[07/23-11:00:08:SPECMGR]-D-Channel Noise Power (1/10 dbmv) :
-197.
The following command output example displays what happens when the ingress
noise power increases causing the error rate to exceed the error threshold on an
upstream port:
[07/23-11:01:58:SPECMGR]-D-Error Rate: 0.0000 %, ErrorWord : 0,
TotalWord : 3723
[07/23-11:01:58:SPECMGR]-D-Channel Noise Power (1/10 dbmv) :
-152.
[07/23-11:02:08:SPECMGR]-D-Monitor Channel IfIndex = 7 :
[07/23-11:02:18:SPECMGR]-D-Monitor Channel IfIndex = 7 :
[07/23-11:02:18:SPECMGR]-D-Error Rate: 25.8228 %, ErrorWord :
816, TotalWord : 3160
[07/23-11:02:18:SPECMGR]-D-Channel Noise Power (1/10 dbmv) :
-84.
[07/23-11:02:20:SPECMGR]-D-Updating specTimers
The following command output example displays what happens when the spectrum
manager initiates the first hop action (the hop action rule is 1 with a priority of 30):
[07/23-11:02:38:SPECMGR]-D-Monitor Channel IfIndex = 7 :
[07/23-11:02:38:SPECMGR]-D-Error Rate: 1.3425 %, ErrorWord : 41,
TotalWord : 3054
[07/23-11:02:38:SPECMGR]-D-Channel Noise Power (1/10 dbmv) :
-68.
The following command output example shows that the first hop action succeeded to
set a new frequency, and the desired noise power level is restored.
[07/23-11:03:07:SPECMGR]-N-Set to new frequency 28000000 for
channel ifIndex = 7 .
[07/23-11:03:08:SPECMGR]-D-Monitor Channel IfIndex = 7 :
[07/23-11:03:08:SPECMGR]-D-Error Rate: 0.0000 %, ErrorWord : 0,
TotalWord : 3781
Note: Notice that the noise power level increases.
