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.

History for the AAA-SERVER-MIB Set Operation Feature

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

Before using the AAA-SERVER-MIB Set Operation feature, you should understand the following concepts:

•CISCO-AAA-SERVER-MIB

•CISCO-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

Before Cisco IOS Release 12.4(4)T, the CISCO-AAA-SERVER-MIB supported only the "get" operation. Effective with this release, the CISCO-AAA-SERVER-MIB supports the set operation. 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.

SNMP values can be verified by performing the following steps.

SUMMARY STEPS

1. enable

2. show running-config | include radius-server host

3. show aaa servers

DETAILED STEPS

 
Command or Action
Purpose

Step 1 

enable

Example:

Router> enable

Enables privileged EXEC mode.

•Enter your password if prompted.

Step 2 

show running-config | include radius-server host

Example:

Router# show running-config | include radius-server host

Displays all the RADIUS servers that are configured in the global configuration mode.

Step 3 

show aaa servers

Example:

Router# show aaa servers

Displays information about the number of requests sent to and received from authentication, authorization, and accounting (AAA) servers.

Configuration Examples for AAA-SERVER-MIB Set Operation

This section includes the following example:

•RADIUS Server Configuration and Server Statistics: Example

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

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
