LMS 3.0 Important

1-I have remote sites and main branch connection between remote sites to main branch is MPLS

2-Connection between main branch to remote sites over 2 ISP

My question

I need real time monitor with out enable GRE tunnel between main branch to remote site

If the router down in remote site from any ISP I need the router will be reed

I need this action in topology map

I don't need this action by mail or by syslog

Re: LMS 3.0 Important

If a device becomes SNMP unreachable, then Campus will detect that on its next Data Collection or polling pass. Campus Manager is NOT a fault management application, and its map is not updated in real time.

By default, the polling interval is every two hours. Campus 5.0 and higher has a critical devices poller which runs every five minutes by default. After that update runs, you may have to manually refresh the topology map. The N-Hop portlet should update based on your refresh interval.

If you see devices not getting updated with their status, make sure that they are actually becoming SNMP unreachable when Campus runs its Data Collection or polling cycle. If so, enable frontend, framework, core, and corex debugging under Campus Manager > Admin > Debugging Options > Data Collection. Wait for a new polling cycle or Data Collection to run, then look at the ani.log for errors.

All that said, it would be better to use a more real-time fault management application like DFM, HPOV Network Node Manager, NetView, etc. to let you know when this branch site goes offline.

Re: LMS 3.0 Important

It depends on the interface type, but in general DFM manages all interfaces by default. To confirm if your interfaces are managed, go to DFM > Device Management > Device Details, and bring up the Detailed Device View on your devices. Check to make sure the managed state of your interfaces is true. If not, set the state to true, then go to DFM > Configuration > Polling and Thresholds > Apply Changes to apply the changes.

After that, DFM will poll the interfaces to make sure they are up. If they go down, you will get an alert under DFM > Alerts and Activities > Alerts and Activities. Within the Alert you will have an OperationallyDown event pertaining to each down interface.

Cisco Employee

Re: LMS 3.0 Important

The Alerts and Activities Display is designed to be monitored by operators. It automatically refreshes. The polling interval is customizable, but by default, it is four minutes.

I do not understand the second question.

Cisco Employee

Re: LMS 3.0 Important

The AAD will show alerts for ALL devices. An alert will appear for each device having a fault. The AAD can be filtered on device type, device names, and alert IDs. DFM, unlike the rest of LMS, has limitations on the number of supported ports and interfaces. If you only wanted to manage the two serial interfaces on 1300 devices (i.e. 2600 interfaces), you could do that all with one instance of DFM.

Re: LMS 3.0 Important

AAD = Alerts and Activities Display

You can filter the output on the fly by clicking on the filter button at the top of the AAD screen. You can create custom filter groups by going to DFM > Configuration > Other Configurations > Alerts and Activities Defaults, and creating groups there.

Cisco Employee

Re: LMS 3.0 Important

AAD automatically refreshes every 30 seconds. This cannot be customized.

Cisco Employee

Re: LMS 3.0 Important

AAD only shows alerts. Devices which have no faults will not be shown in AAD. You can get a list of all devices DFM is managing under DFM > Device Management > Device Status. Any device in a Known state is being properly managed by DFM.

Cisco Employee

Re: LMS 3.0 Important

DFM monitors all devices in a Known state. If the devices are healthy (e.g. they are reachable, and have no down interfaces) then you will not see any alert for them in AAD. DFM is still managing and monitor those devices, though.

Re: LMS 3.0 Important

1-Please can you tell me all things about uses topology map?

2-if I put all network 1300 device in critical poler and make it every 2 sec is this wrong I need advice

Cisco Employee

Re: LMS 3.0 Important

The criticial devices poller is designed for no more than 30 devices. You will cripple Campus if you drop the poller and add that many devices.

The main use for the Topology Map is network documentation. That is, use it for visualizing layer 2 topology, spanning-tree forwarding and blocking ports, traffic patterns (if using RMON data), and potential misconfigurations in the network.

Now I need ask about if I can configure DFM to monitor 2 serial interfaces for all remote branches and make real time monitor report in screen

Re: LMS 3.0 Important

I can monitor this report with out generate or refresh I mean real time monitor

And can I customize this view for 2 cloud 192.18.0.0& 192.29.0.0

Re: LMS 3.0 Important

I need to ask about I have 2 serial interfaces in all branches to connect for main branch one serial have 172.18.0.0 & second serial have 172.29.0.0 can I customize report real time monitor for this interfaces

Re: LMS 3.0 Important

Ok but I have problem with DFM some alerts come with operation down when I try ping this device I get response can DFM when get alert with interface down after interface is up can DFM send alert to tell me the interface is up

Cisco Employee

Re: LMS 3.0 Important

Alerts are composite entities. They are composed of one or more events. An event is an atomic problem on a device. An OperationallyDown event will clear automatically when DFM detects that the device or interface is once again reachable. Once all of the events within an alert clear, then the alert itself will clear.

