Cisco :: WS-C2960S-24TS-L User Tracking And VTP Mode Transparent
Mar 6, 2012
I am facing the following issue. In our environment we have a couple of WS-C2960S-24TS-L configured as stack. These switches are configured as VTP mode transparent.We are running LMS 4.1 and although UserTracking Acquisition works fine for all other switches, it only runs on demand for the above. The user tracking report for these switches shows only the MAC of the connected end hosts, without the respective IP address. The vlan I am interested in is configured on both the gateway (cisco 6509) and the switches, and the subnet is routable.Show arp on the gateway does show the "mac-ip address" binding, so I would have thought that usertracking would have been able to report both IP and MAC.
Why does usertracking only run on demand for the above switches in vtp mode transparent?Why does the UserTracking report show only the MAC and not the IP?Are the above issues related to the vtp mode? I have ruled out any connection to the switch-model, because we have recently installed the same switches in VTP mode client and User Tracking Acquisition works fine for them.

I need to compare a cisco ws-c2960s-24TS-s with a PowerConnect 6224, the scenario is to interconnect SAN ISCSI to 1G in RJ45.

We have two switches WS-C2960S-24TS-L running in stack with running IOS c2960s-universalk9-mz.122-55.SE3.We have connected two checkpoint devices on Gi1/0/24 and Gi2/0/24 with a simple configuration:
interface range GigabitEthernet1/0/24, gi2/0/24
switchport access vlan x
switchport mode access
spanning-tree portfast
On the devices log we get the following message:
%SW_MATM-4-MACFLAP_NOTIF: Host 0000.0000.fe21 in vlan x is flapping between port Gi2/0/24 and port Gi1/0/24
The mac-address 0000.0000.fe21 is not found on any checkpoint interface. "Show mac-address int gi1/0/24 or gi2/0/24" does not show the correct mac-address of the checkpoint interface connected to the port, but instead shows 0000.0000.fe21.Is there a bug in the IOS, something wrong with the switch config or does it have something to do with the checkpoint config?

I have a got a requirement where a 24 Port Switch should have 4 SFP's and all 4 should be used at a time, So I've chosen " WS-C2960S-24TS-L"
The transeiver should be GLC-LH-SM, so kindly let me no whether I would be able to use all 4 ports at a time or not.

I just received three WS-C2960S-24TS-Land three WS-C3560E-48TD-S switches that i entered the Express Setup on as usual. On two of each type of switch i found the default network that is used to facilitate the Express Setup was 10.0.1.1 and the others used an IP range of 10.0.2.1, i realized this is a small negligible at best difference though i need to provide management with an answer as to why there is a difference between the two and can’t find anything online as to why there is a difference or something that proves there should be a difference. All the documentation I find sounding Express Setup notes that the IP range will be 10.0.1.1 not 10.0.2.1

We have the following stack configuration:
Switch Ports Model SW Version SW Image------ ----- ----- ---------- ---------- 1 28 WS-C2960S-24TS-L 12.2(55)SE3 C2960S-UNIVERSALK9-M 2 28 WS-C2960S-24TS-L 12.2(55)SE3 C2960S-UNIVERSALK9-M 3 52 WS-C2960S-48TS-L 12.2(55)SE5 C2960S-UNIVERSALK9-M * 4 52 WS-C2960S-48TS-L 12.2(55)SE5 C2960S-UNIVERSALK9-M

I was wondering if it is possible to track and or log the changes that users make in in LMS 4.1. For an example if someone changed a configuration I want that being logged. I want to see what the person changed, when it's changed and who changed it.

what is the best way to do a acquistion on ip address on devices that appear to be dead until ping before LMS4.1 reports onn them. For example we run acquistion on a branch we do not see 172.20.12.51, howver we ping it from my desktop Claims unplugged when plugged in, and says "safe to remove" when I unplug the cableand then run user tracking and then it shows up.

