SF300 VLAN IP Address Issues

I have purchased 3 SF300-48 switches to work with my Aironet AP1131AG wireless APs. I have now switched from 1 VLAN for everything to having a Guest_Wireless VLAN 200 as well as the default VLAN 1 for my Corporate_Network. The issue that I am having is that any client on my default VLAN is receiving an IP address from the Windows DHCP server without issue, but when you connect to the Guest VLAN you cannot get an IP address.
So, I also have a Cisco 3560G Router (Default Gateway) that has the same Aironet AP1131AG AP connected to it with the same config files as the other APs and it is working perfectly. I can connect to either wireless SSID (Corp Vlan1 or Guest Vlan 200) and get the proper IP address from the DHCP server.
I attached the diagram of the network below and was looking for help in configuring the SF300 to allow the IP address to be obtained on the Vlan 200 subnet. I also tried connecting my laptop directly into the SF300 and setting the port to access Vlan 200 and I can still not get an IP address.
Any help would be appreciated...

Thank you for taking the time to help me Tom, yes the 3560G has its trunks set to dot11q encap and native valn of 1. The native vlan on the SF300 is set to vlan 1 but I didn't tag vlan 200 to the trunk. I was thinking that if not listed it would pass any vlan info across a trunk and when you tagged it would only limit passing vlan info of the vlans that you specified only.
I will definately give this a try and update this thread.
Thanks,
Aaron

  • 4500 VLAN MAC address issue

    We are facing an issue with our 4500 switch. It is using the same MAC address for all VLAN interfaces, which is causing a problem with our service provider.
    Is there a way to disable this?
    Thanks,

    Fabián,
    I'm afraid that's not possible on a 4500:

  • VLAN network address issue

    we are having 6500 series switch.we are able to telnet the switch with network address as well as with interface address...several vlan are created in this switch.
    now my question is that how can we telnet it with network address...
    help me out plz as soon as possible

    you cannot telnet to a network address. for example, i'm guessing you have 24 bit subnetMask which would make your network address: 192.168.16.0.
    you cannot telnet to 192.168.16.0 BECAUSE it is a network address and not a host able to respond to a telnet request.
    your detail still seems a little fuzzy though...didn't you say:
    "network address is 192.168.16.32...."
    "now i can telnet the switch with 192.168.16.32...."
    and then say:
    "how can i telnet with network address???"

  • System Clean Install because of IP address issues

    HI,
    I just did a clean re-install of Snow Leopard as I had been having the self-assigned IP address issues that so many snow leopard users have been having. Before doing this I used time machine to make a backup of my HD on an external HD and synced my iphone 4 with the computer.
    Now I am hoping to get all of my music back, as well as my contacts, but can't seem to access either of those individually on my external HD using time machine or manually.
    Also I am worried about plugging in my iPhone to the computer and syncing with iTunes, as if I do, I may lose my lifetime's collection of music altogether. Clearly I should have backed up this music on an extra external HD in addition to the time machine backup, but didn't think to do that.
    What are my options? Will it erase the music on my iphone if I sync, or will it pull the music off of it and back into my library? What about Mail and Address book etc?
    any help would be appreciated

    Normal iTunes syncing with an iPhone is one-way - computer to iPhone. If you try to sync the iPhone without your old library then you will indeed wipe everything off the iPhone. There are numerous utilities around such as Pod To Mac - VersionTracker or MacUpdate - that can be used to transfer from the iPhone/iPod to the computer as well as ones that can mount the iPhone/iPod as a disk drive so you can transfer data between computer and iPhone/iPod. For example, PhoneDisk.

  • CIPC Doesnt take voice vlan Ip Address

    ia have my pc (windows) connected to a 3com switch and its takes the ip address from an active directory. but to apply Voice QoS, i need that the CIPC takes an ip address from the voice vlan. placing a 7911 or 7941 in the network plug they take the voice vlan ip address. how i configure the CIPC to takes the voice vlan ip address?

    CIPC is a SW running on a PC and uses the IP address of the PC.
    You just have to configure the the IP address of the TFTP server (Callmanager running the TFTP service).
    Therefore there is no need for the phone to get a IP address from the Voice VLAN.

