• Remove the entry from the ARP table

  I need to create a program to remove an entry in the ARP table in Windows 7 with LabVIEW and TestStand.  The test that I develop contacts ESA via Ethernet.  Each HAD has the same IP address at the beginning but different MAC addresses.  I note that there may be long delays in test is running when you try to connect and remove the previous entry in the ARP table seems to help.  But now I have to do it manually through the command line.  The command 'arp d' requires elevated privileges.  I had a hard time getting LabVIEW to raise the system exec.  Does anyone have an ideas? Is there a .NET access to the ARP table?

  Thank you

  I'll try to look into ARP sync settings setting in Windows.

  We have suffered from various problems of connection-performance TCP a few years ago and our solution was to change the default number of TCP sockets and delays (we knew port exhaustion). The tweeks eliminated most of our problems, no changes to code LV/TS not required.

  I tried to find info on ARP parameters for Windows 7, but it seems that there is much less info available that ther is for XP.

  Key words of the most common registry for older versions of Windows have been 'ArpCacheLife' and 'ArpCacheMinReferencedLife.

  EDIT:

  These parameters were apparently kidnapped in Vista. I found this on the site of $ M; they can apply to later versions, as well as M$ is a request for change to the management of the ARP...

• SFFT Table Overflow

  Hi I hope someone can help me with some problems with a switch that we use.  We have a SG 300-52 which is used for untagged inter vlan routing on a network of more than 100 users with and I wonder if the switch is appropriate for the task.

  The log file continues to display the following messages:

  2147480831 2012-Jul-06 13:14:45 % of IPFFT-W-SFFTREDYELLOW warning: IP SFFT Table Overflow, aggregated (1)

  2147480831 2012-Jul-06 13:14:45 % IPFFT-W-SFFTREDYELLOW WARNING: IP SFFT Table Overflow

  Even if I restart the switch messages will be begin to appear after less than a day.  Which I know is a table overflow I don't know how to solve the problem.

  With regard to the performance on the new VLAN (vlan10) switch the SG300-52 is configured, because there are only a few servers, but there is no domain controller on this vlan, so the switch must manage all routing for DNS, WINS etc.  Transfer speeds are excellent, but when a user uses sometimes vlan10 in windows Explorer frequently the screen is paused for up to a minute before displaying the network according to the number of drives are mapped to the vlan (vlan1) original.  It is a problem that I'm more accustomed to occurring because of shortcuts dead so I'm surprised that it goes through the VLAN, so I'm quite willing to tell it isn't a problem to switch, but it happens on vlan10.

  Initially, the idea was to have a new domain controller on the new VLAN, but due to problems with the new Server 2008 domain controller and the discovery that production used even a few old pc for you connect meant the plean is pending.

  Is anyone able to shine some light on the issues I'm having?

  The switch was configured using these guidelines:

  http://www.Cisco.com/en/us/Tech/tk389/tk815/technologies_configuration_example09186a008019e74e.shtml

  Robert, this means that small business switches are good edge for the major networks and switches of good heart to small systems. For this particular scenario, I would recommend that your main switch should be a catalyst switch then you can drop the SX300 switch access layer position.

  For networks of small size (less than 100 users), SX300 switches perform quite well is not a bad switch, it is simply not designed for something bigger.

• 4 devices using the same mac address in the ARP Table. Explanation

  Please tell me why four devices connected to the router shares the same mac address was shown on the arp table? I know this has to do with the firewall and owner of listening devices, but why all using the same mac address instead of him? I'm trying to understand this scenerio. Please advice.

• ARP table corruption. Command alias

  We use a PIX 501 and we saw very odd behavior that I can not explain, and have never seen mentioned anywhere. We have a lot of following proceedings on our firewall:

  access-list 100 permit tcp any host 216.x.x.x eq www

  public static 216.x.x.x (Interior, exterior) 10.10.10.10 netmask 255.255.255.255 0 0

  alias (inside) 10.10.10.10 216.x.x.x 255.255.255.255

  216.x.x.x is a registered domain name. It all works very well with one exception. Every time that a server inside the firewall performs a DNS lookup on the name it's given the properly aliased internal IP address. However, as soon as this product to the entry in the arp on demand (Win 2 K Server) table for the named server becomes the value the MAC address of the firewall instead of the MAC address of the server. This means that this server cannot participate in the network more. To resolve this, we are obliged to perform an arp static mapping for any server with an alias on all servers in our network.

