Cisco WAN :: Backup DHCP Sever In 2901 As A Same IP Address Generation?
Jul 1, 2012
I have two routers 1921 and 2901 and both of them are connecting to one Reliable Internet Line from one ISP. 1921 master router and 2901 as a Slave. this is my question, how i can make a Backup DHCP Sever in 2901 as a same IP address generation?
Example :
1921-------> Ip Generator 10.1.1.0 /24
2901-------> Ip Generate 10.1.1.0 /24
both generate same ip address, when the Master is lost, Slave could be Covered the LAN.

We have Cisco 3750G switches and have them setup to use Cisco ACS 5.2.0.26.5. Some switches after they are restarted and we know that the config is saved the server address for the AAA authentication is dropped. We are running IOS c3750-ipbasek9-mz.122-40.SE. I have started to upgrade switches to c3750-ipbasek9-mz.122-50.SE5 to fix an issue with reporting high drops in Solarwinds.

So I've decided to utilize 802.1x on a switch module on a 2901, reasons being for mobility for a laptop and network security.
However, the 802.1x authentication occurs over the VPN Tunnel (over the Internet). What our concern is, what happens if the Internet or Tunnel goes down? I know that 802.1x does not authenticate against the IOS local DB, so what would be another option in case this scenario happened?
There will only be one device authenticating (maybe 2) and they are 2 HP Windows 7 laptops.

I need another set of eyes on my config. I am trying to set up my router for a basic connection for the time being. I set my gig 0/0 port to dhcp I see traffic being sent and recieved but I can not ping 8.8.8.8. I am connected to a basic comcast modem from 0/0 I have also tried setting gig 0/0 to 100 full. I do have IP routing enabled. I believe I have my acl's configured correctly. I am wondering at this point if I need a static block of IP's from comcast.
hostname vpn-router-2901
username ****** password *****
enable secret *****
[Code].....

i'm interested if it's possible to set the NTP server via DHCP on an 2901 Router with 15.2(2) image.
i configured the interface gigabit 0/0 as dhcp client. The DHCP Server sends to me DNS, Default GW and NTP. All is working fine, but the NTP will not be configured. i tried to add an DHCP option request, but there is no NTP (42) value. [code]
is there any way to add the value NTP (42) for the DHCP request or isnt it possible?

I installed a new ASA 5512-X over the weekend for a client. Their backup ISP connection is DHCP based. I need to use the 'dhcp client route track' command on the interface, but it is not available. However according the all the documentation I am looking at and even the ASDM says it should be available.
This is the version of ASA and ASDM they are running:
Cisco Adaptive Security Appliance Software Version 8.6(1)1
Device Manager Version 6.6(1)
I did upgrade to the latest ASA software, so has this command been removed? If I do a '?' in the interface, there isn't a 'dchp' option.

How do I do a remote backup to an IP address? I am using NAT.I will be using port forwarding.I am using the windows "Add Network Location" wizard.I typed in my router's IP address, and it doesn't like it.I would like to run a backup by selecting the destination as this network location, if possible.

I had a DI-524 for years and I had no problem. My girlfriend wanted more range /speed for her netbook, and bought a DIR-655.
Had no problem with the netbook (acer One) and the Wii. But the Iphone 1st gen (cracked, but working good up to now) won't see any Wifi.
What to say. I have to read the F* manual, I know. But Geez. "The high end" said the guy at the store.
I should have search the web a bit more before buying because this subject (iphone connect problem) is a popular topic. [URL] won't change a thing. The Iphone don't see the wifi network.
Hardware Version: B1 Firmware Version: 2.00NA

AVG is disabled on the PCs.

Anyone having problems connecting N150 router to a 1st Generation Nest Thermostat? Nest support says it's a problem with them not conforming "to the TCP/IP specifications around Network Address Translation (NAT) timeouts and are disconnecting Nest too soon". Any way to work around this problem until/if a firmware update fixes it?

I have a DSL line at work that we use to test external services provided to external users on our primary Internet circuit (Citrix, web applications, etc). Because this DSL line is for testing only, we want to lock it down so the only destinations allowed through the firewall are our own IP spaces.
I purchased a WRVS4400N for this purpose, thinking I could use the IP based ACL list to create these restrictions. However, every time I try to create an ACL, the internet slows to a crawl, and many sites don't come up at all. This occurs even if the ACL rule I add is a simple "allow any any" rule similar to the default rules.
Is this a known issue, or am I configuring something incorrectly? Here's an example of a rule I'm using (IP not real):
Action Service Source Interface Source Destination Time Day
Allow All Protocol LAN ANY 1.2.3.0/255.255.255.240* Any Time Every Day
I also get the problem with a simple allow from a single IP (mine) to any destination, without any other rules enabled.
implementation of the ACL ruleset on these routers?

I have a cisco 850 that is not getting a WAN ip address thorugh DHCP. I have FE4 (The WAN port) set to get an ip address via DHCP, but when I do a test connection from CCP I get this error: Checking interface IP address…failed.No Ip Address for the interface has been obtained. The interface is configured to obtain an ip address through dhcp. The remote end may not be configured with a dhcp server or the dhcp pool may be empty.
Please contact your ISP or WAN administrator and check if the server has been configured to lease ip addresses to the client’s connection through DHCP. Retest connection.I know that the modem is providing an ip address via dchp, because I can plug my computer directly into the modem and get an ip address, so I think I may have missed a setting on the router. Here is he running config: [code] I think the problem may be the Firewall is not letting dhcp through (even tough I haven't set it up yet, and there are no rules in the firewall yet). But I'm not 100% sure about that.

