Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
For T1 links:
–
Valid range is 3 to 320.
–
For Link Warning monitoring, the default is 15.
–
For Link Removal monitoring, the default is 145.
For E1 links:
–
Valid range is 8 to 832.
–
For Link Warning monitoring, the default is 20.
–
For Link Removal monitoring, the default is 205.
• duration seconds—Number of seconds that a threshold must be exceeded to create a condition or
fallen below to clear a condition. Valid range is 1 to 600. The default is 10.
When specified with the lcv keyword, the duration must be configured after the LCV threshold.
For example, span warn lcv 55 duration 20 is a correct way to issue the command; span warn
duration 20 lcv 55 is not.
• set—Specifies that the values configured for the span command are to be used to set a condition.
• clear—Specifies that the values configured for the span command are to be used to clear a
condition.
Usage Notes
When configuring the LNM, please note the following:
• If the warn and remove keywords are specified without any other options, the LCV and PCV
thresholds and duration defaults are used to determine (set) and clear (clear) the condition.
• If the span command is issued with the set keyword specified (defining the LNM type and
parameters to use to determine a condition exists) and the command is not issued again with the
clear keyword specified (defining the parameters used to clear a condition), or vice versa, the values
configured for the threshold and duration are used for both.
• If the span command is issued without either the set or clear keywords specified, set is the default.
• The set and clear keywords can only be specified if the threshold and/or duration has been specified.
• If the PCV threshold is not configured (using the pcv keyword and value), the threshold is calculated
using Gaussian probability distribution that is representative of most noise environments.
• The following SYSLOG messages have been added for fault notification:
- %LNM-4- WARNEXCEED:Controller <Controller IF>, exceeded noise warning threshold
<int>, duration <int>
- %LNM-4- WARNIMPROVE:Controller <Controller IF>, noise improved below threshold
<int>, duration <int>
- %LNM-2-REMOVE:Interface <Serial IF> removed, noise exceeded threshold <int>,
duration <int>
- %LNM-2- RESTORE:Interface <Serial IF> restored, noise improved below threshold
<int>, duration <int>
- %LNM-2- REMEXCEED:Interface <Serial IF>, noise exceeded threshold <int>,
duration <int>
- %LNM-2- REMIMPROVE:Interface <Serial IF>, noise improved below threshold <int>,
duration <int>
