different units of the SAA, and it has not worked for the connection which were rising and negotiated SAs.

• Equium M40X - slow internet packets dropped

  I use a wi - fi connection and my pc keeps dropping packets from time to time (and also not connected via LAN) making my internet connection is a bit slow.
  I had my wifi router has changed and he always does.

  Reflection on the upgrade of BIOS and wireless driver here but it of too risky, time-consuming and can it not cure all cases.
  My gut feeling is some process is suddenly from time to time and slow things down (my mouse movements sometimes freeze for a few seconds).

  I have AVG Anti-Virus installed, you run scan and no viruses found.
  I've defragged and run the registry cleaner.

  Any ideas I can try to find out what is the cause. see you soon

  Hello

  I put t know if it s really a problem!
  I very often use WiFi and I noticed a similar issue.
  But it really depends on the site and server I connect.

  However, the WLan driver update should be done initially to check if this could sort the WiFi issue but to be honest I m not sure if it is a WLan problem, due to the fact that this also occurs when you use the local network.

  I think you should check if a Windows updates are possible and available.
  If the new versionis available BIOS, check if the BIOS update helps.
  The use of a firewall might have a bad influence on the transmission too!

• Increase the packets received per second UDP

  I have a very high packages (over 100,000 packets per second) rate which I'm trying to capture in LabView.  I configured a single loop to form the loop 'UDP receive' that takes the data from the wire and updates these data in a queue to be processed by another loop.

  The problem is that if I use the builtin UDP receive functions, or one library implementations available OCAP, I will always drop packets.  When the receive loop running I have the time I find it runs only in the range of milliseconds rather than the necessary<10us.  if="" i="" remove="" the="" 'enqueue'="" call,="" and="" do="" nothing="" except="" receive="" the="" data="" and="" increment="" a="" packet="" counter,="" it="" is="" still="" no="" where="" near="" meeting="" timing. ="" this="" leads="" me="" to="" believe="" that="" the="" problem="" is="" with="" the="" amount="" of="" time="" it="" takes="" to="" call="" the="" vi="" to="" perform="" the="">

  Until I write a dll to perform multiple readings of package and transfer the pads of large size to labview, is there something that can be done in labview to increase the rate of packets?  Note that I have captured these data in wireshark on the same computer, and it's more the enough to capture all the data, so it is possible.

  Attached are two examples that do not work because the loop execution rate is too low.  Exactly why the loop runs too slowly is a mystery to me.  Note the "OCAP" version uses the library from the mentioned thread previously.

  The problem is now resolved.  I've updated the dll from this thread to include a "multi-package-group" function that provides in bulk packages to labview.  Even after doing this, I noticed that there was always a bottleneck when LabView went to assemble the packets (data collection of several packages to more large data sets).  This was solved by moving some of the manipulation of specific project data in the dll as well.  When I have free time, I also plan on accounting for the new library in this same thread of OCAP.

• Drop ID vs Reset

  I understand that drop a package prevents the connection broke in your network, and a TCP Reset resets the connection in both directions.

  Which is not functionally pretty much the same thing? Whatever it is, you end the connection, right?

  Since TCP Reset only works on TCP traffic, why even use it? Is not abandoning the connection good enough take care of this?

  A question to be considered is that of system resources.

  If the ear falls the connection (or packets), the connection is not able to continue.

  BUT the client and the server think that the connection is still ongoing and will return packets and conserve system resources open until a possible time-out occurs.

  With TCP Reset, another part of the client and the server knows the connection has been reset and may release the system resources and stop making resends.

  However, the TCP Reset by itself, does not guarantee that the connection will disappear.

  TCP Reset is a better estimate for the sequence of numbers for the connection to be reset. You are indeed to misuse of the connection, and diversion does not always work (especially in fast connections).

  If all you are worried for prevents an attack then drop packets works very well.

  But if you are worried about dropping the attacks but also to free up system resources (particularly a web server that can be constantly attacked in the case of worms) I would recommend that you use the action down and restore actions.

  SIDE NOTE:

  Version 4.1 of the ID software support TCP resets, but does not support the actions of moving.

  SPI version 5.0 (forthcoming) will support a new InLine feature that supports drop as actions (the so-called deny actions in IPS v5.0). So in 5.0, you can do the two rejections of an action and a tcp reset action on signatures which often fire. This way your servers won't be wasting resources on connections that have already been removed by the PPE.

• Cisco IDS 4.1 probes in HA? monitor package drops?

  Hello

  can someone tell me if Cisco IDS sensors provide high availability or failover capabilities? If so, how and where to fix?

  Is there a form any notification drop package when sensor starts a fall of packages under full load?

  Hello

  IDS sensors do not provide high availability or failover capability.

  Under a high load of the sensor can be configured to alert of hamid question the 993 which States "package dropout rate exceeded the threshold. This threshold is set by default to 5% (Total dropped packets / Total packets received in a time interval). You must enable this GIS as it is disabled by default.

