DHCP client lease on 2801

I'm trying to configure the DHCP client lease time on a 2801 router and can't seem to find the correct command. I've tried searching the Cisco site and found a command that looked like it would do the job (ip dhcp client lease x x x), but when I tried inputting that into the router it didn't recognize the command.
In looking through the router's commands I've found ip dhcp-client limit lease per x which seems to be an interface command and doesn't sound like what I'm trying to do.
Can anyone help?
Thanks!

Are you trying to configure the lease time assigned to a client from a DHCP pool?

  • Sep 02 20:31:01    Severity:4    DHCP Client lease rejected from IPv4 router addr , MAC addr

    Problem:
    Time Capsule kept loosing connectivity from internet modem. ISP has no records of outages.
    Logs:
    Sep 02 20:31:01    Severity:4    DHCP Client lease rejected from IPv4 <router addr>, MAC <addr>
    Resolution:
    Make sure you TC is not connected to the same coax cable that the cable box is connected to.
    Although, the system may work just fine for quite some time, eventually service will be disrupted by some device attempting to connect over and over.
    For some reason, Time Capsule doesn't perform well when a device attempts to authenticate over and over, even if they device clearly isn't part of the Access Control List or even have the correct password.
    So, in this case the the offending mac address was Scientific Atlanta Device, which was my cable box.
    Regards!

    I have seen the same issue with my iOS and Mac OS devices (iPhone and MacBook Pro). I have written my own DHCP server (http://notebook.kulchenko.com/embedded/dhcp-and-dns-servers-with-arduino) and have had troubles getting my devices to connect (Windows Vista and Ubuntu devices connect fine). I suspect that this problem happens because the DHCP Offer message is sent to a broadcast address, even though (at least in my case) the broadcast flag is off in the DHCP Discover message I see.
    Unfortunately you didn't include the Discover message, so I can't tell for sure, but if it indeed has the broadcast flag set to 0, then the server should send the response message using unicast as per DHCP spec (http://www.ietf.org/rfc/rfc2131.txt, section 4.1):
      If the broadcast bit is not set and 'giaddr' is zero and
       'ciaddr' is zero, then the server unicasts DHCPOFFER and DHCPACK
       messages to the client's hardware address and 'yiaddr' address.
    So, it seems like in this case the server may be at fault, even though it would be nice for Mac OS to accept broadcast responses (and would solve my problem too).
    Can someone confirm that Mac OS does not accept broadcast responses to DHCP Discover and DHCP Request messages? Thanks.

  • Dhcp client lease, nat translation statistics

    I am using my 3620 instead of a netgear cable router connected to cablevision.
    1) How can I see when the router dhcp lease ends so I can see if it gets another address? I have seen on past posts that there were problems with this issue. I am using 12.3(13) ios.
    2) How can I see how much memory has been used by nat translations? I have 64Meg of memory.
    Thanks

    Hi csross,
    If I understand you correct this will resolve your issue.
    1) show ip dhcp binding [ip-address]
    It will show you the lease expiration like the output below
    Router# show ip dhcp binding 172.16.1.11
    IP add Hard add Lease expiration Type
    172.16.1.11 00a0.9802.32de Feb 01 1998 12:00 AM Automatic
    Here you go with the link
    http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/hiad_r/adr_s1h.htm#wp1132199
    2) Each NAT mapping uses approximately 160 bytes of memory.
    I am still not sure of the command.

  • EA4500 DHCP Client Table erased

    My EA4500 will periodically clear out the DHCP Client Table and I will lose internet access.This happens once almost every day, normally in the morning. If I can't access the internet I will check the DHCP client table under Status -> Local Network -> DHCP Client Table and it is always empty.
    After I select Setup -> Reboot it will work again - when I look at the DHCP client table it is now populated with all my devices. I am on firmware version 2.0.37.
    Any help would be appreciated.
    thanks
    Bruce

    Thanks for your help - I believe you may be correct.
    I changed the DHCP client lease time from 0 (!day) to 8640 (6 days) and so far no problems this morning. If it lasts another 24 hours I will know for sure.
    I don't think there is a newer firmware version than this: 2.0.37.131047

