Rate-limiting RADIUS packets
NAS enables you to allow or reject RADIUS dynamic authorization packets based on the rate-limiting value that you specify.
NAS lets you to congure number of RADIUS dynamic authorization packets allowed per minute. The default value is 30 packets per
minute. NAS discards the packets, if the number of RADIUS dynamic authorization packets in the current interval cross the congured
rate-limit value.
Enter the following command to congure rate-limiting:
rate-limit number
NAS considers the rate limit change value from the next interval period. The range is from 10 to 60 packets per minute. The default is
30 packets per minute.

Conguring time-out value
You can congure a time-out value for the back-end task to respond to CoA or DM requests.
This setting enables the DAS to determine the amount of time to wait before a back-end response is received. The default value is 10
minutes.
Enter the following command to congure the time-out value:
da-rsp-timeout value

Role-Based Access Control
With Role-Based Access Control (RBAC), access and authorization is controlled based on a user’s role. Users are granted permissions
based on their user roles, not on their individual user ID. User roles are created for job functions and through those roles they acquire the
permissions to perform their associated job function.