  Ping statistics for 172.16.17.1:

  Packets: Sent = 4, received = 0, lost = 4 (100% loss),

  I also see that attached to the devices in the DMZ are taken excessively long time.

  The MTU size on all interfaces is always the default value of 1500.

  Hi Jimmysturn:

  Which is likely happened here is that you have ID political attack linked to your external interface with the action 'drop' or 'reset' all packages that match the signature in the category of the attack.

  Signature 2151 (large ICMP) will drop packets hit the PIX off interface or those who pass through the PIX outside interface when you ping with large packet size (+ 993 bytes):

  From your post, you must have had the following policy of IDS on your PIX:

  IP audit name attackpolicy attack action fall

  (or

  IP audit name attackpolicy action fall attack alarm

  or

  attack IP audit name attackpolicy raz action alarm

  or both)

  If you want to ping with big package, there are several things you can do:

  (1) remove the policy of "attackpolicy" completely from your external interface. It will turn off all of the IDS signatures in the category of the attack.

  Carefully look at this and see if it's what you want to do.

  To achieve the above, issue the following command:

  "no interface verification ip outside of attackpolicy"

  (2) turn off the signature 2151 by running the command:

  "disable signature verification ip 2151.

  That would disable only the big signing of ICMP attack while leaving the other signatures of attacks in the category of GIS attack ON.

  (3) set signature action to open a session (a syslog server or the internal buffer) large ICMP packets instead of dropping. Again, this should be determined carefully as option 1.

  To achieve the above goal, issue the following command:

  IP audit alarm action name attackpolicy attack

  It will be useful.

  Please indicate the position accordingly if you find it useful.

  Sincerely,

  Binh

• How to get the statistics of all the virtual machines that is going down the network packet last week?

  Hello

  I have this script (new) to Mr. LucD grace who 'supposed' to collect the list of any package of network statistics dropped as scheduled:$start = Get-Date ' 01/01/2015 00:00 " "»

  $finish = Get-Date "21/01/2015 14:30"
  
  $metrics = "net.droppedRx.summation","net.droppedTx.summation"
  foreach($esx in (Get-VMHost)){
      $vms = Get-VM -Location $esx
      if($vms){
          Get-Stat -Entity $vms -Stat $metrics -Start $start -Finish $finish -ErrorAction SilentlyContinue |
          where {$_.Instance -ne ""} |
          Group-Object -Property {$_.Entity.Name,$_.Instance} | %{
              $_.Group | Group-Object -Property Timestamp | %{
                  New-Object PSObject -Property @{
                      VMHost = $esx.Name
                      VM = $_.Group[0].Entity.Name
                      VmNic = $_.Group[0].Instance
                      "Receive Dropped Packets" = $_.Group | where {$_.MetricId -eq "net.droppedRx.summation"} | Select -ExpandProperty Value
                      "Transmit Dropped Packets" = $_.Group | where {$_.MetricId -eq "net.droppedTx.summation"} | Select -ExpandProperty Value
                      Timestamp = $_.Group[0].Timestamp
                      "Interval (seconds)" = $_.Group[0].IntervalSecs
                  }
              }
          }
      }
  } | Export-CSV -path C:\Temp\Result.CSV
  

  but somehow there is no results coming out of this script?

  How can I get the result the. CSV file?

  The ForEach loop do not put anything in the pipeline, but that can be fixed by using the call operator (and)

  $finish = get-Date ' 21/01/2015 14:30 '.

  $metrics = "net.droppedRx.summation", "net.droppedTx.summation".

  & {foreach ($esx in (Get-VMHost)) {}

  $vms = get-VM-location $esx

  {if ($VMS)}

  Get-Stat - $vms - Stat $metrics entity - start $start - finishing $finish - ErrorAction SilentlyContinue |

  where {$_.} {Example - don't ""} |

  Group-object - property {$_.} @entity.name, $_. Instance} | %{

  $_. Group | Group-object - property Timestamp | %{

  New-object PSObject-property @ {}

  VMHost = $esx. Name

  VM = $_. Group [0]. @entity.name

  VmNic = $_. Group [0]. Instance

  "Receive ignored packages" = $_. Group | where {$_.} MetricId - eq "net.droppedRx.summation"} | Select value - ExpandProperty

  "Transmit ignored packages" = $_. Group | where {$_.} MetricId - eq "net.droppedTx.summation"} | Select value - ExpandProperty

  Timestamp = $_. Group [0]. Timestamp

  'Interval (seconds)' = $_. Group [0]. IntervalSecs

  }

• Internet comments works the machine randomly

  I have a problem with the internet connection in my VMWare guest computer works very randomly (for the most part does not work) and I'm not sure of what could be the issue.

  Sometimes the internet works (this also includes option to ssh to the host), but most of the time it doesn't.

  "Networking" restarting does not help, nor any how 'ifdown' /'ifup "s. The only situation when he could start work is restart the entire virtual machine. And even then it starts to work maybe once in 10.

  The single issue so far, I've noticed is that when it does not, the MAC addresses of the NICs VM are swapped - so if it works, they are configured.

