C2950 IOS for DHCP Snooping and DAI

hi all,
anyone knows what image i would need for my 2950 to enable DHCP snooping and DAI features (just for lab purpose)?
or are these features just available on the bigger modular switches (4500 and 6500)?

Hi Alain,
Thanks for this info! I've read you're CCNA Security.
Just curious, are you gonna write your CCNP Security soon?
Could you recommend a good lab switch for SECURE?

  • Help understanding DHCP Snooping and Dynamic ARP Inspection

    Please help me to understand DHCP Snooping and Dynamic ARP Inspection.

    HI Ezra,
    In simple words:
    DHCP Snooping is a feature which is available on switches. This feature is used to prevent rogue dhcp server attacks.
    In the diagram, a valid dhcp server is connected to the network. The computers are suppose to receive dynamic ip addresses from the valid server. An attacker implants a rogue dhcp server on the network as shown in the diagram. The following steps are followed for a client to receive an ip address from a dhcp server.
    When a client (computer) is connected to the switch and is configured to receive a dynamic ip address from a dhcp server, the dhcp service on the client, sends out a DHCP Discover packet, searching for servers on the network. This packet is broadcast in nature. DHCP servers on the network, would respond to the DHCP Discover packet sent from the client. In the example, both the DHCP servers would respond to the DHCP discover packet. The client would process the first packet it receives. If the response send by the rogue dhcp server reaches the client first, then the computer would have an ip address provided by the rogue dhcp server.
    To prevent this, dhcp snooping is configured on the port on which the valid dhcp server is connected to. After the configuration is performed, no other ports on the switch would be able to respond to DHCP Discover packets from the clients. So even through the attacker has set up a rogue dhcp server, the port on the switch to which the attacker has connected would not be allowed to respond to DHCP discover packets. Thus dhcp snooping thwarts the attempt from the attacker in setting up a rogue dhcp server.

  • Can I use DHCP snooping and IOS DHCP server on the same switch stack

    Hello,
    I am shortly going to be deploying a Cisco CallManager solution for a customer whose network comprises stacks of Catalyst 3850 switches.
    There is no separate core/server farm switch so the CallManager servers, voice gateways and IP phones will all plug into the same stack and be in the same VLAN (not my choice!).
    For security we want to enable DHCP snooping and were planning on using the IOS DHCP server on the Catalyst switch stack.
    Will this work? - when I enable DHCP snooping in networks with separate access layer switches I set the uplinks to the core as trusted links.
    I am not sure whether DHCP snooping will work in this case. Do I need to set the VLAN interface on the switch as trusted, is this even possible?
    Unfortunately I do not have access to a layer 3 switch to test this at the moment.
    Thanks

    Nope.  That's the issue.
    They'll sync on a third device acting as a hotspot, but the device sending a signal is not "on" the network it creates so the airport is all by itself on that network.  At least that is what it looks like to me.  Anyone have another take on it?  Seems pretty silly that an iPad can put out a wifi signal, an Airport Express can receive a wifi signal, and yet there is no simple way to get them to communicate under this particular condition.

  • What is the latest iOS for iPhone 3GS and will there be another update

    What is the latest iOS for iPhone 3GS and will there be another update or is it iOS 6.1.3 and no more

    The 3GS is not listed in the supported list for iOS7. Unless Apple comes out with a major bug fix, 6.1.3 will likely be the last update for it.

  • I have iWork and Ilife, do I have to purchase the iOS for pages, numbers, and keynote too

    I am post Mobile Me and I so do not get this icloud.  I just upgraded my iphoto and my iwork is the latest version.  Do I need to purchase the ios for pages, keynote and numbers too... 

    Yes.
    The apps have to be installed on the Mac and iOS devices in order to open and moodify the documents.
    Why purchase again? iWork apps for Mac OS X are not the same as iWork apps optimized for iOS devices. Two different operating systems.

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)

  • I download the recent ios for iphone 4 and connected to my pc and it wont connect to itunes. What is the lastest version of itunes that DOES NOT support ios 7?

    i download the recent ios for iphone 4. i connected iphone 4 to my pc and it wont connect to itunes. What is the lastest version of itunes that DOES NOT support the lastest version of ios?

    Yes, due to Incomplete Software Update on your iPhone your Device is now in Recovery Mode and you cannot take a Backup now. But if you have taken a backup earlier then you can Restore that backup on your iPhone after you Reset your iPhone to Factory Settings.

  • Sg200-50 support dhcp snooping and dynamic arp inspection?

    do the sg200-50 switches support:
    dhcp snooping
    dynamic arp inspection
    ?? thanks

    HI d.pennington,
    SG200 is L2 switch only.  so this mean switch not support dhcp snooping.  Switch support IGMP snooping, Switch support dynamic arp table.  You can management switch with web page GUI only (CLI) not supported.
    Thanks,

  • How good is the new Adobe Reader IOS for fillable forms and interactive pdfs?