  • IPv6 Duplicate Address issue

    I'm having a problem involving IPv6 with stateless autoconfig on my network. I have a Cisco 800 series router and we have several VLAN interfaces each configured with an IPv6 prefix. The problem I'm noticing is that whenever any host on the network tries to start up with stateless autoconfig they immediately detect a duplicate address for whatever address they are trying to use.
    I performed a packet capture and what I'm seeing is that when the host selects an IPv6 address to use, it performs the Neighbor Solicitation to check if the address is in use. I immediately see the exact same Neighbor Solicitation message echo'd back with the source MAC being the Cisco router. This causes the host to reject the address as a duplicate since it is receiving a Neigbor Soliciation for the same address it is attempting to use.
    This happens on all of the VLANs I have configured for IPv6. The basic VLAN config is like this:
    interface Vlan109
     description Engineering VLAN
     ip address .....
     ip helper-address .....
     ip nat inside
     ip virtual-reassembly in
     ip tcp adjust-mss 1300
     ipv6 address HE-ENG ::/64 eui-64
     ipv6 enable
     ipv6 nd ra interval 60
    Attached is a PCAP with some ICMPv6 traffic. You can see that the NS messages are duplicated and the source of the duplicates seems to be the Cisco router (70:ca:9b:e0:94:2e). Does anyone know what is going on here?

    Hi,
    Under you interface val config can you try adding:-
    int vlan 109
    ipv6 address autoconfig
    Worth a try
    Regards

  • MAC address issue----Spearman

    Saw your comments on this in the post about the 1.9 bios for neo2platty ....
    I can confirm that My MAC address issue was caused by the bios that you sited in your comments....all F's were written to My nvidia lan too...
    only solution from what I have read is too rma it...'bummer'
    just thought You would like to know....  Your not alone

    I had the same problem yesterday and after many hours searching the web I ended up with this post that made me really desperate... But I didn't give up and while trying a new bios flash because of random crashes when in the bios, I noticed the obvious: you can change the MAC address when flashing 
    use the last version of the dos flasher with the parameters /nvmac:xxxxxxxxxxxx/wb after the name of the bios file; it's explained if you ask the help with the /help parameter. You can find the mac address on a stick on the parallel port.

  • SG300 Vlan IP-Helper Address issues

    hi,
    I am trying to set a ip-helper address on my sg300 though getting the following.

    DHCP server is server 2008 R2 and the range is active for that vlan and can route to vlan and devices set statically fine

    Hi Konrad, DHCP cannot be used for IP helper since the switch has a DHCP-RELAY service.

  • Cisco SF300-24 IP Configuration Issue

    Hi,
    I have purchased Cisco SF300-24 few days before. I have created 3nos of new Vlan. I am not able to assign IP to each Vlan.
    When ever I aggign the IP to the next vlan, previouly assigned ip is not visible.
    need help.

    Hello,
    Do you have the switch in Layer 2 or Layer 3 mode.  In layer 2 mode the switch can have only one IP address.  This can either be static or DHCP.  The switch must be in layer 3 mode to assign IP addresses to each VLAN.  Please see page 258 of the admin guide for how to set IP address for each VLAN.  If you need to set to layer 3 please see page 61.  Also, please make sure your device is on the latest firmware version 1.3.0.59.  If you still have trouble try using a different browser.  I tried this using Firefox and experienced a similar issue to what you describe.  I switched to IE9 and it worked fine.
    If you have completed these steps and are still having difficulties please call the Cisco SBSC at 866-606-1866 between 9am and 6pm your local time for further assistance.