  Details:

  Here I see the only difference - MAC addresses are on the other hand, compared to their configuration.

  When the internet works:

  -of the prompt, ping 192.168.195. * all works very well (. 200,.2-1)

  -the host, I ping (. 1) and guest (. 200),.2 ping gives me the error of"request timed out".

  When it does not work:

  -from the prompt I can ping myself (192.168.195.200), but ping any other * 192.168.195 (.2 ou.1) gives me the error «Host unreachable home» Even when the rattling of the internet (for example 8.8.4.4)

  -from the host, I can ping myself (192.168.195.1), but ping any other * 192.168.195 (.2 ou.200) gives me the error of"request timed out".

  No idea why this could happen, and what else I could try?

  Thank you!

  Hi maciejzz

  Welcome to the Fusion community

  It seems that your network card is not properly configured.

  ethernet0.startConnected = 'TRUE '.

  ethernet0.VNET = "vmnet2.

  ethernet0.bsdName = 'en0 '.

  ethernet0. DisplayName = "Wireless connection"

  This section shows your VM should be in the bridged network. But,

  ethernet0. Present = 'TRUE '.

  ethernet0. ConnectionType = "nat".

  ethernet0.wakeOnPcktRcv = "FALSE".

  ethernet0. AddressType = 'static '.

  ethernet0.linkStatePropagation.enable = "FALSE".

  ethernet0.pciSlotNumber = "33".

  ethernet0. Address = "00:50:56:38:CC:21".

  It shows that you are in NAT network.

  If you please remove your "ethernet0"? First of all you should turn off your virtual machine, and then the VM settings-> network-> advanced card-> remove the network card, and then add a new by VM-> Add Device settings-> network? If you want your virtual machine to use '00:50:56:38:CC:21' as MAC address, you can set it up the network-> Advanced Network card, then enter the MAC to textfield. When this process is complete, turn on your virtual machine and see if your problem is resolved.

• Yoga 900 - battery plugged in, does not support.

  Hello

  I seem to have a 'No load' intermittent problem on my Lenovo Yoga 900.

  This happens often when it is fully charged and I unplug for a few minutes and then plug it in again. If I let it go below 93 to 95% it will tell usually "plugged in, charging" again.

  Is this some kind of glitch or a feature? I tried looking to see if I had the setting of 'conservation' and I do not have.

  I have a few days to take it back to the store if I need to. I'd really rather not send it because we have problems of the Stagecoach drop packets that end up getting robbed because we live in an apartment with several locked doors, so they usually it plant next to the door and run off and then someone else takes off with our business. Had it happens a few times with orders from Amazon. (grr)

  Thanks to anyone who can answer this question!

  Comment to Moderator: The model is added to the object for clarity.

  Good day and welcome to the community.

  It is my experience with my 900 Yoga and the Yoga s 900. In this way the system does not constantly on 1 or 2%, which is not good for the battery. In contrast, Mode of Conservation will be charge at ~ 60% and then stops. That has certain advantages, too. Personally, I don't use The Mode of preservation, and so far I have not seen no negative effect on my batteries.

  I hope this helps.
  Kind regards.

• Routing to the unauthorized via switch Ethernet HP 1910 169.254.0.0/16 subnet

  Hello

  I have a somewhat unusual situation at a customer site. They have an HP 1910 as a default gateway on their local network Ethernet switch. This is related to a Fortigate Firewall with a regular DSL connection and a WAN link to emote subnets. The question we have is that a new remote site has become active on the Wan. The unusual thing is that they have a 169.254.0.0/16 subnet. Don't ask me why this address range has been used but it is there. (169.254.0.0/16 is a space of address reserved for windows clients that cannot receive an IP via DHCP)

  The client is when they try and access a resource on 169.254.0.0/16 through the switch and on the Wan of the HP 1910 switch removes the packages and will not pass them. I have trioed add static routes on the switch, but it does not transmit packets 169.254.0.0/16. Al, the other traffic is very well. Has anyone ever encountered this weird behavior?

  I think I knew the people. Article 2.7 of the RFC section https://tools.ietf.org/html/rfc3927 which States that to 169.254.0.0/16 packages be sent to layer 3.

  Do not know why some devices transmit these packets, but it seems that best practices is for devices of L3 to drop packets that have 169.254.0.0/16 in their source/destination IP address fields.

• Asynchronous signals and variable waveform

  I am receiveing of data of a piece of software outside of my control via a data Jack. This software gets data of a piece of hardware for the acquisition of data via a serial bus.  It is known to drop packets, but each packet sent (2 per second) has a time stamp.  If I lose a bunch of data, there seems to be no way of setting T0 in the waveform data, so that the missing data are ignored rather than simply added to the next good data.  How to keep track where complete with zeros, lack of time in the waveform data?  Here's a VI showing the problem.

  Hi manjagu,

  What Fan Ravens said is correct, T0 in the waveform data is the moment of the first data point.  This means that you do not want to change this value, but rather your data to all zeros as mentioned.
