PXE-E76 Bad Or Missing Multicast Discovery Address

Jan 30, 2013

I've installed a Windows Server 2008 R2 Enterprise Edition with ADDS, DNS and DHCP server.Everything is configured correctly and running fine when I use an independent network.When I uninstall the DHCP on the server and connect it to my primary network with a Linux router (ClearOS) handling DHCP i get an error message on the client computer when trying to boot with PXE."PXE-E76: Bad or missing multicast discovery address".What do I need to do to make this work with my Linux router? Some port that has to be forwarded internally from the router to the WDS server?

Cisco :: LMS 4.2.3 Discovery Missing Wireless Controller Serial Numbers

Feb 25, 2013

just ran a discovery on a large network and found 49 wireless controllers (5500, 4400 and 2000 series) and none of them are showing the controller serial number. They are all running 7.0.235.0 and I found no bugs that match this issue.

Cisco Wireless :: Missing AP Multicast Mode IP Causing 3502i AP Radio Resets?

Jun 13, 2013

AP radio resets when the AP Multicast Mode IP is set 0.0.0.0 under the General Tab?
 
I rebuilt my lab controller and moved the management interface to a new subnet. Somehow, the AP Multicase Mode IP under the General Settings was removed. Afterwards, my AP's radios would reset every 2-3 minutes. After comparing my lab config to production, I noticed the IP was missing from that field. Setting the Multicast IP to 239.232.78.1 fixed the issue.

AP 3502i

This would definitely affect Office-Extend.

Each Of our distribution centers have a PIX501 and from there about 3-5 AP's each.

Cisco :: LMS 4.2 / W2K8 R2 - Discovery Not Working

Jul 12, 2012

LMS 4.2, W2K8 R2.I was having an issue with discovery adding devices to with corrupt information (seemingly random strings of characters in several fields).  While I was trying to clean this up a scheduled discovery kicked off and further exacerbated the issues I was having.  Frustrated, I deleted all entries from the discovery schedule until I could get things cleaned up.
 
Now I want to go back and troubleshoot the discovery process.  Trouble is, I can't get discovery to do anything anymore.  I disabled all modules but CDP.  I added a single seed IP address under the CDP configuration.  This is the address of a 3560V2 switch that is not in DCR.  When I started discovery it completed in about 2 seconds and didn't discover anything, including the seed device.  So I added another 3560V2 as a seed device under global settings.  Same results.  Thinking that it had been working using scheduled discovery, I set up a schedule and kicked it off that way.  Same results.  Finally I added one of these seed devices to DCR and let LMS fully learn about it.  Ran another discovery. Still no joy.
 
I started an SNMP debug on the seed devices before starting discovery.  I see the SNMP get coming from LMS, the switches respond and the discovery completes with 0 devices discovered.CS Discovery.log contains no meaningful information.  Only messages about "No appenders could be found for logger".

Cisco :: LMS 4.0.1 Devices Not Added To DCR After Discovery?

May 30, 2011

We have just installed LMS 4.0.1 and started to discover parts of the network. After the discovery process finished successfully -  100+ new devices were added to DCR message - I was able to see the devices by clicking on their number but when I go to Inventory-Add/Import/Manage Devices I cannot see any device in the Group that I created.If I restart the CiscoWorks Daemon Manager process the newly discovered devices are added to the custom Group. This seems like a bug as I had a LMS 4.0 evaluation installation a few months ago and device discovery was working fine meaning the devices were added immediately to the Inventory.

Cisco :: LMS 4.0 Reached Discovery For Devices

Jul 30, 2011

i am installing a CWLMS 4.0 and everything was good until i have reached the discovery for the devices, i am dealing with a bank setup and the branches is connected using layer 3 MPLS, branches are located behind the ISP router, so as a cdp neighbor i cant see anything but the ISP router  at my Core.
 
so i cant see the branches routers as neighbors to my (seed Device) Core, and i have tried to use the ping sweep and i could not reach them also. and also to add them manually as we were doing before in the earlier versions of CWLMS, using the Devices and Credintials, this option is removed from the LMS 4.0 as i have red in a document.
 