You will see a cleared status in AAD for 30 minutes before the alert is removed from AAD. At such time, you will only be able to see it in Fault History for the next month.

It's important to note that DFM will treat any managed interface which is administratively up but operationally down as being OperationallyDown. If you have such interfaces on your devices that should be down, then be sure to "shutdown" those interfaces. DFM also pings each IP address on a device for reachability. If all the IP addresses on a given device are not ICMP reachable, then you will need to go to DFM > Device Management > Device Details, and unmanage the unreachable IP addresses. This is only doable in DFM 3.0 and higher. Note: you CANNOT unmanage the IP address by which you added the device to DFM or the device will go into a Questioned state.

Re: LMS 3.0 Important

Hi Joe

Please I attached file please I need you tell me why this event not clear from AAD

And please if you can explain some of this event

And thank for your help

Cisco Employee

Re: LMS 3.0 Important

I can't tell you why these are not clearing since I don't know what the underlying events are, nor do I know what is happening in your network. But, as I said in my previous post, alerts will clear when ALL of the underlying events have cleared. So go through each alerts' events, and see why they are being triggered, then either correct the problem on the device, or change your threshold setting.

Re: LMS 3.0 Important

Dear Joe

I need to ask you about some point

1- Can I use hosts file instead DNS and I need example for 1 router have 5 interfaces I will put all interfaces or I will put one interface in this hosts file if I can use hosts file

2-in topology we have MPLS between branches and can't enable JRE tunnel you have any solution to get link between them

3- can I discover node with out use loop back interface and I need to know what happen if I put ( example router have 2 serial interface I will enter the 2 interfaces in discovery like 172.18.1.1 &172.29.1.1)

4-can Cisco works help me to obtain monitoring screen to monitor the devices and to display the status of the device when it becomes up or down real time monitor I need up and down I don't need use AAD

Cisco Employee

Re: LMS 3.0 Important

1. Yes. You can add the one interface by which you manage this device into the hosts file.

2. If you cannot get CDP on a link between two campuses, then you will not get a link drawn on the Topology Map. There is no workaround for that.

3. Discovery will eventually fall back to serial interfaces if you select the use loopback option. You don't need to multiple seed device entries per device. Really, you only need one seed device per campus, or one seed device per disjoint area of your network.

4. If you don't want to use DFM's Alerts and Activities Display, then there is nothing in LMS that will give you fault information for devices in a real-time view.

Re: LMS 3.0 Important

Hi Joe

Now I can't display in AAD the up devices and I have problem in network because MPLS all site obtain as separate

1-Can I add 1 router in CS by 2 serial interfaces to obtain in topology map as 2 routers?

2-if you have any solution I can use to real time monitor to up and down interfaces please tell me

New Member

Re: LMS 3.0 Important

joe

are you there

Cisco Employee

Re: LMS 3.0 Important

You can add the same device twice in DCR provided each of the hostname, display name, and IP are different. However, applications like RME and Campus will detect the device is the same. Campus won't duplicate the device unless there is a problem.

Unlike a graphical fault management application, DFM doesn't show green, "all-is-well" icons to indicate a device is healthy. You just don't see any alerts from a healthy device in AAD (or the status of an alert will be Cleared indicating a problem has been resolved).

The upcoming LMS 3.1 release will offer integration between DFM and Campus, so there will be some visual indication of faults on the topology map, but that is not scheduled until the end of next month.

New Member

Re: LMS 3.0 Important

Sorry joe for all these question but I need know because customer when ask me

1-I run automatic discovery and I put seed device with 2 serial interfaces for each remote site and enable loopback interface why in topology the device appear with ip for loopback interface

2- DFM for fault devices its ok where I can monitor normal devises this question customer ask me I need answer to tell hem

Cisco Employee

Re: LMS 3.0 Important

If you selected to use loopback when determining the management IP, then that's what Discovery will do. It will add the device to DCR with the loopback IP. Campus will then use that IP to manage the device.

I don't understand the second question.
