Cisco :: Windows 7 2008 Duplicate Static Address When Using 3750

Apr 30, 2013

ISE 1.1.3
Cisco 3750 switches
Windows XP / 7 / 2008 clients
 
I'm having some weird issues were if a client connects to a switchport and happens to be using a static IP address then the client warns of a duplicate address problem.  Also the client will then only show the default gateway within ipconfig even though the IP address / mask is still in the GUI network properties of the adaptor.  This is happening with Windows 7 and Windows 2008 devices.
 
Windows XP clients don't get the issue.
 
Some clients will use 802.1x native supplicant and some will be authenticated based on MAB.  Not noticed the problem with 802.1x clients but it always occurs on MAB.
 
I came across a similar issue here: URL
 
Going of that blog I tried using the "ip device tracking delay probe delay" command but the switches don't recognise the "delay" keyword.
 
The switches are 3750  switches running version 12.2(58)SE2.
 
All I have is  "count, interval, use-svi" as extra options.
 
Catalyst 4500 switch guide has  "delay" option but no "count, interval or use-svi".
 
The only way I have managed to avoid the problem is using the second solution which is a registry hack on each client.  This is fine for the odd server but not realistic when there will be hundreds of other clients.

Cisco :: LMS 4.0.1 - Duplicate IP Address Caused By ACE Active / Standby Setup?

Dec 17, 2011

I am using LMS 4.0.1 to monitor the data center network devices. I have two core switches, each core switch has an ACE module installed on it. I have configured many virtual context on each ACE module, and these ACE contexts are acting as primary and standby roles. The problem i faced with is LMS reports the virtual ip address configured on each ace context as duplicate ip address, and i didn't know how to deal with it. As to my understanding, this should be the normal behavior due to my setup, but how can i remove this alarm on LMS 4.0.1?

Cisco Firewall :: 5510 - Duplicate IP Address With ASA Inside Interface

Apr 5, 2012

We've had issues with our Exchange 2010 server (running on ESXi 4.1) since its default gateway was changed to our new ASA 5510.  They manifested as frequent Outlook client connection dropouts or as IP address conflicts whenever Exchange was rebooted.  The temporary fix was to disable the Exchange server NIC, bounce the ASA and enable the server's NIC again.  We saw poor performance from Exchange after a while again, but after some research and testing I realised that disabling proxyarp on the inside interface fixed the problem permanently.
 
However I've now realised that the client VPN no longer routes properly because proxyarp is disabled on the inside interface, so I still have a problem.

Cisco Switching/Routing :: Nexus 7000 Not Generating Log For Duplicate IP Address?

Sep 19, 2011

Recently I had came across 1 issue where one of the server IP  had conflicted with VIP of Nexus core switch. The blade server was physically  connected to Nexus Distribution switch which in turn connects to Nexus  core. Neither Nexus core nor distribution had generate any logs in  regards to IP conflict which ideally happens on Cisco catalyst  switches. I haven't find any document on cisco as well as on internet for  this issue . I dont know what logging need to enable on Nexus for this specific  case . There are different logging levels define for every feature like hsrp,  ip,monitor etc... 

We have Nexus 7k with latest release 4.2(6)  Software
BIOS: version 3.22.0
kickstart: version 4.2(6)

Cisco Switching/Routing :: 3750G Found Duplicate Mac-address Error / Not On More Than 1 Port

May 11, 2010

I've run in to this on 3750G's in a various sized stacks. We apply port security for a mac address on a single port (not existing on more than one port - that's  a different issue that appears in multiple posts already).In this case:
 
1) We do a 'sho mac address-table and see that the device with the mac address in question lives on one port, port 1/0/x.
 
2) We apply mac port security for this exact same mac address to the same port it is already attached to. switch(config)#int g2/0/2 switch(config-if)#switchport  port-security mac-address 001a.1ec8.abcd
 
3) Get this error: 'Found duplicate mac-address 001a.1ec8.abcd'.We again confirm that that is the only port on the entire switch that has this mac-address.Try the command again, same error.
 
4) We do a bunch of show commands, get in and out of the switch, go back and then try it again, and now it works, same command, same port and same mac address.
 
-Aging is default 300
-These are Cisco wireless AP's attached to the switch
-This occurs on different switches with different ports using different mac addresses, always same symptoms.

Could Windows 2008 Work As A NAS

Jan 13, 2012

My computer has today 3x2 TB WD Green disks and thay are really slowing my system down so now I need to move them to somekind of NAS.I was first lookin at the "Synology Disk Station DS411j" but then I found that I got some old hardware laying around (AMD 3200+ CPU, 1 GB ram,XFX GeForce 7600GT, Seasonic SS-300FT in a Thermaltake Xaser II chassi). So now I got some questions :

1. I was looking into running FreeNas on my NAS but if the NAS is crashing then it will be alot of work to get the data back? Is it right that its not possible to just mount a drive from the FreeNas in to my Windows7 computer and read the data?

2. If I install Windows 2008(not r2 that demands 64bits CPU) and then uses dynamic volums to get one big volume, what will happen if this Windows2008 craches? will it be able to place one of the disks in my windows7 computer and reda the data?

3. What happens if one disk i a dynamicvolume craches? will all data be lost?

4. Is there any sleepmode in Windows2008? If would be nice if the computer shutsdown at night and startsup when it is about to be used.

5. Will a finished product like the "Synology Disk Station DS411j" demand less power? Will I earn anything to buy the DS411j instead of my old hardware if we look on the economics?

Cisco :: LMS 4.1 Installation On Windows Server 2008 R2

Feb 7, 2012

As always, I am trying to install LMS 4.1 on windows server 2008 R2 and after the installation and login to the LMS I find the following:DCRServer is down or may not be completely up. Check if the DCRServer process is running.And after some troubleshooting I found that the LMS is not creating the CMF database and the other databases.
 
1. I have downloaded the installation file from Cisco website twice, so I do not think it is the file that is corrupted, also it is only evaluation license.

2. I have met all the prerequisites and requirement as in the documentation guides, but maybe there is something still wrong.

2. At the beginning, the ACS and the Windows domain was 2003. Now whit the change of the version of windows domain, What happens whit the configuration of the acs server as member server? I need reconfigure the member server configuration in the ACS Server?