  • How to configure dhcp client identifier

    Hi Everybody,
    The DHCP client ID is an id that is unique for DHCP clients at least in the same subnet. Usually the client uses MAC-address as Client-Identifier in the DHCPDISCOVER message. The Client-Identifier may be different other than MAC-Address, For example a FQDN name, as per the RFC 2132 Ref, (code 61).+_
    Usaually, we use the following to bind the ip address based on MAC-address
    pntadm -r SUNWfiles -p /var/dhcp -A 10.42.32.86 -i '0:3:ba:a5:a9:93' -a 10.42.32.80
    At server side, I am using the following for specifying the FQDN name.
    pntadm -r SUNWfiles -p /var/dhcp -A 10.42.32.86 -i 'one.atr.com' -a 10.42.32.80
    and at client side, I am inserting the following entry in the /etc/default/dhcpagent file
    CLIENT_ID='one.atr.com'
    But this is not working. What I am doing wrong.
    +1. At the server side, then how to assign the ip addresses to the clients , if the Client-Identifier is FQDN name in the DHCPDISCOVER message other than MAC-Address.+
    +2. How to configure the client-identifier as FQDN name at client side.+
    Please help me,
    Thanks Inadvance,
    Mummaneni.

    Sandman,
    Here is an example of a router acting as a DHCP server. Please remember that you have to exclude IP addresses that you don't want to lease out.

  • WRT54G - won't display DHCP clients, won't let me change port forward

    Just wondering if I need a new router....
    It seems to never be able to display the DHCP clients table any more & when I try to forward a port to a connection, the table says it's forwarded, but it never actually changes it.
    I upgraded the firmware to 8.00.7 (the latest for v8 hardware), did a hard reset and powered off to reset.
    Still no luck....maybe it's just time for a new one?
    Any suggestions welcome.
    Thanks,
    Eric

    I just recently got the same issue in regards to the DHCP on my WRT610n. On windows XP a simple right click of the connection, and clicking repair forced windows to flush the DNS and renew them. After than the machine showed up in the DHCP list on the router again (I guess for some reason the leases suddenly stopped being renewed). Unfortunately this appears to of been removed in Windows Vista and been replaced by some kind of automated diagnose and repair system (If no problem is found it does nothing. Unhelpful). 
    However if you go to start > run > type "cmd" and enter to bring up the prompt, then type ipconfig /flushdns and then after it's complete type ipconfig /registerdns, that should force it to renew it's DNS from the router and it may show up in the DHCP table once more on the router. There's also a ipconfig /renew command that renews all adapters. If you wish to find out more about the ipconfig commands and what each of them does before doing anything, feel free to type ipconfig /?
    Unfortunately I haven't found a way to get my router to keep renewing the leases as usual, so I guess this is just a temporary solution to part of your problem. As for the router going to the wrong IP, I was going to suggest DHCP reservation but I've just found out you don't have that, so instead I've found this quick thread that may / may not be helpful to you as it points out a few interesting rules that Linksys operates by: Click Here
    As for the Port not forwarding, I'm not really sure, I'm just another user with issues of my own. I hope that one of the mods/staff/more knowledgable techi/person on this forum addresses your issues better than I have soon. Though isn't port 80 the default http port, and thus automatically open anyway? Can you even assign that port to anything? I thought it'd be reserved and thus not usable. Have you tried assigning a different port and forwarding that instead? But then again I'm not the most knowledgable of people =P

  • Propagating changes to DNS servers to DHCP clients

    I have a routed network with 8 subnets all served by a 3550 running a DHCP server.  I have 8 dhcp pools set up, one for each subnet.  Currently there are about 100 dhcp clients with leases across those subnets.   I had to change the DNS server list for each of the dhcp pools.  How do I ensure that the new DNS server info gets to all clients?   Will the clients get updated DNS info by virtue of the changes I made to the dhcp pools, or do Ineed to wait until the leases are renewed for the changes to propagate?  If so, short of having each client release/renew, is there a way to force the change?  I know that I can start/stop the dhcp server which I believe will clear all bindings which then in turn will force all clients to get a new lease.  Is there any other way to propagate the DNS change?

