Dell NetWorker 19.9 Administration Guide
NetWorker TCP/IP keep-alive parameters
In NetWorker, the TCP/IP keep-alive parameters are enabled by default for connections in between "nsrjobd" and "nsrexecd", and "nsrindexd" and save in case of client direct save. You can modify the TCP IP keep-alive parameters to prevent any potential connection failures.
The table lists the default TCP IP keep-alive parameters values in
NetWorker. These values override the default operating system keep-alive parameters.
| TCP Parameter | Value in second |
|---|---|
| Keepalive time | 900 |
| Keepalive interval | 10 |
| Keepalive count | 20 |