I am running a Dell Inspiron 530 with Windows XP SP 3. My computer is displaying cannot aquire network address, can't contact dhcp. I have already had the modem and ethernet cables tested, they're fine, and I have tried replacing the network card, no luck. I have also run ip config renew and replace as well as ipconfig/all everything was zero. I checked the startup menu and all the appropriate network apps are marked started and automatic.

I disconnected and reconnected the powercable while holding on to the setup button until system, alert, setup go amber. The system led light began blinking green. I waited until one of the leds lights on the ports starts blinking green I then connected the ethernet cable connected to my pc. I made sure my lan connection on my computer was set to dhcp.In the docs claim it should take about 1 minute to grab a new ip address. After a few minutes i check the ipconfig on my pc and I get the apipa address.The setup light on the switch remains green while system is amber. The led for port 1 stopped blinking and remains green.My pc is not grabbing an ip address I don't know what else to do.

I just tried replacing a cheap domestic router/switch with an RVS4000 V2 on our work network. This has a WAN connection to a cable modem for internet access via a dynamic IP address.
When I first connected the RVS4000 it got a WAN ip address via DHCP of 192.168.100.11. This is the type of IP address we get when there is an upstream problem with our ISPs cable network, and sure enough we had no internet access. The RVS4000 was set to use DHCP on the WAN interface. So I logged a support call with our ISP but they said there were no problems at their end.
I then swapped the RVS4000 out for the original router. This worked fine and got a WAN DHCP address of 77.xxx.yyy.zzz as it should. Swapped back to the RVS4000 and back to the same problem of getting a 192.168... address.
So, I downloaded the latest firmware from Cisco, which was V2.0.3.2 and flashed the RVS4000.
I then tried again connecting the RVS4000 to the cable modem but this time it would not get any WAN DHCP address at all. On the Status/Gateway page of the web interface it said that the WAN interface was down. However, on the front panel there was a yellow light indicating a live connection on the internet port.

I'm working on a BoM for a customer and i need to offer an ASA5525-X pair in HA with AVC and WSE subscritption, I've two question:
1) In order to use AVC and WSE I need the ASA bundle that includes the SSD HD right? (ASA5525-SSD120-K9)
2) In order to have both ASA's in HA, do i need to order two Suscriptions (ASA5525-AW3Y-PR) or only one that is "shared" in the cluster?

I know DHCP can assign more than just address, mask, and gateway. It can also assign a hostname, and DNS. Does anybody know if it can also be used to assign an SNMP address?

I have 2 computers that cannot/will not acquire an IP address from my DLink router.There are 2 other computers that aren't having any problem at all...so I assume that it is not a problem with the DHCP service of the router. The 2 computers are laptops: one netbook running Windows XP and another standard laptop running Windows Vista Home Premium x86. Both computers are running McAfee and I have scanned with McAfee and Malwarebytes, and both are malware-free (no infections were found on either system on first scans...so it's not like I'm dealing with a system that has had infections removed). When connected to the network, they attempt to acquire an IP address, but cannot for some reason and then Automatic Private IP Addressing takes over and they come up with a 169.254.x.x address. I cannot figure out why this takes place, as I have gone through Winsock repair, uninstalled and reinstalled both network adapters (ethernet and WLAN) on both laptops and nothing seems to make a difference. I have even tried disabling APIPA by adding the "IPAutoconfigurationEnabled" DWORD value in the registry......still the same. I have manually configured the adapters with a static 192.168.0.x address, and I can begin to communicate on the local area level...but still cannot establish any kind of Internet connection.

The laptop can connect to the internet using the wifi card. However, it cannot connect to the internet when using the wired connection but it can be pinged from other machines at work. The NIC does not pick up a different IP address even after releasing and renewing the IP address through cmd. I have uninstalled and reinstalled the NIC. The NIC is working because when I set a static IP address the machine can connect to the net. Using DHCP it goes back to that same IP address. I have tried a winsock repair as well with no go, as well as taking the machine off the domain and re-joining it. Is there something I can do on my end to get a different IP address through DHCP or do I have to get a Network engineer involved? This is a machine on a corporate LAN?

I am using Windows 2011 SBS and Windows 7 clients.My server has a DHCP range of 192.x.x.150 to 192.x.x.199 and all other I.P. addresses are static. On a workstation located at I.P. 192.x.x.13 I am seeing an address conflict.When I perform an "nbtstat -a 192.x.x.13" command from the server I am given the logical computer name of a staff members personal laptop.Investigation of the laptop reveals that it is set to DHCP, and clearly the address of 192.x.x.13 is outside of my servers DHCP scope, so this I.P.should never be assigned, let alone in duplicate.I Google this topic before posting, and it was suggested that IPv6 could be having an adverse affect. I determined this because I performed a ping on the laptop and only got a MAC address back rather than an I.P. address.However after unticking IPv6, and rebooting, the laptop is still causing havoc.I can set a static I.P. address on the laptop, however this is not ideal.

problem is my brother has been playing with its config page. he changed the IP Address of the modem and disabled DHCP. he forgot what IP Address he inputted on the config page. I tried resetting the router with the small button on its side. Nothing happens. all the lights blink when i pushed the reset button for 10 sec. but nothing happens. i still can't access its default IP which is 192.168.1.1 IS there anyway to determine its IP Address even if DHCP is disabled ?