  • Spanning Tree and Admin mac address issues srw2048

    Ok, I have a somewhat complex problem and hopefully someone may shed some light or have an idea as to whats wrong.
    First the scenario:
    I have two Cisco Cat 6509's etherchanneled to each other via two fiber cables.  One of these is the STP/RSTP root.  I have two SRW2048's.. one trunked to each of these 6509 switches.  There is also a trunk between the SRW2048's.  All this is to create a redundant topology so that if one of the switches fail's the others can still forward packets to each other.  Of course the scenario described is in fact a loop that should be handled by STP/RSTP.  I have RSTP enabled on all the switches in the scenario (PV RSTP on the cisco switches as they only do Cisco's brand of per vlan spanning tree).  There are 3 vlan's configured on each of the srw2048's (2,55,96).  There are corresponding vlan's also on the 6509's.  I have put the srw2048's management interface into vlan 2.
    The problem:
    I need to forward packets between the srw2048's primarily and only use the 6509 that is not the root when a failure happens.  I have configured the non-root 6509's spanning tree cost on the etherchannel to be higher then the alternate path through the srw's to the root.  I can hook everything up and view the spanning tree and see that the srw2048's interface that goes to the non-root 6509 is blocked, and all other interfaces on the other switches are forwarding.  I can in fact ping and get to the admin interface on all the switches.  Then for some strange reason the admin interface of the srw2048 plugged into the non-root 6509 stops responding.  If I disable either the interface its plugged into on the 6509 or the other srw2048 everything starts working again.  Sometimes it responds after many failures for no apparent reason.  I looked into the mac-address table on the 6509's and they are conflicting, pointing to each other for the mac-address of the broken srw2048.  When I clear the mac-table the admin port comes back for about 5 seconds then again goes dark.  When reviewing mac-table on the 6509's they are back to pointing to each other.  The odd thing (although I haven't confirmed this completely) is that hosts placed into vlan 2 on that same srw2048 seem to work fine.  If there was an STP loop or something misconfigured, I would expect it to effect any host in vlan 2 or the other vlan's for that matter on the srw2048 that stops responding.  Alas, I am stuck because I need to manage this switch remotely.  My only thought is that for some reason even when the STP status is blocked the broken srw2048 is still sending out arp's of its admin interface and bypassing the STP protocol.  I have no way to confirm this, but maybe someone has an idea as to what I'm doing wrong, or otherwise offer a solution.  For now, I simply removed vlan 2 from the 6509 that the broken srw2048 is plugged into and everything seems fine.
    My apologies for such a long post, but this is somewhat complicated.  Thanks in advance for any info.

    To follow up, I had a ticket open with Linksys about this for about 3 months with no resolution.  I submitted packet captures, stp outputs, etc and no luck.  I gave up and basically had to revert to a manual failover for redundancy.  It's no perfect or fast, but it works every time.
    Unless linksys issues a firmware upgrade with this as a fix, I doubt we will be able to ever resolve this on our own.

  • Client IP Address issues

    Just starting to put a Cisco Wireless infrastructure in place, currently just testing every thing.  Here is my issue.
    After I create a WLAN, bind it to the VLAN I can authenticate but can't get an IP address.
    Now if I bind the WLAN to the same VLAN the AP is on, I can get an IP address.
    I do have the DHCP IP configured under WLAN as well as interface, I tried it with just configuring it on the interface but no use
    I tried DHCP proxy enabled and disabled
    Also want to mention that the AP is connected to a switch and the switch port is setup as an access port on VLAN130.

    what happens if we assign static Ip address?? are we able t oping the Default Gateway?? or from the DG are we able to ping the client??
    Normally the LWAPP in local mode will be in the Access Port.. not trunk... so if you assign vlan 130 on the switch port then the clients connecting to VLAN 109 should also get the IP since its LWAPP tunneled.. So from my understanding.. you are configuring VLAN 130 on the switch and connecting the AP and the VLAN 109 guys are not getting the IP where in VLAN 130 guys are getting the IP?? please correct me if my understandings are incorrect..
    >> in this case.. i have a question.. To what switch is this AP connected to?? any small business switch like CE 500 or anything better than that?? like 2960 and so on..??
    >> Are we able to ping the Default gateway from the WLC and the Client (the interface VLAN which is facing the issue )??
    >> check the switch port configuration on which the WLC is connected and make sure the problematic VLAN is allowed.. or on the switch check if we have that VLAN in the VLAN.dat allowed.
    Lemme know how this works out for you!!

  • 802.1X dyanmic VLAN assignment DHCP issue (Vista client)

    I am labbing dynamic VLAN assignment and have run into a small problem.  The switchport is succesfully changing to the new VLAN, but my test PC seems to get an IP address in the native data VLAN before being moved to the new dynamic assigned VLAN.  So when the switch changes the VLAN the PC keeps its old IP address and nothing talks any more.
    Is this a Vista issue?  I thought all of these problems were just issues in XP?  Do I need to tweak any interface dot1x timers?
    (Cat3750 with 12.2.55 / ACS5.1.  Everything else is running fine by the way.)

    if i do a show run on the switchport the config hasnt changed, but i dont expect it to, as its not a permanent config change that you would want to be saved by a different admin user saving the config.  You can see the debug report it is changing the VLAN:
    Apr 19 09:22:56.263: %AUTHMGR-5-START: Starting 'dot1x' for client (0014.c209.896f) on Interface Gi1/0/19 AuditSessionID C0A8FE250000000900291476

    as well as checking with the show int switchport command and it is in v12 which is the dynamically assigned vlan
    DHCP server is the cat3750 for all local VLANs

