RADIUS server retransmition occurs when the connection to the RADIUS server fails or a response pack is not received by the UCME. When this happens, the default behaviour of the UCME is to try to reconnect three more times. This can lead to memory problems on the UCME, if there is a high number of packets failing. To avoid this, the global retransmit count can be amended accordingly, and it can also be configured 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 | conf t |
| 2 | radius-server retransmit 0 |
| 3 | exit |
| 4 | wr |
To change a specific RADIUS server settings, log in to the UCME CLI and enter the following commands:
| Step | IOS Commands |
|---|---|
| 1 | conf t |
| 2 | radius server SERVER_NAME |
| 3 | retransmit 3 |
| 4 | exit |
| 5 | wr |
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.
