Hi, sorry to the time it took to answer your question.
I believe we did configure the network-admin role in Radius with our network admins group, so that we could login as admins. However, that was a long time ago and things are fuzzy for me how we solved this issue.
Sorry if I could not be of better help!

Hi, We've detected strange behaviour from our Cisco Prime Infrastructure. We did a upgrade from 1.3 to 2.0 last friday and all looked good and well. However, we noticed that our SNMP locations were missing from our network devices. With some research, we saw that the SNMP locations were in the startup-config, but not in the running-config. We also noticed that our LMSuser (which we use for identifying that Prime is logging into the switch) changed something in the config: Oct 2 22:00:50 192.168.57.220 7566: Oct 2 22:00:49: %SYS-5-CONFIG_I: Configured from console by lmsuser on vty1 (172.20.250.1) So we set the SNMP location on a couple of switches to test our theory. And the next evening when Prime does its collection routine, it removes the SNMP location again. Is this a bug or is this a new setting in Prime? Thanks in advance!

Hi Rolf, I searched across the Cisco site and didn't pay too much attention of the different types of 3560 switches. Because I saw the commands in IOS, I immediately thought that they would work. (Assumptions...) Well, I did some research and it turns out that what I said before, wasn't completely true. According to my collegues, all switches that have this problem, have been replaced old Cisco 2811 routers last year. So that's why they said it did work before.

Hi there, I've got a rather odd situation going here. In our company we use NetFlow to measure network traffic. Some of our NetFlow devices have gotten an upgrade and stopped working. When I look at the configuration, I see: ip flow-cache timeout active 1 ip flow-export source Vlan3 ip flow-export version 9 ip flow-export destination 172.29.1.12 9996 interface GigabitEthernet0/48 switchport access vlan 3 switchport mode access switchport nonegotiate ip flow ingress ip flow egress logging event link-status speed 100 duplex full mls qos trust dscp no snmp trap link-status no cdp enable spanning-tree portfast end I can confirm that the NetFlow Analyzer is working, as some of the network devices are still sending their NetFlow information. VLAN3 is where the outside IP is configured. Interface G0/48 is member of that VLAN. The switch that I'm troubleshooting: Switch Ports Model SW Version SW Image ------ ----- ----- ---------- ---------- * 1 52 WS-C3560G-48PS 15.0(1)SE3 C3560-IPBASEK9-M Flow export v9 is enabled for main cache Export source and destination details : VRF ID : Default Source(1) 192.168.100.81 (Vlan3) Destination(1) 172.29.1.12 (9996) Version 9 flow records 0 flows exported in 0 udp datagrams 0 flows failed due to lack of export packet 0 export packets were sent up to process level Vlan3 ip route-cache flow ip flow ingress GigabitEthernet0/48 ip flow ingress ip flow egress I'm kinda unsure what goes wrong here. I believe to have configured everything right. Can somebody help me?

Hi, Unfortunately, I no longer use LMS anymore as we switched to Cisco Prime Infrastructure 1.3. We got an answer from our supplier stating that LMS 4.2.2 did not officially support Archive Management for the Nexus platform, but Prime Infrastructure did. I checked that out and migrated to Prime Infrastructure. I did not solve the problem but if you have the chance, use Prime Infrastructure. It's so much easier to setup and Nexus archive management is supported. My jobs haven't failed yet. :-) Sent from Cisco Technical Support iPad App

Hi Roger, I have no idea how to correct this in LMS. As far as I know, there is no option to correct this. I also contacted our supplier with this question and they stated that the Nexus portfolio is only supported for Fault Management and Network Topology Layer 2: http://www.cisco.com/en/US/partner/docs/net_mgmt/ciscoworks_lan_management_solution/4.2.2/device_support/table/lms422sdt.html I find this hard to believe, as we are running a couple of Cisco Nexus 7000 switches which Archive Management can easily extract the running-config and startup-config from. Why this seems impossible for the Nexus 5000 switches, is beyond me.

Unfortunately, this is not working. Both the Device Credential Verification and sync archive fails. Have you got another idea how to solve this problem?

I understand that this seems to be the problem, that's the problem I'm having. I have the right credentials on the switch and in the Device Credentials Set. No other type of switch in our network has this problem, except for the Nexus 5000 series. All the other switches use exactly the same username and password. Loggin in to the SF-DERA-01 via de Cisco LMS server with SSH works, so I find it hard te believe that this is a credentials problem.

Hi Ferraro, I did as you asked, but with no success. Device Name Read Community Read Write Community SNMPv3 Telnet Enable by Telnet SSH Enable by SSH SF-DERA-01 Ok Ok No Value To Test Protocol not configured. Did Not Try Incorrect Did Not Try We do not use Telnet on our devices. However, we do use SSH and I checked that the LMS server can login into the SF-DERA-01 switch for its CLI. I use the same user for all our network devices. I use only one Device Credential Set. As a last resort, I used a username line of a working Cisco Nexus network device and pasted it in the SF-DERA-01, but with no success. Could this be some sort of bug or am I missing something here?

Hi, I’m currently at a loss here: In our organisation we have multiple Nexus 5000 switches, which Cisco LMS 4.2.2 cannot get the running-config and startup-config from with the Archive Management process. When it does try to get them, I get a error as follows: *** Device Details for SF-DERA-01 *** Protocol ==> Unknown / Not Applicable Selected Protocols with order ==> TFTP,SSH,SCP Execution Result: RUNNING CM0151 PRIMARY RUNNING Config fetch failed for SF-DERA-01 Cause: Failed to fetch config using TFTPFailed to establish SSH connection to 172.20.253.21 - Cause: Authentication failed on device 3 times. Action: Check if protocol is supported by device and required device package is installed. Check device credentials. Increase timeout value, if required. Verify if firewall configuration permits traffic from LMS to the device and vice versa for the protocols configured in Admin > Collection Settings > Config > Config Transport Settings. However, I have no problems when I try to login from our LMS server (GRNAP401) to the N5K switch. Our LMS server is the Appliance version. We have a user (lmsuser) for the LMS server that is configured on numerous switches, like Catalyst and other Nexus family switches. We only have this problem with the N5K switches.

I have more switches in the 172.20.254.0/24 subnet including other Nexus switches, so I can say that TFTP and SSH are working. Can somebody help me with this? Thanks in advance!

You need to give a seed device (often this will be your core switches) so that LMS can discover from there. Also, use CDP and Ping Sweep to discover more devices besides the ones you add as a seed device. After that, run the discovery process a couple of times so that more devices will be added each time. Use Ping Sweep for the devices that cannot be reached via CDP. Hope this helps!

Hi, Thanks for responding so quickly. On one pair of N7K, I see as much as 900 state changes. I think you're right with the interval 500 timeout 3. I'll going to tweak this and get back to you.
