Missing IP-Address in User Tracking End Host Table

[mchristen]

Hello,

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?

Regards,

Martin

No that is not possible. Several cisco fw devices doing layer 3 have the same issue.

It seems importing an arp table is very complicated  :-|

You could create an interface in each vlan on you switch. Then using scripting you could ping from the switch the entire subnet.

This would fill the arp table, it stays there for about 4 hours and IP addresses would appear in the UT it it runs during that time

Cheers,

Michel
