AAA-SERVER-MIB Set Operation
The AAA-SERVER-MIB Set Operation feature allows you to extend and expand your ability to configure authentication, authorization, and accounting (AAA) servers using the CISCO-AAA-SERVER-MIB. Using this feature, you can do the following:
Create and add new AAA servers.
Modify the “KEY” under the CISCO-AAA-SERVER-MIB.
Delete the AAA server configuration.

Finding Feature Information
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table.
Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required.
Prerequisites for AAA-SERVER-MIB Set Operation
AAA must have been enabled on the router, that is, the aaa new-model command must have been configured. If this configuration has not been accomplished, the set operation fails.
Restrictions for AAA-SERVER-MIB Set Operation
Currently, the CISCO SNMP set operation is supported only for the RADIUS protocol. Therefore, only RADIUS servers in global configuration mode can be added, modified, or deleted.
Information About AAA-SERVER-MIB Set Operation
CISCO-AAA-SERVER-MIB
The CISCO-AAA-SERVER-MIB provides that statistics reflect both the state of the AAA server operation with the server itself and of AAA communications with external servers. The CISCO-AAA-SERVER-MIB provides the following information:
Statistics for each AAA operation
Status of servers that are providing AAA functions
Identities of external AAA servers
CISCO-AAA-SERVER-MIB Set Operation
In Cisco IOS XE Release 2.1, the CISCO-AAA-SERVER-MIB supports both the get and set operations. With the set operation, you can do the following:
Create or add a new AAA server.
Modify the KEY under the CISCO-AAA-SERVER-MIB. This “secret key” is used for secure connectivity to the AAA server, which is present with the network access server (NAS) and the AAA server.
Delete the AAA server configuration.
How to Configure AAA-SERVER-MIB Set Operation
No special configuration is required for this feature. The Simple Network Management Protocol (SNMP) framework can be used to manage MIBs. See the section Additional References for a reference to configuring SNMP.
Verifying RADIUS Server Configuration and Server Statistics

Configuration Examples for AAA-SERVER-MIB Set Operation
RADIUS Server Configuration and Server Statistics Example
The following output example shows the RADIUS server configuration and server statistics before and after the set operation.
Before the Set Operation
Router# show running-config | include radius-server host ! The following line is for server 1. radius-server host 172.19.192.238 auth-port 2095 acct-port 2096 key cisco2 ! The following line is for server 2. radius-server host 172.19.192.238 auth-port 1645 acct-port 1646
Server Statistics
Router# show aaa servers RADIUS: id 2, priority 1, host 172.19.192.238, auth-port 2095, acct-port 2096 State: current UP, duration 25s, previous duration 0s Dead: total time 0s, count 7 Authen: request 8, timeouts 8 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 2 Author: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Account: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Elapsed time since counters last cleared: 5m RADIUS: id 3, priority 2, host 172.19.192.238, auth-port 1645, acct-port 1646 State: current UP, duration 5s, previous duration 0s Dead: total time 0s, count 2 Authen: request 8, timeouts 8 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 4 Author: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Account: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Elapsed time since counters last cleared: 3m
SNMP Get Operation to Check the Configuration and Statistics of the RADIUS Servers
aaa-server5:/users/smetri> getmany 10.0.1.42 casConfigTable casAddress.2.2 = 172.19.192.238 casAddress.2.3 = 172.19.192.238 casAuthenPort.2.2 = 2095 casAuthenPort.2.3 = 1645 casAcctPort.2.2 = 2096 casAcctPort.2.3 = 1646 casKey.2.2 = casKey.2.3 = ! The following line shows priority for server 1. casPriority.2.2 = 1 ! The following line shows priority for server 2. casPriority.2.3 = 2 casConfigRowStatus.2.2 = active(1) casConfigRowStatus.2.3 = active(1) aaa-server5:/users/smetri>
SNMP Set Operation
The key of the existing RADIUS server is being changed. The index “1” is being used. That index acts as a wildcard for addition, deletion, or modification of any entries.
Change the key for server 1:=> aaa-server5:/users/smetri> setany -v2c 10.0.1.42 public casAddress.2.1 -a 172.19.192.238 casAuthenPort.2.1 -i 2095 casAcctPort.2.1 -i 2096 casKey.2.1 -o king casAddress.2.1 = 172.19.192.238 casAuthenPort.2.1 = 2095 casAcctPort.2.1 = 2096 casKey.2.1 = king aaa-server5:/users/smetri>
After the Set Operation
After the above SNMP set operation, the configurations on the router change. The following output shows the output after the set operation.
Router# show running-config | include radius-server host radius-server host 172.19.192.238 auth-port 1645 acct-port 1646 ! The following line shows a change in the key value to “king.” radius-server host 172.19.192.238 auth-port 2095 acct-port 2096 key king
Router# show aaa servers RADIUS: id 3, priority 1, host 172.19.192.238, auth-port 1645, acct-port 1646 State: current UP, duration 189s, previous duration 0s Dead: total time 0s, count 2 Authen: request 8, timeouts 8 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 4 Author: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Account: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Elapsed time since counters last cleared: 6m ! The following line shows a new server with new statistics. RADIUS: id 4, priority 2, host 172.19.192.238, auth-port 2095, acct-port 2096 State: current UP, duration 209s, previous duration 0s Dead: total time 0s, count 7 Authen: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Author: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms Transaction: success 0, failure 0 Account: request 0, timeouts 0 Response: unexpected 0, server error 0, incorrect 0, time 0ms