 1- snmp is configured on all devices.
2- access-list is configured on all devices.
3- i am able to reach the LAN Devices without any problems and the configuration is the same on all of the devices.

Cisco :: Device Discovery In Prime LMS 4.1

Sep 8, 2011

I am using CISCO PRIME LMS 4.1 for manage my network, i ran a device discovery job using a ping sweep on the ip ranges of my network, ie 192.168.1.0/24, 192.168.2.0/24 and so on... the discovery found all my devices, but it discovered duplicate devices with illegal ip Addresses, i.e.,
 
ip                                    device    
192.168.1.255               S1
192.168.2.0                    S1
192.168.2.1                    S1 (the real address)
 
all in reachable status.
 
I don't understand why the program adds that repeated illegal addresses.. How can I run the device discovery to avoid this problem?

I have a client with a 2112 WLC and 1252AG radios. The clients work fine, but an SNMP management server can not reach any of the clients over the wireless. Before the WLC and new AP's were installed, they were running older Cisco Autonomous AP's and had no problems with SNMP.  My monitoring system uses SNMP and it can reach the WLC just fine, so there doesnt appear to be any issues on the switched network. What can be blocking the SNMP on the WLC?

Cisco :: LMS 4.1 / Device Discovery Not Working Correctly

Jan 18, 2012

we are running CiscoPrime LMS 4.1 and I have the following problem.I have configured SNMP Settings as shown below (the order of the targets is exactly as it is configured on the server):As can be seen we use three different read community strings. I also have exluded a bunch of IP ranges and IPs from the filter settings. When I manually start discovery everything works fine, meaning that all devices in the above ranges that need to be discovered are discovered as "reachable". The problem appears in the scheduled discovery (happens once daily). In that case only the devices with Read Community snmp1, get discovered as "reachable". All other devices with Read community snmp2 & snmp3, as well as those that are excluded in the filter settings, are discovered as "unreachable".The discovery uses DCR as seed and seed devices are also configured.I also have a problem with PingSweep in the discovery, but I will open another discussion so that I don't complicate this one too much.

Cisco :: LMS 4.2 Cannot Enable End Host Discovery On Trunk

Mar 2, 2013

I have noticed that our LMS does not collect any information about wireless users connected to autonomous access points, although I can see the mac address of the wireless users on the switch (2960) Trunk port connecting to the AP via CLI. I can also get the IP address from the core switch. Even after selecting 'Perform Data Collection' on the AP in the topology, the Wireless End hosts report remains blank.
 
I am trying to enable the option 'End host Discovery on Selected Trunks' in the 'Acquisition configuration in Trunk' menu and after selecting the switch where the AP resides and clicking 'show Trunk' I get the message 'there are no trunks in the device(s) selected', although there are several trunk ports on this switch, other than the one connecting to the AP. The switch and the AP are managed by LMS. We are facing this problem with all Autonomus APs. We do not use WLSE. Is there something missing to discover these Wireless hosts ?

Cisco :: 1500 LMS4 Manual Device Discovery

Nov 7, 2011

I have a very special usecase with migrating devices from LMSv2.6 to v4.1 using DCR bulk import that was maintained manualy, not by discovering.The special thing is each device has its own SNMP-community and its about 1500 devices.RME discovery works fine, but I get the devices not discovered by DCR (CSDiscovery), because I need a minimal DCR discovery configration containing Seed and SNMP-settings. So I activated DCR as seed, but cant skip SNMP settings without an entry. But in this case I would need 1500 SNMP-lines that would be very unhandy. is in CSDiscovery-Settings a possibility to can leave SNMP settings untouched so it takes the credentials from the DCR, to can start DCR discovery?
