Dec 16, 2010I am using a 1811W and CCP for configuration. I am trying to assign client names to devices on the LAN so that when a network scanner is used, the client name is displayed. I have attached part of the running config after a binding has been done. My assumption is that the scanner should now show 192.168.1.109 as name <Supermicro>, but the name is blank. Is this configured correctly for what I am trying to acheive?

May 10, 2013I configured an DHCP server on cisco 3750 switch . Wher in w3750 gets connected to plain l2 switch 2960 on floor and machine gets connected to 2960 port. [code] Below is the description of problem:
-> The Cisco 3750 switch is the DHCP server. VLAN 108 is named as internet vlan.
-> Ports in Cisco 2960 switch has been configured with "switchport access vlan 108".
-> There were no problems at all and everything had been working smoothly.
-> 3 days back, users started complaining that they couldn't access the internet. Up on troubleshooting the issue, I found out that there was an issue with the DHCP server as the computer couldn't get any IP address at all. After setting static IP address, the internet started working again.
If I bind IP to MAc address reservation on core 3750 switch for some time of moment it works but after that machine gets unreachable .I restarted the 3750 switch and also all the 2960 switches over the weekend, however, the issue still hasn't been resolved yet. I did issue the command "clear ip dhcp conflict *", clear ip dhcp binding * but no joy at all.
Cisco Switching/Routing :: 2960 - Manual Ip Binding In DHCP
Nov 27, 2011WE HAVE cISCO 2960 SWITCHES. this switch acts as a dhcp server for the hosts connected to it. Provided mac based binding to the hosts, with enabled dhcp snooping and IP source guard per interface.' I have a problem with single host couldnt get an ip from dhcp as he binded based on mac: manualip. Here is my config: We have a VLAN99, 70 hosts connected should get an ip based on mac
switch(2960<config>interface vlan99
# ip address 10.10.14.2 255.255.255.0(code)
The above host amit (10.10.14.31 swhould get this ip bindded with mac) but hez not getting manual ip i.e 10.10.14.31, but if an ip excluded from the dhcp free, he can get that ip i.e automatic ip . every other host are getting the ips as binded in the pool manual ip. Checked with
**sh mac-address table dynamic vlan 99 ()
**clear ip dhcp binding * or 10.10.14.31
** clear ip dhcp snooping binding
*** clear ip dhcp conflict *
Tried to change pool names. All these troubleshoot couldn't make me success in providing amit an manual ip.
Cisco Switching/Routing :: 3750x Binding Between A Switch Interface And DHCP
Nov 8, 2011I am looking for a way to bind between a switch interface (cat 3750X) and a DHCP server reply.The switch can operate as the DHCP server .a PC connected to interface Gi 1/0/1 will lways get IP address 10.0.0.1 because it is connected to interface Gi 1/0/1, a PC connected to interface Gi 1/0/5 will lways get IP address 10.0.0.5 because it is connected to interface Gi 1/0/5 and so on... (no matter the source MAC address who sends the DHCP request).

May 30, 2011I have a Cisco ASA 5500 as the main router with a DIR-655 as a wireless access point behind it. DHCP is turned off on the 655 as the ASA is providing DHCP. This worked great for about a year and now suddenly, without any changes, I'm having problems. The only thing that connects without a problem is a laptop, which shows up on the device list with an IP. Other devices have problems. iPhones connect, show an IP on the device itself, but when listed in the connected list on the 655 show no IP. The connection is super slow. An Airport Express will connect, but again, shows no IP in the connected list on the 655. Using the ethernet cable from the Airport Express, nothing can get an IP. I can live with the iPhone not connecting, but the Airport Express not connecting is a major problem. Any reason why this would just stop working one day?

Cisco Wireless :: 5500 / Dhcp Proxy Option In Controller?
Jul 2, 2012While configuring a 5500 wireless controller, i came across this option of DHCP proxy under Advanced tab of Controller Option.It asks for the dhcp option 82 remote id format & the dhcp timeout.
1. What is the significance of this & when do we use it?
2. Also, under each wlan ssid that we create, there is an option of dhcp address required under the advanced tab. Do we need to use this option, if we are defining a normal dhcp pool in our controller for that ssid.

View 2 Replies View RelatedCisco WAN :: 861 WAN Changed From DHCP To Static IP And Now Can't Ping
Jan 21, 2011My old office uses Cisco 861 as a VPN router, with the WAN side setup to receive a dynamic IP assigned by Time Warner cable. Now we switched to a new office, with TowerStream which provide 4G SLA'ed 10Mbit service with static IP, and I get a Cat 5 ethernet down from it.
So all I did, was to go my "interface FastEthernet4", and typed ip address 173.243.123.123 255.255.255.252.Changed speed to "speed 100" and "full-duplex" (as instructed by the ISP).
I also did "ip default-gateway 173.243.123.124", which is the default gate way assigned by the ISP.I also typed "ip name-server 64.17.123.123" to setup the new DNS, am I doing anything wrong? I can't even use the router to ping google, but if I connect the laptop directly to the outside line, then it works, so I know the outside line is good.
Why can't I connect to the internet? I wasted several hours already trying everything in my book to trouble shoot a supposedly very simple configuration change. Do I need to change something related to NAT when changing to Static IP? My NAT was working just fine before when under DHCP.

