TACACS+ Configuration 
The TACACS+ Configuration page contains the TACACS+ settings for communication 
between the switch and the TACACS+ server you configure via the inband management port.

communications between the GS728TS, GS728TPS, GS752TS, or GS752TPS and the 
TACACS+ server. The valid range is 0–128 characters. The key must match the key 
configured on the TACACS+ server.
2.  In the Connection Timeout field, specify the maximum number of seconds allowed to 
establish a TCP connection between the GS728TS, GS728TPS, GS752TS, or GS752TPS 
and the TACACS+ server. The valid range is 1–30 seconds.
3.  Click Cancel to cancel the configuration on the screen and reset the data on the screen to 
the latest value of the switch.
4.  If you make any changes to the page, click Apply to apply the new settings to the system.