  Anyone has an idea why this happens?

  You may need to disable the proxy arp on the interface?

• Unknown Apple IP addresses in the ARP table?

  Given that I added two Apple TV 4 to my network via ethernet and using IP addresses static, I notice several entries in an IP scan for unknown IP addresses that seem to be related ATV equipment.

  I am at a loss for why this is happening or how to fix it.  I unplugged my ATV gear and restarted the routers and switches, emptied of the ARP protocol on mac I use to scan ports, but registrations continue to show.

  It is an example of what I see.  Appreciate any ideas or suggestions.

  Strange. We'll see.

  You have configured your DHCP router in order to exclude the static address of the DHCP pool? Why use static addresses, anyway? Are the addresses reported in DHCP pool?

  You have configured the static addresses in the ATV? As well as the correct values for the gateway and the server names?

  These are obvious questions, but need to check.

  They are all the last time at the same time, which I suppose is the time of the scan. It would simply mean their leases have not expired. What is your DHCP lease?

  Do you use the wifi for devices that come and go? This could explain some distribution of values of intellectual property.

  Do you use AirPlay to a device on a wifi network for an ATV on another network? In other words, you need bluetooth to make AirPlay work?

• How to add a leader of overflow AND repeat an overflow table header line

  I created a dynamic PDF form that contains a table. The table overflows perfectly on the next page when enough lines is added, but I wish that both the leader and title the line table to be repeated on each page header. Is this possible?

  Of course it is. Just eliminate the margins of the HeaderRow subform.

  As for what I did, I just created as second header with everything you want to show on the headers when overflow and set the original header to appear only on the first page and the second header is displayed on the overfowned Board.

  To do this simply select the header "-> properties-> object-> paging" and you will find her understand this about page xxxx options.

• There is a maximum amount of hosts for Cisco SF300?

  Hello world

  I m using a Cisco (SRW224G4P) SF300 in my network and I m using Vlan´s.

  I m a lot of loss of packet´s in the network and the users are facing in the absence of performance.

  There are altogether seven switch´s in the network, 6 SF200 Cisco as 'access' switch´s and 1 Cisco SF300 as the 'core' switch.

  It has almost 170 devices connected to the network, mainly IP cameras, other devices are the DVR´s and the NVR´s, a server a certain stand-alone.

  Thing is I m, including the loss of packet´s, and I found this alarm in the SF300:

  2147480831 2012-Jul-06 13:14:45 % of IPFFT-W-SFFTREDYELLOW warning: IP SFFT Table Overflow, aggregated (1)

  2147480831 2012-Jul-06 13:14:45 % IPFFT-W-SFFTREDYELLOW WARNING: IP SFFT Table Overflow

  Some people say this switch (SF300) support´s only 100 guests and that s why I m get this alarm and lose packets.

  But I can't find the limit of host´s in the specification of the switch in any document from Cisco.

  Think you on this?

  There is a limit of 100 guests for this switch?

  Thanks in advance!

  Carlos

  Hi Calavalle, the module layer 3 can only the hardware switch 100 until it starts to change software. The switch can support up to 510 IP addresses but anything over 100 have wait performance degradation.

• WiFi loses connection intermittently and the erasure of the arp arranges

  This has been asked before many times, but none of the above worked for me so far.

  I have a MacBook Pro with El Capitan on it. From time to time, usually 5 to 10 minutes,

  my connection drops and I can browse the internet. As:

  4 bytes of 8.8.8.8: icmp_seq = 7646 ttl = 53 time = 13,091 ms

  64 bytes of 8.8.8.8: icmp_seq = 7647 ttl = 53 time = 17,035 ms

  Shooting, then turn on the WiFi will fix the problem, but I tried to limit the problem

  and I discovered that deleting IP of the route in the arp table will also fix connectivity

  immediately:

  $ sudo arp d 192.168.0.1

  64 bytes of 8.8.8.8: icmp_seq = 7725 ttl = 53 time = 15,173 ms

  Deactivation of unicast arp has NO had no effect either:

  $ sudo sysctl-w net.link.ether.inet.arp_unicast_lim = 0

  Notes:

  -J' have two MacBook Pro at home. Other works without problem.

  -My phone and other devices work also with the same router with no problems.

  -The problematic MacBook works with other WiFi networks without any problem.

  What could be the problem?

  Yes, clear arp fix it. Very familiar with it.