    It should change automatically when you modify the parameters. No need to stop/start dhcp for that.
    As as an alternative, it will certainly be updated when the clients are rebooted.
    Best is to change it after office hours, systems will be updated when the users start their PC's in the morning.

  • Why can't Windows 7 be forced to use DHCP broadcast lease renewal?

    I have been going to this coffee shop for 11 years. It still has the same ADSL-based wireless internet service (an old wireless access point connected to the internet through ADSL).
    The ONLY way to communicate with the DHCP server in this wireless AP is via broadcast - lease renewal requests to the DHCP server via direct IP address are IGNORED. On top of that, the DHCP IP assignment pool is rather small, so to compensate the DHCP lease
    time is set to expire every 10 minutes. This is no problem normally, because an active DHCP client will request a lease renewal at half the lease time, or 5 minutes before the lease expires.
    Here is my problem: I had my registry setup to force DHCP broadcast and all was happy - UNTIL Microsoft decided to have an update ADD a "toggle broadcast" flag to the registry and make it impossible to override (so far, in spite of the kb928233
    page that supposedly tells you how to do so). Ever since then, I lose my DHCP lease (and therefore my internet connection) EVERY 10 MINUTES.
    BTW, the KB928233 page has manual registry editing instructions that are so poorly written that at least 2 or 3 different interpretations of those instructions exist. I tried at least 3 different interpretations of those instructions - none worked. A good
    part of the problem is no examples were given of what the resulting key tree should look like in regedit.
    I have invested at least 2 days in Google searches and various attempts to get these flags set the right way again - all to no avail. If I can't figure out how to solve this problem in 2 days of trying something is dreadfully wrong. Again, with emphasis,
    this USED TO WORK until somebody decided to put in a windows update that broke it.
    All I want to know is: for a particular wireless connection how to force broadcast DHCP lease renewal. Some update in the last several months seriously broke that, making it nearly impossible to force broadcast mode.  Oh yeah, it does a broadcast renewal
    request EVENTUALLY - AFTER THE CONNECTION WAS TERMINATED! That is useless - I just lost my remote terminal session or file transfer. I need it to do the broadcast request BEFORE the lease terminates.

    About 3 years ago (IIRC), when I first encountered this problem I used Wireshark to see what was going on. In the link you gave, the second bullet point under item 1 states that a broadcast DHCP renewal request would be given at 87.5 percent of the lease
    time. Wireshark never indicated that such a broadcast renewal went out. It did show the directed request at the 50% point.
    There is one other thing that may be relevant: at the time this problem re-appeared several months ago, a new registry flag also appeared: DhcpConnEnableBcastFlagToggle which was set to 1. I didn't put it there, so I surmise it came from a Microsoft update.
    At this same time the DhcpConnForceBroadcastFlag that I had set to 1 to fix my problem had been reset to 0, thus re-creating my problem.
    I have not looked at the traffic with Wireshark this time around, but I do know that I could use regedit to set the DhcpConnForceBroadcastFlag to 1, but 10 minutes later (at the exact second of the DHCP lease expiration) the connection was momentarily interrupted
    and when I did a regedit refresh, DhcpConnForceBroadcastFlag was now reset to 0 with a new lease expiration and *start* time.
    I suspect Windows rather than the access point for this reason: on a hunch last night, I tried stopping the DHCP client service, using regedit to set the DhcpConnForceBroadcastFlag to 1, then starting the DHCP client service. After this, at the DHCP lease
    expiration time there was no interruption of the connection, the DhcpConnForceBroadcastFlag was still 1 afterwards, and the DHCP lease time had been extended another 10 minutes with no new DHCP lease start time.
    So now my problem appears to be solved once again - and hopefully not temporarily this time.
    The laptop I am using has Windows 7 Home Premium edition with SP1 on it with all the latest updates. It does not appear to me to behave in the manner given in your TechNet note on Lease Renewals. If it would behave that way, I would not have had this problem.
    I am fully aware that the KB I list is for Vista - it was the only information I could find in what otherwise appears to be a void of information.

