Incoming lnet message can be delayed for seconds if it can match
any of LNet Delay Rules.
User can add/remove/list Delay Rule by lctl commands:
- lctl net_delay_add
Add a new Delay Rule to LNet, options
<-s | --source SRC_NID>
<-d | --dest DST_NID>
<<-r | --rate RATE_NUMBER>
<-i | --interlval SECONDS>>
<-l | --latency DELAY_LATENCY>
- lctl net_delay_del
Remove matched Delay Rule from LNet, options:
<[-a | --all] |
<-s | --source SRC_NID>
<-d | --dest DST_NID>>
- lctl net_delay_list
List all Delay Rules in LNet
- lctl net_delay_reset
