ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual 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. The value of the maximum number of times a request packet is retransmitted. The valid range is 1 - 15. Consideration to maximum delay time should be given when configuring RADIUS maxretransmit and RADIUS time-out. 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 time-out 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 time-out) 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 time-out value, in seconds, for request retransmissions. The valid range is 1 - 30. Consideration to maximum delay time should be given when configuring RADIUS maxretransmit and RADIUS time-out. 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 time-out 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 time-out) 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. Use RADIUS Attribute 4 to enable or disable RADIUS attribute 4. Default value is Disable. This is an optional field and can be seen only when RADIUS attribute 4 is enabled. It takes IP address value in the format (xx.xx.xx.xx). Table 6-81. Field Current Server Address Number of Configured Servers Description The Address of the current server. This field is blank if no servers are configured. The number of RADIUS servers that have been configured. This value will be in the range of 0 and 3. 434 | Chapter 6. Managing Device Security

ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual

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. The value of the

maximum number of times a request packet is retransmitted. The valid range is 1 - 15.

Consideration to maximum delay time should be given when configuring RADIUS

maxretransmit and RADIUS time-out. 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 time-out 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 time-out) 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 time-out value, in seconds, for request

retransmissions. The valid range is 1 - 30.
