Overview
The dashboard consists of RADIUS and DHCP and automatically switches every 30 seconds. Double-clicking one of the buttons at the top creates a pin icon, which freezes the screen. In the RADIUS dashboard, the status of the operating system is also displayed.
The
icon in the upper-right corner of the dashboard allows you to toggle automatic refresh on/off by clicking it. The 
icon, as shown in the image on the right, allows you to configure what is displayed in the RADIUS dashboard. Accounting and authentication processing represent the number of columns displayed on the dashboard, and selecting an NAS-ID will only display information from the selected NAS-ID on the dashboard.

System Status
The top-left corner of the RADIUS dashboard displays the system's memory (RAM), disk, and CPU load. Clicking on "System Details (
)" takes you to the detailed page. The "Services" section displays "Normal" if all operational services are running, and it shows "Warning" if one or more services are in a stopped state.
If an external authentication server, such as an "LDAP server" or an "external database," is used for external RADIUS authentication, the connection status of LDAP and external database is shown on the left in RADIUS dashboard.
The 
icon indicates all connections are normal and the 
indicates warning. "Warning" signifies that there is a connection problem with an external server.
Hourly Counts of Post-Authentication
This represents the number of users authenticated or not per hour. Green bars represent Access-Accept, while red bars represent Access-Reject. The bars represent today's counts, and the line represents yesterday's counts.
Proportion of Post-Authentication
This indicates the ratio of users who were processed with Access-Accept (green pie chart) and Access-Reject (red pie chart).
- Access-Accept
- local: Authenticated through the Local database
- pta: Authenticated through an external database
- ldap: Authenticated through external LDAP
- proxy: Proxy authentication (authenticated through an external authority)
- Access-Reject
- einv: User-Name or User-Password is incorrect
- epahase2: Attempted phase-2 authentication using MSCHAPV2 in the Android environment with external database, LDAP authentication, or Proxy authentication
- simul: Exceeded simultaneous connection limit
- ecert: Client certificate error
- ban: Authentication denied by reject2ban
Post-Authentication
Displays users who have been authenticated or not in real-time. A red icon preceding the username indicates Access-Reject. Clicking on the username provides detailed information.
Accounting (Today's Ranking of Traffic Usage)
This information displays the ranking of users who have used the most data among those connected to the network after successful authentication.
DHCP
DHCP Allocation
It displays how many IP addresses are assigned and in lease for 72 hours.
The chart shows the IP Lease and the Allocation 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 reason of reply for DHCP requests in the PostDHCP 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.
PostDHCP
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 failure means in the DHCP failure messages.
To get the details of a log, Click the MAC address on each row.