  • AirPort Extreme (n model) doesn't show all DHCP clients in client list.

    Hi all,
    Wondering if anybody can confirm or deny this occurrence. I noticed that when plugging DHCP clients into the ethernet ports, those hosts do not show up in the DHCP client list. They do appear to get a valid address and work fine, however. I still intend to test whether or not I can assign a static IP to the ethernet client MAC addresses, but I assume that will work fine as well.
    In my opinion, if this is confirmed it should be addressed as a bug (albeit minor). Otherwise I'm very pleased with the new Extreme, by the way. Other issues that I don't like are more a matter of convenience than necessity.
    Mike
    MacBook Pro   Mac OS X (10.4.8)  

    Ditto to all of the above, but I've got another, maybe related, question.
    I have my HP printer hardwired to the router. It is set for a dynamic IP address, so the question of a static IP not showing up isn't the issue.
    My problem is that I can't get the client ID to show up in the list. The MAC address is there, the IP address is there, the lease time is there. But no matter what I reset, either on the printer or on the router, I can't get the printer name to show up on the list.
    If I pull up the printer in a browser window, it shows the name. I've even tried changing the name a couple of times. Nothing.
    No, it doesn't really matter, it still works fine. But it's annoying to me.

  • Strange DHCP client identifier

    I am troubleshooting DHCP between server and client (both Cisco IOS). I have discovered, that server sees client under completely nosensical client identification:
    R1#sh ip dhcp binding
    Bindings from all pools not associated with VRF:
    IP address Client-ID/ Lease expiration Type
    Hardware address/
    User name
    10.0.6.3 0063.6973.636f.2d30. Apr 01 2001 10:40 PM Automatic
    3062.302e.6332.3838.
    2e31.3637.312d.4661.
    30
    Yes, the client id server sees is "3062.302e.6332.3838.2e31.3637.312d.4661.30" instead of little more conventional "00b0.c288.1671". What's up here? This thing makes manual binding impossible, as that long number is not accepted in "client-identifier" on server.
    Edit: No, I wasn't cut'n'pasting properly, that long client-id can be entered into pool configuration. So that solves the problem, and the only think that remains unanswered for me is what were Cisco thinking, when they decided that client-id is going to be this kind of crazy stuff instead of plain MAC.

    Some Cisco networking devices use a DHCP client identifier format that is different from the format used by networking devices running Cisco IOS release 12.4(1) or newer.

    But, you should be able to bind that full (long) address to the the client IP in your DHCP pool configuration and I've done that before. If you are having problems refer to this link:

  • WRT54G dhcp clients table missing linux boxes - only windows listed

    I've searched the forum and similar messages and other routers mention that a firmware update will fix the problem where not all dhcp connections show up in the status/local networks/dhcp clients table.
    I have WRT54G hardware version 6, firmware v 1.00.06.
    I've looked at the firmware updates and no mention of this problem appears. I don't want to needlessly update my firmware.
    Does anyone know if this problem has been fixed in the latest firmware?

    More info:
    It seems that the linux box (ubuntu 7.04) is using the bootp protocol, not full dhcp. From some reading of the rfc's it seems that dhcp is an enhancement to bootp, and it is valid for clients to request an ip address from a dhcp server (the protocols use the same ports etc.).
    However, bootp does not deal with a lease and since the dhcp client tables list a lease time, I am guessing that this different way of getting an ip address is what is messing with the router.
    On the one hand, it could be said that since it's not a full dhcp client, the router would be technically correct to not show it in the client list.
    But, it does make for a bit of a messy situation as some clients can appear invisible to the network configuration manager. This could be a security issue.

