M6100, M5300, and M7100 Series Managed Switches
The Current Server IP Address field is blank if no servers are configured (see Configure
a RADIUS Server on page 548). The switch supports up to three configured RADIUS
servers. If more than one RADIUS servers is configured, the current server is the primary
server. If no servers are configured as the primary server, the current server is the most
recently added RADIUS server.
8. In the Source Interface list, select the interface to use for RADIUS.
Possible values are as follows:
• None
• Routing interface
• Routing VLAN
• Routing loopback interface
• Service Port
By default, VLAN 1 is used as source interface.
9. In the Max Number of Retransmits field, specify the maximum number of times a request
packet is retransmitted to the RADIUS server.
The valid range is 1– 15. The default value is 4.
Consider the maximum delay time when you configure the RADIUS maximum retransmit
and RADIUS time-out. If multiple RADIUS servers are configured, the maximum
retransmit value on each is exhausted before the next server is attempted. A retransmit
does not occur until the configured time-out value on that server passed without a
response from the RADIUS server. Therefore, the maximum delay in receiving a
response from the RADIUS application equals the retransmit times the time-out for all
configured servers. If the RADIUS request was generated by a user login attempt, all
user interfaces are blocked until the RADIUS application returns a response.
10. In the Timeout Duration field, specify the time-out value, in seconds, for request
retransmissions.
The valid range is 1–30. The default value is 5.
Consider the maximum delay time when you configure RADIUS maximum retransmit and
RADIUS time-out. If multiple RADIUS servers are configured, the maximum retransmit
value on each is exhausted before the next server is attempted. A retransmit does not
occur until the configured time-out value on that server passed without a response from
the RADIUS server. Therefore, the maximum delay in receiving a response from the
RADIUS application equals the retransmit times the time-out for all configured servers. If
the RADIUS request was generated by a user login attempt, all user interfaces are
blocked until the RADIUS application returns a response.
11. Select the Accounting Mode Disable or Enable radio button.
This specifies whether the RADIUS accounting mode is enabled or disabled on the
current server.
12. Select the RADIUS Attribute 4 Disable or Enable radio button.