  • DHCP server and ip helper-address issue

    Question,
    By accident I had configured an IP HELPER-ADDRESS on a VLAN interface pointing to a DHCP server with an IP addrees in the same VLAN ( ip subnet ).
    Some users had complaints and there were BAD ADDRESS entries in our DHCP server registered.
    Can anyone explain to me why this is an issue please ?
    My guess is that the the DHCP server receives the DHCPREQUEST from the client via the braodcast request and via the unicast request from the ip helper-address configuration. But does this really interfere with the DHCPACK and DHCPOFFER packets afterwards ?

    Alex,
    I've not been able to capture the network packets but I can understand if the server would send DHCPNACK requests ( wxhich would be a normal process ).
    I just don't understand why so many users suddenly have issues and my DHCP scope is filling up with BAD ADDRESSES.
    My assumption is that the client receives 2 valid DHCP responses ( one form the actual DHCP server and another one from the router, acting as DHCP relay agent ) and acknowledges them, but the DHCP process is somewhere corrupted ( either on the DHCP server or the DHCP client ).
    I want a technical explanation for this issue :-)

  • DHCP server bad address issue

    Hi,
    I'm having an issue with ip address conflict or "bad_address"
    I've checked for rogue dhcp server with wireshark. One issue i'm having is that the mac address of the device getting the bad_address issue on the dhcp server is only 8 characters. There is no such device like that on my network. This would be occuring every
    other week. Removing it solved the problem, but how do i find the culprit of this problem?
    Thanks.

    What confuses me, is that it works fine at one site with all of your Windows 7 machines, but not the other. So something up with the DHCP Server? As I asked before, is it multihomed? If RRAS is installe on it, that constitutes multihoming, too.
    OTH, Windows 7/Vista's DHCP Lease behavior is a bit different than XP. And keep in mind, we can't discount server side issues, yet, or we can look at this as a combo of the facts. In addition, if anything is on a VLAN, then that's another layer of "something"
    else that we need to look at.
    Anyway, here are my notes on Windwos 7/Vista DHCP lease behavior differences:
    Windows 7 DHCP Lease Behavior is different than Windows XP upon startup
    DHCP Client Behavior
    http://blogs.technet.com/b/networking/archive/2009/01/29/dhcp-client-behavior.aspx
    If the DHCP client obtained a lease from a DHCP server on a previous occasion, and the lease is still valid (not expired) at system startup, the client tries to renew its lease. 
    If, during the renewal attempt, the client fails to locate any DHCP server, it attempts to ping the default gateway listed in the lease, and proceeds in one of the following ways:
    •If the ping is successful, the DHCP client assumes that it is still located on the same network where it obtained its current lease, and continues to use the lease as long as the lease is still valid.  By default the client then attempts, in the background,
    to renew its lease when 50 percent of its assigned lease time has expired.
    •If the ping fails, the DHCP client assumes that it has been moved to a network where a DHCP server is not available.  The client then auto-configures its IP address by using the settings on the Alternate Configuration tab.  When the client is auto-configured,
    it attempts to locate a DHCP server and obtain a lease.
    As a workaround, you can force a Windows Vista or Windows 7 DHCP client to keep the old DHCP lease by adding registry key “DontPingGateway” if connectivity fails, see the resolution in the KB article below:
    Windows Vista does not keep its DHCP IP address if a DHCP server is not available (works for Windows 7, too):

  • Multiple IP Address Issues

    This has been driving me crazy for a while now.  Mainly because I solved this once for myself earlier this year!  I cannot find the solution again and I need help.  Two Snow Leopard clients I have, (10.6.6) are returning three IP addresses in DNS.  One for each is their correct static IP, the other two are odd. 
    For example (not actual IPs):
    PowerMac1.domain.com is returning 192.168.1.38 (correct), 192.168.242.1, 192.168.138.1
    iMac1.domain.com is returning 192.168.2.13 (correct), 172.168.28.1, 172.168.16.1
    This happens with Windows nslookup or Apple's dig, of course.
    Like I said, I managed to fix this on another system (running Snow Leopard server) a while back.  I believe it was an SMB issue?  Don't really remember.
    Any help is greatly appreciated!
