Changing bottleneck parameters
13
The alerting parameters indicate whether alerts are sent, and the threshold, time, and quiet time
options.
For a trunk, you can change the parameters only on the master port.
1. Connect to the switch and log in as admin.
2. Enter the bottleneckmon
--config command to set the alerting and sub-second latency
criterion parameters.
Enter the bottleneckmon
--configclear command to remove any port-specific alerting and
sub-second latency criterion parameters and revert to the switch-wide parameters.
Example
The following example disables alerts on port 1, excludes ports 2, 3, and 4 from bottleneck
monitoring, and changes the alerting parameters on ports 2 and 3. The bottleneck
--status
command shows the settings for these ports. Note that this example changes the alerting
parameters on ports 2 and 3, even though they are excluded from bottleneck detection.
switch:admin> bottleneckmon --config -noalert 1
switch:admin> bottleneckmon --exclude 2-4
switch:admin> bottleneckmon --config -alert -lthresh .99 -cthresh .9 -time
4000 -qtime 600 2-3
switch:admin> bottleneckmon --status
