APPENDIX A
Troubleshooting
BLADE OS provides two main methods for monitoring HP GbE2c Ethernet Blade Switch (GbE2c)
network traffic, as well as a varietry of traditional network troubleshooting tools:
sFlow—Statistical flow monitoring for high-speed data ports.
Port Mirroring—Complete port data capture.
Other tools such as ping, traceroute, etc.
sFlow
The GbE2c supports sFlow technology for monitoring traffic in data networks. The switch includes
an embedded sFlow agent which can be configured to sample network traffic and provide
continuous monitoring information to a central sFlow analyzer.
Note – The switch is responsible only for forwarding sFlow information. A separate sFlow
analyzer is required elsewhere on the network in order to interpret sFlow data.
sFlow Statistical Counters
The GbE2c can be configured to send network statistics to an sFlow analyzer at regular intervals.
For each port, a polling interval of 5 to 60 seconds can be configured.
At the end of each configured polling interval, the GbE2c reports general port statistics (as found in
the output of the /stats/port <x>/if command) and port Ethernet statistics (as found in the
output of the /stats/port <x>/ether command).
