The imRAD has two dashboards. One is for the RADIUS and the other is for the DHCP.
Each dashboard switches automatically in 30 seconds and you can stop the switching by clicking again one of the buttons at the top of the dashboard.
DHCP Assignment
It displays how many IP addresses are assigned and in lease for 72 hours.
The chart shows the IP Lease and the Assignment ratio and the lease ratio is always less or equal to the assignment ratio .
Current DHCP Pool Availability Top 5
This list displays the availability of each DHCP pool of the order in which availability is small.
The availability 0 means there are no more IP addresses to assign.
DHCP HPM(Hits per minute) / LPM(Leases per minute)
The HPM stands for Hits per minute and means how many DHCP requests the DHCP server receives in a minute.
The LPM stands for Leas per minute and means how many IP addresses are assigned to the DHCP clients in a minute.
The DHCP server does not reply to all DHCP requests from clients because the IP address for some requests may not find in the DHCP pool.
So the LPM is always less or equal to the HPM.
The HPM that is very greater than the LPM means the DHCP server could not assign IP addresses to many DHCP clients because of the lack of IP addresses in a DHCP pool or no DHCP pools for the requests. In this case, You must check the failure of reply for DHCP requests at the Post DHCP Log.
DHCP IP Address Assignment
It displays the assigned, released, declined, and expired IP addresses in real-time.
You can view the details of the IP address by click one of IP address in the list.
Post DHCP
It shows the result of processing the requests of DHCP clients.
By default, it only displays the results of failure(recommended) and you can change the setting using the CLI to save all results(failure and success).
The failure means that a DHCP server dose not reply to DHCP clients because of the specific reason. You can make sure what the reply means in the DHCP reply results.
To get the details of a log, Click the MAC address on each row.
RADIUS Accounting
It displays how many users are granted their network access and how much network traffic is generated from the granted users.
- DEFAULT: Authenticated by the Proxy(via remote RADIUS server).
- LOCAL: Authenticated at the Local RADIUS.
- Online User: The number of online users.
To get the details of a log, Click the Username on each row.
Postauth
The Postauth means the result of processing of RADIUS ACCESS-REQUEST in imRAD RADIUS. This lists the Postauth in real-time.
The message in each row indicates the result of an ACCESS-REQUEST and "Access-Accept" message means that a user is authenticated.
To get the details of a log, Click the Username on each row.
