RADIUS server retransmition happens when the connection to the RADIUS server fails or a response pack is not received by the UCME. The default behaviour is for the server to try 3 more times if the connection/response fails. This can lead to memory problems on the UCME, if there is a high number of packets failing. It is possible to change the global retransmit count and also set it differently for each RADIUS server.
To change the global setting, log in in the UCME CLI and enter the following commands:
| Step | IOS Commands |
|---|---|
| 1 | |
| 2 | |
| 3 | |
| 4 |
To change a specific RADIUS server setting, log in to the UCME CLI and enter the following commands:
| Step | IOS Commands |
|---|---|
| 1 | |
| 2 | |
| 3 | |
| 4 | |
| 5 |
With the above configuration, the specific server for which these settings apply will try to resend data if there is a failure, whilst the others will give up if the initial packet is lost.