I am trying to determine why hosts off our Nexus 7010s are being picked up in UT. Since LMS 4.0.1, UT should be supported on these devices.When adding the Nexus devices to DCR, provide the netadmin SNMP RO credential.When other SNMP RO credential is provided, user tracking will not collect end host data.I think I have this setup correctly as the device center test passes when cehcking snmp ro credentials.Our 7010s are running NX-OS 5.0(3) - earlier than the recommended version - might that cause issues? We are not using VRFs other than the default and management.
Here is my snmp section:
sh run | sec snmp
ip access-list copp-system-acl-snmp
10 permit udp any any eq snmp
10 permit udp any any eq snmp
20 permit udp any any eq snmptrap
[code]....

in LMS 4.1, under Monitor->Identity Dashboard, i have "user tracking summary" as a portlet, which tells me i have ~ 17,000 users. when i click the report, it pops up a screen that shows mac address, ip address, hostname, subnet, etc.
If i try to do ANY filtering, it returns 0 records. this could be from a specific IP, mac address, device name, or subnet. i have tried every type of record. every filter i attempt always ends with 0 records returned, even though in the unfiltered list they show up. It would be problematic to manually sort through 17,000 users looking for the particular records i need without the ability to use the filter.
how to filter the User Tracking report? is there some feature in LMS i don't own or have enabled to allow this filtering?

I have just got LMS 4.2 soft appliance up and running. When going to Inventory >> Acquisition summary, I get a HTTP 500 error with java. lang.Null Pointer Exception. That is obviously a bug somewhere (although the TAC engineer disagrees with me). I am just wondering if this is could have been caused by the fact that I have not done any user tracking on this LMS server yet? [code]

We are running LMS 4.3.2, it was running OK... but now we receive the following message:
"User Tracking Major Acquisition cannot be started as Network Topology, Layer 2 Services and User Tracking are disabled."
All processes are running. System restart and re-install the 4.3.2 update does not fix it. I think this happens after a device update, maybe FaultManagementDeviceUpdate...

I have an interesting problem at one of my customers. They are using LMS 4.0.1, but they have a problem with user tracking with SNMPv3. They using a very simple SNMP configuration, wich is the following: [code]
Now they have UT working well for their Ctalyst 4500 switches, and the half of the 6500s (They have 2950 switches as well, but for those UT with SNMPv3 is unsupported). So the problem is the following: they have 12 6500 switches, with the same IOS version (10 pieces of WS-C6506-E + SUP720-3B IOS: 12. 2 (18) SXF17 (IP Services), 2 pieces of WS-C6506 + SUP720-BASE IOS: 12.2(18)SXF17 (IP Services)). They have identical SNMP configuration on both devices. Based on the logs from LMS it seems that on the problematic switches for some reason LMS identifies the switchports as routed: [code]

I've another problem with our new LMS 4.0.1.We manage our devices with SNMP v3 but the user tracking don't want to work flawlessly.I've attached an example from our SNMP configuration. Basicly it's the same in our devices.
1st the problem was that no matter what I did the User tracking didn't want to find any host. I left it and worked on something else. After 2 weeks suddenly appeard couple of thousand end host.As earlier (LMS 2.6 or 3.2 with snmp v2) it is the same that LMS cannot differentiate normal end host and IP Phones although we have several thousand from both. But this is only one problem. The other is that there are switches with the same IOS and SNMP configuration and from one I get the UT data and from another one I didn't get anything. Only from some 4506 (aprox. 12-15) and 6506 (2) works and we have 20+ 4506 and 10+ 6506. Not to mention the other switches (couple of houndred 2960 and 3750).

I have a problem about user tracking for LMS 4.0.
For example:Switch 4506 send the endhosts for every VLAN that it has configured, except for one, but I can see that VLAN is configured over the switch.
are there problems directly with the connected endhosts over this VLAN or is it a problem about configuration for user tracking settings ?

If I have understand correctly, the IP address - mac address matching was made with the arp table of a cisco acces switch if it will made the L3.
My access switch wasn't used for L3 routing, only L2
It's possible to set user track to use the arp table of a firewall or a router for made this matching ?