    At last adobe reader for ios has been updated so now fillable forms can be completed on ipad/iphone but how good is it?
    I've tested a form and reset form/print form and save as buttons do not seem to work.
    Form submit seems ok, just wondered what others thought?
    Also the new Adobe Reader IOS is now able to display interactive pdfs with buttons such as go to next page etc yet page transitions do not work? Again whats everyone elses opinion on the reader ios update?

    My preliminary experience is that Reader does better with forms than with interactivity.
    I've written a couple postings on InDesignSecrets.com about PDF readers for tablets. Here's the latest one:
    Finding the Best Tablet PDF Reader
    You should also check out PDF Expert (US $9.99) which handles interactivity better than Reader if that is important to you.

  • I was downloading the new IOS for my ipod and when it was installing suddenly turned off and now it turns on and off without stopping :( what could i do?

    I don't know what to do, cause' now is like non stop i've tried to reset it but is still doing the same. I just wanted to install the new version and it end up bad helppp!!!! pleaseee

    See Here  >  http://support.apple.com/kb/HT1808
    You may need to try this More than Once...
    Be sure to Follow ALL the Steps...
    But... if the Device has been Modified... this will Not necessarily work.

  • IP DHCP snooping, IP source Guard, and DIA

    Hi All,
    I have Configured DHCP snooping and IP source guard and Dynamic arp inspection on my 3560 and 3750 Network Switches,
    on both of them I'm facing that issue. (the printers and access points are configured to get ip addresses via DHCP), but when the lease time expires, they don't get ip addresses, and become unreacheable.
    while all other clients get thier ip addresses normally
    below you can find the Configuration configuration
    ip dhcp snooping vlan 98,105,111
    no ip dhcp snooping information option
    ip dhcp snooping database flash:dhcpsnooping
    ip dhcp snooping database write-delay 15
    ip dhcp snooping
    ip arp inspection vlan 98,105,111
    ip verify trust on all access ports including printers and access point ports
    all access ports are DHCP snooping untrusted
    also when I create a static dhcp snooping binding record for these devices on the switch it resolves the Issue, but when I reload the switch it's removed automatically.
    any resolution will be much appreciated.
    regards,
    Maher

  • ISE and dhcp snooping

    Hi all,
    The ISE configuration validator says we should have DHCP snooping enabled on our network access devices (switches) so we do it. However I have never understood what this accomplishes. (In terms of ISE/NAC. I understand what DHCP snooping is).
    Can anyone explain? Thanks.

    Thanks for the reply, Vattulu.
    Interesting article/section, but I don't see where it says anything about the relationship between dhcp snooping and profiling. It seems to be talking about the use of dhcp snooping option 82 to convey the 802.1x user info to the dhcp server. The dhcp server can then act on this information to assign specific IPs to specific users. I can see how ISE would get this information via ip-helper or maybe by snmp bulk query, but don't understand how that would assist with profiling. I mean, ISE already has the 802.1x user identity from the radius request, right? Maybe you can enlighten me.
    Googling around I found this article/section:
    http://www.cisco.com/c/en/us/td/docs/security/ise/1-1-1/user_guide/ise_user_guide/ise_sw_cnfg.html#wp1059679
    which seems to imply that dhcp snooping info can be used when applying DACLs. Interesting, because I thought that was based on the ip device tracking table only. But, it says that dhcp snooping is optional, and doesn't go into any detail.
    Still digging, I would like to understand this. Thanks for your help.

  • IOS 15.0(2)SE5 DHCP Snooping Problem

    I have just upgraded a single production switch from IOS 12.2(50)SE1 to 15.0(2)SE5 to test out new ipv6 security features that we will soon require for our deployment. upon booting into the newer IOS the DHCP snooping feature stopped working, this caused ARP inspection to start dropping traffic so we had to disable it. after going through the normal troublehsooting procedures (check config, reboot, re-apply config, check clients, renew IP address etc) it still is not working.
    has anyone else experience this problem or anything similar?
    I would be interested to hear from people on recent experiences when upgrading software as we have been having a bad time recently with cisco software across a range of products.

  • Does 3550/3560 support static dhcp snooping binding?

    Hi All,
    I'm currently studing DHCP snooping.
    Just found there is no 'ip dhcp snooping bindg' syntax on 3550/3560, Is there any way to add static dhcp snooping entry?
    If there is no way, and the switch intruduced ip arp inspect and ip source guard, and a untrust port connected to an end host with static IP address assigned, in such situation, is it right that I have to add static 'ip arp inspection filter' and ' ip source binding' to makes the end host can send packet out?
    Thanks for any comments.
    Regards,
    Yi
