Configuring the ACE as a Client of a RADIUS, TACACS+, or LDAP Server
Setting the Global RADIUS Server Number of Retransmissions

The syntax of this command is as follows:
radius-server deadtime minutes
The minutes argument is the length of time that the ACE skips a nonresponsive
RADIUS server for transaction requests. Valid entries are from 0 to 1440 minutes
(24 hours). The default is 0.
For example, to globally configure a 15-minute dead-time interval for RADIUS
servers that fail to respond to authentication requests, enter:
host1/Admin(config)# radius-server deadtime 15
To set the RADIUS server dead-time interval to 0, enter:
host1/Admin(config)# no radius-server deadtime 15
By default, the ACE sends one authentication request to a RADIUS server before
it declares the server to be unresponsive and contacts the next server in the group.
Use the radius-server retransmit command to globally change the number of
times that the ACE sends an authentication request to a RADIUS server. If all
servers in the group are unavailable for authentication and accounting, the ACE
tries the local database if you configured it as a local fallback method using the
aaa authentication login or the aaa accounting default command. If you do not
have a fallback method, the ACE continues to contact one of the AAA servers
listed in the server group.
The ACE applies this global retransmission value to those RADIUS servers for
which a value is not individually configured by the radius-server host command.
The syntax of this command is as follows:
radius-server retransmit count
The count argument is the number of times that the ACE attempts to connect to a
RADIUS server before trying to contact the next available server. The range is
from 1 to 5 times. The default is 1.
For example, to globally configure the number of retransmissions to 3, enter:
host1/Admin(config)# radius-server retransmit 3