  • Refreshing the DHCP client table

    I just got an EA3500 and I guess I don't understand what "Refresh" does when viewing the DHCP client table under the "Status", "Local Network" tab of the web interface, either that or it's not working.  If I have active wired and wireless clients and I power off the EA3500, wait a few minutes, then power it back on, the table is blank.  If I hit "Refresh" I would expect it to re-populate the table with the connected clients.  For whatever reason, it doesn't.  I have to physically disconnect and reconnect the E-net cable, or power cycle the wireless client to get them to reappear in the table.  Is something wrong with the router or its s/w, or is that not what "Refresh" is supposed to do?
    Thanks in advance for any thoughts you might have.

    When your computer needs an address, it will send a demand to the router using DHCP. The router's DHCP server then LEASES an IP address for a short amount of time. The computer has to RENEW the lease once in a while to make sure the router knows that the address is still in use. Routers like these save the DHCP information in temporary memory only. When you reboot the router, it no longer remembers who has what address until someone renews again.

  • Missing Wireless Devices On DHCP Client Table

    I’ll always have three wired devices connected on my router at all times and other wireless devices but I disconnect them when I'm done using them. I’ve recently left two wireless devices connect all the time but what seems after a week or so all my wireless devices stop showing up on my DHCP Client Table. Even though they stop showing up on the DHCP Client Table they still work fine and are still connected to the internet. I already tried rebooting my router and that seems to fix it. I have an E2000 Router with the latest Firmware: 1.0.04 I haven’t had any problems with disconnects or anything. My question is why is this happening and how do I fix it or does the router not support devices been connected for days? Thanks in advance.

    There is no fix for this problem as it's not a problem. Maybe your wireless devices don't renew the lease at some point but just keep using the current IP address. Maybe it's a bug in firmware. But as you have noticed it does not cause connection problems. I think very often there are glitches in the DHCP table of various routers.

  • How can I force a DHCP client to renew its IP address??

    Hi to all,
    I have installed in a customer, a Cisco 2801 who has configured a DHCP pool. This router takes a reload every month (by maintenance purposes), when it is up (in the network we have AVAYA phones working fine, it's a call center), this phones takes a reload to renew the ip, which is assigned by the DHCP pool.
    The problem is when some phones try to renew its IP address (after the router reload), the phone detects a IP conflict an it forces a reload. This reload normally is in production hours, the agents lose their phones and they can't work......
    There is some option to force the DHCP client to do a IP renewal from the DHCP server???
    Thanks to all.
    Regards.
    David.

    First of all you should investigate what is going so horribly wrong in your network that you have to reload your router every month (and even worse in production hour). If it's an instability, have you tried to update to a newer IOS-version?
    Regarding your DHCP-problem. For that you just have to configure your DHCP-server correctly by specifying a database-agent:
    http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_dhcp/configuration/12-4t/dhcp-12-4t-book/config-dhcp-server.html#GUID-5F022CF5-671E-49E7-8FBD-69997EEBC730 
    With this function the router stores all bindings and knows (also after a reload) which addresses are already assigned to which system.

  • I want to reserve a static IP address on my Airport extreme.  What is the difference between reserving by MAC Address and DHCP Client ID?

    I want to understand the differences in the way you can reserve a static address for a device on the network.  I had previously set the device itself to an address and then reserved it with DHCP Client ID, which I thought was just the devices static addresss.  I'm not sure if this was in fact correct or just happend to work.  I know what a MAC address is, but I'm not really sure what the DHCP Client ID is. So it would be great if someone could clarify it, and the difference between reserving address by MAC Address or DHCP Client ID.

    A MAC address is a unique identification consisting of letters and numbers in a form that looks like this:
    xx:xx:xx:xx:xx:xx
    Every network device has a MAC address, which can be found on a label on the bottom or back of the device. Apple calls this the Ethernet ID.
    A DHCP Client ID is an optional name that you can assign to a device. For example, on your Mac....
    Open System Preferences (gear icon on the dock)
    Open Network
    Click on Ethernet
    Click Advanced at the lower right
    You may be able to edit the DHCP Client  ID here....for example.....you could enter MJ500's MacBook in the space provided. That would be the Client ID of your Mac.