  I had this problem for 2 years and more than 2 or 3 MacBooks, on El Capitan, Yosemite, and Mavericks.   I Googled it every 1-2 years months.  I captured packets and tested several access points... The best fix so far... is the arp compensation, and I have the automated at the moment:

  in a terminal:

  While true; make sudo arp - da; sleep 2; fact

  When the window is open, every 2 seconds, my arp table gets undervalued... and if I lose connectivity, the maximum cut is 1 to 2 seconds.

  I noticed that in some places, I don't have the problem... its as if my laptop reacts badly to some other customers on the same WIFI network.  This question makes me crazy, and I can't imagine how was such years.  If I don't fix it manually, I find myself for 30-120 seconds every few minutes.

• N2000 - arp with Enhanced hash mode issues

  Hello

  I want to report a problem, I got after pass a set of three switches the 6.2.6.6 version N2048 to version 6.3.0.16

  After the upgrade, some PC on some VLANs failed their gateway more. I found that these devices don't y mac of the bridge in their arp table. It would seem that their arp requests would be removed in the channel port connecting the N2048 to the rest of the network stack. Add a static arp entry on the affected PC has enabled them to reach their front door.

  I know that there has been a bug (fixed in 6.3.15) with package falls on the port channels using the (strengthened) 7 mode. It gave me a clue and today I changed the mode of hash for 6 (IP Source/Destination and source/destination port TCP/UDP) and I removed the static arp entries, that I had created to circumvent the problem of the day before. Then I could see the bridge as a dynamic desktop entries, as it should.

  It seems that there is always a with improved hash bug in 6.3.0.16. I'll be happy to send my config and / or more information on demand to help you study the problem.

  Kind regards

• dynamic inspection of arp and arp traffic

  Hello world

  Dynamic inspection arp only offers protection against fake gratuitous arp response by checking the free response against the dhcp binding or she also provides protection against all false arp traffic by checking all traffic against the dhcp binding arp?

  For example.

  H1 - f1/1SW - Dhcp Server

  H2 - f1/2

  H1 mac address is mac1 and assigned by dhcp 199.199.199.1 ip address

  H2 mac address is mac 2 and dhcp IP 199.199.199.2

  SW has following dhcp bindings

  Mac 1 199.199.199.1 f1/1 vlan 1

  mac2 199.199.199.2 vlan1 f1/2

  Let's say that a hacker connects to his office at sw to f1/3.  H1 needs to communicate with h2 but h1 arp table has no entry for 199.199.199.2 (de).

  As a result, H1 must send the request of broadcast arp to 199.199.199.2. The question is: If a wrong answer with its own mac address arp IE hacker craft

  MAC3 199.199.199.2 (where mac3 is the mac address of office hacker), dynamic arp inspection to check this answer arp against the dhcp bindings?

  Thank you.

  What you describe is exactly what wiill DAI protect you against.

  Configuration changed from enable_1 to 13:59:35.590 THIS Monday, November 3, 2008

  I think that version 3.2 can not recover the MIB for ARP, and I found this version 4.01 only. But I was unable to find any kind of upgrade notes here, and we have the control of server farms proyect sttoped for this problem.

  Any who had this problem?

  How did solve you this?

  Thank you!

  Angel,

  You're right, '(IP - MIB) ARP table entries' MIB was introduced in 4.0 (1) and you have to upgrade to 4.0 code to get to the ARP Table via SNMP MIB.

  And here is the document that contains information on the FWSM upgrade.

  When "show arp" switch cisco, the arp table only contain the information on the neighbors of switch, but without guests, why?

  Assuming that HostA and HostB are in the same subnet.

  Because the hostA will arp on the mac address of host b. If hostA broadcast on the local subnet syaing who owns this IP address IE. the IP address of host B.

  Host B repsonds with HostA mac address. The switch if it is a pure layer 2 switch only cares about the mac address and the port, he came above and it should save that it in the mac address table is.

  Do you mean that you do not see the mac address of the HostB in the mac address table?

  Keep in mind that entered mac address get timed in the cache switch.

• FWSM ARP problem

  Hello

  I have 2.3 (3) FWSM Firewall Version with multiple context mode. How can I clear the arp table in one of the contexts (e.g. admin context). Claire arp does not work.

  Thanks in advance.

  Hey Buddy,

  you do not look like in the configuration mode

  Try this,

  FWSM01/admin #config t

  FWSM01/administrator (config) #clear arp

  Let me know if it works or not.

  Enjoy!
