CiscoWorks LMS 4 configuration

[AZaburdyayev]

Hello!

I am recently setup LMS. Now have questions on which cannot find answer in documentation.

In DCR( Device Credential and Repository) I should add user name,password and enable secret. What protocol does Cisco Works will use (telnet, ssh)?

I am started device discovery, LMS found 4 devices, 1 available and 3 unreachable.

All unreachable devices are pingable from my host, I can connect to them using telnet. Why lms mark them as unreachable?

I have hub and spoke topology all wan routers are in 2-3 hops away from my central router( transit router not mine).

How to make LMS draw network topology ?

All devices marked as unreacheble, but from LMS host I can ping them ant use telnet( all credential on DCR and they are valid).

Please help, any help is appreciated.

LMS doesn't use ping to see if a devices is reachable, it uses SNMP.

In CSCOpx\object\jt\bin you find some tools to test this via cli on the server

For the network topology LMS uses SNMP & CDP. If two connected devices have both the other device in their CDP table then they become connected in the topology

Thanks!

But how In this case LMS can monitor WAN Links ? There is no CDP on such link and all ,my devices are unconnected, how I should tell  LMS that they are connected and measure WAN link speed ?

I haven't tried this, but I think it is possible to add some tunnel interfaces and create a tunnel between the routers that are yours and then enable CDP on that tunnel. No need for the real traffic to go via this tunnel!

The topology is not the real, but you get a "logical" picture.

The wan link speed is not so easy to measure, and it is not something LMS does for you "out of the box". There are ways to generate and measure load between router you manage in the IPM module using IPSLA tests.

Since you can only measure the traffic on the interface of devices where you have SNMP access you can only see the speed of you uplink to the local provider, not to a specific remote site.

defently it is not so easy to do on all my links. Is it possible to make LMS draw graphs like mrtg do ?

[Michel Hegeraat · Accepted solution]

Yes, you can create a "poller" for any kind of OID and get a graph of that.
