User Tracking LMS 4.0

[adamgibs7]

Hello,

I can't find all the end user either hostname or IP Address or username but i can see them by MAC address. The switches on which they are connected they are discovered and DATA has been collected for that switch.still the Ip address and hostname and username are not found,

Any hints please

Find out what router is the default gateway of the end hosts.

Then get this router managed in LMS.

Cheers,

Michel

Hello

The router is Juniper firewall. But i m gettting IP 's for some host and also for  hostname for some end user but no username.

Thanks

That is the root cause of your issue.

LMS needs the arp table to make the link between the mac and the IP addresses but it won't ask the juniper for its arp table.

Hopefully a future version of LMS will ask standard mibs like the ARP table from any detected device, cisco or not.

Maybe your switch can be a router as well, then you can resolve the issue as the IP addresses will be in the switch ARP table.

Cheers,

Michel

I only have a basic understanding of how it works

I don't think campus tries to find out what could be the default gateway for a particular switch.

I think it will take in all arp tables from all managed cisco devices and puts this in a big table.

So if he then finds the mac address anywhere in that table then he can make a relation with an IP address and will do a DNS lookup to get a hostname.

So from time to time the devices that have an IP and a hostname are not only speaking to their default gateway but also to a managed cisco device.

That cisco device then has an ARP entry with the mac and IP address.

Hope this is more or less clear.

Cheers,

Michel
