There is a need to identify IP address of the connected host.
With DHCP snooping, it works on Local Switch, with RO and RW community for SNMP
However, it does not work with switches found on remote LANs. The switch has been discovered and collected by the Campus Manager with similar configuration of SNMP and DHCP snooping, however these switches fail to identify.
for this IP identification, What mechanism does the UT use? is it DHCP snooping mib.
However i can find the IP address in the DHCP snooping binding, but seems that UT does not see them.
The dynamic User Tracking feature uses DHCP snooping to get the IP address for end hosts. This assumes that a MAC address notification trap was sent for the MAC when the end host connected to the switch.
For acquisitions, UT reads the ARP caches from all Data Collected routers, and attempts to map MAC to IP. Therefore, if you're not using dynamic UT, you need to make sure that a router on the same VLAN as those remote end hosts is properly Data Collected, and that there are no views which would block the ipNetToMediaTable.