Cisco Firewall :: Support Of Jumbo Frames On ASA 5500 Firewall Appliance?
Feb 28, 2010Can any ASA 5500 in particular the ASA5510 firewall support jumbo frames (i.e. greater than the default standard 1500 Bytes frames)?. I plan to use the ASAs to setup a point-to-point IPSec tunnel and need an Application frame of 4Kbytes intact and not segment it.I have done little checking on the Cisco Website and see it mention of Jumbo frames on the 5580 on 10Gig interface but didn't see mention 5510. 5580s are way over-kill and expensive for what I need is to run a mission critical one IPSec point-to-point with maximum of no more than 100Kbps so 5510 is perfect for me but not sure if it can carry the jumbo frame?
On the routers and switches it's the MTU settings and they are configurable per interface and I am OK and the circuit is T1 which the Telcos said it's OK since it's physical layer so the only unkown is the firewall.
Home Network :: Static DHCP With DD-WRT?
May 28, 2012For numerous reasons, I want to bind my DHCP clients to static IP addresses, but can't figure out how to do it in DD-WRT.
I've googled, but every link I click times out (for this specific search- my uplink is otherwise fine).
I know I can do it with hardcoded IPs, I'm just curious how static DHCP is done (and yes I am aware that Static is a contradiction in terms of DHCP. I want a given MAC to always get the same IP) and would like to have some info on this.
(call this reserved DHCP if you prefer... )
Static IP From ISP On Windows Server With DHCP?
May 7, 2011I have a machine with Windows Server 2003 running an Exchange Server in a office with 5 workstations attached. The server is being used for a basic outlook calendar across the various workstations, nothing major. Our current ISP provides us with a Static IP address. The party that installed and configured the server set it up to run the DHCP server on the server PC itself. As in, the machine running windows server is also running a software DHCP server for the entire network. THE SETUP: As of right now we have a wall port (internet access) with a cable running to a 8 port unmanaged netgear switch that has cables hooked up to the 5 workstations as well as the server itself. Pretty simple.THE QUESTION: How do I configure the ISP static settings on the DHCP Server portion of the Server PC? We may be getting a new ISP with a dynamic address OR a new static address. WHAT I'VE TRIED: I've tried configuring the IP address on the Server PC the way I would via the NIC adapter settings but it already has a internal IP address from the DHCP Server running on that PC so changing that was no good.

Can't Connect Via Static IP But Works Fine Via DHCP
Feb 5, 2011I am having trouble connecting to the internet, but not my network, when I assign a static IP to my machine. However, when it's set to DHCP, it works just fine.
Pertinent info:
-I'm connecting to a Linksys WRT610N router via a wireless USB adaptor, Netgear WNDA3100v2;
-Service is Time Warner Roadrunner cable;
-There is no IP conflict as I've got DHCP range set from .200-.249 and this machine's static is .100;
-All the other devices in the house are on static starting with .101 up and they all work fine, both wired and wirelessly;

Cabling / Cards :: One LAN Port Using A Static Ip And DHCP
Feb 22, 2012I have my boss's (president of the company) laptop, wired LAN port, setup with a static ip so his laptop will bypass his company's web filter, and was going to let him use the wireless for home and travel. However, what if he needs to use his LAN port on a different network that doesn't support the ip's of our company's network? I need to see if there is a way, utility, or something that can be done to allow him to have a static ip assigned to that port and use DHCP (for when he is on other networks) so he can bypass the web filter.
I have a rule on the FW to allow his static ip to bypass the web filter. I have tried the alternate configuration inside XP and editing the registry to assign that nic dual ips, but I still get blocked on the filtered webpages. For now I have just emailed him the steps on how to switch it manually.

Cisco WAN :: 876 - DHCP Client Injects Static Routes In Config
Aug 8, 2012I have a Cisco 876 router running 12.4.(15)T5, configured as DHCP client. This works nicely.
A Cisco 886 router, running 15.1 software also works with the DHCP client. This also works but has the following strange beheaviour: In the running-config an ip route 0.0.0.0 0.0.0.0 <dhcp assigned address> appears. Also - some other static routes that are in the config using the dhcp keyword are duplicated with the dhcp-assigned address
Now - when a write mem is done, these dhcp-generated route entry's are stored in the startup-config...
This beheaviour is completely different and VERY unwanted. After a change from DHCP server the config will simply stop working, when a write mem was done at the first DHCP situation.
Should we stop using write mem commands when a DHCP client is active in IOS? Is it a bug? Is it a feature?
Cisco Switching/Routing :: 861 Need DHCP Server With Static IP Addresses
Feb 2, 2013I used to use a CentOS self-made server for intranet for my little office, but I bouth few days ago a Cisco 861 router to replace the linux box.
1. I have 2 public IP classes from my ISP. 1 class is limitted to 80mbit upload, the other to 30mbit upload. So I need some sort of DNAT to be able to know exactly which intranet computer uses big internet and which one limitted internet.
2. I need DHCP server and with static IP addresses (one computer must always have the same IP address, etc).. i have my needs for this.
3. Also I need external access to some servers inside (web, ftp, etc) [code]
So far so good, all looks simple and I can achieve this in 2 hours on a centos linux box (correct routes, ip forwarding enabled and few iptables rules for NAT/SNAT/DNAT).
But on this brand new Centos router well, i'm not even successful in pinging the outside world, nor the inside world I'm tired of reading the forums, the documentation..i want (at first) a simple scenario: vlan+dhcp, fa4 with 1 public ip address and ACCESS to the real world. I wasn't able to achieve not even that much. [code]

