First, you need to configure SNMP Community on the devices that we want to poll. With the help of such requests, ISE obtains information about the physical interface, CDP, LLDP and ARP. This probe sends SNMP requests (SNMP Queries) to network access devices to receive data from the SNMP MIB (Management Information Base). For example, documentation on configuring SNMP on Cisco 4500 switches is available at link… In general, this probe does not have to be turned on, since all transmitted data and even more can be received through the RADIUS Probe. In this case, you need to configure SNMP Traps on network devices, this will allow you to get information about connected and disconnected hosts. You can get a lot of valuable information from the RADIUS Probe, and it can be very useful for troubleshooting. NAS-Port – Name of the physical interface Īcct-Session-ID – Unique accounting number (Accounting ID) Īcct-Session-Time – Activity time in seconds Īcct-Terminate-Cause – The reason for terminating the connection. NAS-IP-Address – IP address of the device sending the authentication request User-Name – the name of the authenticated user Some of the RADIUS attributes used for profiling are: Additionally, this probe can collect attributes by listening to traffic from CDP, LLDP, and even DHCP protocols. Cisco ISE collects RADIUS attributes from EAP messages between the RADIUS server and clients.
One of the most popular profiling methods is RADIUS.
