Occurred : # of times this event has occurred since last clear or reboot
Flags : (*) Not all applications responded in time with there count values
In(cluded): Set to Y(es) if one or more targets filter includes this event
Notified : # of times this event has occurred when 'Included' was Y(es)
The output of the command:
show log counters stp.inbpdu.drop
is similar to the following:
Comp SubComp Condition Severity Occurred In Notified
------- ----------- ----------------------- ------------- -------- -- --------
STP InBPDU Drop Error 0 Y 0
Occurred : # of times this event has occurred since last clear or reboot
Flags : (*) Not all applications responded in time with there count values
In(cluded): Set to Y(es) if one or more targets filter includes this event
Notified : # of times this event has occurred when 'Included' was Y(es)
Displaying Debug Information
By default, a switch does not generate events of severity Debug-Summary, Debug-Verbose, and Debug-
Data
unless the switch is in debug mode. Debug mode causes a performance penalty, so it should only
be enabled for specific cases where it is needed. To place the switch in debug mode, use the following
command:
enable log debug-mode
Once the switch is in debug-mode, any filters configured for your targets still affect which messages are
passed on or blocked.
Logging Configuration Changes
ExtremeWare XOS allows you to record all configuration changes and their sources that are made using
the CLI by way of telnet or the local console. The changes cause events that are logged to the target
logs. Each log entry includes the user account name that performed the change and the source IP
address of the client (if telnet was used). Configuration logging applies only to commands that result in
a configuration change. To enable configuration logging, use the following command:
enable cli-config-logging
To disable configuration logging, use the following command:
disable cli-config-logging
CLI configuration logging is disabled by default.
Using sFlow
sFlow® is a technology for monitoring traffic in data networks containing switches and routers. It relies
on statistical sampling of packets from high-speed networks, plus periodic gathering of the statistics. A
User Datagram Protocol (UDP) datagram format is defined to send the information to an external entity