Devices are 3750-24TS Switches, software version is 12.2(55)SE6. how to troubleshoot this issue, I have a pair of ports which are not bundling, no matter what. Is the same behavior with LACP or PAgP. In this outputs I have only the PAgP case.
Output is similar to:
Group Port-channel Protocol Ports
------+-------------+-----------+-----------------------------------------------
12 Po12(SD) PAgP Fa1/0/23(I) Fa1/0/24(I)
Configuration on ports is simple:
SW1:
interface FastEthernet1/0/24
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 12 mode desirable

I have a problem with LMS 4.2 user tracking.When I generate a report on all my network all mac address are ok but there is no Hostname/Ip address in the result, except for 2 equipments.the only difference between these 2 equipements and the rest of the network is that they are connected on a not routed vlan. All the other phones, computers are connected on a routed vlan.I have a Nexus 5k as core and 2960 as access. Routing between vlans is done with the NexusMy DNS server is ok and reachable.

I am experiencing an issue with end host being discovered on a cisco 4510. Anything connected to modules 9 or 10 are not discovered in User Tracking. The switch is running: Cisco IOS Software, IOS-XE Software, Catalyst 4500 L3 Switch Software (cat4500e-UNIVERSALK9-M), Version 03.02.01.SG RELEASE SOFTWARE (fc4).

I am using lms 3.2.1 and CM 5.2.2. I have even enabled ping sweep but the hosts IP never show on the user tracking report. I can not see any Available Subnets/Available Sources on Configure Subnet Acquisition and Ping Sweep windows. When I try to enable End host discovery on Trunks and click Show Trunks comes a message: "There are no Trunks in the device(s) selected", but every access device is connected to the nexus core via a Port channel:
interface Port-channel1
description sw-ser-core01 Po12
switchport trunk native vlan 998

I have an LMS 3.2.1 server running user tracking collection starting at 11:30am. We also use InterMapper to monitor switches. Right around the time UT collection is running, InterMapper starts to alert about "No SNMPv2c response".

New install discovered router and switches at same location with no issues. However when running an acquisition on those switches most fields are populated except the ip address of end host associated with port. Mac address, port speed, etc. but no ip address info on per port basis. Using snmp v3 if that makes a difference.

Does Cisco have any plans to incorporate the CiscoWorks User Tracking Utility into LMS Prime 4.2 or any newer version of LMS? This tool is very useful in identifing where a computer or device is located on a switch. I know SolarWinds just came out with their own version of the User Tracking utility, and I am wondering if Cisco is going to continue on with theirs.

We are using Catalyst 3750 with 12.2(44)SE. We have two stack configured, one with IP routing enabled. When we try to run an Acquisition Action on IP routing enabled stack, from Admin> Collection Settings> User Tracking, the system replies with an error "Failed to start acquisition: Device unreachable. Please enter a valid device". Acquisition starts successfully when we try with the other stack. We are going to investigate!

I have a problem with User tracking. After a restart of the daemon manager or a reboot of the server the end host table is empty. All end hosts then have to be discovered again. is there any possibility to backup and restore the UT-Database?

We just deployed some Catalyst 3750X-48PF-L switches. I noticed that the user tracking report doesn't work normally.The switches have C3KX-10Gb NM modules, and all access port are 1 Gbit. But in the User Tracking report, I see devices found on Fa0/43 for example (this is because the previous switch was a Catalyst 2960. I deleted the old switch and add the new 3750X, so this could not be the cause of the problem).I installed all the patches that are available for LMS 4.0.1.

I have installed LMS 4.0.1 again. Now LMS is running on a Windows 2008 R2, 64 bit. Using Custom Reports from Reports> Report Designer> User Tracking to create an end host report I get this error message: "The syntax is not valid: the system cannot find the path specified". Anyway, the report is created but I’m not able to edit or delete: it is not listed on Available Custom Reports.

We are running LMS Prime 4.2.3 on a Softappliance. We have a Cisco Switch behind a Non Cisco Layer-3 Device. In the end host tabe we see only the MAC-Addresses of the host connected to this switch. No IP-Address. The corresponding IP-Addresses are in the ARP-Table of this non Cisco Layer-3 Device. The arp table can also be read by snmp. Is it possible to get the ip address in the UT End Host Table in such an environment?
