Global TACACS+ settings
On the TACACS+ tab of the Administration > Account Management > Remote Authentication page, click Settings to open the Global TACACS+ Settings page.
Specify the TACACS+ service under which authorization roles/flags will be found on the TACACS+ server. The TACACS+ server administrator must configure this service. Check with the TACACS+ server administrator if you need a service defined exclusively for NetProfiler users.
You can also specify the number of seconds that the NetProfiler waits for a connection attempt to succeed before moving on to the next server in the list of configured servers.
