You can use either the WebUI or the CLI to configure how often the switch will generate a DNS request to cache
the IP address for a RADIUS server identified via its fully qualified domain name (FQDN).
Using the WebUI
1. Navigate to the Configuration > Security > Authentication > Advanced page.
2. In the DNS Query Interval (min) field, enter a new DNS query interval, from 1-1440 minutes, inclusive.
3. Click Apply.
Using the CLI
(host)(config) #aaa dns-query-interval <minutes>
Configuring Username and Password for CPPM Authentication
The switch authenticating to CPPM is enhanced to use configurable username and password instead of
support password. The support password is vulnerable to attacks as the server certificate presented by CPPM
server is not validated.
In the WebUI:
1. Navigate to Configuration > Security> Authentication>Servers.
2. Under RADIUS Server, select the server name.
3. Enter the cppm_username and cppm_password in the CPPMcredentials option.
4. Click Apply.
In the CLI:
(host)(config) #aaa authentication-server radius