View 5 Replies View RelatedCisco Wireless :: AP1142 Preferring DHCP Address Over Static Configuration
Jul 30, 2012I'm experimenting a strage issue with some AP1142 that prefer getting new IP from DHCP server rather than using the static ip already configured.
I've got more than a hundred of 1142 APs already conected to a 5508, all with static IP, all working fine for about a year.
As i installed 30 more AP, i enabled a dhcp scope on the controller to give IP to the new APs and when the new aps got registered i changed the configuration to static IP.
The problem comes when some of the older AP than have already static ip are gettig ip from dhcp scope.
If i look at my WCS, it reports that this APS are getting DHCP IP because they cannot reach the controller with their static ip. As this is impossible, because the static ip and the dhcp enable scope are in the same subnet in a layer 2 configuration and with the same gateway. (e.g: old AP 10.10.2.10/16; new AP(dhcp 10.10.3.10-50) 10.10.3.15/16; gw 10.10.254.1)
The problem comes when i disable the dhcp scope, all the older aps that got dchp ip from the wlc scope instead of using their staic configured ip are deregistered. If i reset every ap manually, from the swithc disabling PoE, they start to use the static ip and everything comes fine.
This is happening with about ten of fifteen APs from the 100 installed, that is the strange thing because this seem to be very random as the failing APs are installed in different building and connected to different switches.
As now i have disabled dhcp scope and all APs (old and new) have static ip everything is ok, but i will have to add some more APs shortly and every time i enable the dhcp scope on the wlc
TP-Link ADSL2+ Wireless :: W8960n - Static IP Outside Dhcp Range
Feb 25, 2013Region : Australia
Model : TD-W8960N
Hardware Version : V4
Firmware Version : TD-W8960N_V4_130205_Beta
ISP : TPG
I have an Optus Home Zone (mobile cell tower) that requires ports open.
Port
123 UDP
500 UDP
4500 UDP
I have assigned the Home Zone a Static IP outside the DHCP range and set the above Ports on the NAT, Virtual servers to that IP address.
I have used nmap to scan the ports and it provides open/filtered status for all of them.
Here is the kicker for me, i use a DGN3500 netgear (which keeps dropping WiFi hence its replacement) and enter the ports and it works straight away. Un plug and put the Tp-Link and nothing.
I use Eset Smart Security, could that be the problem?
Cisco Switching/Routing :: 3560 G - Static DHCP Client Drops Connection
May 31, 2012 i am not sure if this is something with my DHCP setup or not, but it certainly seems to be the culprit. I am running a 3560G and using it as DHCP and to do V LAN routing (Geiger protocol). I have 10 pools configured with a few static addresses per pool. Now to get down to the problem. I have a computer (and this problem seems to be a gremlin as it changes what computer is affected quite often) that will connect, get its IP, immediately disconnect, then send out a DHCP req again. The computer has a static assignment in the pool, and for the brief second that it connects, it gets the right address. If i move the computer to another v lan, all works right. If i delete the static entry it will get an address in the right v lan no problem. The command i have been using to add static entries is:
address xxx.xxx.xxx.xxx client-id 01xx.xxxx.xxxx.xx
That seems to have been working on all my static routes except for a bank of computers in vlan3. I have went as far as to delete the pool and recreate it, heck i even recreated the v lan and i am still having issues. Below are some snippets of the running config for review.
The DHCP Pool for the affected LAN:
ip dhcp pool Dev3

D-Link DIR-655 :: Disabling DHCP On Arris Router And Setting Static IP Address
Sep 9, 2012My old modem from Roadrunner (Time Warner) died and the service man replaced it with a Arris TG852 modem/router. then my problems began. I would like to have the Arris modem act like a modem and not a router. The network governed by the DIR works fine but none of the clients can connect to the internet. Below are the steps I have tried.in both steps below, The DIR is connected to the Arris using the Ethernet not the Wan port.
1. I tried disabling DHCP on the Arris router and setting a static IP address for the DIR router. This worked for a bit and then quit. Some of the computers said there were duplicate IP addresses on the network. If fact the same IP address showed up in the DNS list of the Arris and the DIR routers.. even though the Arris router had DNS disabled.
2. After reading other forums. I enabled DHCP on the Arris and set it to passout IP address between 192.168.0.2 and 192.168.0.99. I then setup the DOR to pass out addresses between 192.168.0.100 and 192.168.0.200. then moved the DIR into the DMZ of the Arris. Still no access to the internet.
