GS108T and GS110TP Smart Switch Software Administration Manual The Current Server IP Address field is blank if no servers are configured (see RADIUS Server Configuration on page 148). The switch supports up to three configured RADIUS servers. If more than one RADIUS servers are configured, the current server is the server configured as the primary server. If no servers are configured as the primary server, the current server is the most recently added RADIUS server. To configure global RADIUS server settings: 1. In the Max Number of Retransmits field, specify the value of the maximum number of times a request packet is retransmitted to the RADIUS server. Consideration to maximum delay time should be given when configuring RADIUS max retransmit and RADIUS timeout. If multiple RADIUS servers are configured, the max retransmit value on each will be exhausted before the next server is attempted. A retransmit will not occur until the configured timeout value on that server has passed without a response from the RADIUS server. Therefore, the maximum delay in receiving a response from the RADIUS application equals the sum of (retransmit times timeout) for all configured servers. If the RADIUS request was generated by a user login attempt, all user interfaces will be blocked until the RADIUS application returns a response. 2. In the Timeout Duration field, specify the timeout value, in seconds, for request retransmissions. Consideration to maximum delay time should be given when configuring RADIUS max retransmit and RADIUS timeout. If multiple RADIUS servers are configured, the max retransmit value on each will be exhausted before the next server is attempted. A retransmit will not occur until the configured timeout value on that server has passed without a response from the RADIUS server. Therefore, the maximum delay in receiving a response from the RADIUS application equals the sum of (retransmit times timeout) for all configured servers. If the RADIUS request was generated by a user login attempt, all user interfaces will be blocked until the RADIUS application returns a response. 3. From the Accounting Mode menu, select whether the RADIUS accounting mode is enabled or disabled on the current server. 4. Click Cancel to cancel the configuration on the screen and reset the data on the screen to the latest value of the switch. 5. If you make changes to the page, click Apply to apply the changes to the system. RADIUS Server Configuration Use the RADIUS Server Configuration page to view and configure various settings for the current RADIUS server configured on the system. To access the RADIUS Server Configuration page, click Security  Management Security, and then click the RADIUS  Server Configuration link. 148 | Chapter 5: Managing Device Security

GS108T and GS110TP Smart Switch Software Administration Manual

The Current Server IP Address field is blank if no servers are configured (see

RADIUS

Server Configuration

on page

148). The switch supports up to three configured RADIUS

servers. If more than one RADIUS servers are configured, the current server is the server

configured as the primary server. If no servers are configured as the primary server, the

current server is the most recently added RADIUS server.

To configure global RADIUS server settings:

In the

Max Number of Retransmits

field, specify the value of the maximum number of

times a request packet is retransmitted to the RADIUS server.

Consideration to maximum delay time should be given when configuring RADIUS max

retransmit and RADIUS timeout. If multiple RADIUS servers are configured, the max

retransmit value on each will be exhausted before the next server is attempted. A

retransmit will not occur until the configured timeout value on that server has passed

without a response from the RADIUS server. Therefore, the maximum delay in receiving

a response from the RADIUS application equals the sum of (retransmit times timeout) for

all configured servers. If the RADIUS request was generated by a user login attempt, all

user interfaces will be blocked until the RADIUS application returns a response.

In the

Timeout Duration

field, specify the timeout value, in seconds, for request

retransmissions.
