I have a WLC 2504 with 5 AP licenses for which I have installed an adder license via GUI. The installation completed successfully, but I still cannot view the new license. The maximum number of APs is still showing as 5 and in fact I cannot add more that 5 APs. I tried installing the license file again, but now I get a "duplicate" error.
I have just moved to the 3750X switch and have connected it to a 6509E. From the beginning I was having OSPF encryption errors, followed by flood warnings, LSA issue's, duplicate IP's which is baffling me.
There are no IP's which match on either switch however the 3750X was continually power recycling causing the interfaces drop continually.Even after disconnecting from the 6509 the 3750X continue to behave in the same manner. Could there be some issue with this switch?
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.

We are trying to upgrade throughput on ACE appliance 4710, getting below mentioned Error. We got license file from Cisco first license is for 0.5 to 1g, 2nd 1g to 2g and 3rd one is for 2g to 4g.
Our environment is critical, hence we are doing upgrade on Secondary appliance first. for that we are first isolating Secondary appliance by disabling up link switch port.

I am having Cisco 3845 series router with c3900-universalk9-mz.SPA.151-4.M2.bin IOS . I want to install new Licence on it for DATA. When i am trying to install licence on it i am facing the error "% Error: License installation failed with error: XML parsing failed".
I have a duplicate router ID problem that is confusing to me. A 6509 and 4510 swich both show the same router ID, but only the 6500 has the router ID IP address configured in it. We are running EIGPR. The 6509 has L0 as 164.72.239.1 configured, which is it's router ID. The 4510 doesn't have 164.72.239.1 configured on it, yet that's what it's router ID is. Below are a few show commands displaying this - and as you can see from the 'show run | include 239' from the 4510 there is no 164.72.239.1 configured on it:
6509 chassis
interface Loopback0ip address 164.72.239.1 255.255.255.255end RS6509-Core-A#sh ip eigrp topIP-EIGRP Topology Table for AS(1)/ID(164.72.239.1) Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply, r - reply Status, s -

why the 4510 has that router ID?
I know I can configure a different router ID on the 4510, but I'm curious as to why it is the way it is.
In the process of setting-up a E2500 Linksys router, I set-up my secured network which is working fine but also (I do not know how I did this??) set-up the same named network but it is unsecured. How do I delete this unsecured network.Do I need to set-up the router again?
I'm using .01 firware and I notice that after I reboot the router I get duplicate filenames on the HD attached to it with the video files. What folder or config file can I delete so it will do a clean rescan? please fix the E4200 media server in .02 firmware
What's the difference between VPN Plus license and Security Plus license. I have new 5520 shipped with VPN Plus license.Also does it require a seperate license for Anyconnect for Mobile and AnyConnect Essentials.
I’m stuck in some problem with installation of LMS4.0 in customer site.
- we purchase a LMS4.0(CWLMS-4.0-100-K9) but couldn’t install it on Windows server 2008 R2 64bit because those things don’t support each other. - I need to upgrade the LMS4.0 to LMS4.2 that is supporting Windows server 2008 R2 64bit. - So, I ordered following items via product update tool (url...) [code]
- In this status, how to install LMS4.2 with license for 100 devices? If I install R-PI12-BASE-K9 first, can i enter a licese for 100 devices for CWLMS-4.0-100-K9 into PI1.2?
The router 1841 is connected directly to the layer switch. the network diagram is below:
Office A --> Switch (L3) --> Router 1841 --> Internet --> Office B
However, when I transfer the file from Office A to office B, the speed very slow ( only around 40 kb/second), and there are an input error and CRC error:
Cisco-R1841#sh interfaces FA0/1 FastEthernet0/1 is up, line protocol is up Hardware is Gt96k FE, address is 0019.e02f.03dd (bia 0019.e02f.03dd)
I'm seeing a TON of traffic in my ASA logs (via ASDM) indicating the following:"Duplicate TCP SYN from inside: (valid internal address of one of our laptops)/50164 to inside: (address on our other subnet, still trying to trace it)/9100 with different initial sequence number"This looks like an attack to me, likely someone's downloaded something they shouldn't have and got an infected laptop. Why it's trying to "call home" to something inside our network is what puzzles me, though.Is there any VALID reason I would see these sort of messages in my log?
We have LMS 4.2 installed and added devices;Now if for example a device is not reachable we get two messages with same failure ;only the component name is different
- one event with "dns" in component name - one with "dns(ip)" in component name dns == hostname
Everyday a few of the computer will error with "A duplicate name exists on the network:" A quick Google search shows the same answer EVERYWHERE on the internet. So I changed the names of a few of the computers too something I knew was unique. Still though the problem persists/ it afters the two XP bases computers the most, but my main workstations (windows 7 sp1) has had this error a few times, although it appears to have left for a while. I have a feenas server but Active directory is not turned on.My router is a e4200. I was using DHCP server on there (and would very much still like to) although I have turning it off, rebooted both the router and the computers but to no avail.
My customer is seeing these Errors coming up on one of his 2504 WLC's (ver7.3) The MAC's and IP addresses Mentioned seem to be completely fictitious as the customers IP plan is way off these subnets and the vendor lookup tool cant resolve the MAC addresses.I can confirm that there is no conflict.I've seen them appear on other 2504's across his network on seperate occasions.
I am having peculiar issue in my setup. I recently replaced my ASA 5505 (8.2.1) with ASA 5510 (8.4.3). Everything works fine for a while suddenly I see some of the servers will not be reachable from the LAN all the servers gateway is my switch. If I check on my Dell switch the particular server's arp entry on the connected port is same as ASA physicall MAC. If im reverting to 5505 ASA everything goes smooth without any issue.
I got some issues with my CISCO ASA, the thing is that when I add a new rule on the device this rule duplicate and goes to the bottom. We already tried to delete the duplicate rule but it always show an error.
In case I configure duplicate IP addresses to the same VLAN(two interfaces in VLAN 1100 have IP address 192.168.2.2) I see following ARP messages rapidly(those six messages were received in less than 2ms time-frame)
I am using 2 anchor controllers 5508 as DHCP server. Anchor controller A is primary and anchor controller B is secondary. From time to time, client will complain "duplicate IP address error" when they try to connect guest wireless.First question: both anchor controller should have a recorder of IP address which is assigned to each PC, right?Second question: is there any way this type of issue can be avoided?
I am getting the following error messge on Cat4500:

WAP A is setup to allow the Mac's of A and B to repeat its signal. The issue starts about 1-2 minutes after I set B and C to client/repeater and select A in site survey then save the settings. Obviously its weird that only our 2003 servers are getting this error.

I have two 2960's in this new environment that I am administering. I am receiving a message on one unit (Designate it 2960-2) of %IP-4-DUPADDR: Duplicate address 192.168.168.8 on Vlan1, sourced by 3037.a63e.540. The "sourced by" address is the 2960-1. I do not know how these units were originally set up. How can I determine where the duplicate address is originating from.When I perform an ARP -a the address that corresponds to the 192.168.168.8 is the mac address of the ethersvi interface on the 2960-1.

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?
I have a setup where a spoke (cisco 1841) is sending a multicast feed to a hub (cisco 2951) via a DMVPN tunnel on the Internet. The feed arrives on interface fa0/0 of the cisco 1841 and is forwarded to the tunnel interface. It is about 160,000 kbit/s and 18 pps. This always looks the same:

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.
